Example
Use this command to reset the camera:
Command Value

Hex 80h -
3.6 Adjusting Gain
Bit [6] of register 1 is the Video Gain control bit. When this bit=0 the video channel
gain=1x. When this bit =1, the video channel gain=4x.
Example
Use this command to set the gain to 4x:
Command Value
Binary 1000 0010 *1** ****
Hex 82h **h
Note: The register containing the Gain bit also controls other configuration data. All bits
must be set appropriately.
3.7 Adjusting User Offset
User offset is adjustable from -2047 to +2048 by a 12 bit value as an MS and LS byte. The
offset data is only written when the most-significant 8 bits are written to register 2.
Therefore, the lower 4 bits should be written first to register 3, followed by the upper 8
bits, which will cause the offset to be applied to the pixel output.
The pixel offset data is written as a 2’s compliment number. Therefore either positive or
negative offsets can be added to the pixel output to enhance the image contrast.
The offset value that is programmed effects the pixel offset by a ratio of about 8 to 5. So,
for that example, if an offset value of a positive 16 is entered to registers 2 and 3 the
resulting pixel data will be adjusted by a positive 10.
