Setting Digital Offset

Purpose:

Sets the digital offset. Digital offset is set to zero when you
perform FPN correction (

88H

ccf

command). If you are unable to

perform FPN correction, you can partially remove FPN by
adjusting the digital offset.

Syntax:

sdo t i

Syntax Elements:

Tap selection. Allowable range is

depending on

camera model, or

for all taps.

Subtracted offset value in a range from

2048

where

FPN Coefficient=

(12 bit LSB Justified)

Notes:

•

When subtracting a digital value from the digital video
signal, the output can no longer reach its maximum unless
you apply digital gain using the

89H

ssg

command. See the

previous section for details on the

90H

ssg

command.

Related Commands:

91H
