Re: 16bit 640x480 OV7725 read?

I see. Wouldn't you agree that this text on the product web page is, at least, very misleading, since it says nothing about further compression, or inability of onboard processing? "The OV7725 image sensor is capable of taking 640x480 8-bit Grayscale images or 640x480 16-bit RGB565 images at 60 FPS ...

So, from OpenMV docs, it states: - Bayer can be used for capturing, not processing - All algorithms runs faster on grayscale - All al...

Is this possible within the current version (mine is 1.9.0) of OpenMV IDE ? Speed is not the top priority, but th...
