Horizontal scale up/down flag for preview scaler (In 1:1 scale
[30]
ratio, this bit must be "1") 1: up, 0:down
Vertical scale up/down flag for preview scaler (In 1:1 scale ratio,
[29]
this bit must be "1") 1: up, 0:down
YCbCr Data Dynamic Range Selection for the Color Space
Conversion RGB to YCbCr (Preview path)
1 : Wide => Y/Cb/Cr (0 ~ 255) : Wide default
[28]
0 : Narrow => Y (16 ~ 235), Cb/Cr (16 ~ 240)
※ Recommend CSC range setting
CSCR2Y = CSCY2R (Wide=Wide or Narrow=Narrow)
YCbCr Data Dynamic Range Selection for the Color Space
Conversion YCbCr to RGB (Preview path)
[27]
1 : Wide => Y/Cb/Cr (0 ~ 255) : Wide default
0 : Narrow => Y (16 ~ 235), Cb/Cr (16 ~ 240)
FIFO Mode Enable. 1 for FIFO mode and 0 for DMA mode
FIFO mode output format is YCbCr4:4:4 or RGB24bit. its
[26]
selection depends on OutFormat register. OutFormat_Pr = RGB
→ RGB24bit , otherwise YCbCr4:4:4
Output scan method selection register only when FIFO mode
(LCDPathEn =1). 1 for Interlace scan and 0 for progressive scan.
[25] In DMA mode (LCDPathEn = 0), progressive scan is applied
whatever this value has.Interlace mode is allowed when MSDMA
input data & is not allowed when Camera processor input data
Horizontal scale ratio for preview main-scaler
Preview scaler start. This bit must be zero in preview scaler-
bypass mode.
[15]
1 : scaler start
0 : scaler stop
Input RGB format MSDMA for preview path dedicated
