Abstract: The image processing device includes: a first motion vector detecting section detects a first motion vector indicating a motion from a subsequent frame to the target frame; a second motion vector detecting section detects a second motion vector indicating a motion from a previous frame to the target frame; a first moved image generating section generates data of a first moved image based on data of the subsequent frame and the first motion vector; a second moved image generating section generates data of a second moved image based on data of the previous frame and the second motion vector; and a corrected image generating section generates data of a corrected image, based on data of the target frame, and the data of the first and the second moved images.

Abstract: An image processing device configured to synthesize a first image and a second image shot in two or more exposure times different in length in a parallel way within one frame time, includes: a level adjuster configured to adjust the first image and output a corrected first image having a luminance level substantially aligned with a luminance level of the second image; a movement detector configured to calculate absolute values of differences between positionally corresponding pixel pairs in the corrected first image and the second image and accumulate the calculated absolute value on an image block basis to obtain a movement detection amount on the image block basis; a movement blending ratio calculator configured to smoothen the amounts of detected movement and calculate a movement blending ratio between positionally corresponding pixel pairs based on the smoothened amounts of detected movement; and an image synthesizer configured to generate a movement-adaptive image by synthesizing pixels at the corresponding positions at the movement blending ratio.
