Embodiment Construction
[0022] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements. As above:
[0023] The present invention uses the set-top box as a signal generator to generate a standard video chromaticity signal, which is displayed through the TV, and then captures the chromaticity and other information of the video signal through the camera of the mobile phone, captures the data through analysis, and compares the signal generated by the set-top box The chrominance signal captured by the mobile phone camera constitutes a signal generation, result, result error, feedback, and adjustment control loop to calculate the actual performance error of the TV and the user's color preference, so that the TV can play Eye-pleasing color for professional-grade playback on regular TVs.

The invention discloses a method for adjusting color reduction capability of a television set through a set top box. The method comprises the following steps that an adjusting APP of a mobile phone is started firstly and communication between the mobile phone and the set top box is established, and a camera is started; a white video signal is transmitted to the set top box by the mobile phone; the white video signal is received by the set top box and transmitted to the television set to be displayed, the white color of the television set of the time is captured by the mobile phone, and first time of white balance adjustment is completed by the camera of the mobile phone; a mobile phone signal area and a set top box signal area are formed on the television set through the set top box; the white color of the mobile phone signal area is adjusted so that the white color of the mobile phone signal area is enabled to be consistent with the white color on the screen of the mobile phone as far as possible, the deviation value of the numerical values of the white color of the mobile phone area and the default white color of the set top box is calculated and the deviation value is enabled to be within the set range; and RGB color adjustment and calibration are performed after adjustment of the white color. Performance capacity of the television set can be fully explored so that the display color is enabled to be more vivid, clear and natural.
Description
technical field [0001] The invention relates to a method for adjusting / testing the color reproduction ability of a television set through a set-top box. Background technique [0002] As we all know, when people choose TVs in the supermarket, they find that the same program source, different models and brands of TVs, the colors and clarity of different TVs of the same model are not the same. [0003] After a TV is used for a period of time, the color gamut, backlight brightness, and chromaticity will all change. The aging of the TV will directly lead to a decline in the user's perception. At this time, it is necessary to reconfigure the video characteristics of high-definition output, so that the TV can regain its youth. [0004] Due to the deviation of the TV itself, due to the differences in backlight, LCD panel, various driving circuits, and video processing circuits, the video effects displayed by the same model are all kinds of strange. [0005] Each of the above probl...
