  • Patent number: 7750957
    Abstract: A solid-state image sensing apparatus including a solid-state image sensing device and a signal processing circuit. The solid-state image sensing device includes: a vertical transfer unit, composed of transfer columns corresponding to columns of the light-to-electric conversion elements, operable to transfer, in a vertical direction, signal charges read out from the light-to-electric conversion elements; a horizontal transfer unit operable to receive the signal charges from the vertical transfer unit and transfer them in a horizontal direction. The signal processing circuit converts the signal charges from the horizontal transfer unit into pixel data, and rearranges it into a two-dimensional array. In the rearrangement, the signal processing circuit, per transfer of one piece of pixel data, cyclically selects a line memory out of three line memories, writes a piece of pixel data into the selected line memory, or reads a row of pixel data from the selected line memory.

  • Patent number: 7551213
    Abstract: A charge transfer implemented by a transfer section for transferring charges stored in image sensor elements along one direction on a surface where the image sensor elements are disposed is halted for a predetermined length of time. The charges are transferred from the transfer section without reading the charges from the image sensor elements after the charge transfer is halted for the predetermined length of time. A position where a defect is generated in an image pickup sensor is identified based on signal levels of the transferred charges. A defective signal level of the image pickup sensor generated on a line including the defect-generating position and in parallel with the one direction is corrected. As a result of the foregoing process, a display failure is precisely corrected.

  • Publication number: 20070188645
    Abstract: An image output apparatus in which an image output synchronization signal generation circuit conventionally shared for both video (TV) use and liquid-crystal display (LCD) use is divided into two image output synchronization signal generation circuits. The two image output synchronization signal generation circuits are synchronized, and the image format can be changed without taking the current image format into consideration. Thereby, high-definition image formats and liquid-crystal display progressive scanning are supported. Also, a dedicated synchronization counter, which does not have a horizontal counter or a vertical counter, is provided separately from a vertical counter and horizontal counter of a TV image output synchronization signal generation circuit and a horizontal counter and vertical counter of an LCD image output synchronization signal generation circuit.
