Abstract
Disclosed are a display controlling method, a terminal, and a display device. The method includes the steps of capturing an image in a photographic area in front of a terminal in real time, calculating a user's eye blink frequency according to captured image, selecting a corresponding operation according to the eye blink frequency and a predetermined rule which relates to a corresponding relationship between the eye blink frequency and an operation, and controlling the terminal and the display device to execute a corresponding function according to the operation.
Claims14
A display controlling method, comprising the steps of:
- capturing an image in a photographic area in front of a terminal in real time;
- calculating a user's eye blink frequency according to the captured image;
- selecting a corresponding operation according to the eye blink frequency and a predetermined rule, and the predetermined rule relating to a corresponding relationship between the eye blink frequency and an operation;
- and
- controlling the terminal to execute a corresponding function according to the operation;
- wherein the step of calculating the user's eye blink frequency according to captured image comprises the steps of:
- fetching the image in a predetermined time period;
- identifying an eye image status in the image, and the eye image status including a closed eye status and an open eye status;
- incrementing the number of eye blinks by one, if the eye image status of two adjacent images is not the same;
- counting the number of eye blinks in the predetermined time period;
- and
- calculating the eye blink frequency according to the counted number of eye blinks and the predetermined time period.
