A camera system with a multispectral sensor that can be used in combination with a flash to determine a spectrum of the ambient illumination without needing a separate measurement. This may then be used to colour-correct an image captured with or without flash.

Provided are a spectral filter, and an image sensor and an electronic device including the spectral filter. The spectral filter includes: a first metal reflective layer; a second metal reflective layer provided above the first metal reflective layer; a plurality of cavities provided between the first and second metal reflective layers, the plurality of cavities including first patterns corresponding to different center wavelengths; and a plurality of lower pattern films provided below the first metal reflective layers, the plurality of lower pattern films including second patterns corresponding to the different center wavelengths.

Embodiments of the disclosure provide systems and methods for motion capture to generate content (e.g., motion pictures, television programming, videos, etc.). An actor or other performing being can have multiple markers on his or her face that are essentially invisible to the human eye, but that can be clearly captured by camera systems of the present disclosure. Embodiments can capture the performance using two different camera systems, each of which can observe the same performance but capture different images of that performance. For instance, a first camera system can capture the performance within a first light wavelength spectrum (e.g., visible light spectrum), and a second camera system can simultaneously capture the performance in a second light wavelength spectrum different from the first spectrum (e.g., invisible light spectrum such as the IR light spectrum). The images captured by the first and second camera systems can be combined to generate content.

According to the invention, an image sensor is disclosed. The image sensor may include a plurality of pixels. Each pixel of a first portion of the plurality of pixels may include a near-infrared filter configured to block red, green, and blue light; and pass near-infrared light. Each pixel of a second portion of the plurality of pixels may be configured to receive at least one of red, green, or blue light; and receive near-infrared light.

Driving an emitter to emit pulses of electromagnetic radiation according to a jitter specification in a hyperspectral, fluorescence, and laser mapping imaging system is described. A system includes an emitter for emitting pulses of electromagnetic radiation and an image sensor comprising a pixel array for sensing reflected electromagnetic radiation. The system includes a driver for driving emissions by the emitter according to a jitter specification. The system is h that at least a portion of the pulses of electromagnetic radiation emitted by the emitter comprises one or more of a hyperspectral emission, a fluorescence emission, and/or a laser mapping pattern.

An image sensor includes a plurality of non-color pixel sensors each configured to sense a non-color signal; and a color pixel sensing region including at least one color pixel sensor configured to sense a color signal, wherein the color pixel sensing region has an area physically greater than an area of each of the non-color pixel sensors.

The invention relates to an image acquisition device comprising a sensor composed of an array of photosensitive pixels, and an array of elementary filters covering the sensor. Pixels may be of three different types: panchromatic pixels, primary colour pixels and infrared pixels. Under low illumination conditions, the device displays a monochrome image using panchromatic pixels, and under high illumination conditions, a colour image with a high signal to noise ratio, by combining primary colour images and subtracting the infrared image.

An imaging device includes: an imaging sensor; a color filter including first band filters and a second band filter configured to transmit narrowband light having a maximum value of a transmission spectrum outside a range of the wavelength band of the light that passes through each first band filter; a first light source unit; a second light source unit configured to radiate light having an upward projecting distribution of a wavelength spectrum in relation to intensity and having a narrowband light spectrum narrower than the broadband; and a control unit configured to cause the first light source unit and the second light source unit to radiate the beams of light simultaneously, wherein a peak wavelength of the light radiated by the second light source unit is an infrared region or a near-infrared region.

There is provided an image sensor including a pixel unit, the pixel unit including a photodiode, a first color filter and a second color filter each disposed in a different position on a plane above the photodiode, and a first on-chip lens disposed over the first color filter and a second on-chip lens disposed over the second color filter.
