Image sensing apparatus having a low-resolution monitor, means for reducing the amount of information in an image signal, and switching means for reducing power consumption in various operating modes

摘要

An image sensing apparatus is provided with an image sensor having picture elements; an electronic monitor having a number of scanning lines fewer than the vertical picture elements of the image sensor; and a driving circuit for reading from the image sensor a fewer scanning lines when the apparatus is in a monitor mode than when the apparatus is in an image sensing mode. The driving circuit reads the image sensor in a non-interlacing manner in the monitor mode. A switching circuit shuts off power to unused circuits when the apparatus is in various operating modes.
