A camera apparatus records only those objects in a surround which are situated in a predetermined object plane at a distance from the camera apparatus. To this end, the camera apparatus includes an illumination device for illuminating the desired object with an illumination light and an image capture device (for capturing the illumination light reflected by the object. For recording that is dependent on the object plane, the camera apparatus additionally comprises a control device for driving the illumination device to provide the illumination light in the form of light pulses and for controlling the image capture device to capture the reflected illumination light within recording intervals assigned to the light pulses. To avoid interference effects on a resultant image representation, provision is additionally made for a deflection unit for deflecting the respective illumination light between the surround and the illumination device and the image capture device.

A light guide device is provided. The light guide device includes a light guide member and a reflective member. The light guide member includes a junction surface, a first light incident member, a second light incident member, a contact surface, and a reflective curve surface. The reflective member includes a reflective surface adapted to the reflective curved surface and the contact surface of the light guide member. The first light receiving member and the second light receiving member respectively aligned to a first light-emitting element and a second light-emitting element, and are used to receive light emitted by the first light-emitting element and the second light-emitting element and guide the received light out.

A flash system for an electronic device includes a ring-shaped light guide having a central opening. A camera lens is positioned in or behind the opening. A first light emitting diode (“LED”) is mounted on a printed circuit board (“PCB”), and the LED and PCB are encapsulated by a molded light guide of the flash system. An identical LED and PCB are encapsulated at an opposite end of the molded light guide (i.e., 180 degrees away). The back surfaces of each PCB diffusively reflects light from the LED on the other PCB. Light extraction features on the light guide surface uniformly leak out light from the LEDs. The light emission profile of the light guide has a peak axially aligned with the central opening of the light guide and rolls off to the edge of the camera's field of view.

One aspect of the present disclosure is an imaging system including an optical sensor defining an optical axis. The system further includes a light source. The system may include an optical beam splitter, and may also include an optional diffusing lens that may be configured to diffuse and/or collimate light from the light source and direct light exiting the diffusing lens to the optical beam splitter. The optical beam splitter is configured to direct light from the light source along the optical axis of the optical sensor.

An illumination apparatus includes: a light-guiding portion including a light-introducing opening through which light is introduced from a light-emitting portion of an image pickup apparatus, a reflective surface that reflects light introduced from the light-introducing opening toward an image pickup optical axis of the image pickup apparatus, and a diffusion portion that diffuses the light reflected by the reflective surface toward an object as diffused light; and a reflective body including an opening portion allowing an image pickup opening of the image pickup apparatus to be exposed, and a reflective portion provided around the opening portion and including a reflective surface formed to expand from the opening portion toward the object, wherein the diffusion portion is disposed at a part of the reflective portion and the reflective body includes a wall portion extending to the object side at a boundary between the opening portion and the diffusion portion.
