Abstract:
1. An imaging apparatus comprising: a conversion unit including a plurality of pixels arranged in a matrix, wherein each of the pixels includes a conversion element adapted to convert radiation or light into electric charge and an output switch element adapted to perform an output operation of outputting an electric signal based on the electric charge; an outputting drive circuit controlling row by row the output operation of said conversion unit; a plurality of signal wires adapted to transmit the electric signal in parallel outputted row by row from said conversion unit; a read-out circuit having at least an amplifier, an integral capacity, a reset switch, and a sampling and holding circuit, which are provided for each of the signal wires, wherein the amplifier has an inverting input terminal electrically connected to each of the signal wires, the integral capacity is electrically connected to the inverting input terminal and an output terminal of the amplifier, the reset switch is adapted to reset the integral capacity, and the sampling and holding circuit is electrically connected to the output terminal, wherein the read-out circuit is adapted to perform a sampling and holding operation for holding an electric signal read out through a plurality of the amplifiers by a plurality of the sampling and holding circuits, and a reset operation for resetting a plurality of the integral capacities; and a control unit adapted to control said outputting drive circuit and said read-out circuit to perform, during an interval between a first reset operation that is performed at a first output operation in a predetermined row and a second reset operation that is performed successively to the first reset operation, a termination of the first output operation, a start of a second output operation that is performed successively to the first output operation, and the sampling and holding operation after the start of the second output operation.
