A mobile device case for coupling around a miniature camera-enabled mobile device a case shutter button mechanism for actuating the miniature camera module of the mobile camera system. A half-press or single tap triggers a precapture settings menu and a full-press or double tap triggers capture of an image.

A mobile device case for coupling around a mobile device that includes a miniature camera module has defined therein a lens attachment aperture shaped both to permit light from an object to be captured as a digital image to travel along the optical path of the miniature camera module to a built-in image sensor of the miniature camera module of the mobile device, and to facilitate stable coupling of an auxiliary lens in optical alignment with the miniature camera module. The case comprises electric circuit components positioned to balance an attached auxiliary lens approximately at a grip location.

A mobile device case is configured to facilitate coupling of an auxiliary lens assembly along an optical path of a miniature camera module of a mobile device. A case processor and electrical circuitry embedded within the case are configured to detect the presence of the auxiliary lens assembly that is coupled to the lens attachment interface. A lens recognition sensor is coupled to the case processor and electrical circuitry and is configured to identify the auxiliary lens with a specific lens type.

An image pickup apparatus that comprises a mechanism that causes a light emitting unit for illuminating to move from a storage position at which the light emitting unit is housed in the apparatus body to a light emission enabled position at which the light emitting unit protrudes outside of the apparatus body is provided. The image pickup apparatus comprises a holding member that holds the light emitting unit; a trigger coil that is provided at the light emitting unit; and a magnetic member that is held by the holding member. The magnetic member is arranged adjacent to the trigger coil so that a direction of a magnetic field of the magnetic member is not a direction opposite to a direction generated in the trigger coil by a first wave of a voltage input to the trigger coil.

An auxiliary optical assembly for a camera-enabled mobile device includes a removable lens assembly including a lens holder, a lens coupled to the lens holder, and a coupling interface. A lens attachment interface that is configured to stably couple to the mobile device, and that is configured in accordance with the coupling interface of the removable lens assembly to stably couple and align the removable lens along the optical path of the miniature camera module.

Disclosed is a system for improving chroma key compositing technique in photography and/or videography. The system comprises at least a first flashlight arranged to be directed towards an object to be photographed, a chrome backdrop in front of which the object is to be photographed, and at least a first reflecting surface arranged partly in front of the first flashlight in such a manner that part of the light from the first flashlight is directed to the object to be photographed and part of the light from the first flashlight is reflected towards the chrome backdrop. The first reflecting surface has essentially the same colour as the chrome backdrop.

Disclosed are a flash unit, a camera and a camera flash system, and relates to the technical field of underwater photographic equipment, including a flash lamp, capable of illuminating an photographed object; a video lamp, having the functions of color temperature adjustment and full color gamut coverage by light; a camera body, taking photos for the illuminated object; a waterproof case; a flash trigger, capable of generating an optical signal; and a repeater, capable of receiving the optical signal from the flash trigger, and then encoding and transmitting a new high-power optical signal. According to the present disclosure, under the cooperation of components such as the flash trigger and the repeater, the optical signal can be transmitted wirelessly over long distance underwater, thus achieving the effect of using the flash and video lamps far away from the camera. The present disclosure has a broad market application prospect.

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.

A camera module includes a lens module; a circuit board, disposed on the lens module, on which an image sensor is disposed; a light-emitting diode (LED) module disposed to be spaced apart from the circuit board; a post disposed between the circuit board and the LED module to support the LED module; and a first heat dissipation member disposed on the LED module.
