Abstract
An image processing device includes an input unit, a selection unit, a matching unit, an estimation unit and a merging unit. The input unit sequentially inputs images. The selection unit selects a reference image from among the input images. The matching unit calculates a correspondence relationship between a feature point of the reference image and a feature point of a target image. The estimation unit estimates an equation that causes a coordinate system of the reference image to correspond to a coordinate system of the target image using positional information of a pair of the feature points whose correspondence relationship has been calculated by the matching unit by regarding a motion between the reference image and the target image as only a rotational motion of the imaging element. The merging unit merges the input image and the target image to generate the composite image based on the equation.
