ABSTRACT:
In an imaging apparatus capable of selectively performing an imaging operation in normal imaging mode and that in composite imaging mode, an object is imaged by performing the imaging operation in normal imaging mode to generate an exposure image signal, a brightness rate of a bright portion and dark portion of the object is calculated by detecting the exposure image signal, an exposure rate, which is a ratio of a long-time exposure time and a short-time exposure time in composite imaging mode, is calculated, and the imaging mode of the imaging apparatus is switched from the normal imaging mode to the composite imaging mode based on a comparison result of the brightness rate and the exposure rate.
