Abstract

Embodiments of the present application provide an ultrasonic processing method, device, storage medium, and electronic equipment. The method includes: acquiring the current mode; if the current mode is the first mode, controlling the ultrasonic sensor to emit the first frequency of the first transmission frequency Ultrasonic signal; receive the first reflected signal of the first ultrasonic signal reflected by the obstacle, and obtain the target fingerprint information according to the first reflected signal; if the current mode is the second mode, control the ultrasonic sensor to emit the second transmission Frequency of the second ultrasonic signal, the second transmission frequency is lower than the first transmission frequency; receiving the second reflection signal of the second ultrasound signal reflected by the obstacle, and obtaining the target distance according to the second reflection signal information. The screen-to-body ratio of the display can be increased.

Description

technical field [0001] The present application relates to the field of electronic technology, in particular to an ultrasonic treatment method, device, storage medium and electronic equipment. Background technique [0002] With the development of electronic technology, electronic devices such as smart phones are used more and more frequently in users' lives. Usually, when an electronic device is in a call, the electronic device needs to detect the distance between the user's face and the electronic device, so as to control the display screen of the electronic device to turn on or off, thereby preventing the user's face from touching the electronic device. The display may cause misoperation. In scenarios where user identity needs to be verified, such as unlocking electronic devices, realizing shopping functions through electronic devices, and realizing payment functions through electronic devices, the electronic devices need to identify the user's fingerprint to determine whe...
