Abstract
An image capturing apparatus comprises an image sensor that receives beams of reflected light from a subject incident via an imaging optical system whose wavelength that reaches a light-receiving surface is different in accordance with an angle of incidence of reflected light, and generates an image signal. The apparatus changes a state of the imaging optical system or the image sensor such that a second image signal is generated by beams for which the angle of incidence of the reflected light from the imaging optical system is different from the beams by which a first image signal is generated. The apparatus outputs a spectral image based on a plurality of the image signals generated by receiving the beams in different state of the imaging optical system or the image sensor.
Claims22
An image capturing apparatus comprising:
- an image sensor configured to receive beams of reflected light from a subject incident via an imaging optical system whose wavelength that reaches a light-receiving surface is different in accordance with an angle of incidence of reflected light, and generate an image signal;
- one or more processors;
- and
- a memory configured to store instructions which, when the instructions are executed by the one or more processors, cause the image capturing apparatus to function as:
- a control unit that changes a state of the imaging optical system or the image sensor such that a second image signal is generated by beams for which the angle of incidence of the reflected light from the imaging optical system is different from the beams by which a first image signal is generated;
- and
- an output unit that outputs a spectral image based on a plurality of the image signals generated by receiving the beams in each state of the imaging optical system or the image sensor changed by the control unit.
A method of controlling an image capturing apparatus that includes an image sensor operable to receive beams whose wavelength that reaches a light-receiving surface is different in accordance with an angle of incidence of reflected light among the reflected light from a subject incident via an imaging optical system, and generate an image signal, the method comprising:
- controlling to change a state of the imaging optical system or the image sensor such that a second image signal is generated by beams whose angle of incidence of the reflected light from the imaging optical system is different from beams by which a first image signal is generated;
- and
- outputting a spectral image based on a plurality of the image signals generated by receiving the beams in each state of the imaging optical system or the image sensor changed by the control unit.
A non-transitory computer-readable storage medium comprising instructions for performing a method of controlling an image capturing apparatus that includes an image sensor operable to receive beams whose wavelength that reaches a light-receiving surface is different in accordance with an angle of incidence of reflected light among the reflected light from a subject incident via an imaging optical system, and generate an image signal, the method comprising:
- controlling to change a state of the imaging optical system or the image sensor such that a second image signal is generated by beams whose angle of incidence of the reflected light from the imaging optical system is different from beams by which a first image signal is generated;
- and
- outputting a spectral image based on a plurality of the image signals generated by receiving the beams in each state of the imaging optical system or the image sensor changed by the control unit.
