Abstract
An image processing apparatus that derives an optical flow which is a set of motion vectors of at least a part of pixels between a plurality of input images includes an acquisition unit and a deriving unit. The acquisition unit is configured to acquire a contrast value of one of the input images. The deriving unit is configured to derive the optical flow based on the contrast value acquired by the acquisition unit and an energy function. The energy function includes a data term specifying a correlation between the plurality of input images and a smoothing term specifying a degree of smoothing.
