Scaler bypass. In this case, ImgCptEn_SC should be 0, but
ImgCptEn should be 1.
Generally this mode uses large image size upper scaler
maximum size. (This mode is intended to capture JPEG input
image for DSC application).
[31]
In this case, input pixel buffering depends on only input
FIFOs, therefore system bus should not be busy in this mode.
ScalerBypass has some restriction. Size scaling, color space
conversion, Input DMA mode and any RGB format are not
allowed. If input format is YCbCr4:2:2, output format should
be YCbCr4:2:2 or YCbCr4:2:0
Horizontal scale up/down flag for scaler (In 1:1 scale ratio,
[30]
this bit should be "1") 1: up, 0:down
Vertical scale up/down flag for scaler (In 1:1 scale ratio, this
[29]
bit should be "1") 1: up, 0:down
YCbCr Data Dynamic Range Selection for the Color Space
