Abstract:
An image processing device for calculating the motion direction of each pixel in a predetermined screen of interest from among a plurality of time series screens, the image processing device comprising:score calculating means for calculating a score corresponding to each of a plurality of motion directions of each pixel in the predetermined screen of interest, based on pixels present in the motion direction across the plurality of the time series screens; and motion direction calculating means for calculating the motion direction of each pixel in the predetermined screen of interest, by processing the plurality of the motion directions based on the scores corresponding to the plurality of the motion directions; direction setting means for setting the plurality of the motion directions of each pixel in the screen of interests; and range setting means for setting a range of extraction for extracting the pixels in the plurality of the screens present in the motion direction set by the direction setting means to calculate the score for each motion direction, wherein the range setting means shifts, in the motion direction, the range of the pixels which is used for calculating the score of the motion direction, and the score calculating means calculates the score for each range of pixels shifted in the motion direction, and calculates a final score of the motion direction based on the resulting scores.
