Description

A method for adjusting the color temperature effect of television images

technical field

The invention relates to the technical field of image color temperature processing, in particular to a method for users to independently adjust the color temperature effect of television images.

technical background

At present, the color temperature adjustments of TVs are all simple mode adjustments. There is no more detailed method that allows users to adjust the color temperature effect that is more suitable for them. At present, the simple color temperature mode adjustments generally only have several fixed effects of cool/warm/natural mode, not every user is satisfied with the color temperature mode.

Therefore, for TV, a product that plays an important role in people's daily life, finer adjustment of TV color temperature should also be essential. The fine adjustment referred to here is to obtain a more accurate color temperature adjustment result that is more suitable for human vision according to the specific environmental color temperature and specific race. Color temperature adjustment is actually white balance adjustment. White balance is a very abstract concept. The most popular understanding is to make the image formed by white still be white. If white is white, then the images of other scenes will be close to the color of human eyes. Visual habits. The process of adjusting the white balance is called white balance adjustment. In the case of higher and higher requirements on the color effect of TV sets, white balance has become an important indicator of the quality of color TV sets, and white balance adjustment is a key process in the production process of color TV sets. One, it is related to whether the color pole of the color TV can truly reproduce the original color of the object to be displayed. Before leaving the factory, the white balance of each color TV must be adjusted to the specified factory standard, which is what we usually call the factory default mode. With the globalization of the economy, the TV is such an indispensable product in daily life, the simple and fixed color temperature adjustment mode can no longer meet the needs.

We know that the color temperature of sunlight is constantly changing in daily life. It can be said that the color temperature of no two places will be exactly the same. Different regions, seasons, ground environments, weather, morning and evening, etc. will affect the color temperature. In addition, there are A large number of artificial light sources have different color temperatures.

For manufacturers, the sales area of their products is not limited to a certain country and region, but may be sold to any country or region in the world. We know the latitude and longitude of different countries and regions on the earth Different, the color temperature of the region is also different, and the eyes of people of different races around the world have slightly different recognition of colors, and people's eyes have slightly different recognition of colors at different times of the day. The current simple adjustment mode is bound to If the needs of people of different races in different regions cannot be fully satisfied, it becomes necessary for users to independently adjust the color temperature of the TV set.

Detailed ways

Fig. 1 and Fig. 2 are respectively the user management module flow chart adopting the method of the present invention TV set, and simple circuit block diagram, with reference to Fig. 1 and Fig. 2 describe in detail the embodiment of the present invention:

The method for the user to independently adjust the color temperature effect of the TV image in the present invention is to add a filter mode adjustment menu in the TV adjustment menu, the filter mode includes: fixed mode and user mode, and the fixed mode includes default/6500K 7300K 8500K 9300K five modes.

The method for adjusting the color temperature effect of the television image is specifically adjusted through the following steps:

Step 1: The system core judges whether to enter the switching filter mode state;

Step 2: Enter the switching filter mode to judge the state of the current filter mode;

Step 3: The user independently adjusts the color temperature parameters provided by the system according to the current state of the filter mode;

Step 4: The system processes and saves the display according to the user adjustment results. The method for adjusting the color temperature effect of television images is characterized in that said step 2 includes:

Step 21) If the state of the current filtering mode is the user state, enter the user management module;

Step 22) If the state of the current filter mode is fixed, continue to choose to enter the default mode or any mode of /6500K 7300K 8500K 9300K.

In said step 1, the core of the TV system adopts a UOC chip, and the UOC chip has a built-in user management module, which is used to realize the user's self-adjustment of the TV filter mode. The system judges whether to enter the switching filter mode by detecting whether there is a relevant key operation by the user. For example, the user presses the relevant key of the remote control, and the remote control sends out a corresponding infrared signal. At this time, the remote control receiving circuit receives the infrared signal and converts it into a digital signal and The digital signal is fed back to the UOC chip through the user management module, and the UOC chip responds to the user's operation according to the digital signal. The user can also operate through the TV's control keys, because the interactive function requires menu keys, volume +/- keys, channel + /- key, and this control key just has these keys and the function is the same as the related keys on the remote control, but this control key passes the AD conversion method, and the digital signal is fed back to the UOC chip through the user management module, and the UOC chip Respond to user operations based on digital signals.

In said step 21, select the user mode to enter the user management module, display the menu shown in Figure 5, each parameter in Figure 5 has a corresponding indicator bar, and the indicator bar in the flashing state indicates that the parameter can be adjusted in the current state , so that the user can operate the TV through the remote control button or the control button to adjust the parameter items of the filter mode (that is, the vertically arranged wavelength ranges in the menu 2500K 3300K 5600K 6500K 7300K 8500K 9300K 12000K 15000K) to meet their needs.

In the default mode, the menu shown in Figure 3 is displayed, and all parameters in the menu are 0. This mode is generally the TV factory setting. Figure 4 is a fixed mode menu diagram preset by the system. This mode is also The user can choose, but the selection range is relatively fixed, and it cannot satisfy the user's requirements for the color temperature effect to the greatest extent. In these two states, the UOC chip has a built-in WHITE-P. Adjust the value of the RGB register in a fixed state, so that the analog quantity output by the internal controller changes, realize the current adjustment of the R, G, and B three guns driving the picture tube, and adjust the color information to a certain fixed state. Meet the user's requirements for color preferences.

In the step 3, during the user adjustment process, the WHITE-P.ADJ module in the UOC chip will adjust the signal in real time according to the value of each parameter item adjusted by the user. While adjusting each parameter item in the menu, the user You can see the display effect of the image adjustment. When the user adjusts to a satisfactory state, stop the operation, and the UOC chip will save the final adjusted state of the user according to the signal sent by the user management module.

The BLKIN pin of the UOC chip will automatically detect the RGB color information of the current signal and feed it back to the built-in WHITE-P.ADJ module of the UOC chip. The WHITE-P.ADJ module will sample the signal according to the RGB color information of the current signal. , automatically correct the three primary colors of RGB, so as to achieve the best state of the color temperature required by the user. Moreover, the BLKIN pin will continuously detect the color information of the signal, correct the color according to the different information in real time, and adjust the value of the RGB register, so that the analog quantity output by the internal controller will change, and the R , G, B gun current adjustment, to achieve the purpose of adjusting the color temperature effect. Therefore, no matter how the color of the signal changes, the color state of the signal remains in a relatively stable state required by the user.

The method for the user to adjust the color temperature effect of the TV image independently in the present invention is more detailed than simply switching several color temperature modes in the past. The modes are also divided into five frequency spectrums of radiation (that is, each fixed filter mode) and the self-adjusting mode. In each filter mode in the menu, the value of the parameter item of each filter mode is also different. In the user mode Next, read out the values of each temperature and wavelength range adjusted by the user, and then calculate the system according to a certain algorithm, and display the frequency spectrum of the final color temperature. In this way, users can adjust the color temperature mode at will according to their own preferences. The application of the method of the present invention not only meets the needs of users in different regions and seasons for adjusting the color temperature of TV images, but also meets the needs of color blindness for TV color adjustment. To a certain extent, it will not allow manufacturers to affect the sales of products because the color temperature effect of TVs is not suitable for people of a certain ethnicity in a certain region.

Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Those skilled in the art can make corresponding changes or deformations according to the present invention without departing from the spirit and essence of the present invention. , but these corresponding changes or modifications should all belong to the protection scope of the appended claims of the present invention.
