摘要： There is provided an image processing apparatus for applying an adjusting process to an image including multicolor image signals. An image area including a pixel to be processed is extracted, and one representative signal value is generated from signal values corresponding to a plurality of colors of pixels included in the image area (S2501). A feature amount associated with the image area is calculated based on the representative signal value (S2503, S2505, S2511), and a substitute candidate pixel common to the plurality of colors is selected from the image area based on the calculated feature amount (S2512). Signal values of the pixel to be processed are substituted by new pixel values, which are calculated from the signal values of the pixel to be processed and signal values of the substitute candidate pixel.

摘要： This invention allows printing an image with less image deterioration with respect to a document including both text and an image. An image processing apparatus includes a pixel value acquisition unit which acquires a pixel value of a pixel as a target in an input digital image, and a pixel value correction/modification processing unit which executes a correction/modification process based on the pixel value of the pixel acquired by the pixel value acquisition unit. The pixel value correction/modification processing unit includes a contrast correcting unit which executes contrast correction based on information representing a brightness value corresponding to the pixel value of the pixel, and an intermediate color removing unit which removes intermediate color in the digital image by replacing the pixel value of the pixel by pixel values of pixels around that pixel.

摘要： An adapter capable of communicating with an image supply device and an image output device and allowing direct printing even when a plurality of images are transferred at the same time from image supply devices. The adapter transmits a print request associated with a first image to the image output device. If acquisition of a second image is completed before acquisition of the first image completed, the adapter transfers the second image instead of the first image as the image to be printed.

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).
