Abstract

The invention relates to a power adapter, a control method, a control device and a mobile terminal, and the power adapter comprises an image lamp, a controller and an external change-over switch, Thecontroller is connected with the external change-over switch and used for determining the working mode of the power adapter according to the switching operation of the external change-over switch, andthe working mode comprises an image lamp mode. The controller is connected with the image lamp and receives flash lamp parameter information from the mobile terminal, the flash lamp parameter information is determined by the mobile terminal according to the data information, the data information comprises photometry data and shooting mode information selected by a user, and the photometry data comprises ambient light data in a preset range of the target shooting object. And the controller controls the image lamp to provide flash brightness for the target shooting object according to the flashlamp parameters. The purpose that the image lamp can flexibly flash according to the light environment information around the target shooting object and the shooting mode selected by the user is achieved, and a personalized shooting mode is provided.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a power adapter, a control method, a control device and a mobile terminal. Background technique [0002] With the rapid development of science and technology, the functions of mobile communication smart terminals are becoming more and more complete. Among them, the shooting function of mobile terminals has become an indispensable requirement in people's daily life. Whether it is beautiful scenery or delicious food, people will take pictures of them. Record the bits and pieces of life and extend the shelf life of memories. [0003] Because when taking a picture, an image light is needed to provide the required light brightness for the target object being photographed. In the prior art, the flash power of most video lights is a fixed value, and the positions of the video lights and the camera are fixed, and it is impossible to perform flexible flash according to the s...
