Abstract:
1. An image-processing apparatus comprising: a motion-vector-setting section that sets a motion vector in units of pixel in a target image; a target-pixel-setting section that sets a target pixel for each image in plural images to be processed based on the motion vector set in the motion-vector-setting section; an exposure-time-ratio-setting section that sets an exposure time ratio that is a ratio between a time interval of the target image and a period of exposure time, wherein the period of exposure time is greater than zero; a motion-blur-amount-setting section that sets a motion blur amount in units of pixel based on the motion vector set in units of pixel in the motion-vector-setting section and the exposure time ratio set in the exposure-time-ratio-setting section; a processing-region-setting section that sets a processing region corresponding to the target pixel set for each image in the target-pixel-setting section based on the motion blur amount set in the motion-blur-amount-setting section and a motion direction corresponding to the motion vector; a processing-coefficient-setting section that sets a specific processing coefficient based on the motion blur amount of the target pixel set in the motion-blur-amount-setting section or sets a processing coefficient that corresponds to the motion blur amount and the motion direction of the target pixel; and a pixel-value-generating section that generates a pixel value that corresponds to the target pixel by linear combination of a new pixel value for processing generated corresponding to the motion direction from the pixel value corresponding to the pixel in the processing region set for each image and the specific processing coefficient set in the processing-coefficient-setting section or by linear combination of the pixel value corresponding to the pixel in the processing region and the processing coefficient set corresponding to the motion blur amount and the motion direction of the target pixel.
