Description
Obtain average light level of the image in the area detected using the gray search.
Calculate the difference of the absolute values from the image detected using the
gray search and the reference image. The result is light level difference. By
obtaining this value, you can get an idea of the total change in light level.
Total light level difference = S (Ni — Nt)
Ni : Light level of the captured image (contraction 3)
Nt : Light level of the reference image (contraction 3)
