  • Patent number: 8405743
    Abstract: An image-data processing apparatus includes a writer which writes image data into a memory according to a non-interlaced-scanning or an interlaced-scanning of each N line. An updater updates a cumulative zoom coefficient by accumulating, for each line, a decimal portion of the cumulative zoom coefficient to a first numerical value corresponding to the zoom coefficient. An accumulator accumulates, for each line, a second numerical value corresponding to an integer portion of the cumulative zoom coefficient. A reader reads out image data in a line corresponding to an accumulated value of the accumulator. A first setter sets N-times the zoom coefficient to the first numerical value in the non-interlaced-scanning, and sets the zoom coefficient to the first numerical value in the interlaced-scanning. A second setter sets an integer portion to the second numerical value in the non-interlaced-scanning, and sets N-times the integer portion to the second numerical value in the interlaced-scanning.

  • Publication number: 20120089858
    Abstract: A content processing apparatus includes a plurality of takers. Each of a plurality of takers runs with reference to any one of N (N: an integer of two or more) of clocks, and the plurality of takers respectively take a plurality of contents. A mixer mixes the plurality of contents respectively taken by the plurality of takers so as to create equal to or less than N of output contents. A changer changes the clock referred to by each of the plurality of takers corresponding to a mode switching. An adjuster adjusts a mixing manner of the mixer in association with a change process of the changer so that a mixing process is executed for every contents corresponding to a common clock.

  • Patent number: 8054345
    Abstract: A digital camera includes a memory, and pixel data cut out from the memory is subjected to ½ horizontal thinning processing by a ½ horizontal thinning circuit when a zooming magnification is equal to or larger than “2”, and the thinned pixel data is written to an image buffer. A zooming circuit performs zooming processing on the thinned pixel data stored in the image buffer. Here, when the zooming magnification is smaller than “2”, the zooming circuit performs the zooming processing on original pixel data being read from the memory and then stored in the image buffer.

  • Patent number: 7585703
    Abstract: There is provided a method for selectively transferring pixel control devices onto a planar display substrate, which method enables prepared pixel control devices to be easily, reliably and inexpensively mounted without inducing any loss of pixel control devices. The pixel control devices (1) are formed in a large number at pitches (5, 6) obtained respectively by dividing pitches (105, 106) on the planar display substrate (100) by natural numbers. The pixel control devices corresponding to the number of the pitches (105, 106) on the planar display substrate (100) are picked up, retained on a transparent thermoplastic resin film (101) formed on the planar display substrate (100) utilizing the plastic deformation of the film and fixed at the peripheries thereof with a transparent ultraviolet curing resin film (104).

  • Publication number: 20080121500
    Abstract: A slider operated to slide by a lever for light is constructed by an arrangement capable of being integrated by inserting a portion thereof to a cylindrical portion of a slide guide portion provided at an insulator. Thereby, an integrating performance can be promoted in comparison with that of a structure of squeezing the slider by 2 parts. Further, a clearance in a height direction of the slider can be controlled by one part of the insulator, and therefore, a variation thereof can be reduced in comparison with that of the case of controlling the clearance by 2 parts.
