6.7.2 What is Gray Edge?
Gray Edge
This is a function to detect the pixels having more than a certain level of brightness based on gray value
of each pixel and to output the detect count and the coordinates in a gray image. This function detects up
to 256 edges within the area fulfilling the preset conditions. If the preset number of edges is output, it will
be judged "OK"; otherwise, it will be judged "NG". Up to 99 edges from the start point can be utilized for
calculation of the coordinate positions of the edges and be output to the external device.
