Abstract:
1. An image processing apparatus comprising: input means for inputting color image data; generating means for generating flag data indicating an attribute of an image corresponding to the color image data from the color image data, with respect to each pixel of the image, the flag data indicative of a character, a figure or a mesh with respect to each pixel of the image; first pixel density converting means for pixel density converting the image data at a designated magnification; second pixel density converting means for pixel density converting the flag data in accordance with the designated magnification; and output means for making a process of the pixel density converted image data different every pixel in accordance with the flag data and outputting the processed image data, wherein a pixel converting method of said first pixel density converting means is different from a pixel converting method of said second pixel density converting means, said second pixel density converting means makes a converting method different in accordance with attributes of the flag data, and said second pixel density converting means, when the designated magnification is reduction, performs an arithmetic operating process of flag values using a plurality of pixels near a target pixel with respect to the flag data indicative of a character and a figure, and performs a processing using a nearest neighboring pixel of the target pixel, with respect to the flag data indicative of a mesh.
