The present disclosure generally relates to hyperspectral spectroscopy, and in particular, to systems, methods and devices enabling a single-sensor hyperspectral imaging device. Hyperspectral (also known as “multispectral”) spectroscopy is an imaging technique that integrates multiples images of an object resolved at different narrow spectral bands (i.e., narrow ranges of wavelengths) into a single data structure, referred to as a three-dimensional hyperspectral data cube. Data provided by hyperspectral spectroscopy allow for the identification of individual components of a complex composition through the recognition of spectral signatures of individual components within the three-dimensional hyperspectral data cube.

Scopes such as medical imaging camera head devices and methods are provided using light captured by an endoscope system or other medical scope or borescope. At least one polarizing optical element manipulates the polarization properties of image light. The manipulated image light is focused on an image sensor including polarizers for each pixel. Multiple images are produced based sets of pixels having the same orientation of polarizer. The resulting images are combined with high dynamic range techniques.

An image capture apparatus detects a subject in a captured image. The image capture apparatus further recognizes its user based on an eyeball image of the user. The image capture apparatus then selects a main subject area from among the detected subject areas, based on information regarding subjects captured in the past and stored being associated with the recognized user.

A camera is usable to observe a switched position of a switch contact of a switchgear apparatus. In an embodiment, the camera includes a light source to illuminate the switch contact, an image sensor, and a lens to focus light beams emanating from the switch contact onto the image sensor. In an embodiment, the camera additionally includes an elastic light protection cap to seal off a beam path, from the lens to the image sensor, from the light source in a lightproof manner.

An image sensor assembly includes at least one upconverter configured to detect light in a NIR waveband that is received from an object to be imaged and generate, based on the detected light, upconverted light that is outside of the NIR waveband; and at least one image sensor configured to detect the upconverted light.

This application discloses a photographing apparatus and method, and relates to the field of image processing. When a high-quality image in a low illumination environment is obtained, costs are reduced, a size is reduced, and product compatibility is improved. The method includes: controlling a light filtering unit to: transparently transmit visible light in incident light and block infrared light in the incident light in a first image exposure interval, transparently transmit the infrared light in the incident light in a first time period of a second image exposure interval, and block the incident light in a second time period of the second image exposure interval; performing, by using an image sensor to obtain a first image, and performing photoelectric imaging on a light ray to obtain a second image; and synthesizing the first image and the second image, to generate a first target image.

An apparatus includes a control unit that executes exposure control by adjusting a shutter speed, an aperture value, and a sensitivity, and a setting unit that switches on/off a simulation function for adjusting an image quality of an image for live view display to match an image quality depending on an aperture opening for acquiring a still image for recording. If the simulation function is on, the control unit controls a difference amount between an aperture value for acquiring the image for live view display and an aperture value for acquiring the still image depending on an aperture value for acquiring the still image for recording such that the difference amount when the aperture value for the still image is a second value larger than a first value is larger than that when the aperture value for the still image is the first value.

An optical redirection adapter for an electronic device having a camera includes a housing. An optical element is attached to the housing and positioned such that, when the adapter is attached the electronic device, the optical element is positioned in the camera's field of view. The optical element reflects light in the camera's field of view from a redirection angle that is offset from the camera's field of view. The optical redirection adapter facilitates ergonomically sound use of the camera.

An EO/IR optical imaging system comprises collection optics to collect light from a scene into a collimated or near-collimated space. An imaging detector is positioned at the image plane and configured to integrate incident light (radiant flux or photons) over an image frame and readout a sequence of pixelated images at a frame rate, said detector exhibiting a saturation threshold. To prevent saturation of the imaging detector, a MEMS MMA is positioned in the collimated or near-collimated space. A secondary detector (via a pick-off) samples light from the collimated or near-collimated space multiple times per image frame. A controller responsive to the sampled light commands a percentage of the mirrors to re-direct light incident on those mirrors to a light dump and commands the remaining mirrors to re-direct light incident on those mirrors to the imaging detector. Together the mirrors adjust a fraction of light reaching the imaging detector such that the integrated incident light for a given image frame is less than the saturation threshold.

An image sensor having a brightness self-adjust capability is provided. The image sensor can include a light adjustment layer made of adaptive optical materials and a set of pixels. The image sensor can also include a control circuit configured to generate control signals to control adjustment of one or more light transparency levels at the set of pixels on the light adjustment layer based on the light intensity distribution. The image sensor can further include a sensor array configured to receive lights and facilitate output of image and/or video signals based on the received lights. For facilitating light adjustment, the control circuit can be configured to obtain light intensity distribution from a pre-sensor or the sensor array.
