A light source device includes: a plurality of light source parts configured to emit light. Each of the light source parts comprises a light-emitting element and a light guiding member. the plurality of light-emitting elements are configured to emit light passing through the light guiding members from the light source parts in an array in an irradiated region. One or more of the plurality of light source parts are arranged in a placement region in a different arrangement from an arrangement of the light in the irradiated region.

Introduced here are light sources for flash photography configured to produce high-fidelity white light that is tunable over a broader range of correlated color temperatures (CCTs) than conventional flash technologies. The light source can include multiple independently controllable color channels representing illuminants (e.g., light-emitting diodes) of different colors with varying degrees of saturation. Operating collectively, the multiple color channels can produce a high spectral quality white light corresponding to different CCTs (e.g., “warm” white light having a red hue, “cool” white light having a blue hue). Operating independently, these same color channels can be pre-flashed in a variety of prescribed sequences to probe the spectral characteristics of a scene, thereby allowing for an enhanced, spectrally matched white flash as well as collecting per-pixel reflectivity data that can be later used in during post processing of the captured image.

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 channel of the multi-channel light source (which may be able to produce visible light and/or non-visible light), 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 light). 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 video recording device (video camera), a stand (magnetic support) and a wall/ceiling attachment is disclosed. The video recorder consists of a video camera with a high-quality sensor and a lens with a wide field of view. It is placed in a spherical housing with a semi-transparent stealth segment window. The video recording device is fixed on the stand using a magnetic holder, which allows one to orient and fix the video camera within 360 degrees around the vertical axis and within 0-180 degrees around the horizontal axis. The wall/ceiling mounting bracket (attachment) makes it possible to place the video camera on vertical (inner wall of the room, walls of cabinets, furniture, etc.), horizontal (ceiling of the room) and inclined surfaces of any configuration. The device is capable of video recording in insufficient and reduced illumination conditions of a room.

A flash light emitting diode (LED) package includes: a first substrate including first and second opposing surfaces; an LED device on the first surface of the first substrate and having a light emitting region; a shutter on the LED device, and configured to expose and cover the light emitting region; a second substrate on the second surface of the first substrate; and a shutter driving unit on the second substrate and configured to move the shutter. The shutter driving unit includes: a magnetic field forming unit configured to generate a magnetic field in response to application of a current, a power generation unit having a permanent magnet and configured to generate power and/or movement in response to the magnetic field, and a power transmission unit connected between the shutter and the power generation unit and configured to transmit the power and/or movement to move the shutter.

An illumination device selectively disposed on an object having a first side and a second side is provided. The illumination device comprises a light-emitting module, a camera unit and a rotation mechanism. The lighting direction of the light-emitting module points towards the front of the first side. The central filming direction of the camera unit points towards the front of the first side. The light-emitting module is coupled to the rotation mechanism such that the light-emitting module is capable of rotating about an axis of the rotation mechanism. When the lighting direction falls in a first angular range relative to the axis of the rotation mechanism, the light-emitting module provides a first mode illumination. When the lighting direction falls in a second angular range relative to the axis of the rotation mechanism, the light-emitting module provides a second mode illumination. Said first angular range is different from said second angular range. When the light-emitting module provides the second mode illumination, the central filming direction falls in the second angular range.

The present disclosure provides systems and methods for medical imaging. The system may comprise a plurality of illumination sources. The plurality of illumination sources may comprise at least two of (i) a white light source configured to generate a white light beam and (ii) one or more light emitting diodes (LEDs) or laser light sources configured to generate one or more laser light beams. The system may further comprise a movable plate comprising one or more cut-outs. The movable plate may be (i) optically aligned with one or more of the plurality of illumination sources and (ii) configured to move so as to (a) control an exposure of the one or more illumination sources through the one or more cut-outs, relative to a pre-determined frame capture rate, and (b) generate one or more light pulses based on the controlled exposure of the one or more illumination sources.

A strobe module can include a Fresnel lens that defines an external surface of the strobe module and a sidewall at least partially defining an internal volume and defining an external channel. A gasket can be disposed in the external channel. A substrate can be coupled to the sidewall to further define the internal volume and a light source can be disposed on the substrate in the internal volume.

Methods, systems, and apparatus are provided for manufacturing a flash module. In some implementations, the method includes mounting at least one LED module on a top portion of a first substrate for providing light. A lens portion is mounted on a second substrate in a first region of the second substrate. The lens portion illuminates the light from the at least one LED module and the second substrate comprises the first region having a first diameter and a second region for providing a path for the illuminating light having a second diameter. The first diameter is greater than the second diameter. The second substrate is mounted on the first substrate. A substance is applied to a top portion of the second substrate from an end of the first diameter to the end of the second diameter and to a side portion of the second substrate in the second region.
