Registers
Reg0x60,
Reg0x61,
Reg0x63,
Reg0x64
These registers contain the 9-bit signed black level calibration values. In normal operation, these
values are calculated at the beginning of each frame. However, if Reg0x62, bit 0 is set to “1,” these
registers can be written to, overriding the automatic black level calculation. This feature can be
used in conjunction with readout of the black rows (Reg0x20, bit 11) if the user would like to use
an external black level calibration circuit. The offset correction voltage is generated according to
the following formula:
Offset Correction Voltage = (9-bit signed
calibration value, -256 to 255) x (2mV x Enable bit)
two’s complement, if bit 8 = 1, Offset = bits [0:7] - 256
ADC input voltage = Pixel Output Voltage x Analog Gain - Offset Correction Voltage
