Abstract
Aspects of the present disclosure relate to systems and methods for image focusing for devices including multiple cameras. An example method includes estimating a focus distance associated with an image captured by a first camera, determining, based at least in part on the estimated focus distance, to switch from the first camera to a second camera, switching from the first camera to the second camera, completing a focusing operation using the second camera and presenting an updated image captured by the second camera.
Claims25
An image capture device, comprising:
- a memory storing instructions;
- and
- a processor coupled to the memory and configured to:
- receive an image from a first camera;
- estimate a focus distance associated with the image;
- determine, based at least in part on the estimated focus distance, whether to switch from the first camera to a second camera;
- adjust a field of view (FOV) of the second camera to match a FOV of the first camera;
- switch from the first camera to the second camera;
- complete a focusing operation using the second camera;
- and
- capture an image, using the second camera, at the FOV.
A method, performed by an image capture device, the method comprising:
- estimating a focus distance associated with an image captured by a first camera;
- determining, based at least in part on the estimated focus distance, whether to switch from the first camera to a second camera;
- adjusting a field of view (FOV) of the second camera to match a FOV of the first camera;
- switching from the first camera to the second camera;
- completing a focusing operation using the second camera;
- capturing an image, using the second camera, at the FOV.
A non-transitory computer readable storage medium storing instructions that, when executed by one or more processors of an image capture device, cause the image capture device to:
- estimate a focus distance associated with an image captured by a first camera;
- determine, based at least in part on the estimated focus distance, whether to switch from the first camera to a second camera;
- adjust a field of view (FOV) of the second camera to match a FOV of the first camera;
- switch from the first camera to the second camera;
- complete a focusing operation using the second camera;
- capture an image, using the second camera, at the FOV.
