The imaging apparatus includes an image sensor for obtaining a picture image from an optical image that is projected to the image sensor through an optical system, an image moving portion for moving the optical image on the image sensor, a motion detecting portion for detecting a movement on the picture image of a moving subject that appears in the optical image, and a control portion for controlling, during an exposure period after a predetermined operation, the image moving portion in the direction of canceling the movement of the moving subject on the image sensor due to a movement of the moving subject in the real space, based on a movement of the moving subject detected in advance. The control portion sets length of the exposure period based on the movement of the moving subject detected in advance.
