Table 2. SIF Registers Descriptions (continued)
Bit Description
Default
0x28 ANALOG GAIN CONTROL
[7:4] Analog gain settings for low light operation
0x00
0x00: 1x gain (default)
0x81: 2x gain
0x92: 3x gain
0xA3: 4x gain
Others: Reserved
0x29 through 0x3A
Reserved.
0x3B ROW NOISE FILTER AND DARK LEVEL COMPENSATION
[7]: Enable frame based auto dark correction
0x00
1: enable
0: disable
[6]: Enable row noise filter
1: enable
0: disable
Note: bit[7] should be set to ‘0’ if row noise filter is
enabled.
[5]: Auto enable row noise filter
1: Automatic activation mode
0: Manual activation mode
Setting this bit will turn on row noise filter automatically
when analog sensor gain is applied
[2:0]: Frame based auto dark correction hysteresis control
0: 4 frames
1: 8 frames
2: 16 frames
0x3C ROW NOISE FILTER IMAGE OFFSET
Image offset value when row noise filter is enabled.
0x0a
0x3D FRAME BASED DARK COMPENSATION IMAGE OFFSET
Image offset value for frame based dark level compensation. 0x00
0x3E through 0x3F
Reserved.
0x40 DARK OFFSET SUBTRAHEND (LSB)
0x41 DARK OFFSET SUBTRAHEND (MSB)
[9:0] When auto dark correction is disabled, serve as the
0x0000
subtrahend for dark correction
0x42 HIGH DEAD PIXEL THRESHOLD (LSB)
0x43 HIGH DEAD PIXEL THRESHOLD (MSB)
[9:0] Apply dead pixel removal algorithm only to pixels
