Problems solved by technology

[0003] When the flashlight is turned on to take pictures, if the subject is a person, then, due to the instantaneous flash of the flashlight, the person being photographed is likely to blink because of the strong light from the flashlight. Shooting, not only wastes the power of the camera equipment, but also easily reduces the photographer's enthusiasm for taking pictures

Abstract

The invention discloses a flashlight intensity control method and an image pickup device. The flashlight intensity control method includes starting a flashlight pickup mode of the image pickup device; in the flashlight pickup mode, if detecting human faces, acquiring a coordinate area where the human faces are in the image pickup device; if the coordinate area where the human faces are in the image pickup device is larger than a preset area, and setting current intensity of a flashlight according to the coordinate area where the human faces are in the image pickup device, wherein the current intensity of the flashlight is in negative correlation to the coordinate area where the human faces are in the image pickup device; starting the flashlight of the image pickup device according to the set current intensity of the flashlight for filling light. By the flashlight intensity control method, image pickup quality can be effectively improved.

Description

technical field [0001] The invention relates to the field of photographing, in particular to a flash light intensity control method and photographing equipment. Background technique [0002] A flashlight is a photographic accessory that can emit strong light in a short period of time. At present, most camera equipment (such as card cameras, SLR cameras, mobile terminals with camera functions, etc.) Instant lighting in dark situations, or partial fill light for the subject in bright light situations. [0003] When the flashlight is turned on to take pictures, if the subject is a person, then, due to the instantaneous flash of the flashlight, the person being photographed is likely to blink because of the strong light from the flashlight. Shooting not only wastes the electric energy of the camera equipment, but also easily reduces the photographer's enthusiasm for taking pictures. Contents of the invention [0004] The invention provides a flash light intensity control met...
