Filter - Sony XCL-5000 Technical Manual

Filter

Executes matrix operation of 3x3 pixels to add various
processes to the picture. In MODE 1, 9 filter factors can
be set to the range from –10.000 to +10.000 in 0.001
x Setting example
(a) Secondary differentiation (Laplacian) filter
of 8 proximity
This filter detects an edge-a point where the contrast is
changed like the outline of the object in the picture.
(b) Picture acumination filter
A point where the contrast is changed, like an edge, is
emphasized by subtracting the secondary
differentiation. In the following filter, the Laplacian
filter of 8 proximity is multiplied by weighting factor
0.111, and then subtracting from the original image. It
emphasizes the edge by controlling the acumination
level.

interval. In MODE 2, the regulation filter like Laplacian
can be set easily.
When MODE 1 is selected, the automatic correction
function (automatic clamp control) cannot be set to On.
