- an imaging device 10 according to an embodiment of the present disclosure is configured with an imaging optical system 11 and an imaging device 12 .
- the imaging device 10 may further include a controller 13 .
- the first optical member 111 has a lens 113 with a semi-transmissive reflecting surface 111a and an opening (region R) on the image side.
- Lens 113 is transparent, but is not limited to being transparent.
- the lens 113 is a so-called donut lens.
- the region R is not limited to an aperture as long as it does not block the light from the secondary mirror of the Cassegrain optical system to the imaging device 12 .
- the lens 113 may include, for example, a lens having a curvature different from that of other portions in the region R, or may include a transparent plate, a filter, or the like in the region R.
- the subject light flux corresponding to the telephoto image reaches the imaging element 12 through the optical paths L1 and L2, and at the same time, the subject light flux corresponding to the wide-angle image also reaches the imaging element 12 through the optical path L0. Then, a plurality of images on the light receiving surface 12a, that is, an image formed via the Cassegrain optical system and an image formed via the lens 113 without passing through the second optical member 112, which is a secondary mirror, imaged. In other words, a plurality of images with different focal lengths are formed on the same light receiving surface 12a of the imaging element 12.
- the controller 13 separates the superimposed image olim into a telephoto image im1 and a wide-angle image im2 by image processing.
- the controller 13 separates the superimposed image olim by applying image processing methods such as independent component analysis, wavelet method, and image separation model.
- the image separation model is, for example, a model constructed by creating a superimposed image by superimposing a plurality of images in advance and subjecting the superimposed image to machine learning using the plurality of images as correct answers.
- a generator that generates images like the Encoder-Decoder model competes with a discriminator that determines whether the generated image is a fake image, and a Pix-to model that generates a pair of images that reflects the relationship between them. - It may be a model to which Pix is applied.
- a storage unit is one or more memories.
- the memory is, for example, a semiconductor memory, a magnetic memory, or the like, but is not limited to these, and can be any memory.
- the storage unit may be built in the controller 13 or may be provided outside the controller 13, for example.
- the controller 13 separates the telephoto image im1 by extracting components determined to be the telephoto image im1 using the image separation model from the image signal of the superimposed image olim (step S2).
- the controller 13 separates the wide-angle image im2 by subtracting the component of the telephoto image im1 from the image signal of the superimposed image olim (step S3).
- the dichroic coated mirror provided on the reflecting surface 111a reflects the G component of RGB
- the antireflection film provided on the image-side surface of the lens 113 transmits the R component and the B component with high transmittance.
- an image corresponding to the telephoto image im1 having G components and an image corresponding to the wide-angle image im2 having R and B components are superimposed and formed on the light receiving surface 12a.
- the antireflection film transmits only one of the R component and the B component with a high transmittance, and the telephoto image im1 having the G component and the wide-angle image im2 having only one of the R component and the B component are superimposed.
- FIG. 5 is a cross-sectional view illustrating another configuration of the imaging device 10. As shown in FIG. In FIG. 5, the same components as in FIG. 2 are given the same reference numerals. An imaging apparatus 10 according to this modification includes the same components as those of the above-described embodiment, but as shown in FIG. have.
- the imaging optical system 11 of the imaging device 10 at least part of the reflecting surface 111a of the first optical member 111 and the reflecting surface 112a of the second optical member 112 face each other, and the first A second optical member 112 is provided closer to the object side than the optical member 111 of the second optical member 111 .
- the region R may be an aperture as shown in FIG.
- a plurality of images formed on the light-receiving surface 12a are formed by the images transmitted through the first optical member 111 and formed by the reflecting surface 111a of the first optical member 111 and the reflecting surface 112a of the second optical member 112. and an image formed by reflection.
- f1 in FIG. 5 is the focal length of the lens 113 provided on the image side of the first optical member 111 .
- the imaging apparatus 10 can obtain a telephoto image and a wide-angle image with high resolution by the above configuration.
- the image processing by the controller 13 is the same as in the above embodiment.

Embodiments of the present disclosure extend to all novel features or combinations thereof described in the present disclosure or to all novel method or process steps or combinations thereof described. be able to.
- Descriptions such as “first” and “second” in this disclosure are identifiers for distinguishing the configurations. Configurations that are differentiated in descriptions such as “first” and “second” in this disclosure may interchange the numbers in that configuration. The exchange of identifiers is done simultaneously. The configurations are still distinct after the exchange of identifiers. Identifiers may be deleted. Configurations from which identifiers have been deleted are distinguished by codes. The description of identifiers such as “first” and “second” in this disclosure should not be used as a basis for interpreting the order of the configuration or the existence of lower numbered identifiers.
