摘要： An image processing apparatus for outputting an image by a printer or a display is provided, in which color reproducibility in the image output of plural pages becomes uniform. The apparatus comprises an image memory for memorizing image data of all pages of one output job that is given to an output device, decision portion for deciding whether the image data of all pages are data within a color reproduction range of the output device or not. A color compression process is performed for the image data of all pages uniformly only when it is decided that the image data of all pages are not data within the color reproduction range of the output device.

摘要： The present invention relates to image forming apparatuses such as copying machines, facsimile devices, and complexes thereof. When the image is produced as rotated by 90 degrees or 270 degrees by the rotary processing part 307 while the scanning speed of the original document is finely adjusted so as to be lowered, the control of the magnification is carried out so that the produced image will be contracted in the main direction and enlarged in the sub direction by an mount corresponding to the amount of adjustment made on the operating panel. On the other hand, when the scanning speed of the original document is adjusted to a higher level, the control of the magnification is carried out so that the output image may be enlarged in the main direction and contracted in the sub direction by an amount corresponding to the amount of adjustment to be made on the operating panel.

摘要： The present invention relates to an image processing apparatus for carrying out a variable scale magnification processing for contracting or enlarging an original image. The image processing apparatus including a variable scale moving unit for increasing pixels in accordance with a variable scale magnification in order to enlarge the original image includes a smoothing processing unit for smoothing pixel data. The smoothing processing unit detects the number of increased pixels for each pixel by an increased pixel number determining unit, so as to smooth image data output from the variable scale magnification moving unit by employing smoothing filters of a matrix size selected in accordance with the result of the detection. This results in an image processing apparatus that can prevent a degradation in image quality by an appropriate smoothing processing independently of whether a variable scale magnification in enlargement is integer or not.
