An image forming apparatus including: a conveyance path through which a recording material is conveyed to form an image on the recording material; a reading unit that reads a document conveyed to the conveyance path; and a control unit that controls an image forming unit to overwrite a document image with an image according to a result of the reading in which the document image on the document, which is conveyed to the conveyance path, is read by reading unit.

Image forming apparatus generating overwriting image data

An image processing apparatus includes processors which output first and second image data from input image data. The second image data is applied halftone processing of a higher resolution than halftone processing applied to the first image data. The image processing includes a unit configured to decide a mixing ratio of a pixel using a value based on a sum of an error of the pixel and a change amount of a pixel value at that pixel; and a mixing unit configured to mix pixel values of the first image data and the second image data according to the mixing ratios. When the value based on the sum is increased, the mixing ratio of the second image data decided by the decision unit remains the same or is increased.

An image processing apparatus according to this invention performs the first halftone processing for input image data having the first number of gradations, generating halftone image data having the second number of gradations smaller than the first number of gradations. The image processing apparatus evaluates a pixel value difference between input image data and halftone image data, and calculates quantization error data representing a quantization error generated in the halftone image data owing to the first halftone processing. Then, the image processing apparatus performs the second halftone processing for the calculated quantization error data, generating correction data having the second number of gradations for correcting the quantization error generated by the first halftone processing. The image processing apparatus corrects the halftone image data using the correction data.
