Preferred embodiment of the invention

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

Method embodiment

Embodiment 1 In an embodiment of the present invention, a method for determining a shooting area is provided. As shown in FIG. 1, the method includes the following steps:

Step S101: After the camera or the camera function of the terminal is turned on, and the preview interface is displayed on the touch screen, the touch operation of the user on the preview interface is detected.

In operation, it is preferred to activate the camera or camera function of the terminal. After the startup, the preview interface is displayed on the touch screen of the terminal, and the user can perform the operation of defining the area on the touch screen. In this embodiment, a delineation area is provided. The method, that is, detecting a user's pressing operation and lifting operation on the touch screen, recording the coordinates of the pressing operation and the lifting operation on the touch screen, taking the upper left of the touch screen as the coordinate zero point, if and only if the lifting operation is horizontal The coordinate is greater than the abscissa of the pressing operation, and the ordinate of the lifting operation is greater than the ordinate of the pressing operation, that is, when the ordinate is pressed from the upper left to the lower right of the touch screen, the operation is effective. When the operation is valid, the coordinate line of the two points is diagonal, forming a rectangular area having a length of XI - X0 and a width of Y1 - Y0, where (XI , Y1 ) is the coordinate of the lifting operation , (X0, Y0 ) is the coordinate of the pressed operation. When the user needs to define the area, it is only necessary to perform a scribing operation on the touch screen to form a rectangular area, which is convenient for operation, and may of course form other shapes, for example, a circle. Other operations than the scribing operation can also be used to determine the delineation area.

After the designated area is formed, if the user wants to return to the initial interface of the preview, the user can slide from the lower right direction of the screen to the upper left side, that is, after the terminal detects the user pressing and lifting operations on the touch screen, the terminal is judged to lift up. Whether the horizontal coordinate of the operation is smaller than the abscissa of the pressing operation, and whether the vertical coordinate of the lifting operation is smaller than the vertical coordinate of the pressing operation, and if so, the preview interface on the touch screen is restored to the original interface. Of course, other methods for triggering the restoration of the original interface may be set, for example, long-pressing the designated area, and the terminal detects the long-press operation, and when the pressing time is greater than the preset time threshold, the current preview interface is restored to the original preview interface. Step S102: After detecting a touch operation of the user in the demarcated area on the preview interface, focus on the center of the delineation area.

When focusing on the center of the delineated area, first determine the coordinates of the center point of the delineated area. For example, the abscissa of the center of the rectangular area in step S101 is (XI - X0 ) /2, and the ordinate is (Yl - Y0 ) /2.

Step S103: After focusing on the center of the delineated area and obtaining a clear display content, the content is enlarged and displayed.

The enlarged area of the display content in this embodiment may be determined according to the size of the preview interface of the touch screen and the size of the delineated area. The formula for calculating the magnification is:

A=K ( S1/S2 ) ;

Where A is the magnification of the display content of the delineated area (Α > 1), K is the preset magnification factor, S1 is the area of the preview interface of the touch screen, and S2 is the area of the delineated area, and the value of K is preferably 0 < K 1 (K depends on the combination of different screens and cameras, can be fixed in the factory settings, of course, can also be opened to different users for advanced settings).

6, FIG. 7 and FIG. 8 are exemplified. FIG. 6 is an original preview interface, and B and a are on the interface. At this time, if the user wants to enlarge a in the upper left corner of the screen, the user can be delimited. Area (as shown in Figure 7), assuming that the delimited area is Sa=l cm ² , the area of the preview interface of the touch screen is S=5 cm ² , and the preset magnification factor is K=3/5, then the magnification is For Α = ( 3/5 ) 5 = 3 , that is, the display content of the area where a is located is magnified by 3 times, and FIG. 7 is a schematic enlarged view of the display content of the area where a is located.

Step S104: The enlarged display content is displayed centrally on the preview interface of the touch screen.

Embodiment 2

The embodiment provides a method for determining a shooting area. As shown in FIG. 2, the method includes the following steps: S201: Turn on the camera or camera function of the terminal, and display the preview interface on the touch screen, and detect the touch of the user on the preview interface. operating.

S202. After detecting a touch operation of the user in the demarcated area on the preview interface, the display content of the demarcated area is enlarged and stored. There are two main differences between this embodiment and the first embodiment:

1. After detecting the touch operation of the user in the demarcated area on the preview interface, the display content of the delineation area is directly enlarged, that is, the focusing step before enlarging the display content is omitted.

2. After zooming in the display content of the delineated area, the display content is not displayed on the preview interface of the touch screen, but the display content is directly stored, and the display content can be directly imaged after the display content is stored, and other subsequent operations can be performed.

Embodiment 3

The embodiment provides a method for scaling the shooting area, which is implemented on the basis of the first embodiment, that is, a method for scaling the enlarged area in the first embodiment, as shown in FIG. The following steps:

5301. Detect an operation of scaling the enlarged area on the touch screen.

Optionally, the user zooms the enlarged area as:

After detecting the pressing operation and the lifting operation on the touch screen, determining whether the abscissa of the lifting operation is smaller than the abscissa of the pressing operation, and whether the ordinate of the lifting operation is smaller than the ordinate of the pressing operation, If so, the user zooms the enlarged area.

Of course, other zoom operations can also be set, for example, long-pressing the area, the terminal detects a long press, and zooms in on the enlarged area when the pressed time is greater than the preset time threshold.

5302. After detecting an operation of scaling the enlarged area on the touch screen, scaling the enlarged area according to a scaling ratio.

In zooming, the zoomed area is scaled around the center of the enlarged area. In this embodiment, the zoom ratio may be determined according to the area of the preview interface of the touch screen and the area of the defined area, for example, A=K (S3/S1) ), where A is the zoom ratio, K is the zoom factor, S1 is the area of the preview interface of the touch screen, and S3 is the area of the delineated area (K is determined according to the combination of different screens and cameras, and can be fixed in the factory settings, of course It can also be opened to different users for advanced settings).

Of course, it is also possible to preset a fixed zoom ratio in the terminal. For example, after detecting the zoom operation of the user, the enlarged area is scaled by 1/2. Device embodiment
