BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0021]
(Overall system configuration)
First, a digital laboratory system according to the present embodiment will be described. FIG. 1 shows a schematic configuration of a digital laboratory system 10 according to the present embodiment, and FIG. 2 shows an appearance of the digital laboratory system 10. As shown in FIG. 1, the lab system 10 includes a line CCD scanner 14, an image processing unit 16, a laser printer unit 18, and a processor unit 20, and the line CCD scanner 14 and the image processing unit 16 The laser printer section 18 and the processor section 20 are integrated as an output section 28 shown in FIG.
[0022]
The line CCD scanner 14 is for reading a frame image recorded on a photographic film such as a negative film or a reversal film, and includes, for example, a 135-size photographic film, a 110-size photographic film, and a transparent magnetic layer. It is possible to read a frame image of a photographic film (240-size photographic film: so-called APS film) or a photographic film of 120-size or 220-size (Brownie size). The line CCD scanner 14 reads the frame image to be read by the line CCD, and outputs image data.
[0023]
Here, the photographic film is a film in which a negative image or a positive image is visualized by subjecting a subject to development after photographing.
[0024]
FIG. 4 shows the APS film 102. As shown in FIG. 4, the APS film 102 is provided with a magnetic recording layer 116. In the magnetic recording layer 116, printing conditions and the lens type of the photographed lens are also recorded. This lens type is used when correcting an image read from the APS film 102 for aberration. For example, in the case of a film with a lens, the lens type may be recorded in advance at the time of manufacture, or may be recorded from the camera at the time of photographing. Further, optical information (barcode 112) is recorded in advance (for example, at the time of manufacture) on the APS film 102, and the barcode 112 indicates a film ID.
[0025]
The image processing unit 16 receives image data (scanned image data) output from the line CCD scanner 14 and obtains image data obtained by photographing with a digital camera and a document other than a frame image (for example, a reflection document). Externally input image files such as image data obtained by scanning with a scanner and image data generated by a computer (for example, input via a storage medium such as a memory card, or input via a communication line. And the like from an information processing device.
[0026]
The image processing unit 16 performs image processing such as various corrections on the input image data, and outputs the image data to the laser printer unit 18 as recording image data. Further, the image processing unit 16 outputs the image data on which the image processing has been performed to an external device as an image file (for example, outputs the image data to a storage medium such as a memory card, or transmits the image data to another information processing device via a communication line). ) It is also possible.
[0027]
The laser printer unit 18 includes R, G, and B laser light sources, irradiates the photographic paper with laser light modulated in accordance with the recording image data input from the image processing unit 16, and scans the photographic paper by scanning exposure. Record the image in Further, the processor unit 20 performs each process of color development, bleach-fixing, washing, and drying on the photographic paper on which the image is recorded by the scanning exposure by the laser printer unit 18. Thus, an image is formed on the printing paper.
[0028]
(Configuration of Image Processing Unit 16)
Next, the configuration of the image processing unit 16 will be described with reference to FIG. The image processing section 16 is provided with a line scanner correction section 122 corresponding to the line CCD scanner 14. The line scanner correction unit 122 includes a signal processing unit including a dark correction circuit 124, a defective pixel correction unit 128, and a light correction circuit 130 corresponding to the R, G, and B image data output in parallel from the line CCD scanner 14. Three systems are provided.
[0029]
The dark correction circuit 124 converts the data (data representing the dark output level of each cell of the sensing unit of the line CCD 116) input from the line CCD scanner 14 into each cell while the light incident side of the line CCD 116 is shielded from light by the shutter. For each pixel, correction is performed by subtracting the dark output level of the cell corresponding to each pixel from the scan image data input from the line CCD scanner 14.
[0030]
In addition, the photoelectric conversion characteristics of the line CCD 116 vary from cell to cell. In the bright correction circuit 130 at the subsequent stage of the defective pixel correction unit 128, the line CCD 116 reads the adjustment frame image with the line CCD 116 in a state where the entire frame is set to have a fixed density frame image. For each cell based on the image data of the frame image for adjustment input from the line CCD scanner 14 (the density variation of each pixel represented by this image data is caused by the variation of the photoelectric conversion characteristic of each cell). The gain is determined, and the image data of the frame image to be read input from the line CCD scanner 14 is corrected for each pixel according to the gain determined for each cell.
[0031]
On the other hand, in the image data of the frame image for adjustment, when the density of a specific pixel is significantly different from the density of other pixels, there is some abnormality in the cell corresponding to the specific pixel of the line CCD, The specific pixel can be determined as a defective pixel. The defective pixel correction unit 128 stores the address of the defective pixel based on the image data of the adjustment frame image, and stores the defective pixel data in the image data of the frame image to be read input from the line CCD scanner 14. Generates new data by interpolating from data of surrounding pixels.
[0032]
In the line CCD, since three lines (CCD cell rows) are sequentially arranged at predetermined intervals along the photographic film transport direction, the R, G, and B component colors are output from the line CCD scanner 14. There is a time difference in the timing at which the output of the image data is started. The line scanner correction unit 122 delays the output timing of the image data with a different delay time for each component color so that the R, G, and B image data of the same pixel is simultaneously output on the frame image.
[0033]
The output terminal of the line scanner correction unit 122 is connected to the input terminal of the selector 132, and the image data output from the correction unit 122 is input to the selector 132. The input terminal of the selector 132 is also connected to the data output terminal of the input / output controller 134, from which file image data input from the outside is input to the selector 132. The output terminal of the selector 132 is connected to the input / output controller 134 and the data input terminals of the image processors 136A and 136B, respectively. The selector 132 can selectively output the input image data to each of the input / output controller 134 and the image processors 136A and 136B.
[0034]
The image processor unit 136A includes a memory controller 138, an image processor 140, and three frame memories 142A, 142B, 142C. Each of the frame memories 142A, 142B and 142C has a capacity capable of storing one frame of frame image data, and the image data input from the selector 132 is stored in any of the three frame memories 142. However, the memory controller 138 stores the image data in the frame memory 142 such that the data of each pixel of the input image data is stored in the storage area of the frame memory 142 in a fixed order. Control addresses.
[0035]
The image processor 140 takes in the image data stored in the frame memory 142, performs gradation conversion, color conversion, hypertone processing for compressing the gradation of an ultra-low frequency luminance component of the image, and enhances sharpness while suppressing graininess. Various image processing such as hyper sharpness processing is performed. The processing conditions of the image processing are automatically calculated by an auto setup engine 144 (described later), and the image processing is performed according to the calculated processing conditions. The image processor 140 is connected to the input / output controller 134, and the image data subjected to the image processing is temporarily stored in the frame memory 142 and then output to the input / output controller 134 at a predetermined timing. Note that the image processor unit 136B has the same configuration as the above-described image processor unit 136A, and a description thereof will be omitted.
[0036]
In the present embodiment, each frame image is read twice by the line CCD scanner 14 at different resolutions. In the first reading at a relatively low resolution (hereinafter, referred to as pre-scan), even when the density of the frame image is extremely low (for example, a negative image overexposed on a negative film), the saturation of the accumulated charge in the line CCD 116 is prevented. The frame image is read under the reading conditions determined so as not to occur (the light amounts of the R, G, and B wavelengths of light applied to the photographic film in each wavelength range, and the charge storage time of the CCD). Image data (pre-scan image data) obtained by the pre-scan is input from the selector 132 to the input / output controller 134, and further output to the auto setup engine 144 connected to the input / output controller 134.
[0037]
The auto setup engine 144 includes a CPU 146, a RAM 148 (for example, a DRAM), a ROM 150 (for example, a rewritable ROM), and an input / output port 152, which are connected to each other via a bus 154.
[0038]
The auto setup engine 144 reads a second relatively high resolution by the line CCD scanner 14 based on pre-scan image data of a plurality of frame images input from the input / output controller 134 (hereinafter referred to as fine scan). ), And calculates the processing conditions of the image processing for the image data (fine scan image data) obtained by (1), and outputs the calculated processing conditions to the image processor 140 of the image processor unit 136. In the calculation of the processing conditions of this image processing, it is determined whether or not there are a plurality of frame images capturing similar scenes based on the exposure amount at the time of capturing, the type of capturing light source and other characteristic amounts, and a plurality of frame images capturing similar scenes are determined. Are determined, the processing conditions for the image processing on the fine scan image data of these frame images are the same or similar.
[0039]
The optimum processing conditions for image processing also vary depending on whether the image data after image processing is used for recording an image on photographic paper in the laser printer unit 18 or output to the outside. Since the image processing unit 16 is provided with two image processor units 136A and 136B, for example, when the image data is used to record an image on photographic paper and is output to the outside, the auto setup engine 144 is used. Calculates the optimum processing conditions for each application, and outputs them to the image processor units 136A and 136B. Thus, the image processors 136A and 136B perform image processing on the same fine scan image data under different processing conditions.
[0040]
Further, the auto setup engine 144 performs image recording for defining the gray balance and the like when the laser printer unit 18 records an image on photographic paper based on the prescanned image data of the frame image input from the input / output controller 134. The parameters are calculated and output at the same time as recording image data (described later) is output to the laser printer unit 18. Further, the auto setup engine 144 calculates the processing conditions of the image processing for the file image data input from the outside in the same manner as described above.
[0041]
The input / output controller 134 is connected to the laser printer unit 18 via the I / F circuit 156. When the image data after the image processing is used for recording an image on photographic paper, the image data processed by the image processor 136 is transferred from the input / output controller 134 via the I / F circuit 156 to the recording image. The data is output to the laser printer unit 18 as data. The auto setup engine 144 is connected to a personal computer 158. When the image data after the image processing is output to the outside as an image file, the image data processed by the image processor 136 is output from the input / output controller 134 to the personal computer 158 via the auto setup engine 144. Is done.
[0042]
The personal computer 158 includes a CPU 160, a memory 162, a display 164, a keyboard 166 (see also FIG. 2), a mouse 177, a hard disk 168, a CD-ROM driver 170, a transport control unit 172, an expansion slot 174, and an image compression / decompression unit 176. Which are connected to each other via a bus 178.
[0043]
The transport controller 172 is connected to the film carrier 38 and controls the transport of the photographic film 102 by the film carrier 38. Although not shown, the film carrier 38 has a barcode sensor for reading the barcode 112 and a magnetic head for reading information recorded on the magnetic recording layer 116. Thus, the film ID recorded on the barcode 112 and the lens type recorded on the magnetic recording layer 116 can be read.
[0044]
As will be described later in detail, lens data (correction coefficient) for performing aberration correction according to the lens type is stored in the hard disk 168 as table data in advance.
[0045]
Further, a driver (not shown) for reading / writing data from / to a storage medium such as a memory card, and a communication control device for communicating with other information processing devices include a personal computer 158 via an expansion slot 174. Connected to. When image data for output to the outside is input from the input / output controller 134, the image data is output to the outside (the driver, the communication control device, or the like) as an image file via the expansion slot 174.
[0046]
When file image data is input from outside via the expansion slot 174, the input file image data is output to the input / output controller 134 via the auto setup engine 144. In this case, the input / output controller 134 outputs the input file image data to the selector 132.
[0047]
The image processing unit 16 outputs pre-scanned image data and the like to the personal computer 158, displays a frame image read by the line CCD scanner 14 on the display 164, and processes an image obtained by recording on a photographic paper. It is estimated and displayed on the display 164, and when an image correction or the like is instructed by the operator via the keyboard 166, this can be reflected in the processing conditions of the image processing.
[0048]
(About aberration correction processing)
The CPU 160 of the personal computer 158 is capable of correcting distortion (distortion) and chromatic aberration of magnification caused by lens aberration. These corrections are performed based on values calculated by a polynomial (correction formula) in which the correction ratio changes depending on the distance from the center position of the read image. That is, an appropriate pixel position of each pixel is determined based on the value calculated by the polynomial. The correction coefficients of the respective polynomials for performing the distortion correction and the lateral chromatic aberration correction differ for each lens type, and are stored in the hard disk 168 in advance.
[0049]
Further, the CPU 1 60, thereby making it possible to extract the main subject of the read image (for example, a human face). Here, if the face is blurred as shown in FIG. 6B by performing the distortion correction, the distortion can be corrected to such an extent that the face cannot be blurred. This is performed by changing the correction intensity of the aberration correction as shown in FIG. 7 according to the distance D from the end of the image to the end of the face (see FIG. 6B). That is, as shown in FIG. 7, when the distance D is large, the correction strength of the horizontal aberration correction is increased, and when the distance D is small, the correction strength is reduced. By doing so, it is possible to perform distortion correction to some extent without blurring the face.
[0050]
The change in the correction strength can be achieved by changing the correction coefficient of the above-described correction formula. The data of the correction coefficient corresponding to the distance D is stored in advance as table data on the hard disk 168, for example.
[0051]
Next, as an operation of the present embodiment, a control routine relating to reading of frame images and image processing executed by the CPU 160 of the personal computer 158 will be described with reference to the flowchart shown in FIG.
[0052]
When the operator inserts the APS film 102 into an insertion slot (not shown) of the film carrier 38 and gives a predetermined processing start instruction, the CPU 160 starts the control routine of FIG.
[0053]
In step 202 in FIG. 5, the lens type read by the magnetic head (not shown) of the film carrier 38 is read. Then, in step 204, a pre-scan is performed. That is, an image is read at a low resolution while transporting the APS film 102. Next, in step 206, fine scan is performed. That is, a reading condition is determined for each frame image based on the image read by the prescan, and the image is read at a high resolution.
[0054]
Next, a process of extracting a main subject (for example, a human face) in the image read in step 208 is performed. This is performed by obtaining, for each pixel, a density change value (edge strength) with respect to surrounding pixels, and tracing the contour of the face of the person based on the edge strength.
[0055]
Then, based on the contour data obtained in step 210, it is determined whether or not a face portion is blurred (image missing) when distortion correction is performed. In this method, distances D to the upper, lower, left, and right ends of the rectangular area 304 are respectively obtained from the coordinate values of the upper, lower, left, and right ends of the obtained contour data, and the face portion is shaded based on the distance D. It is determined whether or not.
[0056]
If it is determined that the face part cannot be blurred, a correction coefficient corresponding to the lens type is read from the hard disk 168 in step 212, and normal aberration correction processing is performed based on the correction coefficient. If it is determined that the face portion is blurred, a correction coefficient corresponding to the lens type read from the hard disk 168 and corresponding to the distance D is read in step 214, the correction strength is reduced based on the correction coefficient, and the face intensity is reduced. An aberration correction process is performed in a range where a part cannot be blurred. In the example shown in FIG. 6B, since the left end of the face is blurred, the aberration correction is performed by weakening the correction strength in the horizontal direction. When the aberration is corrected in this manner, the face portion does not need to be cut off as shown in FIG.
[0057]
Next, in step 216, the rectangular area 302 indicated by the dotted line shown in FIG. 6C is subjected to electronic scaling to enlarge it to a desired print size. Then, in step 218, the image data subjected to the aberration correction and the electronic scaling process is output to the laser printer unit 18.
[0058]
The laser printer unit 18 prints and prints on photographic paper based on the image data output from the image processing unit 16, and the processor unit 20 performs color development, bleach-fixing, washing, and drying. Thus, an image is formed on the printing paper.
As described above, even if a person's face is present at the end of the captured image, the face portion is automatically extracted and aberration correction is performed according to the face position. The printed image can be made natural.
[0059]
Further, when it is expected that the face portion is blurred by performing the aberration correction, the aberration correction may not be performed. In this case, step 216 may be executed without performing step 214 in FIG.
[0060]
The determination as to whether or not to correct the aberration may be made based on order information from a customer. For example, as the order information, priority is given to aberration correction (the face part may be shaded), priority is given to the face part falling within the print range without aberration correction, and the degree to which the face part cannot be shaken. The customer is allowed to select three types of designation in the lab, that is, perform aberration correction, and the processing is performed based on the order information designated by the customer. By doing so, it is possible to perform print processing according to the customer's preference.
[0061]
In the present embodiment, the case where the face of a person is prevented from being blurred has been described. However, the present invention is not limited to this, and the present invention can be applied to a characteristic shape that is easy to extract.
[0062]
Further, in the present embodiment, the case where the lens type is recorded in advance on the photographic film has been described as an example, but the lens data (correction coefficient) itself may be recorded on the photographic film.
[0063]
【The invention's effect】
As described above, according to the present invention, an image recorded on a photographic material is read, a main subject of the read image is extracted by an extracting unit, and the extracted main subject is shaken by performing aberration correction. When it is determined that the main subject is corrected, the aberration correction is performed to such an extent that the main subject cannot be shaken, so that there is an excellent effect that the main subject can be kept within the print range while appropriately correcting the image distortion. .
