  • Publication number: 20110128408
    Abstract: An imaging apparatus, including an optical system forming an image of an optical image of an object; an imaging element imaging the optical image and producing image data at a frame frequency Ffs out of a frame frequency Ffr of NTSC system; a frame memory storing the image data; and a controller progressively writing the image data in the frame memory and interlacedly reading out the image data from the frame memory at the frame frequency Ffr of NTSC system. The frame memory is divided into at least three areas comprising a writing-in area and a read-out area, wherein the controller sequentially switches the areas of the frame memory and progressively writes one frame of image data in each area and interlacedly reads out one frame of image data from each area in sequence.

  • Publication number: 20100019129
    Abstract: A photoelectric conversion element includes a plurality of light receiving portions. A color filter is provided on a light receiving surface of the photoelectric conversion element with filters for red, green, and blue arranged corresponding to the light receiving portions, such that R, G, and B pixels including the light receiving portions and the filters are arranged in a two-dimensional array. A transfer unit transfers a light in a wavelength range other than lights of green and blue incident on the G pixel and a light in a wavelength range other than lights of blue and green incident on the B pixel to a neighboring R pixel.
