Problems solved by technology

[0004] However, in the prior art, it is necessary to support the terminal device at the same time and slide with two fingers when zooming, so on the one hand, there is a problem of inconvenient operation
On the other hand, due to the limitation of the sensitivity of the touch screen during the sliding process, the sensitivity will decrease in some cases (for example, the terminal device is suspended in the air or placed on the table, etc.), resulting in the failure of the scribing action, resulting in scaling operation failed

Embodiment 1

[0044] Please refer to figure 1 , figure 1 It is a flow chart of Embodiment 1 of the image scaling method provided by the present invention. The execution subject of this embodiment is a user equipment, and the user equipment may be implemented by any software and / or hardware. Specifically, the user equipment may be a mobile phone, a video camera, a camera, a computer, etc., and other user equipment capable of image processing may also serve as an execution subject of this embodiment. As for the specific implementation manner of the user equipment in this embodiment, this embodiment will not repeat it here. The methods include:

[0045] S101. Receive a touch operation on an image to be zoomed, and acquire a touch area corresponding to the touch operation;

[0046] S102. Perform zoom processing on the image to be zoomed according to the touch area.

[0047] Specifically, the picture may be a picture downloaded by the user from the Internet, or may be obtained by the user t...

Embodiment 2

[0071] This embodiment provides a picture scaling method, such as figure 2 shown, which includes:

[0072] S201. Receive a touch operation performed on an image to be zoomed, and detect a touch time of the touch operation;

[0073] S202. Acquire a touch area corresponding to the touch operation when the touch time is greater than a preset time threshold;

[0074] S203. Perform zoom processing on the image to be zoomed according to the touch area.

[0075] Specifically, the time threshold is preset, for example, 30 milliseconds. The touch time refers to the duration of the touch operation. Comparing the touch time with a preset time threshold can avoid the problem of misoperation caused by mistaken touch, and further improve the efficiency of the zooming process. accuracy. It is worth noting that other steps in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

Embodiment 3

[0077] This embodiment provides a picture scaling method, such as image 3 shown, which includes:

[0078] S301. Receive a touch operation performed on an image to be zoomed, and acquire a touch area corresponding to the touch operation;

[0079] S302. Compare the touch area with an area threshold;

[0080] S303. When the touch area is smaller than or equal to an area threshold, perform scaling processing on the image to be zoomed according to the touch area;

[0081] S304. When the touched area is larger than the area threshold, discard the touched area.

[0082] Specifically, the area threshold is used to calculate the scaling factor of the zooming process, that is, the scaling factor (maximum scaling factor) corresponding to the area threshold is preset, so that according to the relationship between the touch area and the area threshold Determine the scaling factor corresponding to the touch area. In practical applications, if the zoom factor threshold corresponding to ...

Abstract

The invention discloses a picture zooming method, a storage medium and a terminal device. The method includes the steps of receiving touching operation on a picture to be zoomed, and obtaining a touching area corresponding to the touching operation; according to the touching area, conducting scaling treatment on the picture to be zoomed. By obtaining the touching area of the touching operation, zooming is conducted according to the touching area, and therefore a user can use one finger to press the picture to conduct zooming operation. On the one hand, the problem of invalid zooming function caused by disconnection during the process of zooming the picture is solved; on the other hand, users' operation during zooming and processing procedures of the picture is simplified, and the operation and control efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of intelligent terminals, in particular to a picture zooming method, a storage medium and a terminal device. Background technique [0002] The image scaling technology includes two technologies of image enlargement and image reduction. In daily applications, when a user browses photos on a user device, the image is zoomed. [0003] In the prior art, in the process of using the terminal device to browse pictures, the user needs to perform a two-finger pinch operation at the position that needs to be zoomed in, and the terminal device will take the center point of the line connecting the two-finger pinch point on the screen as the center to perform image zooming. zoom. [0004] However, in the prior art, it is necessary to simultaneously support the terminal device and slide with two fingers when zooming, which has the problem of inconvenient operation on the one hand. On the other hand, due to the ...
