Problems solved by technology

[0004] However, since the surface of the finger pulp (the inner side of the first joint, opposite to the nail) is a curved surface, when the user clicks the virtual camera button with a finger, the actual pressing area of ​​the finger will be smaller than the surface area of ​​the finger pulp, which is prone to user subjective problems. It is believed that the sensing area corresponding to the virtual camera button has been pressed, but it has not been pressed. As a result, the virtual camera button cannot respond to the user's click operation, and the user experience is poor.

Embodiment 1

[0024] figure 1 A schematic flowchart of a method for triggering a virtual camera button provided in Embodiment 1 of the present invention, the method can be executed by a device for triggering a virtual camera button, wherein the device can be implemented by software and / or hardware, and can generally be integrated in a mobile terminal . Such as figure 1 As shown, the method includes:

[0025] Step 101, when it is detected that the screen is pressed, determine the pressed area.

[0026] Exemplarily, the mobile terminal in this embodiment may specifically be a terminal device such as a mobile phone, a tablet computer, and a digital camera equipped with a touch screen.

[0027] Common camera buttons in mobile terminals include physical camera buttons and virtual camera buttons. The virtual camera button can be a button pattern displayed on the screen of the mobile terminal, and is generally located in the middle and lower part of the screen. When the user uses the mobile t...

Embodiment 2

[0037] image 3It is a schematic flowchart of a method for triggering a virtual camera button provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiments. Determining the target area" is optimized as: calculating the area of ​​the pressing area; determining the target area according to the area of ​​the pressing area and the preset area gain value; determining the target area according to the center of the pressing area and the target area.

[0038] Correspondingly, the method of this embodiment includes the following steps:

[0039] Step 301, when it is detected that the screen is pressed, determine the pressed area.

[0040] Step 302, calculating the area of ​​the pressing area.

[0041] Step 303. Determine the target area according to the area of ​​the pressing area and the preset area gain value.

[0042] Exemplarily, the sum of the area of ​​the pressing area and the preset area gain value is used as t...

Embodiment 3

[0049] Figure 4 It is a schematic flowchart of a method for triggering a virtual camera button provided by Embodiment 3 of the present invention. This embodiment is optimized on the basis of the above embodiments. In this embodiment, the preset area gain value is the difference between the area of ​​the fingerprint image and The product of the preset gain factors.

[0050] Further, before detecting that the screen is pressed, the method may further include: acquiring a fingerprint image and calculating the area of ​​the fingerprint image to obtain the area of ​​the fingerprint image.

[0051] Correspondingly, the method of this embodiment includes the following steps:

Abstract

The embodiment of the invention discloses a method, device and mobile terminal for triggering a virtual camera button. The method includes: determining the pressing area when the screen is pressed; determining the target area according to the pressing area and a preset area adjustment strategy, wherein the target area includes the pressing area, and the area of ​​the target area is larger than the area of ​​the pressing area; when the target area When the sensing area corresponding to the virtual camera button overlaps, the virtual camera button is triggered. In the embodiment of the present invention, by adopting the above-mentioned technical solution, when the user wants to take a photo by clicking the virtual photo button, the probability of the virtual photo button being triggered can be increased, so that the triggering of the virtual photo button is more in line with the user's psychological expectation, and the existing The trigger scheme of the unique virtual camera button improves the user experience.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mobile terminals, in particular to a method and device for triggering a virtual camera button, and a mobile terminal. Background technique [0002] At present, the camera function has become a standard configuration of mobile terminals, and mobile terminal users can easily record the scenery and wonderful moments around them in their daily life. [0003] Common camera buttons in mobile terminals include physical camera buttons and virtual camera buttons. The virtual camera button is a button pattern displayed on the screen of the mobile terminal, and is generally located at the middle and lower part of the screen. When the user uses the mobile terminal to take pictures, he can use his finger to click the virtual camera button on the screen. When the mobile terminal recognizes that the pressing area of ​​the user's finger overlaps with the sensing area corresponding to the virtua...
