  • Image processing device, image forming apparatus, and non-transitory computer readable recording medium
    Patent number: 8711434
    Abstract: An image processing device includes a processor. The processor executes a screen process by using different screens for respective color components which are newly used in response to N colors ranging from a primary color in an output color space to a Nth color, in the output color space, obtained by mixing the primary color with other primary colors in order, where N denotes natural number equal to or larger than 2.
    Type: Grant

  • Image processing device, image forming device, and computer-readable medium
    Patent number: 8699083
    Abstract: An image processing device includes a screen processing unit and a correction processing unit. The screen processing unit executes screen processing for an image to be processed. The correction processing unit performs correction processing of correcting a distortion of an output image from an original image, based on the amount of the distortion, for (i) the image before the screen processing and (ii) the image after the screen processing. The correction amount relating to the correction processing for the image after the screen processing is a small value as compared with the correction amount relating to the correction processing for the image before the screen processing.
