Touch photographing device and method based on pressure sensor, and mobile terminal

Abstract

The invention discloses a touch photographing device and method based on a pressure sensor, and a mobile terminal, and belongs to the technical field of communication. The device comprises a starting module, an acquisition module and a pressure judgment module, wherein the starting module is used for entering a photographing interface and starting the pressure sensor; the acquisition module is used for obtaining screen touching information and focusing a screen touching position area, wherein the screen touching information comprises a screen touching position and screen touching pressure; the pressure judgment module is used for judging whether the screen touching pressure is greater than a preset threshold value or not, and photographing the screen touching position if the screen touching pressure is greater than the preset threshold value; and otherwise, keeping a focusing state on the current screen touching position. The touch strength of a user under the photographing interface can be detected through the pressure sensor to distinguish the operations of soft touch and pressing so as to realize two-section shutter functions of soft touch focusing and pressing photographing, eliminate separation feeling generated during focusing and photographing, optimize a photographing flow and improve the photographing experience of the user.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a pressure sensor-based touch camera device, method and mobile terminal. Background technique [0002] Taking pictures is one of the most commonly used functions by users. In recent years, with the substantial improvement in the pixel and imaging capabilities of mobile phone camera elements, mobile phones have almost replaced card cameras in daily photo shooting scenarios. [0003] At present, the shutters of mobile phones can be roughly divided into two implementation methods: physical shutter and touch shutter. The physical shutter is to click a specific physical button (a physical shutter specially used for taking pictures or use volume keys instead) to take pictures; touch shutter includes but is not limited to the screen. virtual shutter button and tap the edge of the screen to take a photo. [0004] No matter how you take pictures, you can complete the proce...

AI Technical Summary

Problems solved by technology

[0005] 1. The user chooses to use the physical shutter to take pictures directly. The process is convenient and fast, but the camera can only focus on the center of the viewfinder area, so if the scene / object that the user needs to focus on is not in the center of the viewfinder area, then the final photo quality will be low for the user. Not ideal;

[0006] 2. The user chooses to click on a specific area of ​​the screen to focus on the scene / object he needs, and then use the touch shutter / physical shutter to take a photo. The quality of the photo obtained in this way should be ideal for the user, but the operation process is not smooth. sense of fragmentation;

[0007] 3. There is another disadvantage of using the physical shutter. The involuntary shaking of finger muscles when clicking the physical button to take pictures will also affect the image quality to a certain extent

[0008] In the prior art, there is also a method of using short-touch to focus on the viewfinder area in the camera and improving the method of long-touch to take pictures. This way of taking pictures solves the above-mentioned shortcomings to a certain extent, but it may be difficult to use the length of time to determine whether to take pictures. Make users dissatisfied while waiting
