ABSTRACT:
A video camera includes a vibration generation section including a camera body having a lens system with an auto-focus mechanism, an image pickup element, arranged along an optical axis of the camera body, for picking up an optical image obtained through the lens system, and a piezoelectric actuator for linearly vibrating the image pickup element with a predetermined amplitude at a predetermined period along the direction of the optical axis, an image signal processing circuit for A/D-converting a plurality of images time-serially obtained at arbitrary positions within the amplitude of the image pickup element vibrating along the optical axis, and an image memory for storing the plurality of time-serial images, further including an image input processing section consisting of an in-focus decision/extraction circuit for selecting and extracting clear in-focus areas of a predetermined image area, and an image synthesizing circuit for selecting desired ones of the plurality of areas from the image memory and synthesizing the selected areas into one image. The video camera of this invention further includes an intrusion decision function wherein a time-serial image having small positional and time differences is used within picked image coordinates, an optical flow between these features areas is obtained, and intrusion is decided by using the FOE point from which motion vectors of a stationary object are generated from a motion vector string obtained from the corresponding area in this optical flow.
