Patent number: 11520938Abstract: An approach is provided that detects when a digital camera has been set to a privacy mode that limits access to the digital camera. When in privacy mode, the digital camera receives a request to access the digital camera from an application. The approach determines whether the requesting application is allowed access to the digital camera while the digital camera is in the privacy mode. The requesting application is then allowed access to the digital camera in response to the determination being that the requesting application is allowed access to the digital camera. Likewise, the requesting application is inhibited access to the digital camera in response to the determination being that the requesting application is not allowed access to the digital camera.Type: GrantFiled: December 2, 2019Date of Patent: December 6, 2022Assignee: Lenovo (Singapore) Pte.
