摘要： The inventive image processing apparatus takes steps of 1) dividing an image to be processed into numerals of blocks; 2) determining whether a block is a color block or not; 3) determining whether the image is a color image or not based on the rate of color blocks to the entire blocks. Thereby, valid color pixel rate can be obtained at blocks belonging to a color region even though an image is almost monochrome but partially colored. Accordingly, the inventive image processing apparatus can appropriately determine whether the image is a color image or not.

摘要： A method and device for processing image data for a document includes the steps of reading RGB image data for the document; dividing the document image data into a plurality of blocks including a prescribed pixel matrix; calculating an average value information and a gradation range index for each of the blocks; converting the data for each pixel of each of the blocks into coded image data based on the average value information and the gradation range index so that the coded image data defines each pixel with fewer gradation levels than the original image data; storing in a memory unit the gradation range index and coded data, which were obtained for each block through the converting step; forming letter distribution histograms for a primary scanning direction and a secondary scanning direction for each block determined to belong to a letter image; identifying a direction in which letters of the document are aligned based on a number of change points in the histogram for the primary scanning direction and a number of change points in the histogram for the secondary scanning direction; decoding the coded data for each of the blocks based on the respective average value information and gradation range index in the memory unit for the block; and forming an image on copy paper based on the decoded data.

摘要： A pixel interpolating device using the IM-GPDCT method and capable of preventing noise generation divides an original image into a plurality of blocks and picks up a block to be processed as a target block. Further, an image peripheral to the target block is extracted as a peripheral image. By using the peripheral image as an extension region, DCT transform is carried out. Thereafter, the peripheral image is magnified, and the IM-GPDCT processing is carried by using the magnified image.
