    摘要: An image processing apparatus performs color conversion processing on an input image. The image processing apparatus includes a block pallet conversion unit, a first color converting unit and a restoration unit. The block pallet conversion unit converts the input image in units of blocks into (i) pallet color information including pallet colors number of which is less than pixels included in one of the blocks and (ii) selection information used to select one of the pallet colors for each pixel. The first color converting unit performs color conversion on the pallet color information obtained by the block pallet conversion unit. The restoration unit selects for each pixel, based on the selection information, one of the pallet colors of the pallet color information, which is color-converted by the first color converting unit, to restores an image.

    摘要: A sender device 1 stores, in header information about image information, information indicating that attribute information and image data rearranged in sequence, and produces image information by means of storing attribute information and image data in a predetermined sequence. The thus-produced image information is sent to a receiver device 2 by way of a network line 3. When receipt of image information is initiated, the receiver device 2 refers to the header information, thereby determining presence/absence, in the header information, of information indicating that attribute information and image data are stored in a predetermined sequence. When it has been determined that attribute information and image data are arranged in a predetermined sequence, image data included in the received image information are immediately decompressed, and the thus-decompressed image data are output in the form of a record or display.
