Abstract:
1. An imaging device comprising: an imaging unit in which a plurality of pixels is arranged in a matrix shape, each of the pixels including at least one unit cell unit including a charge generation unit for generating signal charges corresponding to an amount of an incident electromagnetic wave and a charge transfer unit for transferring the signal charges generated by the charge generation unit, a charge accumulation unit for accumulating the signal charges transferred by the charge transfer unit, a reset unit for resetting the charge accumulation unit, and a signal generation unit for generating a pixel signal corresponding to a voltage of the charge accumulation unit; a first selection unit for selecting a plurality of pixels arranged in a row direction of the imaging unit and controlling an operation of the plurality of selected pixels; a second selection unit for sequentially selecting a plurality of the pixel signals output from the plurality of selected pixels selected by the first selection unit; and an output unit for outputting an input signal to a circuit of a subsequent stage, wherein, in the plurality of pixels arranged in the row direction, the first selection unit simultaneously resets the charge accumulation units of the plurality of pixels, and then the second selection unit sequentially selects a plurality of first pixel signals corresponding to voltages of the charge accumulation units of the plurality of pixels and inputs the first pixel signals to the output unit, and the first selection unit simultaneously transfers the signal charges generated by the charge generation units in the plurality of pixels to the charge accumulation units, and then the second selection unit sequentially selects a plurality of second pixel signals corresponding to the voltages of the charge accumulation units of the plurality of pixels and inputs the second pixel signals to the output unit.
