[background technology]
LCD TV is before dispatching from the factory, and production firm generally can adjust a kind of pattern of best image quality at the screen body characteristics of TV liquid crystal display screen and image quality processing IC for the user in the design link, and this pattern is commonly referred to " standard " pattern.Yet, in view of the processing path and the feature of different passages has difference, the adjusting data of different passages are inconsistent, regulating the parameter that is applied to the image quality processing IC of coming out below each passage may be different, be embodied in and promptly show as (the brightness of image quality data on client's menu, contrast, parameters such as tone) difference.Along with the consumer is more and more higher to the requirement of TV image quality demonstration aspect, this kind situation can not satisfy consumer's requirement.So need a kind of scheme of exploitation, with the consistency of the adjusting data that guarantee different passages.
[summary of the invention]
For addressing the above problem, main purpose of the present invention is to provide a kind of image quality on television adjusting device and its implementation, regulates the difference of data to avoid under the standard picture pattern image quality under the different passages, realizes striding the consistency of each passage image quality of passages regulate.
For achieving the above object, technical scheme of the present invention is:
A kind of image quality on television adjusting device, comprise the television signal receiver module that receives digital catv signal or receiving satellite word TV signal from the Cable Network network, connect described television signal receiver module, to be used for the digital television signal that receives is carried out the decoder of decoding processing, be connected to the multi-channel A V signal switch module of decoder, and the ADC module that connects component and rgb signal, wherein, the output of decoder and ADC module is connected with channel switching module, the input of channel switching module also is connected with TV passage image quality and regulates IC data memory module and other passage image quality adjusting data offset memory module, and the output of channel switching module is connected to display module.
A kind of control method of image quality on television comprises the steps:
The image quality that TV passage image quality is regulated under the data memory module storage TV passage is regulated data;
The image quality that other passage image quality adjusting data offset memory modules are stored under other passage is regulated data offset;
Channel switching module is carried out the instruction of user's switching channel, calling module TV passage image quality is regulated the data that store in data memory module and other passage image quality adjusting data offset memory module and is carried out the parameter adjustment on backstage, thereby realizes striding the consistency of each passage image quality of passages regulate.
Compared to prior art, the present invention is written into corresponding image quality side-play amount in the passage handoff procedure of television set, avoids under the standard picture pattern image quality under the different passages to regulate the difference of data, realizes striding the consistency of each passage image quality of passages regulate.
[description of drawings]
Fig. 1 is the theory diagram of image quality on television adjusting device of the present invention.
[embodiment]
See also shown in Figure 1ly, a kind of image quality on television adjusting device of the present invention comprises television signal receiver module, connects the decoder of television signal receiver module, is connected to the multi-channel A V signal switch module of decoder and the ADC module that connects component and rgb signal.Wherein, the output of decoder and the ADC module input that is connected to channel switching module, channel switching module is connected with also that TV passage image quality regulates that IC data memory module and other passage image quality are regulated the data offset memory module and the output of channel switching module is connected to display module.Described television signal receiver module is used for receiving digital catv signal or receiving satellite word TV signal from the Cable Network network; The input of described decoder connects described television signal receiver module, to be used for that the digital television signal that receives is carried out decoding processing.Wherein, TV passage image quality is regulated data memory module and other passage image quality and is regulated data offset memory modules and carry out backstage (mainly being software systems) for the module channels handover module when the switching channel and call basic or the offset data use.
Channel switching module comprises the signal input part part, switch sections, and importation, when system carries out the passage switching, by the software control relevant register switch opens is arrived corresponding passage input, input signal and output are carried out gating, by system corresponding passage is carried out the setting of initialization data then.
Channel switching module is used for carrying out the backstage when switching channel side-play amount is written into, be controlled at and be written into the side-play amount of each passage in the passage handoff procedure with respect to the TV main channel, each passage is cured to corresponding software among the EEPROM of system with respect to the side-play amount of TV passage by the software engineer, carrying out passage when conversion, judging and control being written into of side-play amount by channel switching module.Television set is finished after the gamma correction, and contrast model machine subchannel carries out the adjusting of image quality data to reach optimum state.Wherein, the image quality data comprise brightness, contrast, color harmony acutance.At first regulate the data of TV passage, record is also preserved, regulate by the same manner and corresponding data record is preserved at other passages afterwards, calculate the difference of each passage and TV passage, to hand to the software engineer with series data afterwards, these data be write among the EEPROM by the software engineer.
In the actual application, the RF signal amplifies after by television signal receiver module, and carries out light tone by decoder and separate the back as one road input signal admission passage handover module; And multi-channel A V signal switch module carries out one road gating earlier, enters decoder and carries out entering channel switching module as one road input signal after light tone is separated.The RGB/ component signal carries out digital-to-analogue conversion by the ADC module, the passage switching command of channel switching module responding system, and judge according to passage whether decision is regulated data offset modules with other passage image quality and be written into, if TV passage, then channel switching module is only controlled and is written into image quality and regulates data and get final product, if other signals, then need to be written into the side-play amount that image quality is regulated data, the processing through subsequent module after the signal output that channel switching module control is selected shows to display module.Channel switching module is when carrying out the instruction of user's switching channel, calling module TV passage image quality is regulated the data that store in data memory module and other passage image quality adjusting data offset memory module and is carried out the parameter adjustment on backstage, thereby realizes striding the consistency of each passage image quality of passages regulate.
Most preferred embodiment described above only is that the present invention is set forth and illustrates, but is not limited to disclosed any concrete form, and it is possible carrying out many modifications and variations.
