Method for determining semi-synchronous exposure parameters and electronic device

Abstract

The embodiment of the invention discloses a method for determining semi-synchronous exposure parameters and an electronic device, which are used for well balancing the image effect and the splicing effect of a multi-lens panoramic camera, and providing an EV limit value set by a user so that the user can control the exposure effect according to the environment and the requirements of the user. Themethod disclosed by the embodiment of the invention comprises the following steps: acquiring a first exposure parameter corresponding to each lens; if it is determined that the preset EV limit valueis not met according to the first exposure parameters of each lens and the adjacent lens, respectively calculating to obtain an exposure control parameter of each lens; calculating to obtain a secondexposure parameter corresponding to each lens according to the exposure control parameter of each lens and the first exposure parameter corresponding to each lens; and if it is determined that the preset EV limit value is met according to the second exposure parameters of each lens and the adjacent lens, determining the second exposure parameter corresponding to each lens as the semi-synchronous exposure parameter of each lens.

Description

technical field [0001] The invention relates to the field of imaging, in particular to a method for determining semi-synchronous exposure parameters and an electronic device. Background technique [0002] In the existing technical scheme of synchronous automatic exposure for multi-lens panoramic cameras, the method of synchronous automatic exposure is to comprehensively consider the ambient brightness corresponding to each lens, and calculate a set of exposure parameters that tend to be centered, and all lenses use this exposure parameter. [0003] However, in scenes with high light contrast, it is not very reasonable to use the same exposure parameters for all shots. For example, on the side of the window, the exposure parameter obtained by the synchronous automatic exposure method is a middle value, which will cause the lens facing the outside of the window to be overexploded, and the lens facing the interior to be underexploded.

[0003] However, in scenes with large light contrast, it is not very reasonable to use the same exposure parameters for all shots

For example, on the side of the window, the exposure parameter obtained by the synchronous automatic exposure method is a middle value, which will cause the lens facing the outside of the window to be overexploded, and the lens facing the interior to be underexploded.
