摘要： There is disclosed an image processing apparatus for processing an image signal in which the mode of image processing is rendered variable to adapt to plural input devices. More specifically, a conversion matrix circuit receives image signals from one of a plurality of different input devices and converts the image signals into corrected additive primary color signals red, green and blue. The conversion matrix circuit compensates for any differences in the spectral characteristics of the different input devices. The matrix includes a plurality of conversion tables stored in memory for performing the conversion. A selected one of the conversion tables is addressed by the image signals.

摘要： A halftone image recording apparatus has a photoelectric converter for generating a density signal representing the density level of an image, a periodical or random signal generator for periodically or randomly generating level signals, an adder for adding the density signal and the level signals, a memory for storing the addition signal from the adder, a pattern generator for generating an image pattern, and an ink jet head or the like to record the image pattern. Pseudooutlines are eliminated without requiring an increase in the reading resolution and without imparing the resolution during recording. Input image data is compressed and a memory of smaller capacity can be used.

摘要： 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.

摘要： 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.

摘要： 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.
