IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND PROGRAM

摘要

In the present invention, a motion-compensated image is generated by employing continuously captured images having different exposure times, and an image subjected to noise reduction and high dynamic range expansion processing is generated by image composite processing which employs the generated motion-compensated image. Positioning is executed between an input image and a previous processed image having different exposure times, and composite processing is executed between the input image and the previous processed image that have been subjected to said positioning processing. A positioning processing unit executes exposure ratio correction between the input image and the previous processed image, detects a motion between the images by employing the exposure-ratio-corrected images, and generates a motion-compensated image in which either the input image or the previous processed image is positioned with respect to the other image. A composite processing unit executes composite processing by employing the motion-compensated image, and thereby generates an output image that has been subjected to dynamic range expansion processing and noise reduction processing.
