A cannula with a proximally mounted camera and proximally mounted light sources. The lighting sources have beam axes directed distally, toward a workspace at the distal end of the cannula. The light sources are coupled with focusing lenses, to reduce the beam angle of the lighting sources and reduce glare within the cannula tube.

A portable remote controlled video production apparatus and method are provided, as is a teleprompter/Interrotron integrated with a camera. A computer is mounted in a rigid cage, the computer having a local portion of remote access remote control software. A camera is fixedly mounted in the cage in communication with the computer; either the camera or the computer have camera control software running thereon. A monitor is fixedly mounted in the cage in front of the camera and parallel to the lens axis; the monitor is in communication with the computer. A beamsplitter is fixedly mounted in the cage in front of the lens reflecting light from the monitor towards a front of the cage. The camera and computer are controllable remotely via a remote portion of the remote access remote control software running on a remote computer communicating with the local portion of the remote access remote control software.

An off-axis light-emitting device and an image capturing module using the same are provided. The off-axis light-emitting device includes a substrate, a light-emitting chip, and an optical element. The substrate has a mounting surface, and the light-emitting chip for generating a light beam has a light output surface. The light-emitting chip is disposed on the assembly surface. The optical element is disposed on the assembly surface and includes a dome portion. The dome portion is arranged in an optical path of the light beam and extends in a first direction to form an elongated shape. The dome portion has a first reference plane that passes through two opposite side surfaces of the dome portion, and the first reference plane is offset from a geometric center of the light-emitting chip in a second direction, so that the light beam passing through the dome portion forms an off-axis projection light.

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.

A tubular video camera assembly for recording photos or video includes a tube which is comprised of a rigid material such that the tube can be gripped by a user. A camera is disposed on an end of the tube to capture imagery in the direction that the tube is pointed. A plurality of first light emitters is disposed on the end of the tube to emit infrared light to facilitate the camera to capture imagery in a darkened environment. A plurality of second light emitters is disposed on the end of the tube to emit light visible light to illuminate a darkened area. A laser light emitter is disposed on the end of the tube to emit a beam of laser light outwardly from the tube for indicating a target of the camera.

Various embodiments disclosed herein include adaptive light source modules that can provide adaptive illumination to a scene. The adaptive light source modules may comprise a housing, an emitter array, and a lens. The emitter array comprises a plurality of emitters. The lens may redirect light emitted from the emitter array through a transparent window of the housing. The housing may further include a prismatic surface that distorts light emitted from the emitter array and/or one or more non-transparent portions that limits light travelling therethrough. The adaptive light source module may optionally comprise a light sensor, and a portion of the lens may be configured to direct light toward the light sensor.

A light-emitting device includes: a light-emitting unit having a light-emitting surface; a light guide member configured to guide incident light from the light-emitting unit, the light guide member including: a total reflection portion configured to reflect the incident light from the light-emitting unit, and a Fresnel lens portion where light reflected by the total reflection portion is incident; and a movement mechanism configured to move the light guide member relative to the light-emitting unit in a direction that intersects a center axis of the light-emitting surface.

Disclosed according to an embodiment of the present invention is a camera module, comprising: a light source; an optical unit which converts light, output by the light source, into a planar form or a multi-point form and outputs same; and an image sensor, wherein the light source is periodically turned on/off, and when the light source is turned on, the optical unit moves to be positioned in a first position, and when the light source is turned off, the optical unit moves to the initial position thereof.

Introduced here are computer programs and associated computer-implemented techniques for determining reflectance of an image on a per-pixel basis. More specifically, a characterization module can initially acquire a first data set generated by a multi-channel light source and a second data set generated by a multi-channel image sensor. The first data set may specify the illuminance of each color channel of the multi-channel light source (which is configured to produce a flash), while the second data set may specify the response of each sensor channel of the multi-channel image sensor (which is configured to capture an image in conjunction with the flash). Thus, the characterization module may determine reflectance based on illuminance and sensor response. The characterization module may also be configured to determine illuminance based on reflectance and sensor response, or determine sensor response based on illuminance and reflectance.

A light source device includes: a light-shielding member defining an opening; a light-guide member located in the opening in a top view and including two or more divided lens portions; and a plurality of light-emitting parts disposed such that each of the plurality of light-emitting parts corresponds to a respective one of the lens portions, each of the plurality of light-emitting parts being configured to be individually turned on. Each of the light-emitting parts has an upper surface serving as a light-emitting surface. The two or more lens portions are Fresnel lenses. Irradiation areas corresponding to the light-emitting parts are at least partially different from each other.
