摘要：
An imaging apparatus includes a transmitting path to transmit the output electric signal, and a read-out circuit performing a sampling and holding operation for holding the electric signal read out through the transmitting path, and performing a reset operation to reset the transmitting path, and includes a control unit for controlling an outputting drive circuit and a read-out circuit so as to perform the sampling and holding operation row by row after a start of the output operation, to perform the reset operation after the sampling and holding operation, and to terminate the output operation after the reset operation. This can reduce the frame time without reducing the S/N ratio of the image signal.
