Title:
IMAGE PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/069103
Kind Code:
A1
Abstract:
Disclosed is a method for correcting for shimmer due to thermal turbulence, even for moving subjects, on a time smoothed base. The device is provided with: a movement compensation means (202) that, for a correction-targeted block (205) of a correction-targeted image within an input image (21), uses a temporally proximate correction image (206) to derive movement information about a moving object, performs motion compensation, and outputs a correction block (208) and a cost value (209); and a shimmer correction means (203) that carries out time averaging processing, in accordance with the cost value (209), of the correction-targeted block (205) and the correction block (208), and outputs a corrected block (211) in which shimmer of the moving object has been corrected, and correction information (210). Through two-stage motion detection, the movement compensation means (202) extracts and compensates for movement of a moving object, in a manner unaffected by thermal turbulence.
