Abstract:
1. A solid state imaging device comprising: a variation detecting means for detecting the period of energy variation of discharge type illumination; an exposure time determining means for determining an exposure time set for each frame or each field in imaging based on the period of energy variation detected by the variation detecting means; an imaging means for imaging, using an X-Y address type solid state imaging element for photoelectrically converting incident light to charges and accumulating the charges in an exposure time; a dividing means for dividing the exposure time into a plurality of exposure times; a separating means for separating the plurality of exposure times, divided by the dividing means, into valid exposure times and invalid exposure times; and a selective output means for selectively integrating charges accumulated in the imaging means only during the valid exposure times among charges accumulated in the imaging means during the exposure time, and for outputting a signal based on the integrated charges, wherein among the charges accumulated by the imaging means, the charges accumulated during the invalid exposure times are drained scan line-by-scan line to a substrate of the imaging element.
