More Information
Summary:The present invention is a method and a processing device that allows smoothing of all camera parameters that are changeable while the camera is running through a tasklist component that schedules transitions synchronized with the output video frame rate. A device-native thread runs the scheduler which picks smoothing tasks off a list to meet real-time requirements. Different strategies for smoothing based on Bézier curves, splines and linear interpolation are scheduled on the runtime. The camera, which is automatically able to detect people and frame them based on where they are, uses this module to smoothly change the frame when people move in the camera field of view, among other functions.
