2.2.3 Display Data Formats
OKI Semiconductor
The RGB format or YCbCr format can be selected as a display data format.
Because the data in a data buffer is in 16-bit YCbCr, 4:2:2 format, color space conversion is performed after
expanding into 24-bit, 4:4:4 format first.
Cb/Cr data is interpolated when expanding from 4:2:2 format to 4:4:4 format.
The color space conversion formula is in accordance with ITU-R Rec. BT-601.
