Image processing device, image processing method, and image processing program

Abstract

A motion-vector-setting section () sets a first motion vector in units of pixel in a target image. An exposure-time-ratio-setting section () sets in units of image an exposure time ratio that is a ratio between a time interval of the target image and a period of exposure time. A motion-blur-amount-setting section () sets a motion blur amount in units of pixel based on the exposure time ratio and the first motion vector. Based on the motion amount, a processing-region-setting section () sets processing regions as well as a processing-coefficient-setting section () sets processing coefficients. A pixel-value-generating section () generates pixel values that correspond to the target pixel from pixel values in the processing region and the processing coefficients. A motion-blur-adding section () adds a motion blur to an image containing the pixel value generated based on an input second motion vector and the first motion vector. An image-moving section () moves the motion-blur-added image along a counter vector of the second motion vector. Any more real arbitrary viewpoint image can be generated.
