An image processing apparatus reduces image data on a first rank to generate image data on a second rank, and acquires an evaluation value of sharpness from the image data on the second rank. When the evaluation value is equal to or more than a threshold value, the image processing apparatus acquires a motion vector from the image data on the second rank. The image processing apparatus, based on the acquired motion vector, sets a detection area of correlation between the image data on the first rank, to detect the motion vector on the first rank. When the evaluation value of the image data on the second rank is less than the threshold value, the image processing apparatus does not need to acquire the motion vector in the image data on the second rank but detects the motion vector in the image data on the first rank. |
