Description
Technical field
The utility model relates to the television set debugging technical field, especially relates to a kind of white balance automatic adjusting system of television set.
Background technology
Television set becomes the recreation center of family life just gradually as one of closely bound up and indispensable household electronic products of a kind of and daily life.Television set needs the white balance circuit of television set is debugged in the machine system debug process, resets by the white balance parameter to television set, make the TV function reach predetermined colour temperature, allow the user during televiewing, the picture color of whole television set is normal, not colour cast.Tradition is to the debugging of television set white balance, normally adopt manually to adjust potentiometer or rely on remote controller to enter into factory's menu setting color data, but this debud mode not only debugging speed is extremely slow, and debugging poor effect.
The utility model content
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of white balance automatic adjusting system of television set is provided, and it is not only regulated the speed soon, the accuracy height, and also workable, can realize automation fully.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of white balance automatic adjusting system of television set comprises microcomputer, signal generator, television set, color analyzer and optic probe; This microcomputer comprises canonical parameter storage and output module, comparison module, parameter adjustment Executive Module, a RS232 serial ports, the 2nd RS232 serial ports and USB interface; The output of canonical parameter storage and output module is connected with the input of signal generator by a RS232 serial ports, and canonical parameter storage and output module are exported the chromaticity coordinates canonical parameter so that signal generator produces the test signal of standard to signal generator; The output of signal generator is connected with television set, signal generator to television set outputting standard test signal so that television set produces corresponding picture; The output of optic probe is connected with color analyzer, and optic probe picks up the chromaticity coordinates signal of TV set image and this chromaticity coordinates signal is defeated by color analyzer; Color analyzer is connected with comparison module by USB interface, and the chromaticity coordinates data after the chromaticity coordinates signal that color analyzer picks up optic probe is handled and will be handled are defeated by the comparison module of microcomputer; Storage of comparison module and canonical parameter and output module are connected, and comparison module extracts the chromaticity coordinates canonical parameter and compares with chromaticity coordinates data that color analyzer is defeated by from canonical parameter storage and output module; Comparison module is connected with the parameter adjustment Executive Module, and when the poor distance between chromaticity coordinates data and the chromaticity coordinates canonical parameter exceeded the scope of setting, the parameter adjustment Executive Module produces regulated the instruction of television set parameter control; The parameter adjustment Executive Module is connected with television set by the 2nd RS232 serial ports, and the parameter adjustment Executive Module is regulated the instruction of television set parameter control to television set output, and the adjustment of television set execution parameter also forms new picture according to the variation of parameter.
The white balance automatic adjusting system of a kind of television set of the present utility model after each equipment of system is all finished initialization and entered state to be adjusted, can begin to carry out the Automatic white balance adjustment.When carrying out the Automatic white balance adjustment, the order of adjusting the white balance of dark field signal after the white balance of system according to elder generation's adjustment bright field signal is finished the white balance adjustment of a colour temperature pattern of a passage, that is: the passage that will adjust of microcomputer elder generation initialization, colour temperature and adjustment parameter, and read the bright field chromaticity coordinates that the color analyzer optic probe measures, again bright field chromaticity coordinates and target color coordinates are compared and judge whether the bright field chromaticity coordinates reaches predetermined adjusting range, as reach predetermined adjusting range then system directly enter follow-up adjustment process, promptly carry out reading and relatively of details in a play not acted out on stage, but told through dialogues chromaticity coordinates; As do not reach predetermined adjusting range and then notify bright field white balance parameter that television system changes picture till meeting the demands.When system carries out the adjustment of details in a play not acted out on stage, but told through dialogues chromaticity coordinates, way is similar to the adjustment of bright field chromaticity coordinates, promptly read the details in a play not acted out on stage, but told through dialogues chromaticity coordinates earlier, again details in a play not acted out on stage, but told through dialogues chromaticity coordinates and target color coordinates are made comparisons, as the details in a play not acted out on stage, but told through dialogues chromaticity coordinates reach predetermined adjusting range then system directly enter follow-up adjustment process, promptly system reads bright, details in a play not acted out on stage, but told through dialogues chromaticity coordinates simultaneously; As do not reach predetermined adjusting range and then notify details in a play not acted out on stage, but told through dialogues white balance parameter that television system changes picture till meeting the demands.After bright field coordinate and details in a play not acted out on stage, but told through dialogues chromaticity coordinates are all adjusted, system reads simultaneously bright, details in a play not acted out on stage, but told through dialogues chromaticity coordinates, and once more bright, details in a play not acted out on stage, but told through dialogues chromaticity coordinates and target color coordinates are compared, all reach predetermined adjusting range as bright, details in a play not acted out on stage, but told through dialogues coordinate, then microcomputer notice system for TV set is preserved adjusted white balance parameter, otherwise readjusts bright field chromaticity coordinates and details in a play not acted out on stage, but told through dialogues chromaticity coordinates.Finish the white balance adjustment of a colour temperature pattern of a passage when system after, microcomputer reinforms system for TV set and signal generator, make its signal that switches different-colour pattern and different passages, and repeat the adjustment process of above-mentioned self-adjusting process with bright automatically, the dark white balance of finishing other colour temperature pattern, other passage.After the white balance adjustment of all passages, all colour temperature patterns is all finished, System Reports adjustment success, otherwise system will readjust bright field chromaticity coordinates and details in a play not acted out on stage, but told through dialogues chromaticity coordinates.
The beneficial effects of the utility model are, owing to adopt microcomputer, signal generator, television set, color analyzer and optic probe to form the white balance automatic adjusting system of television set, make this system not need to increase in addition instrument and equipment and can carry out the adjustment of television set white balance.This system can be completely achieved automation, and adjusts precision height, the piece of regulating the speed, good product consistency, thus full substitution the work of artificial adjustment white balance, and saved great amount of manpower and material resources for company.
Below in conjunction with drawings and Examples the utility model is described in further detail; But the white balance automatic adjusting system of a kind of television set of the present utility model is not limited to embodiment.
