Thanks for your response. Going through the Datasheet & omap3isp code. what i understand is The code enables the H3A engine for AF, AE and AWB. Now, the H3A produces co-efficients which need to be used for achieving actual AF, AE & AWB. Now, I could not find any references where these co-efficents are used to do AF, AE & AWB. My specific question is now if i need to do AF - Do you know any formula or algorithm which can make use of these co-coefficients and control the sensor motor. Similarly - How AWB is done with the help of these co-efficients when AWB is enabled? Correct me if i am wrong. Thanks.
