Abstract:
1. An imaging apparatus comprising: a conversion unit including a plurality of pixels arranged in a matrix of rows and columns, each pixel including a conversion element that has a semiconductor layer arranged between a first electrode and a second electrode and being adapted to convert radiation or light into an electric charge, an output switch element that has one of two main terminals electrically connected to the first electrode and is adapted to perform an output operation to be in a conductive state to output an electrical signal based on the electric charge of the conversion element, and an initialization switch element that has one of two main terminals electrically connected to the first electrode and is adapted to perform an initialization operation to initialize the conversion element and that is provided separately from the output switch element in a conductive state; an output drive circuit adapted to control the output operation in units of rows; an initialization drive circuit adapted to control the initialization operation in units of rows; a readout circuit adapted to perform a signal sample-and-hold operation to temporarily hold an electrical signal amplified by an amplifier circuit including an operational amplifier, an integration capacitor and a reset switch, and a reset operation to reset the integration capacitor by the reset switch; and a control unit adapted to control the output drive circuit, the initialization drive circuit, and the readout circuit, wherein the control unit is adapted to control the output drive circuit, the initialization drive circuit and the readout circuit so that termination of the output operation of a certain row and start of the output operation of another row subsequent to the certain row are performed during a predetermined reset operation and a subsequent reset operation subsequent to the predetermined reset operation and so that the initialization operation of the another row is performed during the subsequent reset operation.
