摘要:
A method according to embodiments of the invention includes, for a field of view comprising a plurality of portions, determining an amount of light for each portion. LEDs corresponding to each portion are selectively energized over a plurality of time periods, such that a sum of illumination generated by each LED during the plurality of time periods equals the determined amount of light. An image of the field of view is captured, for example by a camera.

A lighting system adapted for use with a rolling shutter imagers. The system uniquely provides PWM-control of a light source in the context of an imager with a "rolling- shutter"-type exposure architecture that operates on a line-by-line basis rather than a frame -by- frame basis. The preferred embodiment comprises a lamp such as a LED, a drive circuit coupled to the lamp capable of energizing the lamp for switching the lamp on and off, and a lamp control circuit coupled to the drive circuit with a means for receiving a line timing signal from an imaging system, the lamp control circuit synchronously energizing the lamp with the line timing signal via the drive circuit, the line timing signal being based upon the horizontal line rate of the imager.

A method (460) for illuminating a target (20) with one or more lighting effects using a networked light source. An image recording device (16) comprising a wireless communications module (36) identifies any lighting units (10) located within a first distance (50) to the image recording device, and communicates, via the wireless communications module, a request to one or more of the identified lighting units to illuminate the target with one or more of a plurality of lighting effects when the image recording device captures an image or records a video.

A medical image formation apparatus (100) includes laser emitting elements (1) - (7) which emit laser light rays different in wavelength, an image selection unit (9) to select a kind of observation image, a light source control unit (8) which controls the lighting of the laser emitting elements (1) - (7) in accordance with an observation mode corresponding to a combination of the selected observation images, an imaging unit (18) which images return light ray of the laser light ray from an observation target and then outputs the return light ray as an image signal, and an image signal processing circuit (24) which forms the observation images from the image signal from the imaging unit. The light source control unit (8) turns on at least one of the laser emitting element (1) to (7) when the kind of selected observation image is a first observation image, and turns on at least one of the laser emitting elements in case where the first observation image is selected when the kind of selected observation image is a second observation image.
摘要:
A three-dimensional imaging system to reduce detected ambient light comprises a wavelength stabilized laser diode to project imaging light onto a scene, an optical bandpass filter, and a camera to receive imaging light reflected from the scene and through the optical bandpass filter, the camera configured to use the received imaging light for generating a depth map of the scene.
摘要:
Es wird ein Fotoautomat (1) und eine Vorrichtung (2) zur Aufnahme eines omnidirektionalen Bilds mit einem omnidirektionalen Bildsystem (3) und mit mindestens einem, ein omnidirektionales Blitzlicht (9) erzeugendes Blitzgerät (7, 24, 27, 33) gezeigt, das wenigstens ein Leuchtmittel (8) aufweist. Um eine hohe Bildqualität bei einem Panoramabild mit einem Portrait im Vordergrund ermöglichen zu können, wird vorgeschlagen, dass das Blitzgerät (7, 24, 27, 33) zur Erzeugung des omnidirektionales Blitzlichts (9) einen für das Leuchtmittel (8) bzw. einen für die Leuchtmittel (8) gemeinsam vorgesehenen Reflektor (10) aufweist, über den sich wenigstens ein Teil des Blitzlichts (9) reflektiert.
摘要:
A light-emitting apparatus and a camera system including the same are disclosed. According to an aspect of the invention, a camera system is provided that includes a light source color detector for detecting a color temperature of a light source; an auxiliary light apparatus for changing a color temperature of auxiliary light according to the detected color temperature of the light source; and a white balance controller for adjusting white balance while the auxiliary light is being radiated. Accordingly, a photograph having a natural color sense can be reproduced by reducing a sense of color incongruity in a captured image.
