摘要： A camera captures visual and infrared images through a single lens assembly by inserting a beam splitter along the path of light proceeding through the lens assembly to pass a first light spectrum to a first image sensor along the lens axis and reflect a second light spectrum to a second image sensor along a reflection axis. For example, a hot mirror reflects infrared light along the reflection axis and passes through visible light along the lens axis, and a cold mirror reflects visible light along the reflection axis and passes infrared light through along the lens axis. Processing of an infrared image to define boundaries of a visible image provides a high quality composite image.

摘要： An information handling system peripheral camera analyzes captured visual images to detect a face and analyzes the face to determine an upright orientation. Based upon the face upright orientation, the camera defines a visual image orientation to communicate the visual image from the peripheral camera to an information handling system so that the face is communicated in an upright orientation for use in a video conference, such as with an indication of a landscape or portrait image orientation. In one embodiment, an information handling system can perform the face upright orientation analysis and command a camera orientation to the camera so that visual images of the camera are communicated in alignment with the face upright orientation.

摘要： An information handling system display peripheral includes a peripheral camera in a cavity that extends out to capture visual images for communication through a cable to the display peripheral and from the display peripheral to the information handling system. The camera peripheral separates from the display peripheral with removal from the cavity and extension of the cable from a spool so that the camera peripheral can capture visual images from a variety of positions around the display peripheral, such as by resting on a support surface with feet that extend out from the camera peripheral or by coupling to a surface with an adhesive tape on a back side of the camera peripheral.

摘要： An information handling system camera captures visual images of light directed by a lens towards an image sensor. The camera has an active illumination privacy shutter that disables the image sensor from capturing visual images by introducing illumination between the lens and image sensor, such as with a red light emitting diode that is seen as a red dot at the lens when viewed from in front of the camera. In one embodiment, the illumination is directed towards a light diffuser, such as a sheet of acrylic, that extends between the lens and image sensor when the camera is commanded to a privacy mode.

摘要： An information handling system camera leverages telephoto optics by a moveable mirror interfaced with a first camera having a lens with a narrow field of view to capture portions of a wide field of view of a second camera lens so that the camera has improved visual images captured of participants at various distances from the camera. In one embodiment, visual images captured along first and second axes are interleaved to present a videoconference presentation streamed with visual images of both axes, such as a split screen of different videoconference participants.

摘要： A monitor stand provides a self-aligning and self-orientating swivel lock mechanism for desktop monitors so the monitor stand can be easily locked at the center position to provide better user experience and easier manufacturing. A base of a monitor stand has a die cast plate and a swivel plate attached thereto to allow the monitor stand to rotate from the center position. A lock plunger of a swivel lock mechanism travels along a circular guided cam profile on the swivel plate when the swivel lock mechanism is engaged and the monitor stand is rotated. When the swivel lock mechanism rotates to the center position, a recessed portion of the circular guided cam profile receives the lock plunger of the swivel lock mechanism to thereby lock the swivel plate at the center position. The user engages/disengages the swivel lock mechanism by pushing an engagement button that extends from the base.

摘要： Plural cameras cooperate to define an overlap of fields of view that consolidate to provide an extended field of view communicated to an information handling system. The plural cameras stitch the non-overlapping portions into a consolidated visual image by reference to a landmark captured by both cameras in the overlapping portion, such as a reference marker placed in the extended field of view. The plural cameras coordinate through a wireless interface or with a daisy chain of communication cables to share the overlap boundary, resolution compatibility and an architecture for communicating the consolidated field of view with the information handling system.

摘要： An accessibility device interfaces with a display through a cable to accept display onscreen menu items for presentation as speech from the accessibility device. For instance, a scalar of the display detects an interface with an external accessibility device and an end user interaction with an onscreen display and, in response, commands onscreen items as audible sounds presented at a speaker of the accessibility device. When the display has integrated display speakers, the scalar adjusts any audible sounds presented by the display speakers to help ensure that the onscreen display menu items are presented with sufficient volume to be heard, such as by lower the volume or turning off the audible sounds presented from the display speakers.
