SCENARIO 4

Coarse Adjust Calibration enabled for 1

st line, Fine Adjust Calibration enabled every line with the Fine

Adjust result accumulated throughout frame and used at start of next frame. This scenario is

intended to be used with a sequence of multiple frames, the first frame being used as a calibration

frame. This is good for use with sensors containing very few black-pixels as the black-level offset can

be calculated over an entire frame and there will be no line-by-line variation in the black-level from the

BLC circuitry. Table 9 shows which registers are required for this scenario with example settings.
