A ring flash light diffusion device includes a first converter ring configured to connect to a camera lens and a diffuser adapter. The diffuser adapter can be connected to a first end of the first converter ring. It also includes a flash ring connected to the diffuser adapter at a position along the length of the diffuser adapter and a ring flash connected to the flash ring. It further includes a light diffuser connected to the diffuser adapter such that light emitted from the ring flash passes through the light diffuser.

A lighting device with an annular rectangular light that connects to the camera assembly by mechanical linkages. The annular rectangular light can connect to different components of a camera. The annular rectangular light can connect to a matte box or rods of the camera in some embodiments. The mechanical linkages allow positioning of the annular rectangular light such that it surrounds the front of a lens of the camera but does not obstruct a field of view of the lens.

The present invention relates to an optical element for use in a camera system for the inspection of passageways, a camera system for the inspection of passageways and a method of illuminating a passageway during inspection with a camera. An optical element for use in a camera system for the inspection of passageways comprises a first optical portion arranged to transmit light into a camera, a second optical portion arranged to transmit light emitted from a light source, the second optical portion located adjacent the first optical portion, and barrier means arranged to prevent light being transmitted from the second optical portion into the first optical portion.

A system for evenly-scattered adaptable subject lighting for mobile device photography, comprising a case configured to enclose and securely fasten a mobile device and an illuminating portion, the illuminating portion configured to produce light based on input received from a plurality of sensors. The system further comprising a plurality of programming instructions stored in a memory and operating on a processor of a network-connected computing device, and configured to direct the operation of the illuminating portion comprising at least a sensor processor and an image capture device, wherein the sensor processor adjusts the illuminating portion based on preconfigured thresholds to provide evenly-scatter lighting for capturing images of subjects via the image capture device.

Provided herein are devices for enhancing the quality of photo shooting using a camera integrated into a handheld smart device, such as a smartphone. An external lighting device comprises a base plate removably securable to a mount on the smart device, a connecting structure disposed at the edge of the top surface of the base plate and a ring-like turntable rotatably connected on the base plate via the connecting structure and a plurality of LED lights on the top surface of the turntable. When secured on the body of the smart device, the ring-like turntable rotates to a position where the LED lights surround the cameras to provide adjustable lighting. Further provided is a handheld camera system comprising a smart device, the external lighting device as described above and a protective case with a mount to attached to the lighting device.

A device includes a light-emitting device (LED) having at least two vertical light-emitting sides, and a ring-shaped light guide having a bottom side, a top side comprising a light-emitting surface, an inner sidewall, and an outer sidewall defining an indentation having at least two vertical in-coupling surfaces mated to the at least two vertical light-emitting sides of the LED.

The proposed apparatus, which functions to capture insects for research purposes, incorporates a mesh platform used to gather insects, at least one funnel used to direct insects to the mesh platform, a fan positioned at the base of the apparatus to create a down draft in the air flow which forces insects to gather on the mesh platform. A camera placed above the mesh platform and funnel to collect images of the insects on the mesh platform.

A lighting device with an annular rectangular light that connects to the camera assembly by mechanical linkages. The annular rectangular light can connect to different components of a camera. The annular rectangular light can connect to a matte box or rods of the camera in some embodiments. The mechanical linkages allow positioning of the annular rectangular light such that it surrounds the front of a lens of the camera but does not obstruct a field of view of the lens.

A method for parameterizing a machine-vision device. The method incudes the e following successive steps: a) selecting, depending on the zone of interest, a slaved lighting configuration, and recording the slaved lighting configuration in the control interface and/or applying the slaved lighting configuration; b) independently of step a), selecting an origin lighting configuration, and applying the origin lighting configuration; c) establishing an informational relationship between said origin and slaved lighting configurations and recording said relationship in the control interface so that the electronic unit commands the zone of interest to be lit in the slaved lighting configuration in response to an origin lighting configuration.
