I'm using a DM6446 card to take images from an external camera and create some JPEGs. The system works great but my problem is with the different resolutions within the codec. At the normal 720x540 resolution it gives me the complete field of view, but when I drop down to say 320x240 instead of using the full field of view and only using every other pixel it uses all the pixels in the central 320x240 box of the frame. How do I get the sensor to use the entire field of view when capturing at different resolutions?
If that's not possible and instead I'll have to do the interpolation myself, what is the most efficient method of copying every other pixel from the input frame to another buffer that I can then use for the JPEG compression?
