ABSTRACT:
An image pick-up apparatus having an optical zoom mechanism and an electronic zoom mechanism, wherein the optical zoom mechanism and the electronic zoom mechanism are adjusted in accordance with information on a position and size of an area recognized as an object (a human face). An image pick-up apparatus in which the control gain for restoring the rotating lens barrel to a reference position is increased by static detection of a housing, thereby attaining a compatibility between a high vibration-proofing performance and a high-accuracy origin restoration. A motion vector detection apparatus, in which by making the motion vector detection area movable, a motion vector is detected without any feeling of disorder regardless of the image pattern. An image swing correction apparatus is also disclosed in which the phase of a read clock of a video memory is adjusted in accordance with the result of detection of a time-base error of the video signal, and read out by a clock of regular intervals. The time base of the video signal is thus corrected while at the same time moving the read position of the video memory in accordance with the result of detection of the swing amount of the whole image, thereby correcting the swing of the whole image.
