Abstract
A multi-camera zooming method includes: during zooming from an i-th magnification range to an adjacent j-th magnification range, a j-th camera corresponding to the j-th magnification range is selected from n cameras, 1≤i≤n and 1≤j≤n; when the j-th camera is in a non-operating state, a transition camera and a target camera are determined; the transition camera is set as a camera configured to acquire a preview image; the target camera is unloaded from an operating state to the non-operating state and the j-th camera is loaded from the non-operating state to the operating state; and the camera configured to acquire the preview image is switched from the transition camera to the j-th camera.
Claims20
A multi-camera zooming method, applied to a mobile terminal, the mobile terminal including n cameras and an image processor coupled with the n cameras, and the image processor simultaneously supporting m cameras in an operating state, where n and m are integers and n>m≥2, the method comprising:
- during zooming from an i-th magnification range to an adjacent j-th magnification range, selecting a j-th camera corresponding to the j-th magnification range from the n cameras, where 1≤i≤n and 1≤j≤n;
- when the j-th camera is in a non-operating state, determining a transition camera and target camera from the m cameras in the operating state;
- setting the transition camera as a camera configured to acquire a preview image;
- unloading the target camera from the operating state to the non-operating state and loading the j-th camera from the non-operating state to the operating state;
- and
- switching the camera configured to acquire the preview image from the transition camera to the j-th camera.
A mobile terminal, the mobile terminal including n cameras and an image processor connected with the n cameras, and the image processor simultaneously supporting m cameras in an operating state, where n and m are integers and n>m≥2, the image processor is configured to:
- during zooming from an i-th magnification range to an adjacent j-th magnification range, select a j-th camera corresponding to the j-th magnification range from the n cameras, where 1≤i≤n and 1≤j≤n;
- when the j-th camera is in a non-operating state, determine a transition camera and target camera from the m cameras in the operating state;
- set the transition camera as a camera configured to acquire a preview image;
- and
- unload the target camera from the operating state to the non-operating state and load the j-th camera from the non-operating state to the operating state,
- switch the camera configured to acquire the preview image from the transition camera to the j-th camera.
A non-transitory computer-readable storage medium having stored thereon at least one instruction, which is loaded and executed by a processor to implement the multi-camera zooming method, the multi-camera zooming method applied to a mobile terminal, the mobile terminal including n cameras and an image processor connected with the n cameras, and the image processor simultaneously supporting m cameras in an operating state, where n and m are integers and n>m≥2, the method including:
- during zooming from an i-th magnification range to an adjacent j-th magnification range, selecting a j-th camera corresponding to the j-th magnification range from the n cameras, where 1≤i≤n and 1≤j≤n;
- when the j-th camera is in a non-operating state, determining a transition camera and target camera from the m cameras in the operating state;
- setting the transition camera as a camera configured to acquire a preview image;
- unloading the target camera from the operating state to the non-operating state and loading the j-th camera from the non-operating state to the operating state;
- and
- switching the camera configured to acquire the preview image from the transition camera to the j-th camera.
