    摘要: An image forming apparatus wherein an image material is exposed and read by a line-configured photosensor. The line readings by the photosensor are converted into electrical signals which are put out in serial form. In one embodiment the image material is moved at a predetermined speed for scanning wherein the exposure and photosensor devices are fixed. 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.

    摘要: A copying method and apparatus in which a first and a second original image are prestored in a memory, and a desired number of volumes is set for copying that number of volumes with the copies of the first and second original images stored in the memory as one volume. The first and second original images are successively read out from the memory when the set number of volumes is plural. The read-out images are successively printed on a first and a second copy medium and the read-out and print of the first and second original images are repeated over the times corresponding to the set number, thereby producing a desired number of volumes of copies having the first and second original images arranged in order of the page number.

    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.
