Abstract
A vehicle prompt apparatus and a corresponding method are provided. The method includes: acquiring an image recorded in real time by a designated terminal during driving; analyzing brightness distribution of the image and obtaining an analysis result; and when the analysis result is a first analysis result, communicating a warning message in accordance with a first prompting procedure, where the first analysis result indicates a vehicle light in the image. When other vehicles are present around the driving vehicle where the vehicle prompt apparatus is located, the acquired image may catch other vehicles' lights. By analyzing the brightness distribution in the image, when the analysis result indicates the presence of the vehicle lights, the driver can be prompted with the coming vehicle to improve the driving safety.
