Method for controlling fill light device with flash light
A recently granted patent (Publication Number: US11906878B2) outlines a method for controlling a fill light device that includes a flash light and a light guide. The method involves performing face detection on a preview image from a camera module, identifying the pupil position upon detecting a face, determining a light-shielding area of the light guide based on the pupil position, and calculating a light-emitting angle of the fill light device according to the distance between the capturing target and the device. By adjusting the shape and light-transmitting area of the light guide, the light-exiting area and light-emitting angle of the fill light device can be altered to enhance the quality of the captured image.
Furthermore, the patent describes the integration of a diastimeter for detecting the distance between the capturing target and the fill light device, allowing for precise determination of the light-emitting angle. The method also involves controlling the flash light to pre-flash at a preset power or continue lighting during the preview image acquisition process. Additionally, the light guide can be connected to a deformation driving assembly, comprising magnets, a coil, and a driving ring, to facilitate the deformation of the light guide based on the target light-emitting angle. This innovative technology aims to optimize the fill light device's performance by dynamically adjusting its parameters according to the specific capturing conditions, ultimately improving the overall image quality and lighting effects in photography scenarios.
