Title:
IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD
Document Type and Number:
Japanese Patent JP2015195453
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve a problem that an image is darkened due to reduction of an exposure time for the purpose of prevention of image blurring in frames when electronic camera-shake correction is used.SOLUTION: An image processing device 1 has: an input image brightness correcting unit 100 for correcting the brightness of an input image; a frame delay unit 101 for delaying an output image by one frame period; a gain applying unit 102 for applying a feedback gain to an output image which is delayed by one frame period; a motion vector detector 103 for detecting a motion vector on the basis of the brightness-corrected input image and the output image which has been delayed by one frame period; a motion compensator 104 for motion-compensating the output image to which the feedback gain and the one-frame-period delay have been applied, and generating a motion-compensated output image; and an adder 105 for adding the motion-compensated output image and the input image to generate an output image.
