摘要
A device and method that serve to generate an accurate evaluation-value table and to detect a correct motion vector are provided. A weight coefficient W is calculated on the basis of correlation information of a representative-point pixel and flag-correlation information based on flag data corresponding to pixel-value difference data between a subject pixel and a pixel in a neighboring region of the subject pixel. A confidence index is generated on the basis of the weight coefficient W calculated and an activity A as an index of complexity of image data, or a confidence index is generated on the basis of similarity of motion between the representative point and a pixel neighboring the representative point, and an evaluation value corresponding to the confidence index is accumulated to generate an evaluation-value table. Furthermore, correlation is checked on the basis of positions or pixel values of feature pixels neighboring the subject pixel to determine a motion vector.
