摘要： The amount in offset of toner or the like is used to determine two points sandwiching lattice points of input data and divide the region between the two points equally in N−1. The output values at the two points and each point equally dividing the region are obtained to calculate gradients m1-m8 between any two adjacent ones of the points. Then, difference values dm1-dm7 in gradient between any two adjacent ones of the straight lines are calculated and (N−1) lattice points serving as dividing points are selected from the difference values in descending order. It should be noted that N is smaller than M. Then, the input and output values of the determined (N+1) lattice points N0-N4 are plotted and they are bounded by straight line and thus plotted to linearly interpolate the output data for the input data. Thus, an image processing apparatus can be provided capable of precisely modifying output images with reduced memory capacity.

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.

摘要： In order to efficiently process image data in a circuit dividing single image data into a plurality of data and processing the data with a plurality of MPUs in parallel with each other, the MPUs process image data input through an input image data in parallel with each other. An address bus inputs addresses of the image data, and address memories provided on the MPUs store the addresses of the image data processed by the MPUs respectively. When the image data are completely processed, the image data are output through an output image bus while the addresses of the image data are output through the address bus.
