System and method of controlling camera flash lamp shooting

Abstract

A method for controlling a flash of an electronic device by detecting an illumination intensity and a color temperature of a current environment from a RGB sensor. When the illumination intensity is lower than a first predetermined value, a pre-flash of the flash is turned on. Control a color temperature of the pre-flash to be equal to the color temperature when the color temperature is lower than a second predetermined value. A distance between a target object and the camera is obtained, adjusting the current of the high color temperature LED and the current of the low color temperature LED simultaneously according to the obtained distance after turning on a main-flash of the flash to capture an image of the target object.

Description

technical field [0001] The invention relates to a system and method for controlling a flashlight of a camera to take pictures. Background technique [0002] At present, the brightness and color temperature of the flash of mobile phone cameras are fixed, and will not change with the intensity of ambient light, the distance of the object to be photographed, and the color temperature of ambient light. It always fills the camera with a fixed brightness and a fixed color temperature during the shooting process, so in some situations, the camera needs a flash to fill in light, and the effect is not good, for example, when the subject is close to the subject in a dark environment When using the flash light, the photo will be exposed because it is too bright; when using the flash light in a dark environment and the distance from the subject is far away, the light will be insufficient because the brightness is too dark, and no clear photos can be taken; When taking pictures under th...

It always fills the camera with a fixed brightness and a fixed color temperature during the shooting process, so in some situations, the camera needs a flash to fill in light, and the effect is not good, for example, when the subject is close to the subject in a dark environment When using the flash light, the photo will be exposed because it is too bright; when using the flash light in a dark environment and the distance from the subject is far away, the light will be insufficient because the brightness is too dark, and no clear photos can be taken; When taking pictures under the light source, because the ambient light is a warm-colored light source, but the flash still uses cold-colored light to fill in the light, so the color fades after taking pictures with a mobile phone camera, and it is impossible to take good photos that match the current situation.
