An image processing system and a setting method capable of performing lighting setting of illumination in a simpler manner are provided. The control device (100) evaluates evaluation lighting patterns (xi) one by one to calculate evaluation values (Pi), and uses coefficients (1i) determined based on the evaluation values (Pi) to linearly combine each evaluation lighting pattern (xi) to determine a lighting pattern for measurement (L).

A low-glare fluorescent-powder LED light device includes a shell, a multi-frequency directional light source, a high-frequency directional light source, and an electrical control circuit. The shell has a surrounding wall, which defines a front opening and a rear opening and has an inner surface extending along a central axis. The multi-frequency directional light source, including at least one fluorescent-powder LED, is disposed at the inner surface of the shell. The high-frequency directional light source, including a plurality of high-frequency LEDs, is disposed at the inner surface of the shell such that the high-frequency LEDs are arranged in radial symmetry about the central axis. The electrical control circuit can drive the multi-frequency directional light source and/or the high-frequency directional light source. The central light beams emitting from the high-frequency LEDs do not reach the fluorescent-powder LED, so that the fluorescence interference of the fluorescent-powder LED can be avoided.

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.

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.

There is provided an attachment for an illumination device which can change a ring-shaped illumination device to a dome-shaped illumination device. An attachment for dome illumination includes: a dome member made of a material that transmits and diffuses light emitted from a light emitting opening section of the ring-shaped illumination device inwardly; a plate member connected to the dome member, and connected to a main case so as not to form a gap when the attachment for dome illumination is fitted to the ring-shaped illumination device; and a dome cover which holds the dome member and the plate member so as to shield the space formed by the dome member, the plate member, and the light emitting opening section from light when the attachment for dome illumination is fitted to the ring-shaped illumination device.

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 photography system provides a photography station which can be conveniently set up and provides consistent quality of photographs regardless of ambient conditions. The system includes a digital camera, a ring flash, and a tent providing a subject space for arranging the subject during photography. The tent is configured to surround the subject to at least partially isolate the subject from the surroundings. The system further includes a background unit arranged within the tent to allow for subsequent background replacement processing.
