不好意思,Spec关于这部分的内容比较散,我先只贴关于Scaler-bypass的设置说明部分。
最主要的关于Scaler-bypass的设置内容是:
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
4:2:0,4:2:2 & interleave 4:2:2
