Abstract

The invention is suitable for the electronic terminal technical field, and discloses a title photographing and searching method and device. The method comprises the following steps starting a camera, and a light emitting device so as to project the light emitted by the light emitting device on the shooting main body of the camera; clipping the title image where light projection points of the light emitting device are located in the image shot by the camera; and completing title searching based on the title image to obtain the answer to the title. The method determines the position of a title in an image through light projection points so as to allow a terminal background to automatically complete title image clipping, thereby improving title photographing and searching operation efficiency.
