Problems solved by technology

However, no matter it is the flashlight module on the original electronic device or the external flashlight device, the emission direction of the light is the same as the shooting direction of the lens and is fixed, so the photos taken still have the problem of uneven brightness, such as Some of the photos taken may be dark or bright
[0004] In view of this, a flash device that can solve the problem of insufficient brightness or uneven brightness in taking photos is a topic worthy of research

Abstract

The invention discloses a flashlight device, which comprises a base, a plurality of rotating mechanisms, a plurality of lens modules, at least one light source and a control circuit. A plurality of rotating mechanisms are arranged on the base. A plurality of lens modules are respectively installed on a plurality of rotating mechanisms. The at least one light source is used for emitting light. The control circuit is used to receive an external command signal to generate a first control signal and a second control signal. Wherein, the control circuit sends the first control signal to at least one rotating mechanism, thereby controlling the at least one rotating mechanism to drive the corresponding lens module to rotate, and the control circuit sends the second control signal to the light source, thereby controlling the A brightness of light emitted by at least one light source. The invention also discloses an image processing system.

Description

technical field [0001] The invention relates to a flashlight device, in particular to a flashlight device with adjustable brightness and illumination angle. Background technique [0002] Today's electronic devices (such as tablet computers, smart phones or notebook computers) are widely used in various fields, and these electronic devices are generally provided with a camera module and a flash module on the back of the electronic device. The user can execute the application program in the electronic device to control the camera module and the flashlight module to take pictures. However, generally, the output brightness of the flashlight module installed on the electronic device is not enough to cope with the dark scene, so that when the photo is taken in the dark scene, the captured photo will be unclear due to insufficient brightness. [0003] When encountering this situation, the general solution is to add a high-power flash device to the electronic device to emit stronge...
