Abstract
The present invention provides an image focusing method that is applied to an image capture device having an optical image stabilization (OIS) function, including: driving the at least one optical lens to tilt by an angle in response to a first selected target and a second selected target, and enabling a first light beam group from the first selected target and a second light beam group from the second selected target to be focused on a same imaging surface after passing through the at least one optical lens. In addition, the present invention further provides an image capture device and an electronic device that apply the foregoing method.
Claims13
An image focusing method, applied to an image capture device having an optical image stabilization (OIS) function, wherein when the image capture device is provided with the OIS function, at least one optical lens of the image capture device is configured to be driven to tilt, and the image focusing method comprises:
- selecting a first target in a shot scene and a second target in the shot scene at a position different from that of the first target;
- calculating an angle by which the at least one optical lens needs to be tilted according to the first target and the second target;
- and
- driving the at least one optical lens to tilt by the angle to enable both a first light beam group from the first target and a second light beam group from the second selected target to be focused on a same imaging surface after passing through the at least one tilted optical lens.
An image capture device, comprising:
- a motion sensing element;
- at least one optical lens;
- an image sensing element, comprising an imaging surface;
- a processing unit connected to the image sensing unit and configured to calculate an angle by which the at least one optical lens needs to be tilted according to a first selected target in a shot scene and a second selected target in the shot scene at a position different from that of the first target;
- and
- a driving element, configured to drive, according to a sense result of the motion sensing element, the at least one optical lens to tilt, so as to provide an OIS function;
- wherein the driving element is connected to the processing unit and configured to drive the at least one optical lens to tilt by the angle to enable both a first light beam group from the first selected target and a second light beam group from the second selected target to be focused on the imaging surface after passing through the at least one tilted optical lens.
An electronic device, comprising:
- housing;
- and
- an image capture device, disposed in the housing, and comprising:
- a motion sensing element;
- at least one optical lens;
- an image sensing element, comprising an imaging surface;
- a processing unit connected to the image sensing unit and configured to calculate an angle by which the at least one optical lens needs to be tilted according to a first selected target in a shot scene and a second selected target in the shot scene at a position different from that of the first target;
- and
- a driving element, configured to drive, according to a sense result of the motion sensing element, the at least one optical lens to tilt, so as to provide an OIS function;
- wherein the driving element is connected to the processing unit and configured to drive the at least one optical lens to tilt by the angle to enable both a first light beam group from the first selected target and a second light beam group from the second selected target to be focused on the imaging surface after passing through the at least one tilted optical lens.
