SOC VGA DIGITAL IMAGE SENSOR
Table 9: Colorpipe Register Description (continued)
Bit 2:0
Specify color saturation attenuation at high luminance (linearly increasing attenuation from no attenuation
to monochrome at luminance of 224).
“000”—No attenuation.
“001”—Attenuation starts at luminance of 216.
“010”—Attenuation starts at luminance of 208.
“011”—Attenuation starts at luminance of 192.
“100”—Attenuation starts at luminance of 160.
“101”—Attenuation starts at luminance of 96.
R52:1—0x134 – Luma Offset (can be used to control brightness) (R/W)
Default
0x0010
Description Offset added to the luminance prior to output.
Bits 15:8
Y Offset in YCbCr mode.
Bits 7:0
Offset in RGB mode.
R53:1—0x135 – Luma Clip (R/W)
Default
0xF010
Description Clipping limits for output luminance.
Bits 15:8
Highest value of output luminance.
Bits 7:0
Lowest value of output luminance.
R58:1—0x13A – Output Format Control 2—Context A (R/W)
Default
0x0200
Description Output format control 2—context A.
Bit 14
Output processed Bayer data.
Bit 13
Debug flicker luma.
Bit 12
Reserved.
Bit 11
Enables embedding Rec. ITU-R BT.656 synchronization codes in the output data. See R155:1.
Bit 10
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.
Bit 9
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.
Bit 8
Enables RGB output.
0: Output YCbCr data.
1: Output RGB format data as defined by R58:1[7:6].
Bits 7:6
RGB output format:
“00”—16-bit RGB565.
“01”—15-bit RGB555.
“10”—12-bit RGB444x.
“11”—12-bit RGBx444.
Bits 5:4
Test Ramp output:
“00”—Off.
“01”—By column.
“10”—By row.
“11”—By frame.
Bit 3
Outputs RGB or YCbCr values are shifted 3 bits up. Use with R58:1[5:4] to test LCDs with low color depth.
Bit 2
Averages two nearby chrominance bytes. See R155:1.
