  • Patent number: 6512545
    Abstract: In a solid-state image pickup apparatus including a pixel section having a plurality of arrayed pixels and a scanning circuit for scanning the pixel section, the scanning circuit is constructed as having: a shift register section consisting of cascaded shift register units; a signal select section consisting of a plurality of signal select units arranged in a manner corresponding to the shift register units; and a scan control section for generating scan control signal for controlling the signal select unit. Outputs of the shift register units are selectively provided as scanning signal through the signal select units which are controlled by the scan control signal. Thereby, pixel signals corresponding to a full angle of view can be read out at a rapid frame rate even in the high-definition solid-state image pickup apparatus where the number of pixels is very large.

  • Patent number: 4937674
    Abstract: A solid-state imaging device composed of static induction transistors arranged in a matrix-like manner between a plurality of row lines and a plurality of vertical signal lines, drive means for simultaneously reading out during a predetermined readout period the signals stored in the static induction transistors, in accordance with row selection signals to be applied to the row lines, and holding them in drive transistors, and successively reading out the signals thus held within the horizontal scanning period, and means for preventing spurious signals from being generated by the ON operation of those static induction transistors to which the row selection signals are not applied. This construction effectively prevents blooming generation due to the superimposition of signals from non-selected static induction transistors.
