摘要： An image processing apparatus includes a window setting device for setting a portion of a written region of an image composed of dots in an orthogonal matrix as a window, and for moving the set portion within the written region. A first edge detecting device serves to detect differences between image data of a given dot in the window set by the window setting device and image data of dots neighboring the given dot, and serves to detect directions of the detected differences. A second edge detecting device serves to detect edges between neighboring dots other than the given dot, the detected edges relating to image data differences and image data difference directions respectively equal to the image data differences and the image data difference directions detected by the first edge detecting device. A calculating device serves to provide the edges, detected by the second edge detecting device, with predetermined coefficients respectively, and serves to add the predetermined coefficients for the edges detected by the second edge detecting device to calculate a sum of the predetermined coefficients. A signal generating device serves to generate an image signal which varies a size of the given dot in accordance with the sum of the predetermined coefficients which is calculated by the calculating device.
