Abstract: An audio capture device for a submersible camera including a supporting structure to prevent a waterproof membrane from deflecting beyond a point that will cause damage to the membrane. A microphone assembly includes a microphone for detecting ambient sound and generating an electrical signal representing the ambient sound. The microphone assembly is covered by a waterproof membrane to prevent water from reaching the microphone assembly. One or more supporting rings near the waterproof membrane prevents the waterproof membrane from deflecting more than a threshold deflection.

Abstract: A computer-implemented method for lighting subjects for artificial reality scenes may include (i) identifying (a) a physical camera configured to capture a physical subject for insertion into an artificial reality scene, (b) a physical light source that is positioned such that the physical light source lights the physical subject recorded by the physical camera, and (c) lighting conditions in the artificial reality scene, (ii) determining at least one lighting parameter to light the physical subject such that lighting conditions of the physical subject blend visually with the lighting conditions in the artificial reality scene, and (iii) configuring the physical light source to light the physical subject according to the at least one lighting parameter. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: Disclosed herein is a lighting apparatus capable of uniformly maintaining power consumed by light emitting units even in the case in which various voltages are applied, and increasing power efficiency while minimizing a heating problem by adjusting a reference voltage applied to a connection structure of the light emitting units and a distribution switch according to magnitude of the applied voltage.

Abstract: Approaches for managing a library of digital images and information about any editing operations performed on those digital images are provided. A managed library of digital images and a referenced library of digital images may be maintained. Digital images may be moved from the managed library of digital images to the referenced library of digital images, and vice-versa. A preview digital image data may also be generated from master digital image data. Rather than performing image operations directly on the master digital image data, change data that identifies one or more operations to perform to a digital picture represented by either the preview digital image data or the master digital image data may be stored, thereby allowing operations to be performed on the preview digital image data when the master digital image data is not accessible. Digital image may be automatically renamed based on rules for doing so.

Abstract: A sound pickup device is designed for an imaging apparatus including an objective lens and a camera casing. The sound pickup device includes first and second microphone holders fixed to the camera casing and each having an inner wall surface neighboring and facing a surface of the camera casing. First and second microphone units are held by the first and second microphone holders, respectively. The first and second microphone holders are located at left and right sides of the camera casing respectively while being separated from each other in a direction perpendicular to an optical axis of the objective lens. The aforesaid surface of the camera casing forms a sound reflecting surface which reflects incoming sound. Each of the first and second microphone units has a sound pickup surface facing the sound reflecting surface to pick up the sound reflected by the sound reflecting surface.

Abstract: An optical apparatus includes a control unit configured to perform an operation for moving a focusing lens at a first speed to detect a first position corresponding to an in-focus state and then moving the focusing lens at a second speed lower than the first speed in forward and backward directions across the first position to detect a second position corresponding to an in-focus state, and an output unit configured to output information indicating an in-focus state of the focusing lens recognizable by a user. The output unit outputs the information in response to the control unit detecting the first position.

Abstract: Remotely operable electronic apparatus are applied to distance measurement and picture/sound recording wherein, for example, a remote unit may be equipped with a microphone and an active range finder coupled to an auto-focussing capability. In one embodiment a camera is adapted to transmit a signal to the remote unit which returns a signal enabling the camera to accurately calculate distance and adjust focus in accordance with time-of-flight. The transponder preferably forms part of a wireless microphone, with the signal transmitted by the camera being preferably acoustical in nature. The acoustical signal transmitted by the camera is preferably modulated onto a return RF signal, enabling at least a portion of the audio circuitry associated with voice modulation to be used for the purpose of modulating the ranging signal, thereby realizing a very efficient and economical approach to remote sound detection and active ranging finding.
