An imaging-displaying apparatus includes an imaging unit outputting an imaging signal; an image processing unit generating an image signal based on the imaging signal, and writing the signal in a VRAM; an image signal output unit outputting the image signal from the VRAM, and outputting the signal to the display unit; and a timing control unit generating an imaging vertical synchronizing signal for driving the imaging unit, generating a display vertical synchronizing signal obtained by delaying the imaging vertical synchronizing signal at least by a predetermined time which is necessary for a generation of an image signal, and supplying the signal to the display unit, and controlling an image signal output unit so that the image signal is read from the VRAM by being delayed by a phase difference between the imaging vertical synchronizing signal and the display vertical synchronizing signal, after outputting the imaging signal from the imaging unit.
