摘要： An image processing device includes an estimator, a first calculator, a selector, a determination module, and a third calculator. The estimator estimates a motion vector to reference images of an input video from a target pixel of a process target image. The first calculator calculates candidate pixel values corresponding to positions in the reference images. The selector selects a motion vector for which the error is small as many as the number smaller than the number of motion vectors acquired for the target pixel. The determination module determines the candidate pixel values corresponding to the selected motion vectors. The third calculator calculates a pixel value after correction of the target pixel from an arithmetic average or a weighted sum of the candidate pixel value determined equal to or less than the reference and the pixel value of the target pixel.

摘要： A feature pattern (e.g., contours of an object) of an input image to be processed is extracted. A feature pattern (e.g., contours of an object) of a reference image corresponding to the input image is extracted. A comparison is made between the extracted feature patterns of the input and reference images. Their difference is output as the result of the comparison.
