摘要： The image forming device according to the present invention performs resolution conversion processing or scaling processing of a binary image and outputs a processed image. The present image forming device is provided with an edge detecting section, which, during resolution conversion or scaling of the binary image, detects edges of the image and detects lengths and shapes of the edges, and with an interpolated/skipped line producing section, which performs resolution conversion processing or scaling processing based on the lengths and shapes of edges detected by the edge detecting section.

摘要： An image forming apparatus of the present invention includes (i) an image interpolating section for calculating interpolation point and interpolation density of the interpolation point when subjecting a binary image to resolution conversion and scaling and (ii) an offset amount correcting section for giving an offset beforehand when the image interpolating section calculates the interpolation point. As a result, the image forming apparatus can comply with unrounded magnifications of other than integral multiples and a desirable image even with respect to a character image and a pseudo-halftone image.

摘要： An image processing apparatus includes a pixel number transforming section for processing input image data composed of a plurality of regions, each being represented by a plurality of pixels with a pixel number transformation, by performing an interpolation or a decrimation on a pixel. It further includes a region decision value extracting section for extracting a region decision value of a region that a target pixel belongs to, based on characteristic amounts representing characteristics of a block composed of the target pixel and a plurality of pixels around the target pixel, each pixel of the image data being considered to be the target pixel. A controller controls a sequential order of a filtering process and pixel number transformation process to be applied to a region, based upon the transformation increasing or reducing a number of pixels in a region. Finally, a region decision value transforming section is included for calculating a region decision value of each region processed with the pixel number transforming process by an interpolation or a decrimation of the region decision value as extracted from the input image data.
