Abstract: Disclosed herein is an image taking apparatus including an image taking device, a gain adjustment circuit, and a correction circuit. The image taking device operates with timings based on a frame rate determined in advance and the total number of horizontal lines, has an electronic shutter allowing a shutter speed to be adjusted, receives light in a period equal to the shutter speed of the electronic shutter and carries out an opto-electrical conversion process on the light for every horizontal line in order to generate a predetermined signal. The gain adjustment circuit adjusts the gain of the electrical signal received from the image taking device. The correction circuit compares an image taking video signal with a reference video signal to compute a flicker component as a component oriented in the vertical direction of an image represented by the image taking video signal in a flicker correction process of eliminating flickers.
