Abstract: An image processing method is disclosed in which a pattern for detecting a line image is compared with the value of image data within a predetermined window of the original image. N-value data is transformed to M-value data based on the result of this comparison. An image can thus be satisfactorily M-value coded without being adversely affected by noise.

Abstract: An image processing method for executing image data conversion between different types of input and output devices having different color reproduction ranges, and an apparatus therefor are disclosed. A device independent color reproduction range is calculated in, e.g., a CIE L*a*b* uniform color space, and a color reproduction range depending on a device such as a binary recording color printer is calculated. Only a saturation is compressed at a compression ratio corresponding to the ratio of the two calculated color reproduction ranges. Thus, when an output device outputs a color image, image qualities (color reproducibilities) of input and output images can be equalized. Even when a color outside the color reproduction range of the output device is to be output, a satisfactory output which preserves gradation characteristics can be obtained.

Abstract: An image processing apparatus prevents an increase in random noise and the like produced by distributing a transformation error, which is produced at the time of a level-number transformation, to unprocessed pixel data. Error data X.sub.n is added to pixel data, which has entered via an input unit, by an adder. Thereafter, the resulting data is subjected to a level-number transformation by a binarizing circuit. Transformation error produced at the time of the level-number transformation is calculated by an error arithmetic unit. The transformation error thus calculated is distributed to unprocessed pixel data by an error-diffusion unit, and the error is accumulated in a line buffer memory as error data. When processing of a prescribed number of lines has ended, a line-number discriminating circuit clears the error data that has been accumulated in the line buffer memory. As a result, an increase in random noise is prevented.

Abstract: A window of n.times.m dot is spread over binarized color image data in an original image in order to multi-levelcode the binary data for various image processes with respect to the multi-level-coded data. A binary window is re-arranged to determine the number of dots to be printed within the window for re-arrangement of the dots so as to correspond to the dot positions in the original image. When the number of dots to be printed is within the number of dots in the original image, the dots are rearranged so as to correspond to the dot positions in the original image, while on the contrary, when the number of dots to be printed is increased or decreased, the number of dots is accordingly increased or decreased based on a table, in which the priority of dot arrangement is provided. For these reasons, it is possible to perform various image processes to meet the characteristics of a desired binary color printer even if the original image contains binary color data, thereby allowing a good color image suitable for the binary color printer to be produced.

Also, the photosensor may have a width which is the same as the image width of the image material, and these features permit accurate readings even from reduced size image material. In another embodiment a register is provided to permit a presetting of the number of lines to be read.
