An electronic device may contain a camera, a camera flash, and a display in a housing. The camera flash or the display may provide illumination while capturing images with camera. The camera flash may be formed from light guiding structures that receive camera flash light from a light source. The camera flash may be located under a speaker port mesh. A speaker port may contain a camera and a camera flash. Light guiding structures may have a ring shape with an opening. A speaker port, camera, or button may be located within the opening. A button may have an opaque portion in which a transparent light guiding structure for a camera flash is embedded. Camera flash structures may produce camera flash light to capture images and can serve as a status indicator to indicate when a message is received or other state change is detected during operation.

Borehole inspection device for inspecting a borehole in a workpiece has a measuring head which includes an endoscope and is insertable into the borehole to be inspected and movable relative to the borehole in different axial positions. Borehole inspection device has an imaging optics with a panoramic view for imaging the inner surface of the borehole, and the imaging optics is in image transmission connection with a digital image recorder. Device has a memory for storing the images recorded in different axial positions of the measuring head, and an evaluation apparatus for evaluating the images stored in the memory. In order to obtain surface depth information about the inner surface of the borehole, the evaluation apparatus is configured for evaluating images recorded at different viewing angles of the imaging optics with regard to the particular surface location, using a 3D reconstruction method.

A microlens array comprises an array of microlenses on a flat base. A spacer located along the periphery of the microlens array protrudes away from the plane of the base. The microlens array may be arranged in combination with one or more LEDs or pcLEDs with the spacer positioned between the microlens array and the LEDs or pcLEDs and thus spacing the microlenses away from the LED or pcLEDs. Arranged in this manner, the surface of the microlens array facing the LEDs or pcLEDs and light emitting surfaces of the LEDs or pcLEDs together define an air filled or evacuated gap between the microlens array and the LEDs or pcLEDs, which improves the performance of the microlens array in collimating or partially collimating light emitted by the LEDs or pcLEDs.

An image capturing device includes a base, a light sensing element, an image capturing lens, and multiple light sources. The light sensing element is disposed on the base. The image capturing lens is disposed above the light sensing element. The light sources are disposed on the base and arranged beside the image capturing lens. Each of the light sources emits a light beam. A chief ray direction of the light beam has a horizontal component and a vertical component. The horizontal component and the vertical component are both greater than zero.

A method for operating a portable photo booth, wherein the portable photo booth comprises a housing, a camera, and a light-emitting diode array which comprises a plurality of individually controllable light-emitting diodes, wherein the light-emitting diode array is controlled according to a control instruction in such a way that the light-emitting diode array at least temporarily assumes a lighting state in which the brightness of at least one first light-emitting diode of the light-emitting diodes differs from the brightness of at least one second light-emitting diode of the light-emitting diodes. The invention also relates to a portable photo booth.

A camera unit is housed and attached in an internal space of a pillar, the camera unit including a plurality of modules that executes respective functions regarding camera imaging, and a housing having a dimension in such a manner that an outer shape of the housing around a longitudinal direction of the housing is accommodated in the internal space, the modules being mounted on the housing without protruding from the outer shape.

The present invention relates to a dome camera with an IR diffuse reflection prevention function to efficiently prevent infrared (IR) light from being diffusely reflected on an inner circumference of a dome cover and being incident on a lens module and prevent a surveillance direction of the lens module from being changed or an IR diffuse reflection prevention bushing from being deformed by reducing a frictional force between the inner circumference of the dome cover and a front side of the IR diffuse reflection prevention bushing when the dome cover is mounted.

A camera with a simple and compact structure can emit light using a discharge tube. A camera includes a circuit board including a contact connected to a trigger coil, a discharge tube that can discharge electricity, a housing accommodating the discharge tube, a reflector being conductive, urged toward the housing, and attached to the housing, and a wire having an end electrically connected to the contact on the circuit board and a distal end with an exposed conductor. The housing is attached to the circuit board. The housing includes a receiving portion receiving the reflector, and a sidewall located lateral to the receiving portion and extending perpendicular to the circuit board. The sidewall of the housing has a cutout guiding the wire inside the housing and holding the wire to have the distal end of the wire held between the reflector and the receiving portion.
