摘要： Example virtual-reality head-mounted devices having reduced numbers of cameras, and methods of operating the same are disclosed herein. A disclosed example method includes providing a virtual-reality (VR) head-mounted display (V-HMD) having an imaging sensor, the imaging sensor including color-sensing pixels, and infrared (IR) sensing pixels amongst the color-sensing pixels; capturing, using the imaging sensor, an image having a color portion and an IR portion; forming an IR image from at least some of the IR portion from the image; performing a first tracking based on the IR image; forming a color image by replacing the at least some of the removed IR portion with color data determined from the color portion of the image and the location of the removed IR-sensing pixels in the image; and performing a second tracking based on the color image.

摘要： An immersive video teleconferencing system may include a transparent display and at least one image sensor operably coupled to the transparent display. The at least one image sensor may be multiple cameras included on a rear side of the transparent display, or a depth camera operably coupled to the transparent display. Depth data may be extracted from the images collected by the at least one image sensor, and an image of a predetermined subject may be segmented from a background of the collected images based on the depth data. The image of the segmented predetermined subject may also be scaled based on the depth data. The image of the scaled segmented predetermined subject may be transmitted to a remote transparent display at a remote location, and displayed on the remote transparent display such that a background surrounding the displayed image of the remote location is visible through the transparent display, so that the predetermined subject appears to be physically located at the remote location.

摘要： An integrated stacked and/or abutted sensor, memory and processing hardware camera solution is described. The sensor is to receive light from an image and generate electronic pixels from the light. The processing hardware is to process the electronic pixels to: a) recognize a scene from the image in a lower quality image mode; b) trigger actions by the camera solution in response to the recognition of the scene, the actions including: i) transitioning the camera solution from the lower quality image mode to a higher quality image mode to capture a higher quality version of the image; and, ii) forwarding from the camera solution important imagery and not forwarding from the camera solution unimportant imagery.

摘要： A camera apparatus is described that includes a frame housing and a camera module affixed to the frame housing. The camera module may include a lens and an image sensor. The camera apparatus may include a reflective element and a motor. The reflective element may be disposed within the frame housing, the reflective element being movable relative to the lens to select a direction from which the lens collects light. The motor may be adapted to move the reflective element in response to detecting a magnetic field change generated by at least one magnet disposed within the frame housing.
