Japanese Patent JPH07110041

Kind Code:

B2

Abstract:

There is disclosed an image processing apparatus for emphasizing edge components of an image signal to be provided from an image input system. The apparatus further comprises a mode selector for receiving predetermined data of a frame signal applied from a frame memory and determining if a pixel corresponds to one of a mode for emphasizing edge components of the image signal, a mode for smoothing uniform components of the image data and a normal mode in accordance with relations of adjacent pixels of the image signal to generate respective controlling signals for the respective modes; an emphasizing circuit for performing a first calculating operation so as to generate an edge component emphasizing data, when a controlling signal from the mode selector is provided for the edge component emphasizing mode; and a smoothing circuit for performing a second calculating operation so as to generate an uniform component smoothing data, when a controlling signal from the mode selector is provided for the smoothing mode. According to the circuit, since the circuit can emphasize edge components of an image signal to be displayed or written, it is possible to enhance quality of an image.
