Depending on end, adjust through multiple step-length, by the depositor of the suitable RGB-GAIN value for finally obtaining write intelligent television end；
Step 5, intelligent television end preserve the RGB-GAIN value to EEPROM, while Flag to be stored in EEPROM in the lump
In, and TRUE is set to, simultaneously refreshed UI RGB-GAIN shows, storage is finished accordingly is pointed out；
The white balance parameter uses part, comprises the following steps：
The RGB-GAIN value of each source and passage is obtained when step 6, intelligent television end start from data base, as the overall situation
Variable；
Step 7, intelligent television end obtain current Flag from EEPROM, and judge whether Flag is TURE, if then
Step 8 is entered, need not otherwise do white balance debugging；
RGB-GAIN value under RGB-GAIN value in EEPROM and mode standard is compared by step 8, intelligent television end,
Deviant being obtained, deviant is changed on other sources and contextual model, depositor is write as new RGB-GAIN value.
Specifically, in step 1, the colour temperature instrument is the colour temperature instrument of model CA-310.
Further, in step 1, the signal generator exports HDMI signal, and the form of the HDMI signal is 1080i
The complete white field signal of 60Hz and 80%Level brightness.
Specifically, in step 2, the parameter of the UART serial ports includes configuration using HDMI UART serial communication.
Further, in step 4, the data that colour temperature instrument is gathered are converted to RGB-GAIN value and pass through by the computer
In UART serial ports write intelligent television end, computer is that the chromaticity coordinates of colour temperature instrument collection is converted to RGB-GAIN as requested
Value.
Specifically, in step 5, described accordingly prompt for show white balance debugging success.
The invention has the beneficial effects as follows, in the present invention program, by above-mentioned intelligent television end AWB debugging side
Method, it is possible to resolve the inconsistent problem of subjective effect that intelligent television liquid crystal display screen colour temperature difference is caused, improves image quality effect, improves effect
Rate simultaneously reduces production cost.
Specific embodiment
With reference to embodiment, technical scheme is described in detail.
Intelligent television end AWB adjustment method of the present invention includes white balance parameter fetching portion and white balance
Parameter uses part, and wherein, white balance parameter fetching portion is：First intelligent television end is connected with colour temperature instrument, its HDMI end
Mouth is connected with signal generator, and its UART serial ports is connected with computer, and computer is connected with colour temperature instrument, in intelligent television end
The parameter of UART serial ports after startup, is set, starts an independent thread RGB-GAIN data of UART serial ports are obtained, so
Intelligent television end sets up communication with computer by UART serial ports afterwards, and the data of colour temperature instrument collection are converted to RGB- by computer again
GAIN value writes intelligent television end by UART serial ports, adjusts through multiple step-length, by the suitable RGB-GAIN for finally obtaining
In the depositor of value write intelligent television end, last intelligent television end preserves the RGB-GAIN value to EEPROM, while will
Flag is stored in EEPROM in the lump, and is set to TRUE, and simultaneously refreshed UI RGB-GAIN shows, storage is finished and accordingly carried
Show；White balance parameter using part be：The RGB- of each source and passage is obtained when intelligent television end is started shooting first from data base
GAIN value, used as global variable, intelligent television end obtains current Flag again from EEPROM, and judges that whether Flag is
TURE, if not need not then do white balance debugging, if then intelligent television end is by the RGB-GAIN value in EEPROM and standard
Under pattern, RGB-GAIN value is compared, and obtains deviant, and deviant is changed on other sources and contextual model, as new
RGB-GAIN value writes depositor.
