PHYSICAL INFORMATION ACQUISITION METHOD, PHYSICAL INFORMATION ACQUISITION DEVICE, AND SEMICONDUCTOR DEVICE
First Claim
1. A method, said method comprising:
- detecting a corresponding wavelength region of visible light with at least one visible light detection unit coupled to an image signal processing unit, each said visible light detection unit comprising a color filter adapted to transmit the corresponding wavelength region of visible light;
detecting a wavelength region of infrared light with at least one infrared light detection unit coupled to the image signal processing unit; and
correcting, with the signal processing unit, a first signal received from the at least one visible light detection unit by subtracting a product from said first signal, said product resulting from multiplication of a second signal received from the at least one infrared light detection unit and a predetermined coefficient factor.

Abstract
A physical information acquisition method in which a corresponding wavelength region of visible light with at least one visible light detection unit coupled to an image signal processing unit is detected, each said visible light detection unit comprising a color filter adapted to transmit the corresponding wavelength region of visible light; a wavelength region of infrared light with at least one infrared light detection unit coupled to the image signal processing unit is detected; and, with the signal processing unit, a first signal received from the at least one visible light detection unit by subtracting a product from said first signal is corrected, said product resulting from multiplication of a second signal received from the at least one infrared light detection unit and a predetermined coefficient factor.
