Imaging control method and device, and imaging control system

Abstract

An imaging control method and device, and an imaging control system, the method comprising: acquiring imaging data of an imaging system under ambient light conditions, acquiring imaging data of the imaging system under a first flash condition; based on the first coefficient and the second coefficient, determining The imaging control parameter of the imaging system under the second flash condition, the imaging control parameter includes at least one of exposure time, gain parameter and white balance parameter; the first coefficient is the imaging data under the first flash condition and the ambient light condition The scaling factor of the imaging data, the second coefficient is the proportional coefficient of the light output amount of the first flash condition and the light output amount of the second flash condition; the light output amount under the second flash condition is greater than the light output amount under the first flash condition . The time for maintaining the brightness of the flashlight at the second flashing condition can be reduced, the loss of the flashlight can be effectively reduced, and auxiliary components such as a range finder are not needed, the hardware cost can be effectively reduced, and it is easy to implement on a mobile terminal.

Description

technical field [0001] The invention relates to the field of digital technology, in particular to an imaging control method and device, and an imaging system. Background technique [0002] With the rapid popularization of imaging equipment such as high-resolution digital cameras and smart phones, users have higher and higher requirements for imaging quality. Precisely controlling the imaging control parameters of imaging equipment has become an important means to improve the final imaging quality. The imaging control parameters of the imaging device generally include exposure time, gain parameters, white balance parameters and the like during imaging. The exposure is a physical quantity used to describe the luminous flux from the scene to be photographed to the imaging device. When the imaging device is automatically exposed, the imaging device can automatically adjust the exposure according to the intensity of the shooting light to prevent the image from being overexposed o...
