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.

Claim (Index 1):
An imaging processing device comprising:\n an imaging sensor in which a plurality light-receiving elements are arranged; a filter for transmitting at least a part of a visible light and at least a part of an infrared light, in which: i) a plurality of kinds of filter regions are arranged in a predetermined array corresponding to an arrangement of the plurality of light receiving elements of the imaging sensor and have different transmission characteristics corresponding to wavelengths in a visible-light band; ii) at least some of the plurality of kinds of filter regions each having an infrared-light transmission wavelength band to transmit a light on a longer wavelength side than the visible-light band, in a manner substantially similar to each other; and iii) a light-blocking wavelength band for blocking a light is provided between the visible-light band and the infrared-light transmission wavelength band; an optical system including a lens that forms an image on the imaging sensor; and a signal processing device comprising a processor which performs a signal removal process for removing an infrared light component from a sensor signal containing a visible light component and an infrared light component so as to produce a visible image signal, said sensor signal being outputted from the imaging sensor; wherein the signal processing device, when the sensor signal reaches a pixel saturation level of the imaging sensor, operates to reduce a value of the sensor signal processed in the signal removal process to a predetermined value lower than the pixel saturation level.
