Appl. No.:

17/872529

International Classification:

H04N 5/232
H04N 5/235

Abstract:

A camera mode to use for capturing an image or video is selected by estimating high dynamic range (HDR), motion, and light intensity with respect to a scene of the image or video to capture. An image capture device includes a HDR estimation unit to detect whether HDR is present in a scene of an image to capture, a motion estimation unit to determine whether motion is detected within the scene, and a light intensity estimation unit to determine whether a scene luminance for the scene meets a threshold. A mode selection unit selects a camera mode to use for capturing the image based on output of the HDR estimation unit, the motion estimation unit, and the light intensity estimation unit. An image sensor captures the image according to the selected camera mode.

International Classification:

H04L 29/06

Abstract:

Various techniques and mechanisms for sharing remote resources among a trusted group are disclosed. A credential management agent utilizes a resource credential for a first user to access a secure resource corresponding to the first user for a second user by at least validating a second user and validating a consent of the first user to allow the second user to access the secure resource using the resource credential for the first user. The secure resource resides on a remote server system accessible via one or more application program interfaces (APIs). A platform management agent provides an interface for shared resource-agnostic credential sharing. The platform management agent validates credentials for the second user as belonging to a trusted group and forwards a request for access to the secure resource for the second user to the credential management agent. In response to receiving the resource credential for the first user to access the secure resource, the platform management agent accesses the secure resource on behalf of the second user to allow the second user to utilize the secure resource.
