12.5.5. Offset Adjustment O Register (6 bits)

This register calibrates Voffset, the offset voltage from the output pin voltage Vref. The most significant bit

O5 is a sign bit. It can be adjusted in the positive direction and the negative direction if the most significant

bit is set to "H" and "L" respectively. A maximum value shall be 0.5 V. The amplitude is controlled by 5-bit

resolution.

12.5.6. Dark Pixel Line Output OB (1 bit)

When an image is output with the OB register being "L", the first line of the image frame becomes the

output signal from 128 dark pixels. Adjust the O register so that this dark pixel output (optical black) level
