Video camera with high speed mode |
摘要 |
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.
