Abstract:
1. An imaging apparatus provided with a solid state imaging device that includes a plurality of first photoelectric conversion elements and a plurality of second photoelectric conversion elements arranged in a two-dimensional array, the imaging apparatus comprising: a driving unit that performs a driving in which a first captured image signal according to electrical charges accumulated in the plurality of first photoelectric conversion elements during a first exposure period and a second captured image signal according to electrical charges accumulated in the plurality of second photoelectric conversion elements during each of several second exposure periods are read by sequentially exposing the plurality of second photoelectric conversion elements for the several second exposure periods while exposing the plurality of first photoelectric conversion elements for the first exposure period; and an image processing unit that performs a processing in which a captured image signal with a dynamic range is generated by using the first captured image signal and at least one of the plurality of the second captured image signals, wherein each of the second exposure periods overlaps with the first exposure period and the processing includes plural types of processing where numbers of the second captured image signals to be used are different, wherein the image processing unit determines a captured image data among the plurality of the captured image data generated from each of the plural types of the processing to be recorded on a recording medium based on the captured image data generated from at least one of the plural types of the processing, and wherein the image processing unit allows any of the captured image data without the saturation area among the captured image data obtained from a processing other than another processing having the smallest number of the second captured image signals to be used among the plural types of the processing to be recorded on the recording medium, and when a captured image data without the saturation area is absent, the image processing unit allows the captured image data obtained from the processing having the smallest number of the second captured image signals to be used among the plural types of the processing to be recorded on the recording medium.
