    • A video camera includes a CCD imager, and an image corresponding to a camera signal outputted from all of charge areas of the CCD imager is outputted on a monitor in a normal mode. In a quadruplication mode, four (4) images corresponding to camera signals repeatedly outputted from one of quarter areas of the charge area are outputted on the monitor. A high-frequency luminance component value generation circuit generates a high-frequency luminance component value on the basis of a luminance signal to be outputted at a center of the monitor in the normal mode, and a high-frequency luminance component value on the basis of a luminance signal to be outputted at a center of one of quarter areas of the monitor in the quadruplication mode. A microcomputer controls a focus motor on the basis of the high-frequency luminance component values obtained in such manners so as to adjust a focus.

    • A video camera includes a solid-state image sensing device, and an electric signal from the image sensing device is converted by a camera circuit into a video signal which is further converted into a digital video signal by an A/D converter. The digital video signal is stored in a field memory sequentially field by field under control of a memory control circuit. A motion detecting circuit which receives the digital video signal calculates correlative values for each of a plurality of blocks constituting a whole screen according to a representative point matching method. A microcomputer calculates motion vectors of respective blocks on the basis of correlative value data from the motion detecting circuit and an average motion vector thereof, and calculates "increase", "passing degree" and "variation". The microcomputer further evaluates a reliability of each of the blocks according to a fuzzy inference by utilizing the increase, passing degree and variation as parameters. The memory control circuit determines correction amount for a picture stabilization on the basis of the reliability and the average motion vector.
