摘要: An image processing apparatus includes an interlace-progressive converter converting an interlace input image into a progressive intermediate image, a motion-vector detector detecting motion vectors of the input image by using a distance shorter than the pixel interval of the intermediate image, a cyclic-coefficient setting unit setting, on the basis of a vertical motion, a first cyclic coefficient for a first type of pixel and a second cyclic coefficient for a second type of pixel, a motion compensator motion-compensating, on the basis of the motion vectors, a past progressive output image to generate a motion-compensated image, and an output image generator generating a progressive output image by adding pixel values of the first type of pixels and the second type of pixels of the progressive intermediate image and the motion-compensated image by using the first cyclic coefficient and the second cyclic coefficient as weights.

摘要: An image processing apparatus includes: a motion detection unit detecting a motion of a subject to be evaluated by using an image of the subject to be evaluated; a correlation calculation unit calculating a temporal change correlation between motion amounts of a plurality of portions of the subject to be evaluated, by using a motion vector indicating the motion of the subject to be evaluated, which is detected by the motion detection unit; and an evaluation value calculation unit calculating an evaluation value to evaluate cooperativity of the motion of the subject to be evaluated, by using the correlation calculated by the correlation calculation unit.
