Embodiment 1

[0028] see figure 2 , shows the image rotation method provided by the embodiment of the present invention.

[0029] The method for rotating the picture is mainly applied in a mobile terminal, and specifically includes the following steps:

[0030] In step S101, on the picture display interface, receiving a press instruction from the user to press the screen;

[0031] In the embodiment of the present invention, when the user needs to rotate the picture, then on the display interface of the picture, the user presses the touch screen with a single finger, and at this time, the mobile terminal will receive a press command for the user to press the screen.

[0032] In step S102, a touch bar is generated according to the pressing instruction;

[0033] In the embodiment of the present invention, since the point where the finger touches the touch screen is not a standard circle, the generated touch bar is an approximately elliptical or rectangular touch bar.

[0034] In step S103,...

Embodiment 2

[0041] see image 3 , shows the image rotation method provided by the embodiment of the present invention.

[0042] The method for rotating the picture is mainly applied in a mobile terminal, and specifically includes the following steps:

[0043] In step S201, on the picture display interface, receiving a press instruction from the user to press the screen;

[0044] In the embodiment of the present invention, when the user needs to rotate the picture, then on the display interface of the picture, the user presses the touch screen with a single finger, and at this time, the mobile terminal will receive a press command for the user to press the screen.

[0045] In step S202, a touch bar is generated according to the pressing instruction;

[0046] In the embodiment of the present invention, since the point where the finger touches the touch screen is not a standard circle, the generated touch bar is an approximately elliptical or rectangular touch bar.

[0047] In step S203, ...

Embodiment 3

[0062] see Figure 4 , is a schematic diagram of the modules of the picture rotating device provided in Embodiment 3 of the present invention; for the convenience of description, only the parts related to the embodiment of the present invention are shown. The image rotating device includes: an instruction receiving module 101 , a generating module 102 , a recording module 103 , a calculating module 104 , and a control module 105 . The image rotating device may be a software unit, a hardware unit or a combination of software and hardware built in the mobile terminal.

[0063] The command receiving module 101 is configured to receive a press command for the user to press the screen on the picture display interface;

[0064] A generating module 102, configured to generate a touch bar according to the pressing instruction;

[0065] A recording module 103, configured to record the movement track of the touch bar;

[0066] A calculation module 104, configured to calculate the rot...

Abstract

The invention provides a picture rotating method and device. The picture rotating method comprises the following steps that on a picture display interface, a pressing instruction generated when a user presses a screen is received; a touch bar is generated according to the pressing instruction; the moving track of the touch bar is recorded; the rotating direction and the rotating angle of the touch bar are calculated according to the moving track; the picture is controlled to rotate in the corresponding direction and by a corresponding angle according to the rotating direction and the rotating angle of the touch bar. According to the picture rotating method and device, rotation operation of the picture can be achieved through a single finger, so that compared with double-finger operation in the prior art, operation is simpler and more convenient, operation of the user is convenient, and thus the friendly experience of the user is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of picture processing, in particular to a picture rotation method and device. Background technique [0002] In the prior art, the rotation gesture of the picture requires two fingers to press and hold the touch screen at the same time, such as figure 1 As shown, and rotate clockwise or counterclockwise to realize the rotation function of the picture. However, the existing technology requires two fingers to operate, and the user experience is not good. [0003] Therefore, it is necessary to propose a new technical solution to solve the above technical problems. Contents of the invention [0004] In view of this, the object of the present invention is to provide a method and device for rotating a picture, which aims to solve the problem that the rotation gesture of a picture in the prior art requires two fingers to press and hold the touch screen at the same time, and rotate clockwise or counterclo...
