Embodiment Construction

[0064] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0065] Terminal devices such as mobile phones and tablet computers are usually equipped with fingerprint recognition sensors to realize the fingerprint recognition function. Fingerprint recognition sensors include optical fingerprint recognition sensors, capacitive fingerprint recognition sensors, ultrasonic fingerprint recognition sensors and other types. Regardless of the type of fi...

Abstract

The invention relates to a pressure detection method and device, and belongs to the technical field of terminals. The method comprises the steps: sequentially collecting n fingerprint image frames through a fingerprint recognition sensor, wherein n is not less than two; recognizing sweat pores from each fingerprint image frame; respectively obtaining the features of the sweat pores in each fingerprint image frame; determining the change trend of the pressure applied to the fingerprint recognition sensor according to the change trend of the features of the sweat pores in the n fingerprint image frames. The method solves problems that terminal equipment is large in size, is not portable and is high in cost because only if terminal equipment is provided with a dedicated pressure induction module, can the related technologies achieve a pressure detection function. The method saves the pressure induction module group, facilitates the light and convenient design of the structure of the terminal equipment, and reduces the cost.

Description

technical field [0001] The present disclosure relates to the technical field of terminals, and in particular to a pressure detection method and device. Background technique [0002] Terminal devices such as mobile phones and tablet computers are electronic devices commonly used in people's daily life. [0003] In order to realize the pressure detection function on the terminal device, in related technologies, a special pressure sensing module is provided in the terminal device to detect the touch pressure acting on the pressure sensing module. In general, there are two different types of pressure sensing modules: resistive and capacitive. [0004] However, in the related art, it is necessary to install a special pressure sensing module in the terminal device to realize the pressure detection function, which leads to the problems that the terminal device is bulky, not portable, and high in cost. Contents of the invention [0005] In order to overcome the problems existing...
