Abstract

The invention discloses a method and device for adjusting cursor size of an electronic terminal, wherein the method comprises the steps of starting a camera and a light emission device when a trigger instruction for searching questions is received, so that the cursor emitted by the light emission device is projected onto the shooting subject of the camera; detecting the included angle of the camera relative to the horizontal direction or the vertical direction through the process that the cursor determines the shooting subject, and adjusting the cursor size according to the detected included angle. According to the method and device for adjusting the cursor size of the electronic terminal, the cursor size can be adjusted according to the variation of the angle of the camera.

Description

technical field [0001] The present invention relates to the technical field of electronic terminals, in particular to a method and device for adjusting the size of a cursor in an electronic terminal. Background technique [0002] At present, many electronic education products on the market have the function of taking photos and searching for questions. Users control the camera of the electronic terminal to take pictures of the questions in the books. At present, some products on the market use the cursor sent by the electronic terminal to determine the shooting position. However, the size of the existing cursor is fixed and cannot be adjusted according to the size of the subject (such as words or test questions), which is not convenient for users to operate and affects positioning accuracy. [0003] Therefore, it is necessary to propose a new technical solution to solve the above technical problems. Contents of the invention [0004] In view of this, the present inventio...
