Embodiment 1

[0022] figure 1 It is a figure which shows an example of embodiment of this invention.

[0023] The imaging device of this embodiment has: a lens 101, which makes the visible light / non-visible light from the object to be photographed form an image at a predetermined focal length; Perform photoelectric conversion, and output a plurality of pixel signals corresponding to predetermined wavelength components; the demosaic processing unit 103 performs demosaic processing on the pixel signals from the imaging element 102; The pixel signal for the visible light component is subjected to arithmetic processing, thereby extracting the pixel signal (visible light signal) for the visible light component; pixel signal (invisible light signal); the light source color estimation unit 106 estimates the light source color based on the pixel signal from the visible light signal generation unit 104; Gain for performing white balance correction on the visible light signal output by the visible ...

Embodiment 2

[0071] figure 2 It is a flowchart showing an example when the imaging method of the present invention is executed by a program.

[0072] This program is stored in a storage medium included in the imaging device or an information processing device capable of acquiring images, and is calculated by a control unit such as a CPU according to the program, and functions equivalent to those of the imaging device of the first embodiment can be realized by software.

[0073] In the imaging step 201 , an image of one frame is acquired using an imaging element capable of splitting and imaging light irradiated from a subject into predetermined wavelength components.

[0074] In the visible light signal / invisible light signal separation step 202, the image captured in the imaging step 201 is separated into an image signal corresponding to the visible light component (visible light signal) and an image signal corresponding to the invisible light component by performing signal processing. (...

Embodiment 3

[0083] image 3 An example of embodiment of the present invention is shown. Compared with the structure of Embodiment 1, the imaging device of Embodiment 3 further includes: a ratio calculation unit 301 for calculating the ratio of each visible light signal output from the visible light signal generation unit 104 to the invisible light signal output from the invisible light signal generation unit 105 , and output the ratio information; the image quality adjustment parameter calculation unit 302, according to the ratio information output from the ratio calculation unit 301, calculates the visible light signal and the non-visible light signal for each white balance correction output from the white adjustment unit 108 The invisible light signal output by the generator 105 and the color difference signal output from the color difference signal generator 110 perform gain adjustment gain information and output it; information, to adjust the gain of the visible light signal after wh...

Abstract

A photographing method and photographing device are provided, the photographing device comprising: a visible light signal generation unit that extracts a visible light signal from a pixel signal from an imaging element; a light source color estimation unit that estimates a color temperature of a light source based on the visible light signal; a white adjustment unit that It corrects the white balance of the visible light signal according to the estimation result; the non-visible light signal generation unit extracts the non-visible light signal from the signal from the imaging element; Visible light signals are synthesized and output.

Description

technical field [0001] The invention relates to a photographing method and a photographing device. Background technique [0002] As background art in this technical field, there is JP-A-2010-161459. In this publication, it is described that "(Problem) To provide an infrared irradiation imaging device capable of adjusting the synthesis ratio of visible light components and infrared components when imaging under low illuminance. (Solution) In the infrared hybrid imaging device, When shooting under infrared irradiation shooting conditions, the white balance is processed for each color of the shooting signal generated under the visible light shooting condition with an infrared cut filter inserted on the optical path, and a white balance shooting signal is generated. The shooting generated under the infrared irradiation shooting condition The signal is separated into a visible light component shooting signal and an infrared component shooting signal, a visible light brightness s...
