Abstract
Some aspects of the disclosure provide a method for camera operation control in an electronic device. The method includes obtaining, based on a plurality of frames associated with a target time slice, a first target parameter to be met by a camera of a virtual camera system in the target time slice. Then, the method includes determining a target operation speed of the camera in the target time slice at least partially based on the first target parameter and a time-speed change magnification curve, and controlling the camera to operate based on the target operation speed. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are also contemplated.
Claims20
A method for camera operation control in an electronic device, comprising:
- obtaining, by processing circuitry and based on a plurality of frames associated with a target time slice, a first target parameter including at least one of a position to be focused by a virtual camera and a zoom of the virtual camera in the target time slice;
- determining, by the processing circuitry, a target operation speed of changing the at least one of the position and the zoom of the virtual camera in the target time slice at least partially based on the first target parameter and a time-speed change magnification curve indicating a relationship between time within the target time slice and a speed change associated with changing the at least one of the position and the zoom of the virtual camera;
- and
- generating a view of a virtual scene by controlling the virtual camera to operate based on the determined target operation speed.
An apparatus, comprising
- processing circuitry configured to:
- obtain, based on a plurality of frames associated with a target time slice, a first target parameter including at least one of a position to be focused by a virtual camera and a zoom of the virtual camera in the target time slice;
- determine a target operation speed of changing the at least one of the position and the zoom of the virtual camera in the target time slice at least partially based on the first target parameter and a time-speed change magnification curve indicating a relationship between time within the target time slice and a speed change associated with changing the at least one of the position and the zoom of the virtual camera;
- and
- generate a view of a virtual scene by controlling the virtual camera to operate based on the determined target operation speed.
A non-transitory computer-readable medium storing instructions which when executed by processing circuitry causing the processing circuitry to perform:
- obtaining, based on a plurality of frames associated with a target time slice, a first target parameter including at least one of a position to be focused by a virtual camera and a zoom of the virtual camera in the target time slice;
- determining a target operation speed of changing the at least one of the position and the zoom of the virtual camera in the target time slice at least partially based on the first target parameter and a time-speed change magnification curve indicating a relationship between time within the target time slice and a speed change associated with changing the at least one of the position and the zoom of the virtual camera;
- and
- generating a view of a virtual scene by controlling the virtual camera to operate based on the determined target operation speed.
