Color night vision cameras, systems, and methods thereof

Disclosed are improved methods, systems and devices for color night vision that reduce the number of intensifiers and/or decrease noise. In some embodiments, color night vision is provided in system in which multiple spectral bands are maintained, filtered separately, and then recombined in a unique three-lens-filtering setup. An illustrative four-camera night vision system is unique in that its first three cameras separately filter different bands using a subtractive Cyan, Magenta and Yellow (CMY) color filtering-process, while its fourth camera is used to sense either additional IR illuminators or a luminance channel to increase brightness. In some embodiments, the color night vision is implemented to distinguish details of an image in low light. The unique application of the three-lens subtractive CMY filtering allows for better photon scavenging and preservation of important color information.

ENDOSCOPE AND ENDOSCOPE SYSTEM

An endoscope includes a four color separation prism having a first color separation prism, a second color separation prism, a third color separation prism, and a fourth color separation prism which respectively separate light incident from an affected area into a blue, red and green color components, and an IR component, first, second, third and fourth color image sensors, and a signal output. The first color separation prism, the second color separation prism, the third color separation prism, and the fourth color separation prism are sequentially disposed from an object side when receiving the light incident from the affected area. The first color image sensor is disposed opposite to the second color image sensor and the third color image sensor across an incident ray which is incident vertically to an object side incident surface of the first color separation prism.

Camera systems for motion capture

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.

Image capture unit and method with an extended depth of field

In a minimally invasive surgical system, an image capture unit includes a prism assembly and sensor assembly. The prism assembly includes a beam splitter, while the sensor assembly includes coplanar image capture sensors. Each of the coplanar image capture sensors has a common front end optical structure, e.g., the optical structure distal to the image capture unit is the same for each of the sensors. A controller enhances images acquired by the coplanar image capture sensors. The enhanced images may include (a) visible images with enhanced feature definition, in which a particular feature in the scene is emphasized to the operator of minimally invasive surgical system; (b) images having increased image apparent resolution; (c) images having increased dynamic range; (d) images displayed in a way based on a pixel color component vector having three or more color components; and (e) images having extended depth of field.

Imaging apparatus

There is provided an imaging apparatus including a first imaging element and a second imaging element configured to perform imaging in the same direction. The second imaging element is different in pixel arrangement between a central part and a non-central part, such that the pixels in the non-central part are more sensitive than the pixels in the central part. Image signals from the non-central part of the second imaging element are used to correct for shading (vignetting) in image signals from the first imaging element.

An image fusing method includes converting a first image into a first intermediate image, converting a second image into a second intermediate image including a plurality of components, fusing one of the plurality of components of the second intermediate image with the first intermediate image to obtain a fused component, and combining the fused component and other ones of the plurality of components of the second intermediate image to obtain a target image.

Multimodal image sensing for region of interest capture

An imaging sensor system includes a control system that helps save energy, computing, and communication resources by capturing evaluation images with a gating image sensor and processing the evaluation images to determine whether there is a region of interest (ROI) present that warrants capturing a subsequent image with a gated image sensor for additional image processing. That is, the gating image sensor and preliminary processing operates as a gate for turning on the gated sensor for the additional image capturing and processing. The additional image captured by the gated sensor may include only the ROI, which is provided to an image processing algorithm for further image processing. In addition, a gating sensor may include infrared sensing to help determine whether the ROI includes thermal data indicative of human features.
