ABSTRACT:
Video camera (camcorder) having the partial magnification recording function for a predetermined object, which can be later reproduced after recording a magnified image on a video tape and to RAM, comprising the division signal generating process A1 to divide the image plane of the view-finder into sectors according to the first control signal when picture is appeared on the image plane of the view-finer, the cursor signal generating process A2 to generate cursor signal that probes a predetermined object according to the second control signal when a predetermined object is positioned in the divided image plane, and the magnified signal storage means A3 to convert the analog signal into the digital signal during the picture recording of the magnified signal and to store the digital signal in the memory device for reproduction. According to the present invention, the camcorder provided with the magnifying and picture recording function not only performs partial magnification recording the predetermined object on video tape, but also provides the efficient surveillance system by storing the record in the memory device and reproducing later in the still form.
