Abstract: In image processing in which each small area included in color image data, which is represented by C, M, Y, and K, is expressed by a predetermined number of representative colors, values of color parameters are obtained for a small area from the values of the color parameters for C, M, Y, and K for each pixel in the small area, so that the values of the color parameters have degrees of variation being compensated to become smaller in the group as the value for black becomes larger. One color parameter to be targeted is selected (#104) based on the degree of variation in the values of individual color parameters in the group. A reference value to be used for grouping the pixels is obtained based on the relationship between the values of the color parameter to be targeted in the group and the quantities of pixels in the group. Based on the reference value, the pixels are divided into groups (#106), and a representative color for each group is obtained (#109).

Abstract: An image processing apparatus executes an area dividing process on color image data that have been divided into blocks of a prescribed size, and for each block, selects a three-color mode when tone gradation is of higher priority and a four-color mode when resolution is of higher priority, as a color mode for an area averaging process. The image processing device executes a compression process in the selected color mode block by block, and outputs image data in a data format of 256 bit length, regardless of the color mode for compression.

Abstract: A printer divides an input image into a plurality of blocks and extracts a block image corresponding to each of the blocks. The colors of the block image are reduced to, for example, four colors. Index numbers are given to pixels of the color-reduced image, and the four colors are assigned. To a color palette in which color information of the four colors is described in correspondence with the index numbers, object information indicative of the kinds of images (for example, a character, a chart, and a photographic image) is added. Consequently, the handling performance of object information for use in an image processing such as a color conversion process is improved.

Abstract: There is provided an image processing apparatus employing an error diffusion method capable of preventing a pseudo contour attributable to a delayed dot. The image processing apparatus receives an error diffused from a neighboring pixel and corrects a value (an input value of 0 to 1) of a pixel to be processed before it reduces a tone. Then a subtracter calculates an error associated with the tone reduction, which is diffused to a neighboring pixel. Herein, only for an input value of no less than 0.5 an inversion portion multiplies by ?1 an error from a neighboring pixel and an error to a neighboring pixel. Thus a dot can be free of delay to prevent a pseudo contour.

Abstract: A method for compressing image data includes a first step for dividing image data into predetermined areas and determining a representative value about density of pixels in each area, a second step for determining density of pixels included in each area by using the representative value of the area and an interpolation rule, a third step for determining reproducibility of an image obtained, on the basis of the density of pixels determined in the second step, by using the image data and a dither pattern that is used for a pseudo gradation process performed on the image data, and a fourth step for encoding, on the basis of the representative value determined in the first step, for areas that are determined to have a good reproducibility in the third step.

Abstract: A print system includes a computer and a printer. Image data having pseudo gradation with a dither pattern are printed by the printer. The computer divides the image data into predetermined areas, determines whether or not a dot arrangement pattern of image data in each of the areas matches a dither pattern that was used for generating the pseudo gradation, determines a representative value concerning a density of image data within the area if they match one another, and sends data related to the determined representative value to the printer. The printer obtains a representative value of each area from compressed data received from the computer and compares the obtained representative value with the dither pattern so as to reproduce a dot pattern.
