An imaging apparatus includes an imaging element, an image signal transmitter, an image signal receiver, a signal processor and a control unit. The imaging element includes pixels arranged in two-dimensional array. The pixels output an imaging signal in synchronization with a first synchronizing signal. The image signal transmitter superimposes a second synchronizing signal on the imaging signal and transmits an image signal. The second synchronizing signal indicates a start position in vertical and horizontal directions in the two-dimensional array and is different from the first synchronizing signal. The image signal receiver receives the image signal from the image signal transmitter, and separates the received image signal into the imaging signal and second synchronizing signal. The signal processor processes the separated imaging signal based on the separated second synchronizing signal. The control unit receives the first synchronizing signal, and controls peripheral circuits in synchronization with the first synchronizing signal.
