  • Shutter for CCD imager
    Patent number: 8345152
    Abstract: A CCD sensor has a shutter to prevent frame shift smear during transfer of an image from the image region to a store region. The CCD sensor has an extended dynamic range, because each integration is in two parts, the second part of which has a different sensitivity than the first part. In order to avoid an asymmetry in the uncovering and covering of the image region, a two-bladed shutter is used.
    Type: Grant

    Date of Patent: January 1, 2013

  • CCD imaging array with extended dynamic range
    Patent number: 8314874
    Abstract: A CCD such as a frame transfer CCD has an extended dynamic range. The image built up in the image region 1 in each integration period is transferred to the store region 2 in each frame transfer period, for example, at a TV signal rate. The dynamic range is increased by dividing the integration period into two parts, and clipping the signal in the first part, but not in the second. The signal is clipped by pulsing the clock electrodes of the image region so as to combine the charges from adjacent wells together, overspill being drained into the anti-blooming structure, consequently reducing well capacity.
