- the number of bytes after compression processing of the input image is estimated based on the high-frequency component and low-frequency component in the horizontal direction and the high-frequency component and low-frequency component in the vertical direction. Based on the number of bytes, a compression rate for compressing the input image by one compression process is calculated (see Patent Document 1).

- CPU Central Processing Unit
- LCD interface 109 for display control.
- the CPU 108 gives an operation request to the image processing circuit 106, and receives a completion notification, frequency information of the input image, and camera shake information from the image processing circuit 106. Further, the CPU 108 gives an operation request and a compression rate to the compression / decompression processing circuit 107 and receives a completion notification from the compression / decompression processing circuit 107.
- FIG. 2 shows an example of designation of the detection block position for acquiring frequency information and the camera shake block position for acquiring camera shake information in the input image of the imaging device 111 of FIG.
- the position of the block 3 is determined as a detection block and a camera shake block by designating the X1, X2, Y1, and Y2 coordinates in FIG.
- the positions of the other blocks 1, 2, 4 to 10 are also determined by specifying the two coordinates of the horizontal coordinates X1 to X8 and the two coordinates of the vertical coordinates Y1 to Y8 in the same manner.
- FIG. 3 is a flowchart illustrating an operation in which the CPU 108 acquires frequency information of an input image in the imaging apparatus 111 in FIG. If the detection block position is not designated at S301 in FIG. 3, the CPU 108 designates the detection block position to the detection processing circuit 103 at S304 as shown in FIG. The detection processing circuit 103 detects the input image in units of designated detection blocks. The CPU 108 acquires the frequency information detected by the detection processing circuit 103 from the image processing circuit 106 in the loop of S302 and S303. However, the frequency information of the input image may be acquired in units of frames.
- FIG. 4 is a flowchart showing an operation in which the CPU 108 acquires camera shake information in the imaging apparatus 111 of FIG. If the camera shake block position is not designated at S401 in FIG. 4, the CPU 108 designates the camera shake block position to the electronic camera shake processing circuit 104 at S404 as shown in FIG.
- the electronic camera shake processing circuit 104 detects camera shake information (motion amount) of the input image in units of designated camera shake blocks.
- the CPU 108 acquires the camera shake information detected by the electronic camera shake processing circuit 104 from the image processing circuit 106 in the loop of S402 and S403.
- camera shake information may be acquired in units of image frames.
- FIG. 5 is a flowchart showing an image compression rate control method by the CPU 108 in FIG.
- S501 “threshold 1” to be compared with the acquired frequency information is set.
- S502 “threshold value 2” to be compared with the acquired camera shake information is set.
- S503 the average value A1 of the frequency information of the detection blocks 1 to 10 in FIG. 2 is calculated.
- S504 the average value A2 of the camera shake information of the camera shake blocks 1 to 10 in FIG. 2 is calculated.
- the threshold value 1 set in S501 is compared with the average value A1 of the frequency information calculated in S503. If the average value A1 of the frequency information is larger than the threshold value 1, it is determined that there are many high-frequency components in the input image. In step S506, the image compression rate is increased. If the average value A1 of the frequency information is smaller than the threshold value 1, it is determined that there are many low frequency components in the input image, and the compression rate of the image is lowered in S509. In other words, taking advantage of the human visual characteristics of being “insensitive” to high-frequency components and “sensitive” to low-frequency components, the compression rate is increased when there are many high-frequency components. When there is a large amount, the compression rate is lowered so as to improve the coding efficiency so that the image quality is not deteriorated.
- step S507 the threshold value 2 set in step S502 is compared with the average value A2 of camera shake information calculated in step S504. If the average value A2 of camera shake information is greater than the threshold value 2, it is determined that the input image is moving. In step S508, the image compression rate is increased. If the average value A2 of the camera shake information is smaller than the threshold value 2, it is determined that the input image is not moving, and the image compression rate is lowered in S510. That is, when the input image is moving, the image becomes smooth by increasing the compression rate.
- the compression rate instructed from the CPU 108 to the compression / decompression processing circuit 107 is set.
- the compression / decompression processing circuit 107 compresses the input image according to the compression rate instructed from the CPU 108 and stores the result in the memory 105.

- S601 “threshold value 1” to be compared with the acquired frequency information is set.
- S602 “threshold 2” to be compared with the acquired camera shake information is set.
- step S603 a difference value D1 between the maximum value and the minimum value of the frequency information for each detection block is calculated.
- a difference value D2 between the maximum value and the minimum value of the camera shake information for each camera shake block is calculated.
- the threshold value 1 set in S601 is compared with the difference value D1 between the maximum value and the minimum value of the frequency information calculated in S603, and the difference value D1 between the maximum value and the minimum value of the frequency information is the threshold value 1. If it is greater than the threshold value, it is determined that there are many high-frequency components in the input image, and the compression rate of the image is increased in S606. If the difference value D1 between the maximum value and the minimum value of the frequency information is smaller than the threshold value 1, it is determined that there are many low frequency components in the input image, and the compression rate of the image is lowered in S609.
- the threshold value 2 set in S602 is compared with the difference value D2 between the maximum value and the minimum value of the camera shake information calculated in S604, and the difference value D2 between the maximum value and the minimum value of the camera shake information is the threshold value. If it is greater than 2, it is determined that the input image is moving, and the compression rate of the image is increased in S608. If the difference value D2 between the maximum value and the minimum value of the camera shake information is smaller than the threshold value 2, it is determined that the input image is not moving, and the compression rate of the image is decreased in S610.
- the compression rate instructed from the CPU 108 to the compression / decompression processing circuit 107 is set.
- the compression / decompression processing circuit 107 compresses the input image according to the compression rate instructed from the CPU 108 and stores the result in the memory 105.
