ScalerBypass_Co
[31]
Codec scaler bypass. In this case, ImgCptEn_CoSC must be 0,
but ImgCptEn must be 1.
Generally this mode uses large image size upper scaler
maximum size. Therefore it is not recommended to capturing
preview image. (Recommend, ImgCptEn_PrSC must be 0). This
mode is intended to capture JPEG input image for DSC
application).
In this case, input pixel buffering depends on only input FIFOs,
so system bus must not be busy in this mode.
ScalerBypass has some restriction. it is not allowed size scaling,
color space conversion, rotator and MSDMA memory input
image. so, Input / output format is allowed YCbCr non-interleave
