Control circuitry variably sets storage times of the image sensor and an image composer composes an image signal for one picture from a plurality of readout signals from the image sensor having different charge storage times.Field of SearchExposure controlAutomatic control of iris, stop, or diaphragm Based on image signal Contrast Based on ambient light With object or scene illumination Flash or strobe Solid-state image sensor Accumulation or integration time responsive to light or signal intensity In charge coupled type image sensor Including noise or undesired signal reduction Color TV Dark current Smear Field or frame transfer type In charge coupled type sensor In charge coupled type sensor Focus control HAND-HELD CAMERA WITH RECORDER IN A SINGLE UNIT | |
