Abstract
Official abstract text for this publication.
An imaging apparatus having a solid state imaging device that includes first photoelectric conversion elements and second photoelectric conversion elements arranged in a two dimensional array, comprises a device control unit that performs a driving in which a first signal according to electrical charges accumulated in the first photoelectric conversion elements during a first exposure period and a second signal according to electrical charges accumulated in the second photoelectric conversion elements during each of second exposure periods are read by sequentially exposing the second photoelectric conversion elements for the second exposure periods, each of which overlaps with the first exposure period and has different length of time, during periods overlapped with the first exposure period while simultaneously exposing the first photoelectric conversion elements for the first exposure period.
First claim
