摘要： An image processing apparatus processes multivalued color image data that includes a plurality of color components. The apparatus includes an adding unit to add per-color-component quantization error values from a neighboring pixel to respective ones of a plurality of color components included in a pixel of interest, and a quantization unit to correlate a sum of the values of each of the color components to which the error value has been added by the adding unit to a sum of values after conversion, and deciding the value of each color component after conversion upon distributing the sum of pixel values after the conversion in accordance with the ratio of each of the color components before conversion. In addition, a coefficient decision unit decides diffusion coefficients, which diffuse quantization error to neighboring pixels, based upon the value of each of the plurality of color components included in the pixel of interest.

摘要： Disclosed are an image processing apparatus and method for the purpose of preventing overlapping of dots between two colors in low-density areas in color pseudo-grayscale processing, thereby obtaining excellent placement of the dots of each color. When a color image is binarized, an error is added to a respective one of color components (I0,I1), after which output decision means (2) decides an output value in accordance with the value of the sum in such a manner that the sum of pixel values after conversion will be rendered constant. Error calculation means (3-0, 3-1) calculate differences between pixel values before and after binarization as errors, and error diffusion means (9-0, 9-1) calculate values to be diffused to a neighboring pixel. Weighting coefficients used at such time are decided in accordance with combinations of values of the color components (I0,I1) of pixel values in the original image. The output value decided by the output decision means (2) is printed out by a printer or the like.

摘要： This invention provides a printing apparatus which employs a print head constructed to minimize a memory area to hold ejection data and not requiring a sophisticated manufacturing technology and thus realizes a print mode to perform a higher-than-normal-resolution printing, making it possible to form a high quality image when needed. For each of cyan and magenta that make large contributions to the formation of an image, four nozzle arrays are allocated. For each of the remaining colors, two nozzle arrays are allocated. For cyan and magenta, the interval between adjoining nozzles of the paired two arrays is set to ¼ the nozzle pitch. For cyan and magenta, all of the four nozzle arrays are used in the high resolution print mode and, in the normal print mode, only two of the four nozzle arrays are used for printing. Of the paired adjoining nozzle arrays, only one is used.
