5. Use the same method as shown in steps 3 and 4 to calculate the right side offset setting. For

our example, the result would be 72.

6. Convert the results to hexadecimal:

Left Side Offset Setting of 73 decimal = 0x0049

Right Side Offset Setting of 72 decimal = 0x0048

7. Use the left side offset and the right side offset binary commands to set the left side offset

and the right side offset to the calculated values.

After you use the commands to enter the calculated values, the camera will be operating at

an offset of 5 with respect to the reference camera and the left side and right side pixels will

be balanced.

3.5.5 Balancing Gain and Offset

Initially, it may not be obvious whether gray value differences between the left and right side of the

image result from gain imbalance and/or offset imbalance.

To balance gray value differences between the left and right side of the image addressing both,

gain imbalance and/or offset imbalance:

1. Prevent light from striking the camera’s sensor, e.g. by putting the cap that is shipped with

the camera on the lens mount.

2. Capture an image.

If there are gray value differences between the left and right side of the image adjust the offset

balance (see Section 3.5.4).

3. If a lens is not already in place, mount a lens on the camera and expose the camera’s sensor

to light.

4. Capture an image.

If there are gray value differences between the left and right side of the image adjust the gain

balance (see Section 3.5.2).

Offset and gain between the left and right side of the image are balanced.
