Problems solved by technology

[0005] However, in the prior art, the scheme of controlling the flash according to the ambient light detected by the light sensor has the problem of false triggering, which is explained as follows
[0006] In general, users need to hold a device for photography, and when the user's hand blocks the light sensor, the amount of light detected by the light sensor will be reduced, causing the ambient light detection value to be lower than the actual value, resulting in an error in the control algorithm The judgment needs to turn on the flash

Embodiment Construction

[0059] In the method, device and electronic device for controlling a flashlight in the embodiments of the present invention, the flashing intensity of the flashlight is controlled according to the pupil area of ​​the user in the current shooting environment. Since the pupil area can truly reflect the ambient light intensity, and the possibility that the pupil is blocked and cannot truly reflect the ambient light intensity is far less than the possibility that the light sensor is blocked, the embodiment of the present invention greatly reduces the detection impact compared to the prior art. The possibility of interference, which in turn can improve the control accuracy of the flash control.

[0060] A method for controlling a flashlight in an image acquisition device according to an embodiment of the present invention, such as figure 1 shown, including:

[0061]Step 101, acquiring the actual size of the user's pupil in the current shooting environment;

[0062] Step 102, cont...

Abstract

The invention discloses a method, a device and electronic equipment for controlling a flash lamp, aiming to increase the control accuracy of the flash lamp. The method comprises the following steps: obtaining the actual size of pupils of a user in a current shooting environment; and controlling the flash intensity of the flash lamp according to the actual size of the pupils. According to the embodiment of the method, the device and the electronic equipment, the possibility of interference in the process of ambient light detection is greatly reduced, thereby increasing the control accuracy of the flash lamp.

Description

technical field [0001] The invention relates to the technical field of image acquisition and control, in particular to a method, device and electronic equipment for controlling a flashlight. Background technique [0002] With the development of science and technology, digital image acquisition equipment or other portable electronic equipment with shooting function has become the standard equipment for every user. [0003] The use of flash plays a decisive role in photography. For example, flash can be used to supplement light when the light is insufficient. [0004] For the control of the flashlight, most of the prior art adopts a scheme of using a light sensor to collect ambient brightness, and then controlling whether the flashlight is turned on or not according to the ambient brightness. [0005] However, there is a problem of false triggering in the solution of controlling the flashlight according to the ambient light detected by the light sensor in the prior art, which...
