Abstract:
An image pickup apparatus comprising:a plurality of pixels each including a photoelectric conversion device, and an amplification device arranged to amplify a signal from said photoelectric conversion device; a common output line to which signals from said plurality of pixels are read out sequentially from said amplification devices; a load device arranged to function as a load of the amplification devices which are connected to said common output line; and a control circuit arranged to supply a first voltage to an input portion of a said amplification device included in a selected pixel from which a signal is selected to be read and to supply a second voltage which is greater than zero and lower than the first voltage, to the input portion of amplification devices included in the non-selected pixels from which signals are not selected to be read, wherein in case that a voltage of the input portion of the amplification device included in the selected pixel falls below a predetermined voltage due to a signal accumulated in said photoelectric conversion device, the signal read to said common output line appears to be based on the second voltage supplied to the input portion of the amplification device included in the non-selected pixels.
