  • Patent number: 7289155
    Abstract: An automatic exposure (“AE”), control apparatus to prevent exposure errors resulting from “smear.” Image-capturing is performed at a single exposure time TI (I=1, 2, . . . n); a CCD output is applied with a CCD drive signal to perform an integrating operation for a signal in an AE area using an integration circuit, and then outputs integration value EI+SI at each exposure time. A shutter trigger operation presents readout of an exposure value. An integrator value En+Sn obtained just before the shutter trigger operation, and a smear value Sn? obtained just after the shutter trigger operation are provided to an exposure operation/control circuit. The exposure operation/control circuit then performs an AE operation to receive En+Sn?Sn?En and compares the value to a target value for determining exposure conditions, and provides an AE operation value containing almost no smear component to determine an appropriate exposure condition.

  • Publication number: 20050140990
    Abstract: An image processing apparatus processes image data two-dimensionally arrayed in vertical and horizontal directions. A vertical size changing section changes a size of the image data in the vertical direction. A horizontal size changing section changes the size of the image data changed by the vertical size changing section in the horizontal direction. A display section displays the image data changed in size in the vertical and horizontal directions.

  • Patent number: 6906748
    Abstract: An interpolation calculation circuit for improving the image quality for recording and display is provided. The interpolation calculation circuit interpolates a necessary pixel on the basis of interpolation calculation (cubic interpolation processing) by an approximate expression of an interpolation coefficient of at least 3rd-order. This cubic interpolation processing is applied to basic processing of an electronic camera, i.e., 3-CCD processing, format conversion, and image enlargement/reduction. In consideration of the operation load on the electronic camera, cubic interpolation processing is performed in accordance with the image sensing mode or the like only when it is necessary, thereby controlling whether execution of interpolation processing is enabled/disabled.

  • Patent number: 6882366
    Abstract: An electronic imaging system includes a CCD image sensor arrangement having a two dimensional array of pixels. The pixel array converts light incident thereon to an electric signal. The pixels are arranged in a plurality of horizontal rows or lines, the lines being arranged vertically. A control arrangement selectively controls operational modes of the system. One mode provides for sequential scan reading out of pixel signals for entire lines of the CCD for still picture recording. Another mode provides for reading out pixel signals concerning k (k is a positive integer) vertically continuous lines of the CCD for still picture recording or dynamic image processing. Thus it is possible to provide a high pixel density solid-state image sensor output at a high frame rate without use of any high drive frequency.

  • Patent number: 6661451
    Abstract: An imaging apparatus includes an interline type CCD image sensor having 1,000,000 or more pixels, which has a Bayer configuration color filter suitable for reading all pixel signals in a line-sequential scanning manner. The imaging apparatus drives the CCD image sensor in a high speed mode usually, and in a high quality image mode only for a trigger depression. In the high speed mode, the CCD image sensor outputs pixel signals for one line at intervals of three lines in the vertical direction. During the high speed mode operation of the CCD image sensor, images are displayed on a liquid crystal display portion at a frame rate of 60 frames/second, the images being recognized by the human eyes as a dynamic image, i.e., a motion picture.

  • Patent number: 6618090
    Abstract: In an automatic exposure control apparatus, image-capturing is performed at a double exposure time TI (I=1, 2, . . . ) and a single exposure time; a CCD output therein produced is applied with a CCD drive signal to perform an integrating operation for a signal in an AE area by using an integration circuit, and then outputs integration values 2EI+SI and EI′+SI′ to an exposure operation/control circuit; and the exposure operation/control circuit then performs an AE operation to receive 2EI+SI−(EI′+SI′)≈EI and compares the value to a target value for determining exposure conditions, and upon receipt of a shutter trigger, it uses an AE operation value containing almost no smear component to determine an appropriate exposure condition even in actual image-recording. According to the apparatus herein stated, exposure errors resulting from smears can be prevented.

  • Patent number: 4816935
    Abstract: A system for automatically erasing a pair of tracks whenever a designated track to be erased belongs to a pair of tracks representing a frame picture.In the system, detecting means detects ID codes indicating field/frame recording mode of a recorded track and feeds a detected signal to a controller, then the controller takes an appropriate action to erase the pair of frame recorded tracks by timely activating head accessing means and an erasing signal generator based on the ID codes, whenever the tracks correspond to a frame picture.
