Abstract
An imaging control apparatus includes an HDR signal processor and a frame memory. The HDR signal processor obtains pixel data Sand Sobtained by imaging with a very short exposure time Tand a short exposure time Tearlier than obtaining pixel data Sobtained by imaging with a normal exposure time T, generates a luminance image data by separating illumination light component from the pixel data Sand S, the generation of the luminance image data starting when the pixel data Sis obtained, and generates a gain for tone mapping from the luminance image data. On the other hand, the HDR signal processor generates an HDR image data from the pixel data Sto S, the generation of the HDR image starting when the pixel data Sis obtained, and performs tone mapping by multiplying this image data by the gain.
