(1) Comparative calculations between images

It is possible to run calculations on the differences between the images taken by camera 1 and camera

2, as well as on the differences between the current image and the already stored reference image.

There are two types of calculation: "subtraction" and the "absolute value of the differences."

Example of comparative calculations between images

Light level in image 1 (0 to 255) -

Light level in image 2 (0 to 255)

- Light level after calculation

However, a result less than 0 will

give a result of 0.
