Abstract:
1. An image processing apparatus, comprising: an imaging unit which acquires a plurality of images with different exposure times; a position offset detection unit which detects an amount of a position offset between the plurality of images with the different exposure times; a combining ratio calculation unit which calculates a combining ratio in case of combining the plurality of images with the different exposure times based on pixel values of an image from among the plurality of images with a longest exposure time and the amount of the position offset detected by the position offset detection unit, wherein the combining ratio calculation unit calculates the combining ratio such that a combining ratio of a short-exposure image from among the plurality of images is larger in proportion to a magnitude of the pixel values of the image with the longest exposure time and such that the combining ratio of the plurality of images with the different exposure times approaches equality as the amount of the position offset detected by the position offset detection unit becomes larger; and an image combining unit which combines the plurality of images with the different exposure times based on the combining ratio calculated by the combining ratio calculation unit.
