1. A method for generating a high-dynamic range image, the method comprises:
determining to adjust a light intensity of a light source illuminating a scene to be captured by an image-capturing device in two upcoming image frames, wherein the light intensity is to be adjusted between the two upcoming image frames to be captured and wherein the determining is based on a determination that the dynamic range of the scene is larger than a threshold value;
instructing a controller of the light source to control the light source to output a first intensity of light while an image-capturing device captures a scene in a first upcoming image frame with a first exposure value setting influencing a first exposure value of an image sensor of the image-capturing device;
instructing the controller of the light source to control the light source to change from the first intensity of light to a second intensity of light such that the light source outputs the second intensity of light while the image-capturing device captures the scene with a second upcoming image frame with a second exposure value setting influencing a second exposure value of the image sensor, wherein
the second exposure value setting differs from the first exposure value setting,
the second intensity of light is higher than the first intensity of light when the second exposure value setting is higher than the first exposure value setting,
the second intensity of light is lower than the first intensity of light when the second exposure value setting is lower than the first exposure value setting, wherein a high exposure value setting corresponds to a high exposure value of the image sensor; and
stitching the first upcoming image frame with the second upcoming image frame into a high-dynamic range image frame.
