  • Patent number: 7810871
    Abstract: A vehicle body side portion structure is disposed with a pair of right and left roof side rails disposed along a vehicle anteroposterior direction on both sides of a roof reinforcement that extends along a vehicle width direction of a roof and connection portions that bond together the roof side rails and the roof reinforcement. First fold portions in vehicle width direction outside end portions of the connection portions are disposed in a position higher in a vehicle vertical direction than second fold portions in vehicle width direction inside end portions of the connection portions. When a side load F equal to or greater than a predetermined value is inputted, the first fold portions rotate and move towards the vehicle upper side with the second fold portions acting as supporting points, the first fold portions become bent so as to become convex towards the vehicle upper side.

  • Publication number: 20090279131
    Abstract: Conventionally, pixel data are converted into the tile sequence. According to this invention, span information or run-length information during conversion into pixel data from vector data such as a display list converted from a page description language is converted into the tile sequence before rendering into pixel data. This can greatly reduce the amount of data temporarily stored for conversion into the tile sequence.

  • Patent number: 7460158
    Abstract: An image processing apparatus, which supplies image signals to an image forming apparatus, includes a storage unit that stores a limiting value of a sum of signal levels of output image signals, an input unit that inputs C, M, Y and K signals, a first comparison unit that compares the limiting value and the sum of the signal levels, an under color removal unit that replaces a predetermined level of C, M and Y signals with a K signal in an under color removal process when the sum of the signal levels of the input signals exceeds the limiting value, a second comparison unit that compares the limiting value and the sum after undergoing the under color removal process, and where the sum after the under color removal process exceeds the limiting value, an adjustment unit that reduces the C, M and Y signals after undergoing the under color removal process at an identical rate so as to reduce the sum to less than the limiting value.

  • Publication number: 20080273218
    Abstract: Raster image data is converted into block vector image data corresponding to blocks each having a predetermined size by segmenting the raster image data into the blocks with the predetermined size and executing vectorization processing. The input raster image data is converted into a block vector image. The converted block vector image is stored in a storage means. Transfer of the image data as a processing target in the apparatus is controlled to output the raster image data obtained by rasterizing the stored block vector image data.

  • Publication number: 20070229888
    Abstract: When rasterized text is pasted on a picture image included in a print image, image processing for a picture region is applied to the print image, thus deteriorating the image quality of a text region. Print data is input from the exterior, and objects included in the print data are rendered to generate image data for print. Attribute information of each object is appended to the image data for print, and the image data appended with the attribute information is stored in a memory. Image data indicating a picture attribute is extracted from the rendered image data for print. The extracted image data is segmented into region. Attribute information of image data of a region of a text attribute, which is divided in the segmentation, is rewritten to a text attribute.

  • Patent number: 7119807
    Abstract: The present invention concerns an image processing apparatus and an image processing method, in which an edge coordinates extraction circuit is used to extract edge coordinates information for an input bitmap. By converting the bitmap image into vector data the edge coordinates information so extracted reduces the time required for raster-vector conversion.

  • Patent number: 6697882
    Abstract: A rendering processor has source, pattern, destination prefetch/write units and DMA controllers. Each DMA controller enqueues a transaction such as a memory read/write in a transaction queue. A memory controller processes transactions in the queue in the FIFO order. A prefetch unit determines whether or not data is prefetched to a line end, and if the determination is affirmative, postpones a prefetch until completion of the write-back of the prefetched data.
