摘要： In an image processing apparatus for encoding image data and a method of controlling the same, whether an attribute of each of a plurality of areas in image data corresponds to an edge in an image based on the image data is determined, and one of a plurality of sub-sampling processes is selected according to the determination for each of the plurality of areas. Note that the plurality of sub-sampling processes can sub-sample color difference components of each of the plurality of areas by different processes. By the sub-sampling process selected as that corresponding to each of the plurality of areas, each of the plurality of areas is sub-sampled to encode the image data.

摘要： An image processing which is capable of preventing page missing even when there is an image having no foreground image. In a case where a foreground image is extracted from an obtained image, the foreground image is generated as an image for one page, and in a case where no foreground image is extracted from the obtained image, an image indicating that no foreground image is extracted is generated as an image for one page.

摘要： A system and method facilitating compression of bi-level images with explicit representation of ink clusters is provided. The present invention includes a cluster shape estimator that analyzes connected component information, extracts clusters and stores the cluster in a global dictionary, a page dictionary or a store of unclustered shapes. A bitmap estimation from clusters component determines dictionary positions for clusters stored in the global dictionary which are then encoded. A cluster position estimator determines page positions of clusters of the global dictionary and/or the page dictionary that are then encoded. Further, the global dictionary, the page dictionary and the store of unclustered shapes are also encoded.
