ADV7842 : Strange behavior on video adjustments

Hi ,

 

I have some problems to adjust the contrast, brightness, saturation and hue in SDP mode (composite video source) with the following registers 0x13 0x14 0x15 0x16 0x17.

When I varied the video adjustments (contrast, brightness, ...)  I was seeing unexpected changes in the colour space.

Could you send me the procedure to use?
By mistake I set the 0x3 value in the 0xe0 register in SDP map and it improves the luminance, could you send me the doc of this register?


Thanks & Best Regards

 

Khalid
