摘要： In an edge correcting circuit of an image to be represented by a digitized image signal, a high-frequency signal extracting circuit (5) extracts a high-frequency signal of the image by calculation based on a signal of a target pixel, a signal of a pixel shifted from the target pixel by m (m being an integer not smaller than 2) pixels in the right or lower direction, and a signal of a pixel shifted from the target pixel by m pixels in the left or upper direction, an amplitude-restricting signal generator (6) determines an amplitude-restricting signal (Si) based on a minimum value or a maximum value of an absolute value of a difference between the signal of the target pixel and a signal of a pixel shifted from the target pixel by n (n being an integer not smaller than 1 and smaller than m) pixels in the right or lower direction, and an absolute value of a difference between the signal of the target pixel and a signal of a pixel shifted from the target pixel by n pixels in the left or upper direction, an amplitude restricting circuit (7) restricts the output of the high-frequency extracting circuit (5) to the output of the amplitude-restricting signal generator (6), and an adder (8) adds the output (Si) of the amplitude restricting circuit (7) or a signal obtained therefrom, as an edge correction signal (Sj, Sq), to the signal (Sc) of the target pixel. It is possible to obtain an edge-corrected image signal with the horizontal or vertical overshoots having been reduced or removed.
