  • Patent number: 6862101
    Abstract: An image processor has a transfer control section that transfers a sequence of image processing and data for image processing to be added or updated from a host buffer to program RAM and data RAM. The host buffer receives the sequence of image processing and data for image processing to be added or updated transferred from a process controller, and temporarily stores the sequence and the data during idle cycle time that a processor array section does not execute image processing. The transfer control section provides controls for transfer so that the sequence of image processing and data for image processing to be added or updated are split into blocks for a plurality of transfer times, and the blocks are transferred from the host buffer to the program RAM and the data RAM.

  • Patent number: 6836346
    Abstract: In the image processing apparatus a matrix selector selects a position matrix for determining the gradation direction. The gradation direction is the direction of a contrast of a gradation at a position of a target pixel and a dispersion matrix for determining a spatial frequency at the position of the target pixel. Further, a pixel interpolator divides the target pixel into still smaller pixels. A table selector selects a conversion table for determining a gradation level of the smaller pixels based on the gradation level of the target pixel, the position matrix and the dispersion matrix.

  • Publication number: 20020036643
    Abstract: In an image-processing apparatus, a digital image signal is stored in a memory, and a memory access control part entirely manages all accesses to the memory with respect to the digital image signal. An image processing part converts the digital image signal stored in the memory into an output image signal to be supplied to an imaging unit outputting a visible image based on the output image signal so that a pixel density of the output image signal is higher than a pixel density of the digital image signal read from the memory and an amount of the output image signal is less than an amount of the digital image signal stored in the memory. Accordingly, the central controlled memory is shared by a plurality of functions so as to effectively use the memory, and a high-quality image can be produced by carrying out a density conversion so as to match the pixel density.

  • Publication number: 20010054126
    Abstract: A SIMD type processor includes a SIMD type arithmetic processing section which performs parallel processing by using a plurality of ALUs; and a global processor 102 that provides data to be arithmetically processed to a register and a data register group and provides the same instruction to each of the ALUs. Upon input of an interruption request for carrying out other parallel processing by interrupting a parallel processing currently carried out by the SIMD type arithmetic processing section, the global processor decides if the other parallel processing requested by the interruption request is to be carried out. The global processor suspends the parallel processing currently being carried out, when necessary. Then, the global processor provides data to be arithmetically processed by the interruption processing to the register and the data register group, and provides the same instruction necessary for carrying out the interruption processing to each of the ALUs.

  • Publication number: 20010050778
    Abstract: To solve problems associated with undesirable duplication of see-through back image in a double-sided input document, a method of and a system for substantially eliminating the undesirable see-through back images initially scanns a front side image and a back side image from the double-sided document and store the scanned images. The front side image has portions, and some of the portions include an original front image as well as a see-through back image from the back side image. An edge amount for each of the portions is determined in the front side image. The see-through back images are separated from the original front images based upon the edge amount. To further improve the correct removal of the undesired see-through back image, the above processed portions having a certain edge are smoothed. Character portions and dot pattern portions are further separated from background portions in the smoothed data.
