Abstract:
1. An image processing device comprising: a tracking area setting unit that sets a tracking area in an input moving image obtained by photographing an object; a following feature point setting unit that detects a feature point that exhibits a motion in correlation with the motion of the tracking area and sets the detected feature point as a following feature point; a motion detection unit that detects movement over time of the following feature point within the input moving image; a clip area setting unit that sets a clip area of an image to be employed when a partial image including the tracking area is clipped out of the input moving image for either recording or displaying or both recording and displaying, and that sets a size and a position of the clip area on the basis of a motion detection result obtained by the motion detection unit; a background feature point setting unit that detects and sets a background feature point, which is a feature point in a background part of the input moving image, on the basis of a movement amount and a movement direction over time of a plurality of feature points existing within the input moving image; wherein the motion detection unit detects movement of the following feature point relative to the background feature point; and the clip area setting unit sets the size and the position of the clip area on the basis of a detection result obtained by the motion detection unit in relation to a magnitude and a direction of the movement of the following feature point relative to the background feature point, such that when the movement of the following feature point relative to the background of the input moving image decreases, an area ratio of an image in the tracking area increases relative to the clip area.
