CVB Arithmetic is the tool for mix of images. It performs arithmetic and logical calculation among various images. It performs calculations among images such as addition, subtraction, multiplication, division, AND, OR, XOR in pixel units.
CVB Arithmetic enables flexible handling about overflow in calculation range.(the result of addition of 2 different images with each 8 bit can be earned 8bit and 16bit)
MMX technique improves the speed comparing the original tools.

Addition, subtraction, logical operations (AND, OR, XOR)
Multiplication, division
Reduction of the bit depth of the image from 16 to 8 bits
LUT transformation
