Abstract
The invention discloses a camera device that contains an image capture module for capturing image data including a user; an information processing module for obtaining human face image data from the image data, and obtaining a distance information between a human face corresponding to the human face image data and the camera device according to the human face image data; a decision module for determining whether the distance corresponding to said distance information is less than a predetermined value, and generating a prompt information while the distance corresponding to said distance information is less than a predetermined value; and a prompt output module for outputting said prompt information based on said distance information, said prompt information is configured to give a prompt to said user. The invention also discloses an information prompt method. The technical solution of the present invention can obtain and output a distance between a human face and the camera device, so as to prevent and prompt that a user is too close to a display screen, and thereby protect eyesight of the user.
