Title: Image processing system
Inventor: MOROO JUN
IPC: G06T5/20
Filed: 1987-12-19
Abstract: PURPOSE:To prevent picture quality from deteriorating due to an increase in granulation which is the roughness of a screen by laying Laplacean emphasis selectively in cases of an edge and a noise as a means for removing the 'blurring' of an image. CONSTITUTION:Nine image elements of an image element matrix 1 are sent out to edge detection parts 21-24, which use masks to detect differences in image element value. When the maximum value among the differences by the masks is larger than a threshold value, contour emphasis is laid by a Laplacean arithmetic part 5 and when not, no emphasis is laid. Thus, the Laplacean emphasis is laid on isolated density variation due to a noise and density variation due to an edge selectively to preclude granulation deterioration which causes the image element to deteriorate.
