Using the reference image area setting in the gray scale search mode, the area of maximum contrast
can be identified automatically in the captured image.
- While moving the selected reference image area within the specified search area on the captured
image one pixel at a time, the IV-C35M determines the density in each area in the reference
image, and automatically picks the area with the largest difference.
