Abstract:
An image sensing apparatus and an image sensing method of the invention are configured in such a manner that an image sensor having two or more different photoelectric conversion characteristics is used, a gain of image signals having the respective photoelectric conversion characteristics acquired by the image sensor is calculated based on the image signals having the respective photoelectric conversion characteristics, and gain control is performed with respect to each of the photoelectric conversion characteristics, using the calculated gain. This arrangement enables to control the imaging sensitivity without changing the dynamic range.
