Abstract:
A solid-state imaging apparatus, comprising:a solid-state image sensor having a plurality of light receiving elements arrayed thereon, for accumulating in each of the plurality of light receiving elements information charges according to a received object image; a driving circuit for discharging the information charges accumulated in each of the plurality of light receiving elements of the solid-state image sensor for every vertical scanning period, and for outputting, after a predetermined period, information charges accumulated in each of the plurality of light receiving elements whereby an image signal according to the information charges is obtained; first exposure information generating circuit for detecting a level of the image signal in a predetermined cycle to generate first exposure information which is increased or decreased based on a detection result; second exposure information generating circuit for calculating second exposure information based on the current level of the image signal; selecting circuit for selecting either the first exposure information or the second exposure information; and timing control circuit for setting discharge timing and output timing to the driving circuit; wherein the first exposure information generating circuit generates the first exposure information based on the second exposure information during a predetermined period, and the selecting circuit selects the second exposure information during the predetermined period, and subsequently selects the first exposure information.
