Image processing device, image processing method, and storage medium

An image processing device for determining the presence or absence of a moving area 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 pixels in the predetermined screen of interest, based on pixels present in the motion direction across the plurality of the time series screens;
• 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;
• and
• determining means for determining the presence or absence of the moving area based on the motion direction calculated by the motion direction calculating means.
