Abstract

A method and a terminal for focusing includes: a determining step, determining a first camera focus of two camera focuses of two cameras corresponding to a first touch point of two touch points and a second camera focus of the two camera focuses of the two cameras corresponding to a second touch point of the two touch points, respectively, when a shooting preview interface corresponding to the two cameras is displayed and the two touch points are detected on the shooting preview interface; and a focus adjustment step, adjusting position of the first camera focus and the second camera focus, respectively, according to a sliding trace of the first touch point and a sliding trace of the second touch point on the shooting preview interface, in which the first camera focus and the second camera focus are on a same straight line.

First claim

What is claimed is:

1. A method for focusing applied in a terminal having two cameras, the two cameras being arranged in one side of the terminal, the method comprising:
determining, by a processor of the terminal, a first camera focus of two camera focuses of the two cameras corresponding to a first touch point of two touch points and a second camera focus of the two camera focuses of the two cameras corresponding to a second touch point of the two touch points, respectively, when a shooting preview interface corresponding to the two cameras is displayed and the two touch points are detected on the shooting preview interface; and
adjusting, by the processor of the terminal, a position of the first camera focus and a position of the second camera focus, respectively, according to a sliding trace of the first touch point, a sliding trace of the second touch point on the shooting preview interface, and a preset displacement and direction conversion rule, wherein the first camera focus and the second camera focus are on a same straight line,
wherein the preset displacement and direction conversion rule comprises:
a displacement ratio between a sliding displacement of the first touch point and a sliding displacement of the first camera focus and a displacement ratio between a sliding displacement of the second touch point and a sliding displacement of the second camera focus; and
a corresponding relationship between a sliding direction of the first touch point and a sliding direction of the first camera focus and a corresponding relationship between a sliding direction of the second touch point and a sliding direction of the second camera focus.

2. The method of claim 1 , wherein adjusting the position of the first camera focus and the position of the second camera focus, respectively comprises:
acquiring, by the processor of the terminal, the sliding trace of the first touch point and the sliding trace of the second touch point, respectively;
determining, by the processor of the terminal, the sliding direction and any of a sliding horizontal displacement and a sliding vertical displacement of the first touch point, according to the sliding trace of the first touch point;
determining, by the processor of the terminal, the sliding direction and a sliding displacement of the first camera focus in the preset displacement and direction conversion rule according to the sliding direction and any of the sliding horizontal displacement and the sliding vertical displacement of the first touch point;
determining, by the processor of the terminal, the sliding direction and any of a sliding horizontal displacement and a sliding vertical displacement of the second touch point, according to the sliding trace of the second touch point;
determining, by the processor of the terminal, the sliding direction and a sliding displacement of the second camera focus in the preset displacement and direction conversion rule according to the sliding direction and any of the sliding horizontal displacement and the sliding vertical displacement of the second touch point; and
adjusting, by the processor of the terminal, the position of the first camera focus according to the sliding direction and the sliding displacement of the first camera focus, and adjusting the position of the second camera focus according to the sliding direction and the sliding displacement of the second camera focus.

3. The method of claim 2 , further comprising:
moving, by the processor of the terminal, the first camera focus close to or apart from the second camera focus when the first touch point is moved close to or apart from the second touch point;
moving, by the processor of the terminal, the second camera focus close to or apart from the first camera focus when the second touch point is moved close to or apart from the first touch point; and
moving, by the processor of the terminal, the first camera focus and the second camera focus close to or apart from each other when the first touch point and the second point are moved close to or apart from each other.

4. The method of claim 1 , wherein a user can adjust at least one of the displacement ratio between the sliding displacement of the first touch point and the sliding displacement of the first camera focus, the displacement ratio between the sliding displacement of the second touch point and the sliding displacement of the second camera focus, the corresponding relationship between the sliding direction of the first touch point and the sliding direction of the first camera focus, or the corresponding relationship between the sliding direction of the second touch point and the sliding direction of the second camera focus.

5. The method of claim 1 , wherein determining the first camera focus of two camera focuses of the two cameras corresponding to the first touch point of two touch points and the second camera focus of the two camera focuses of the two cameras corresponding to the second touch point of the two touch points, respectively, comprises:
determining, by the processor of the terminal, whether the positions of the two camera focuses need to be adjusted according to a received focus selecting command when the shooting preview interface corresponding to the two cameras is displayed; and
determining, by the processor of the terminal, the first camera focus of the two camera focuses of the two cameras corresponding to the first touch point of the two touch points and the second camera focus of the two camera focuses of the two cameras corresponding to the second touch point of the two touch points when it is determined that the positions of the two camera focuses need to be adjusted and the two touch points are detected on the shooting preview interface.

6. The method of claim 1 , wherein adjusting the position of the first camera focus and the position of the second camera focus, respectively, comprises:
determining, by the processor of the terminal, the first camera focus of the two camera focuses of the two cameras corresponding to the first touch point of the two touch points and the second camera focus of the two camera focuses of the two cameras corresponding to the second touch point of the two touch points according to a relative position between the two touch points and a relative position between the two cameras.

7. A terminal comprising:
two cameras;
a memory storing computer-readable program codes; and
a processor configured to invoke the computer-readable program codes to:
determine a first camera focus of two camera focuses of the two cameras corresponding to a first touch point of two touch points and a second camera focus of the two camera focuses of the two cameras corresponding to a second touch point of the two touch points, respectively, when a shooting preview interface corresponding to the two cameras is displayed and the two touch points are detected on the shooting preview interface; and
adjust a position of the first camera focus and a position of the second camera focus, respectively, according to a sliding trace of the first touch point and a sliding trace of the second touch point on the shooting preview interface and a preset displacement and direction conversion rule, wherein the first camera focus and the second camera focus are on a same straight line,
wherein the preset displacement and direction conversion rule comprises a displacement ratio between a sliding displacement of the first touch point and a sliding displacement of the first camera focus and a displacement ratio between a sliding displacement of the second touch point and a sliding displacement of the second camera focus.

8. The terminal of claim 7 , wherein the computer-readable program codes to adjust a position of the first camera focus a
