Abstract:
An imaging apparatus includes a motion detection unit that detects motions of panning, tilting, and camera-shake as motion information. A motion determination unit determines a motion occurring in the imaging apparatus as motion information. A highpass filter (HPF) removes a low-frequency component of a signal of the motion information and a lowpass filter (LPF) removes a high-frequency component of an output signal of the HPF. A swing-back detection unit detects a period in which a motion of swing-back occurs from an output signal of the LPF and a determination result of the motion determination unit A motion vector detection unit detects a motion vector between a plurality of input images. An image cutout unit performs a process of cutting out a partial image from an input image at a position at which the motion of swing-back is reduced during the period in which the motion of swing-back is determined to occur.
