1. An imaging apparatus comprising: an image sensor that exposes a subject image by reading lines sequentially to generate an image; a detector that detects an angular velocity of a shake of the imaging apparatus; a controller that: (i) determines the detected angular velocity as an angular velocity for correction when the detected angular velocity is equal to or less than a predetermined angular velocity and, determines the predetermined angular velocity as the angular velocity for correction when the detected angular velocity is larger than the predetermined angular velocity; and (ii) corrects to reduce an influence of a shake to the image generated by the image sensor by image processing based on the determined angular velocity for correction.
