Imaging control device, imaging apparatus, and imaging control method

Abstract

To obtain an appropriate exposure condition even in second photographing when generating an image with an expanded dynamic range. An exposure control unit controls an imaging element including a normal pixel for generating an image signal and a low-sensitivity pixel for generating a low-sensitivity image signal and having lower photoelectric conversion sensitivity to visible light than the normal pixel under a predetermined exposure condition and causes the imaging element to output the image signal and the low-sensitivity image signal. A low-sensitivity histogram generating unit generates a low-sensitivity histogram indicating an appearance frequency distribution of the low-sensitivity image signal based on the low-sensitivity image signal. A short-time exposure condition calculating unit calculates a short-time exposure condition with an exposure time shorter than the exposure condition based on the generated low-sensitivity histogram. A short-time exposure control unit controls the imaging element under the calculated short-time exposure condition and causes the imaging element to output a short-time exposure image signal as an image signal generated by the normal pixel. A combining unit combines the image signal and the short-time exposure image signal.
