Abstract:
Provided are a photographing control method and system based on an external flash light source, and a storage medium. The method comprises: a first processing assembly controlling a working state of an internal flash light source and an image acquisition assembly according to a preset target brightness parameter, obtaining light ray state information of the internal flash light source and photographing state information of the image acquisition assembly under a corresponding working state, and generating an external light filling start trigger signal according to the light ray state information and the photographing state information, wherein the external light filling start trigger signal comprises a light filling start time; a signal sending assembly sending the external light filling start trigger signal to an external flash light source, so that the external flash light source starts illumination light filling work at the light filling start time according to the external light filling start trigger signal; and the image acquisition assembly starting photographing work after a flash illumination assembly starts the illumination light filling work. In the present invention, under the premise of not changing device software and hardware, an external flash light source is synchronously controlled to perform illumination light filling during exposure, thereby improving the quality of photographing.
