  • Publication number: 20110134289
    Abstract: In an image pickup apparatus including a plurality of pixels arranged a matrix of rows and columns, a correction unit performs a correction process based on an electric signal output via a first switch element of a particular pixel and a correction electric signal output via a second switch element of the particular pixel. A correction image signal based on the correction electric signal output via the second switch element is acquired in a period that partially overlaps in time a period in which an image signal based on the electric signal output via the first switch element is acquired. When the electric signal associated with the image signal is output for the particular pixel, the second switch element of the particular pixel is controlled to be in an on-state over a period during which the first switch element of the particular pixel is in an off-state.

  • Patent number: 7923695
    Abstract: Sensitivity is freely changeable to another one in correspondence to a photographing mode, and both still image photographing and moving image photographing for example which are largely different from each other in dosage of exposure to radiation and which are also different from each other in required sensitivity are carried out so as to meet that request. A source or drain electrode of a TFT 21 is connected to a signal output circuit 3 through a signal line 14a and an IC 5. A source/drain of a TFT 23 is connected to the signal output circuit 3 through a signal line 14b and the IC 5. Thus, in each pixel 6, any one of the signal lines 14a and 14b is freely selectable when a signal is read out.
