example 1
[0042] By querying the mapping relationship table between current and distance, the current value corresponding to the current distance value is determined.
[0043] For example, the flashlight control device can pre-store the mapping relationship table between current and distance. After obtaining the current distance value between the target object and the terminal device, the mapping relationship table can be queried to determine the current value corresponding to the current distance value. .
[0044] Wherein, in the mapping relationship table between current and distance, a current value may correspond to a distance value, or a current value may also correspond to a distance range, which is not limited in this embodiment.
example 2
[0046] A current value corresponding to the current distance value is determined according to I=k×D, wherein I is a current value, k is a proportional constant, and D is a current distance value.
[0047] Among them, k is a positive number greater than 1 and less than 1.5, such as k can take 1.1, 1.2, 1.25, 1.3, etc.; or k can also choose different values at different distance values, for example, when D is less than 1 meter (m), k can take 1.25, and when k is greater than 1m, k can take 1.2.
[0048] Specifically, after the current distance value between the target object and the terminal device is obtained, the above relational expression can be used to determine the corresponding current value.
[0049] For example, when k is 1.2 and D is 1.5m, the determined current value is 1.3 ampere (A).
[0050] Step 103, adjusting the working current of the flashlight according to the current value.
[0051] Specifically, through the above method, after the power supply current co...

Abstract
The invention provides a flashlight control method, device and terminal equipment. The method comprises the following steps: acquiring a current distance value between a target object and the terminal equipment; determining a current value corresponding to the current distance value according to a relationship between a preset current and a distance; and adjusting a working current of a flashlight according to the current value. Through the flashlight control method, device and the terminal equipment provided by the invention, the working current of the flashlight can be adjusted dynamically along with the distance between the target object and the terminal equipment, the exposure effect of the target object under different distances can be guaranteed to be consistent, the performance of a camera in the terminal equipment can be improved, and the user experience can be improved.
Description
technical field [0001] The present application relates to the technical field of communications, and in particular to a flash control method, device and terminal equipment. Background technique [0002] Currently, a camera function is integrated in terminal equipment, so that people can use the terminal to realize a camera function. And the terminal device is also equipped with a flashlight, so that photos can still be discharged in a dark environment, but the current of the current flashlight is fixed, which makes the effect of taking pictures poor. Contents of the invention [0003] This application aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, the first purpose of this application is to propose a flash control method, which realizes the dynamic adjustment of the operating current of the flash according to the distance between the target and the terminal device, and ensures that the exposure effect...
