Colorpipe Register Description (continued)
S pecify color saturation attenuation at high luminance (linearly increasing attenuation from no attenuation
to monochrome at luminance of 224).
“000”
“001”
“010”
“011”
“100”
“101”
0x0010
Offset added to the luminance prior to output.
Y Offset in YCbCr mode.
Offset in RGB mode.
0xF010
Clipping limits for output luminance.
Highest value of output luminance.
Lowest value of output luminance.
0x0200
Output format control 2—context A.
Output processed Bayer data.
Debug flicker luma.
Reserved.
Enables embedding Rec. ITU-R BT.656 synchronization codes in the output data. See R155:1.
Entire image processing is bypassed and raw bayer is output directly.
In YCbCr or RGB mode:
0: Normal operation, sensor core data flows through IFP.
1: Bypass IFP and output Imager data directly (full 10 bits). The image data still passes through the camera
interface FIFO and the 10 bits are formatted to two output bytes through the camera interface; i.e., 8 + 2.
Data rate is effectively the same as default 16-bit /per pixel modes. Auto exposure/AWB, etc., still function
and control the sensor, though they are assuming some gain/correction through the colorpipe. See R155:1.
Inverts output pixel clock. By default, this bit it asserted and data is launched off the falling edge of PIXCLK
for capture by the receiver on the rising edge. See R155:1.
Enables RGB output.
0: Output YCbCr data.
1: Output RGB format data as defined by R58:1[7:6].
RGB output format:
“00”
“01”
“10”
“11”
Test Ramp output:
“00”
“01”
“10”
“11”
Outputs RGB or YCbCr values are shifted 3 bits up. Use with R58:1[5:4] to test LCDs with low color depth.
Averages two nearby chrominance bytes. See R155:1.
