I have some questions about more details of I2P conversion of ADV7282A-M.
I had asked similar question about this on the following Engineer Zone thread:
[ADV7282A-M] More details of the I2P interpolation.
Question and your answer:
Does it mean linear interpolation? (Does it mean that line2 is interpolated by linear?)
Is it the way to generate line 2 from average of line 1 and line 3?
YES, linear interpolation will generate an new scan line between two input scan lines, & You can get the more details of linear interpolation in the "video-demy5.pdf" .
outn = (inn–1 + inn+1) / 2
But it seems that the I2P interpolation is not only "outn = (inn–1 + inn+1) / 2".
I summarized the questions to an attached file "ADV7282A_M_I2P_Conversion_Questions.xlsx".
Please refer it.
