Abstract:
An imaging apparatus and an imaging method which can obtain an image in which a dynamic range is expanded at one shooting are provided. In a case where a pixel output of a pixel where a specific color separation filter is placed is equal to or more than a predetermined saturation level, based on a pixel output of a pixel which is placed in the vicinity of the pixel where the specific color separation filter is placed, a pixel output for brightness, where the pixel output becomes equal to or more than the predetermined saturation level, of the pixel where the color separation filter of the specific color is placed and the pixel output is equal to or more than the predetermined saturation level is compensated, and thereby a dynamic range of an image sensor is expanded.
