摘要： It is an object of this invention to prevent a false edge phenomenon in quantization processing for a multilevel image. In order to achieve this object, according to the invention, (1) a reference threshold (Cthreshold) to be used for error diffusion for a cyan (C) component is obtained on the basis of a density value M of a magenta (M) component. (2) A threshold modulation amount table is referred to by using a combination of a density value C of the C component and the density value M of the M component. (3) A correction threshold modulation amount Cthreshold′ is determined by adding the threshold modulation amount obtained in the second step to the reference threshold Cthreshold to be used for error diffusion for the C component. (4) A density Ct after error diffusion for the C component is compared with the correction threshold Cthreshold′. If the density Ct is higher, a quantization value binDataC of the target pixel is set to 255. If the density Ct is lower, the quantization value is set to 0. The same processing as described above is also performed for the cyan component.

摘要： There is disclosed an image processing apparatus which determines an attribute of an image including a pixel to be processed. An image area having a predetermined size including the pixel to be processed is extracted (S701). A variation related to the image area is calculated based on pixel values included in the image area (S705). Pixels in the image area are converted into N-ary data (ternary data or higher) in accordance with the calculated variation (S709). The attribute of the pixel to be processed is determined by analyzing the N-ary data as a result of the N-ary conversion (S711).

摘要： Upon outputting halftone image data to an output device, density transformation is prevalently performed to improve image quality. Density transformation corresponds to linear gamma correction, and cannot correct for color fog and the like that may occur in a photo image. Hence, lightness and color-difference information of halftone image data is acquired on the basis of low-frequency components of frequency data obtained by transforming halftone image data into spatial frequency components, and a lightness and color-difference transform amount of the halftone image data is set on the basis of the acquired lightness and color-difference information.
