The
offset adjustment in analog space prior to the ADC. The
6-bit register uses its MSB to indicate positive or nega-
tive offset. Each bit value changes the offset value by 4
5.4 Post ADC Block
The post ADC block contains the bad-pixel replacement
registers and a general output control register.
The
Black Pixel Threshold Register; Table
set the thresholds for white and black pixel replace-
ments. The MSBs on the
ter
threshold value between 0
es the sensor to replace any pixel value at or below the
threshold by the average value of the neighboring same
color pixels. Similarly the MSBs on the
Threshold Register
replacement threshold level between 768
be set. Again; as in the dark thresholding, if the sensor
encounters any pixel value that exceeds the set thresh-
old, it will replace it with the average value of the neigh-
boring same color pixels.

Description
LSB code levels hence giving an offset range of +/-124
LSB. As an example, to program an offset of +92 LSB,
the binary representation of +23
be loaded.
Care should be taken in assigning these thresholds.
This function performs an averaging effect on the im-
age, therefore, the greater the code distance the thresh-
olds move from the voltage rail, the more averaging
occurs between pixels.
