<p>PROBLEM TO BE SOLVED: To provide an image processor capable of more appropriately performing block matching in image data in which components having the same color are discontinuously arranged, an image processing method and a program.SOLUTION: An image processor of an imaging device or the like includes an image data acquisition part, and an image composition part. The image composition part generates a first quasi-brightness component image comprising brightness components calculated from color components with respect to an attention region including an attention pixel of a first image and a prescribed number of its adjacent pixels (S3), generates a second quasi-brightness component image comprising brightness components calculated from color components with respect to a matching object region having the same size as the attention region including a pixel comprising the same color component as the attention pixel in a second image and a prescribed number of its adjacent pixels (S9), and performs pattern matching of the first quasi-brightness component image and the second quasi-brightness component image.</p> |
