The present disclosure relates to an imaging apparatus, an imaging method, and a program that allow control of an invisible light component of a captured image without a mechanism that inserts and removes a filter that shields the invisible light component. A luminance composition unit combines a luminance signal of a visible light component of a pixel signal of a captured image including an invisible light component and the visible light component with the pixel signal. A chroma gain amplifier attenuates a chrominance signal of the visible light component. The present disclosure can be applied to an imaging apparatus and the like that include, for example, an optical filter that transmits visible light and infrared light, have pixels in an RGBW array, and perform a Bayer conversion process on a captured image.

Method and apparatus for controlling a luminance composition unit

The present disclosure relates to an imaging apparatus, an imaging method, and a program that enable exposure control on a captured image in a non-Bayer pattern by an exposure control method designed for captured images in Bayer patterns. When a Bayering process is performed on a captured image in an RGBW pixel array, a level correction unit corrects the signal level of the captured image so that an earlier level that is the signal level of each white pixel with the highest sensitivity in the captured image prior to the Bayering process becomes equal to a later level that is the signal level of each green pixel to be used in exposure control on an image in a Bayer pattern that is the RGB image after the Bayering process. The present disclosure can be applied to imaging apparatuses, for example.
