Edge detection/Emphasizing
process
Edge detection is the filter that detects an edge with
controlling noise by taking the difference of contracting
level of both sides of the original image in 4 directions-
left, right, top and bottom individually. This features
output of the clearer edge detected image.
Edge emphasis is the acumination filter which enables
adjustment of the acuminating level by setting a desired
weighting factor for the outline image made by edge
detection. An acuminated image can be displayed with
controlling noises. This is difficult only with the filter
process.
Note
In edge detection mode, the boundary of the CCD right
and left areas is rarely detected as the edge. This case
may be solved by changing the adjustment of the
automatic clamp control or turning off the automatic
clamp control temporarily.
