Problems solved by technology
In the stereoscopic imaging method, the distance to the subject is basically obtained from the amount of parallax between the left and right images. Therefore, if the left and right images imaged on the common image sensor cannot be separated, the amount of parallax cannot be detected, and the distance cannot be obtained. information

This imaging device includes an imaging element 40, an image forming optical system 10, a fixed mask 20 and a movable mask 30. The image forming optical system 10 forms an image of a subject 5 on theimaging element 40. The fixed mask 20 has a first to a third aperture which divide the pupil of the image forming optical system 10, a first filter which allows a first wavelength band to pass, and asecond filter FR which allows a second wavelength band, different from the first wavelength band, to pass. The movable mask 30 can move with respect to the image forming optical system 10, and has a light blocking part 34, and a fourth to a sixth aperture which, corresponding to the first to the third apertures, are provided in the light blocking part. Further, the first filter is provided in thefirst aperture. The second filter is provided in the second aperture. The third aperture is provided on the optical axis AXC of the image forming optical system 10.
Description
technical field [0001] The present invention relates to an imaging device, an endoscope device, an imaging method, and the like. Background technique [0002] Conventionally, a technique for optically measuring a three-dimensional shape is known. For example, various methods have been proposed, such as a stereo imaging method based on stereoscopic vision of left and right eyes, a phase shift method based on pattern illumination such as a sinusoidal pattern, and a TOF (Time of Flight) method based on time measurement of reflected light. [0003] The stereoscopic imaging method only needs to be a simple mechanism that makes the imaging system a stereoscopic optical system. Since it does not require a special lighting mechanism, lighting control, and high-level signal processing, it is suitable for considering the progress in miniaturization technology of today's imaging systems. Installation in small spaces. For example, there are many demands for attachment to the front end...
