Hello Hooman, By full scale value you mean the max. value at 16 bit data i.e. 65535 or the max. amplitude value from the sensor (3.3V). Right now I get zero values on black line but if set offset 5%of the full scale value then it would be 3276 and the 95% of the full value is 62258. So these two values are the range of my digital signals? In my sensor the first 38 pixels are inactive pixels but its not mention in the datasheet that they are black pixels but they give an output around 1V as you can see in the scope image where I marked 1. I have set this as a VCLP reference. (0.35Vin). Is it correct or should I set the VCLP at position 2. Because you told me to set the minimum output value as a VCLP value.
