A photographing apparatus includes an oscillator, a first timing signal generator that generates a first timing signal based on an output signal of the oscillator, a second timing signal generator that generates a second timing signal based on the output signal of the oscillator, a phase difference control unit that is controlled so that a phase difference between the first timing signal and the second timing signal is a predetermined phase difference based on the output signal of the oscillator, a sensor that is driven based on the first timing signal, an image processing unit that generates an image to be displayed based on an output of the sensor, and a display unit that is driven based on the second timing signal and displays an image captured on the sensor.
