Control method of terminal and terminal display effect

Abstract

The invention provides a terminal. The terminal comprises an image acquisition unit, an image processing unit and a display control unit, wherein the image acquisition unit is used for acquiring an image of the eyes of a user, the image processing unit is used for processing the image acquired by the image acquisition unit to obtain the size of the pupils of the user, and the display control unit correspondingly controls the display effect of the terminal according to the size of the pupils. Correspondingly, the invention further provides a method for controlling the display effect of the terminal. Through the technical scheme, the display effect of the terminal can be adjusted according to the variation of the pupils, so that the user obtains a better checking effect, and injury to the eyes of the user is lowered as much as possible.

Description

technical field [0001] The present invention relates to the technical field of terminal display, in particular, to a terminal and a method for controlling display effects of the terminal. Background technique [0002] The size of the pupil can control the amount of light entering the eye. Through the adjustment of the pupil, an appropriate amount of light can always enter the eye, so that the image of the object falling on the retina is clear without excessive light burning the retina. In the iris, two tiny muscles (the pupillary sphincter and the pupillary dilator) coordinate with each other to dilate and narrow the pupil (in addition to pupillary regulation, the different photoreceptor cells of the retina also respond to different brightness conditions). Like most vertebrates, human pupils are circular whether they expand or contract. The diameter of the pupil of ordinary people can vary between 1.5-8.0mm, and it can be less than 1mm and greater than 9mm in the case of ex...

Problems solved by technology

Existing image processing algorithms can determine the direction of gaze, but cannot determine the change of the pupil size of the user, because the distance and direction between the eyes and the imaging system will affect the final imaging of the pupil. In medicine, the position of the observed person needs to be fixed in order to observe pupil changes.

Considering the user's habits and environment, the distance and direction of the user when observing mobile terminals, tablet computers and other electronic devices will change at any time, and these existing technologies cannot meet the needs of monitoring pupil changes

In addition, these existing technologies require additional light sources and imaging devices, which increase additional costs and are not suitable for use in devices such as mobile terminals and tablet computers, and the long-term exposure of additional light sources to the eyes will also increase eye fatigue.

By determining the gaze direction, it can replace traditional input methods such as mouse keyboard or touch as input in some applications, which cannot reflect the user's reading experience and user experience.
