摘要： An image forming apparatus can apply a smoothing process to multiple value image data without generation of errors due to an unnecessary smoothing process. A template matching process unit (3) determines whether or not the original image data is to be subjected to a smoothing process, and outputs the original image data together with a selection signal (9) indicative of a result of the determination. A smoothing process unit (4) selectively applies a smoothing process to the original image data based on the determination of the template matching process unit (3) so as to output smoothed image data. A first control signal source outputs a first control signal (10a) representing whether or not application of the smoothing process is permitted on an individual image basis. A second control signal source outputs a second control signal (10b) representing whether or not application of the smoothing process is permitted on an individual pixel basis. A selector (5) selects one of the original image data and the smoothed image data base on the selection signal (9), the first control signal (10a) and the second control signal (10b) supplied thereto.

摘要： A first edge width correction process (2) is carried out in which edge widths are corrected by an interpolation process using zoom ratio control values (RZC) generated according to the edge widths in image data; an enlargement processing process (3) that enlarges the image data with edge widths corrected by the first edge width correction process (2) is carried out; a second edge width correction process (4) similar to the first edge width correction process is carried out on the enlarged image data; and an edge enhancement process that enhances edges in the image data with edge widths corrected by the second edge width correction process is carried out. An image processing apparatus is obtained that mitigates the loss of sharpness in an enlarged image and accordingly makes it possible to provide better picture quality.

Further, an outside area and an inside area of the edge are detected. Edge emphasis is performed on an inside area of the edge for data of achromatic colors. On the other hand, data of chromatic colors in an inside area of the edge is substituted with a minimum data of the pixel under interest and pixels surrounding the pixel. Data of chromatic colors and of achromatic colors in the outside area is substituted with a minimum data of the pixel under interest and pixels surrounding the pixel.
