Single Math

A mathematical operation is performed for each pixel of the current image.
The following eight mathematical operations are provided.
Operation
Invert
Multiply
Divide
Bitwise AND
Bitwise OR
Bitwise XOR
Add
Subtract
Here, pixel data does not mean the display brightness data (0 to 255) but the acquired 16
bit raw data (0 to 65535). Although an integer from 0 to 65535 can be entered for
Bitwise AND, OR, XOR, Add and Subtract, the result is converted to the range 0 to 255
for display.
If the resultant of the mathematical operation is negative, it is replaced with 0. If the
resultant of the mathematical operation exceeds 255, it is replaced with 255.
A mathematical operation is performed for each pixel, as follows.
【Example】
