Patent number: 10033910Abstract: The present approach relates to the synchronization of frame acquisition by a camera with an external event or trigger despite the camera lacking external control or synchronization capabilities. For example, inexpensive and/or consumer grade camera typically lack a control interface to explicitly synchronize with an external trigger event or external device. The present approach allows synchronization of such a camera lacking external synchronization capabilities with an external event or device.Type: GrantFiled: April 15, 2016Date of Patent: July 24, 2018Assignee: GENERAL ELECTRIC COMPANYInventors: Ralf Lenigk, Mark Marshall Meyers, Victor Petrovich Ostroverkhov, Timothy Toepfer, Keith Michael Looney
