摘要： An image processing device of the present invention includes a region separating section and a filter processing section. With respect to a picture signal which is read out after resolution thereof in a sub scanning direction has been converted, the region separating section computes maximum density difference and complexity as feature parameters indicative of a characteristic of each pixel in the picture signal. Additionally, with respect to the complexity which is dependent on a size of the resolution in the sub scanning direction, the region separating section carries out a correction in accordance with the size of the resolution in the sub scanning direction, and separates the picture signal into each region by using the maximum density difference and the corrected complexity. In accordance with the size of the resolution in the sub scanning direction and each region separated by the region separating section, the filter processing section performs suitable image processing of the picture signal.

摘要： An image processing device of the present invention is provided with four kinds of sub masks in total including two kinds in a main scanning direction and two kinds in a sub scanning direction, in a main mask constituted by a plurality of pixels including a target pixel. In the image display device, when determining a target pixel of an inputted image data, a difference in a total density of the two kinds of sub masks in a main scanning direction is added to a normalized difference in total density of the two kinds of sub masks in a sub scanning direction, and a resultant value is compared with a threshold value so as to determine if the target pixel is an edge area or not.

摘要： The read out image data is stored in the mask memory in a predetermined mask unit, and binarized into binary value with a predetermined threshold in the binarizing circuit. The binarized image data is output to the main scanning direction-black pixel counting circuit and the sub scanning direction-black pixel counting circuit, respectively, to count black pixels in the main scanning direction and in the sub scanning direction, respectively. The largest value is determined by the comparator, and designated as the linkage degree. With the judging circuit, the area judgement of the character area, the photograph area and the dot area is performed based on the linkage degree.

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.

摘要： An image processing apparatus of the present invention is provided with a region separating section and an automatic adjusting section. The region separating section, upon receiving a reference document having a specified ratio of a character region, a photographic region, and a spot region, recognizes and separates the each region of the received document from one another. The automatic adjusting section (1) counts the number of pixels in each of the separated regions and (2) uses the number of pixels thus counted to change a density conversion table, a filter, or a region separation table so as to adjust the separated state of each region such that the number of pixels thus counted is substantially equal to the number of pixels of the region separation state, thereby improving the accuracy of region separation of the image processing apparatus and the image quality of a final image after it is processed with image processing.
