IMAGING APPARATUS, IMAGE GENERATION METHOD AND IMAGE GENERATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To acquire image data of a high dynamic range by correcting camera shake of long-time exposure pixels while suppressing a data amount.SOLUTION: An imaging apparatus is provided which includes: an imaging device 15 formed by arraying a number of pixels; an exposure control part 16 which classifies the pixels of the imaging device into any one of three or more pixel groups which are not overlapped, exposes pixels belonging to one pixel group for a longest exposure time and exposes pixels belonging to the two or more other pixel groups for an exposure time shorter than the longest exposure time and in different timing within the longest exposure time; a deviation amount calculation part 17 for calculating a deviation amount between a plurality of images acquired for the other pixel groups; a camera shake correction part 19 for correcting the camera shake within a longest-time exposure image acquired for the one pixel group; and an HDR composition part 20 for generating a high dynamic range image on the basis of the longest-time exposure image corrected by the camera shake correction part and the plurality of images acquired for the other pixel groups.
