    摘要: To suppress jaggies in second image data on the basis of first image data, the second image data obtained by executing halftoning processing for the first image data, and attribute data representing an attribute of each pixel contained in the first image data, a judgment signal indicating whether to execute smoothing processing is output on the basis of the attribute data. Edge correction data is generated from the first image data by executing smoothing processing in accordance with the judgment signal. The pixel data of the second image data is compared with the pixel data of the edge correction data. The pixel data having a higher density is output. Jaggies generated by halftoning processing can be suppressed with a simple arrangement at a low cost.

    摘要: An image processing device and method for convert multi-value image data having light and dark information per pixel into binary data for pseudo half-tone representation. A binarization results delay unit holds binarized data near the pixel of interest obtained by a binarizing unit, a slice value control unit calculates the amount of change in the slice value based on the concentration of the image or the binarized data pattern thereof, and determines the binarized slice value S based on the amount of change in slice value. The binarizing unit binarizing input image signals using the binarized slice value S. Thus, control of the amount of dot concentration in an arbitrary concentration area, and accurate control of texture can be realized.

    摘要: A two-color separating circuit separates an input image signal into two color signals R and K. In conformity with a color signal indicating the maximum value of the separated color signals, a color-mixture correcting circuit corrects the other color signal. The density of the color pixel formed by the corrected color signal is predicted, and the difference between the result of prediction and the color signal before correction is distributed among pixels of the same color surrounding this pixel. Accordingly, it is possible to provide an image processing apparatus for supplying an image forming apparatus, which collectively forms images of two colors, with an image signal subjected to processing capable of performing excellent color mixing without lowering the density of whichever of the two color-component images is formed last.
