Terminal and method for controlling display effect of terminal

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 field of terminal display technology, and in particular to a terminal and a method for controlling terminal display effects. 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, there are two small muscles (the pupillary sphincter and the pupil dilatus) that coordinate with each other to complete pupil dilation and contraction (except pupil adjustment, different photoreceptor cells of the retina also play a role in different brightness conditions). Like most vertebrates, the pupils of humans are round whether they dilate or shrink. The diameter of the pupil of the average person can vary between 1.5-8.0mm, and can be less than 1mm and greater than 9mm in the ca...

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.
