Abstract
The invention relates to the television technology, in particular to a picture color compensation method of television equipment. The invention discloses a picture color compensation method of television equipment, solving the problem that the television is easy to have color cast after being used for a long time in the prior art. The picture color compensation method comprises the steps of: a, selecting a television sample to be tested, recording color coordinates of a screen every a certain time in an accelerated ageing test; establishing a parameter table of congruent relationship of the color coordinates and the time; b, computing a color temperature according to the relationship of the color coordinates with the time change, and establishing a color temperature compensation parameter table; c, dynamically recording the starting-up running time after the television is started; and d, finding out the color temperature compensation parameter table according to the starting-up running time, judging whether the current color temperature parameter needs modifying or not, if so, adjusting the current color temperature to the color temperature compensation parameter of corresponding running time. The invention has the advantages of automatically compensating the picture color of the television equipment and improving the vision effect of the whole equipment, and is suitable for the television equipment.
Description
Technical field
The present invention relates to TV tech, relate to a kind of picture color compensation method of television equipment specifically.
Background technology
At general CRT, PDP, in the television systems such as LCD, use after one long period, whole image frame just has the situation of colour cast, the reason of colour cast mainly is because after the long use of television set process, differential declines has taken place in the performance of the luminescent material of each primary colours, the luminous efficiency of each primary colours has also produced different variations, cause the color generation colour cast of television image, the visual effect variation is as CRT, the luminous efficiency of employed fluorescent material can change in time among the PDP, colour temperature backlight among the LCD can be offset in time, causes color generation colour cast.
Summary of the invention
Technical problem to be solved by this invention is: occur the problem of colour cast after using for a long time at TV of the prior art easily, propose a kind of picture color compensation method of television equipment.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: the picture color compensation method of television equipment may further comprise the steps:
A. select test prototype, in accelerated aging test, write down the chromaticity coordinates of screen at regular intervals; Set up the parameter list of chromaticity coordinates and corresponding time relationship;
B. according to chromaticity coordinates in time variation relation calculate the colour temperature curve, and set up the color temperature compensating parameter list, the color temperature compensating parameter list comprises the color temperature parameters of start duration and corresponding duration;
C. dynamically recording start duration behind the television boot-strap;
D. search the color temperature compensating parameter list according to the start duration, judge whether current color temperature parameters needs to revise, be execution in step e then, otherwise return steps d;
E. current color temperature parameters is switched to the color temperature parameters of corresponding current duration in the color temperature compensating parameter list.
Among the described step a, the test prototype of selection possesses the television set of same process level for the N platform.
Described N is the numeral with statistical significance.
The invention has the beneficial effects as follows: compensate the picture color of television equipment automatically, improve the complete machine visual effect.
Embodiment
The present invention is directed to the problem that occurs colour cast after TV of the prior art uses for a long time easily, propose a kind of picture color compensation method of television equipment.Its guiding thought is: according to long-term observation, same process, the video screen of same material is after using for a long time, the decay of each primary colours luminous efficiency of screen is identical, promptly from the visual effect of complete machine, colour cast also is identical, the consistency that is to say the colour cast of television set is good, this just provides a thinking of correcting colour cast for us, for example adjusts the parameter of colour temperature, and the effect of the whole set of television of colour cast is adjusted on the desired parameter of design, visual effect from complete machine, use the situation of back and achromatization colour cast for a long time, prolonged the useful life of the high image quality of television set effectively, further promoted the value of television equipment.
Picture color compensation method among the present invention may further comprise the steps: a. selects test prototype, writes down the chromaticity coordinates of screen in accelerated aging test at regular intervals; Set up the parameter list of chromaticity coordinates and corresponding time relationship, in order to test as far as possible accurately, can select the N platform to possess the tv test of same process, same material, N has the meaning on the statistics, select 5 in 100 television sets of for example same batch and test, select 50 in 1000 television sets of perhaps same batch and test;
B. according to chromaticity coordinates in time variation relation calculate the colour temperature curve, and set up the color temperature compensating parameter list, the color temperature compensating parameter list comprises the color temperature parameters of start duration and corresponding duration;
C. dynamically recording start duration behind television boot-strap;
D. search the color temperature compensating parameter list according to the start duration, judge whether current color temperature parameters needs to revise, be execution in step e then, otherwise return steps d;
E. current color temperature parameters is switched to the color temperature parameters of corresponding current duration in the color temperature compensating parameter list.
Because it is veryer long that colour temperature changes, therefore only need starts or be provided with under open state and when starting this functional switch and get final product at complete machine.In the present invention, test getting final product when the mensuration of chromaticity coordinates can be with ageing test, need not the use value that other costs, practicality are big, can further promote television equipment.
