  • Publication number: 20050082572
    Abstract: A semiconductor integrated circuit has a nonvolatile memory and a logic circuit which uses information stored in the nonvolatile memory to perform logical operation. The nonvolatile memory comprises bit lines, word lines, and memory cells. The memory cell comprises MOS transistors whose gate electrodes are connected with a word line. Information storage is carried out according to whether one source/drain electrode of the MOS transistors is connected with a source line or floated. During other periods than a predetermined period in the operation of accessing the memory cell, the potential difference between the source/drain electrodes of the MOS transistors constituting the memory cell is zeroed. Subthreshold leakage current is prevented from passing through the memory cell on standby. During the predetermined period in accessing operation, a potential difference is produced between the source/drain electrodes of the MOS transistors. Therefore, the bit line potential can be varied by word line selection.

  • 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: 20040255175
    Abstract: The image processing device comprises a first function block section formed of functional blocks which require a supply of power so as to maintain the image processing device in an operating state when the power supply is on, and a second function block section formed of functional blocks which need not be supplied with the power so as to maintain the image processing device in an operating state even when the power supply is on. The supply of power to the second function block section can be stopped when desired, while continuing the supply of power to the first function block section, thereby saving the power.

  • Publication number: 20030090742
    Abstract: An image processing apparatus and an image scanning apparatus detect a position of an abnormal pixel caused by obstruction to reflected light from a manuscript due to dust and others and correct the abnormal pixel by using data of normal pixels surrounding the abnormal pixel on the basis of a result of the detection. Based on image data read from a null-image prior to optical reading of a manuscript, an abnormal pixel detecting part detects the position of the abnormal pixel caused by the dust and others lying on a contact glass equipped between the manuscript and a CCD. An abnormal pixel correcting part uses pixel information at the position of the abnormal pixel detected by the abnormal pixel detecting part to correct image data read from the manuscript.

  • 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.
