As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
An embodiment of the present invention provides a method for focusing an image, as shown in fig. 1, the method includes:
101. in the manual focusing mode, a focusing adjustment instruction of a user is received.
According to different manual focusing modes, the focusing function can provide a focusing sliding shaft or a multi-point touch mode for a user, and correspondingly, the focusing adjustment instruction generally refers to sliding on a focusing line or multi-point touch of the user.
102. And responding to the focusing adjustment instruction, and adjusting the current focus position.
And the user can adjust the focal length of the camera based on the focusing instruction, and the corresponding focal position is determined by the sensor and fed back to the display interface.
103. And displaying the current focusing area according to the adjusted focus position.
Wherein the focusing area is generally shown by a selection frame of a specific shape, such as a circular frame.
Compared with the prior art that the focusing effect can be only checked on a small-area screen by naked eyes, the image focusing method provided by the embodiment of the invention can enable a user to clearly determine the focus position so as to finish more accurate focusing.
Further, in order to enable the user to clearly see the focusing condition, the method provided by the embodiment of the present invention further enlarges the image in the focusing area, so that the user can view the focusing condition more clearly, and the related flow is as shown in fig. 2, and after the step 103, the method includes:
104. and determining an image to be focused according to the current focusing area.
The image to be focused is an image in a certain range with a focusing position as a center.
105. And amplifying and displaying the image to be focused in a preview area.
The preview area is displayed in a first preset area of the display interface, generally the upper right corner, and the focusing position is generally in the center of the screen according to the focusing condition of actual shooting, and the upper right corner can be prevented from being overlapped with the focusing area to a certain extent, so that the watching of a user is not influenced.
Of course, if the focusing position of the object or landscape photographed by the user coincides with the first predetermined area, it is necessary to determine in advance whether there is coincidence between the current focusing area and the predetermined area when the preview area is displayed. When the current focusing area is overlapped with the preset area, the preview area is adjusted and displayed to a second preset area of the display interface. When the current focusing area is not overlapped with the preset area, the preview area is maintained to be displayed in the first preset area of the display interface.
For convenience of understanding, referring to the terminal display interface shown in fig. 3 as an example, in the expert mode (manual focusing mode), the user may perform focusing operation by sliding left and right on the focusing line, the focusing area is displayed in the center of the screen, and the preview area in the upper right corner displays an enlarged focusing image.
