A satellite imaging system uses multiple cameras. For example, the incoming light from a telescope section of the satellite goes through a dichroic beam splitter, with the standard visible spectrum going to a first camera and wavelengths outside of the standard visible spectrum, such as in the infrared or coastal blue range, are sent to a second camera, allowing image data from multiple wavelength ranges to be captured simultaneously. The image data from the different wavelengths of the two cameras can then be selectively recombined. In a more general case, there is a first range of wavelengths and a second range of wavelengths.

The second color is longer in wavelength than the first color and shorter in wavelength than the third color.

The projection device has a first optical axis and configured to form a projection area, wherein a projection of the first optical axis on an X-Z plane of the projection device is perpendicular to an X-Y plane on which the projection area is formed.

Some embodiments provide a mobile device configured to guide a user, via an augmented reality (AR) interface generated by the mobile device, to capture images of the physical object using a camera of the mobile device. The mobile device may be configured to obtain boundary information indicative of a boundary enclosing the physical object (e.g., a box enclosing the physical object). The mobile device may be configured to use the boundary information to determine positions from which the user is to capture images of the physical object. The mobile device may be configured to guide the user to capture the images using the AR interface by guiding the user to each of the positions in the AR interface (e.g., by generating on or more GUI elements in the AR interface that indicate a position from which the user is to capture an image).

An image-capturing device includes: an image-capturing element in which a plurality of pixels, which have different spectral sensitivities, are arrayed in a two-dimensional matrix manner, and phase-difference detection pixels are arranged as some of the pixels; a phase-difference pixel discriminating unit that classifies the phase-difference detection pixels arranged in the image-capturing element as first pixels, which have a spectral sensitivity at which degradation of image quality is more difficult to discern for human eyes than the other spectral sensitivities, and second pixels which are the phase-difference detection pixels other than the first pixels; and a phase-difference pixel value correcting unit that subjects the first pixels classified by the phase-difference pixel discriminating unit to correction processing of a lower precision than that for the second pixels.

Manufacture of an imaging element in which light entering a pixel without being transmitted through a color filter arranged in the pixel is attenuated is simplified. An imaging element includes a pixel and an incident light attenuating section. The pixel includes a color filter through which light having a predetermined wavelength of light from a subject is transmitted, and a photoelectric conversion section generating charges responding to the light transmitted through the color filter. The incident light attenuating section is arranged between the subject and the color filter, and attenuates the light entering the photoelectric conversion section without being transmitted through the color filter arranged in the pixel.

An image signal corresponding to infrared light is separated from an image signal corresponding to visible light, the visible light including an infrared light signal, even when imaging is performed while performing the infrared light irradiation. An exposure control unit alternately repeats a first frame in which an exposure time is set to a predetermined first exposure time and a second frame in which the exposure time is set to a second exposure time longer than the first exposure time. An infrared light irradiation control unit performs irradiation of infrared light in a predetermined infrared light irradiation period which is equal to or less than an aggregate period of the first frame and the second frame. An image signal acquisition unit acquires a first image signal which is the image signal in the first frame and a second image signal which is the image signal in the second frame. An extraction unit extracts a visible light intensity per unit time and an infrared light intensity per unit time from the first image signal and the second image signal. A generation unit generates an image signal corresponding to visible light and an image signal corresponding to the infrared light on the basis of the visible light intensity per unit time and the infrared light intensity per unit time.
