Abstract

An imaging processing device and an imaging processing method that can solve a problem generated in visible light photographing in a case where DBPF is used instead of an infrared cut filter. An imaging sensor includes a color filter, and DBPH that has a transmission characteristic in a visible-light band, blocking characteristic in a first wavelength band adjacent to a long-wavelength side of the visible-light band, and transmission characteristic in a second wavelength band that is a part of the first wavelength band. A signal processing unit subtracts an infrared signal, which is output from an infrared pixel, from each color signal output from a pixel in each color of visible light in the imaging sensor. Here, in a case where each color signal reaches a pixel saturation level, control of performing correction in such a manner that an infrared signal subtracted from each color signal is lowered is performed.
