IMAGE PROCESSOR AND IMAGE PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an image processor and an image processing method for calculating a motion vector by a little calculation quantity.

SOLUTION: This image processor is provided with a frame memory for storing first and second image data, a memory 2 including a plurality of elements 20 and a control part. The elements 20 are provided with a picture element 21-1 for storing a first picture element value of a first picture element of the first image data; a picture element 21-2 for storing a second picture element value of a second picture element of the second image data; a minimum picture element difference storage part 22 for storing a first difference value; a motion vector storage part 23 for storing phase information; a comparing-renewing part 26 for outputting renewal information according to renewal by renewing a second difference value as the first difference value according to a comparing result, by comparing the first difference value stored in the minimum picture element difference storage part 22 with the second difference value of a difference between the first picture element and the second picture element; and a renewing part 27 for renewing the phase information according to the renewal information.
