Image photographing apparatus, method and medium with stack-type image sensor, complementary color filter, and white filter

摘要

An image photographing apparatus, method and medium that can enhance color reproducibility and sensitivity. The image photographing apparatus includes a filter unit having a first filter region to pass at least one band of an incident light signal corresponding to a complementary color of a first color, and a second filter region to pass all bands of the incident light signal, wherein the first filter region and the second filter region are each formed in one of two adjacent pixels, and an image sensor unit to sense an image from the incident light signal that passes through the filter unit, the image sensor unit including a plurality of photoelectric conversion layers each having a different spectral sensitivity.
