<P>PROBLEM TO BE SOLVED: To reproduce a photographed moving image with a brightness intended by a user. <P>SOLUTION: An imaging device comprises: an imaging element unit 4 which images a subject light; a moving image recording unit 14 which records a moving image based on an imaging signal from the imaging element unit; a brightness sensor 6 which detects a brightness of the subject light; an exposure calculation unit 18 which calculates a gain value for setting a frame image which constitutes the moving image being photographed to an appropriate exposure on the basis of the brightness detected by the brightness sensor; an image processing unit 8 which performs gain processing using the gain value calculated by the exposure calculation unit; and an exposure recording unit 22 which associates the gain value calculated by the exposure calculation unit with an identifier of the frame image and records the gain value without updating the gain value when change of the gain value calculated by the exposure calculation unit exceeds a prescribed threshold value. <P>COPYRIGHT: (C)2013,JPO&INPIT |
