Fig. 3 shows the according to an embodiment of the invention schematic diagram of user's eye.
As shown in Figure 3, in order to understand exactly the user for the demand of terminal display effect, adopt the eye 302 to the user to carry out image acquisition in the present invention, and analyzed by the image to the eye 302 that collects, obtained the real-time size of user's pupil 306.
Particularly, when the user observes terminal screen for a long time, or external environment changes, and such as from the bright light to the light-off, under different situations, the user needs no display effect, just can obtain best reading, check experience.
Although under different situations, the size of user's pupil 306 can change, if but from the image collecting device of terminal, such as camera, eye 302 to the user carries out image acquisition, even in fact the size of pupil 306 does not change, but along with the variation of the distance of terminal and eye 302, the size of the pupil 306 in the image of collection also can be different.
But under different situations, the size of the iris profile 304 in the eye 302 is almost constant, therefore, and can be with the ratio of pupil 306 and iris profile 304 as the standard of judging user's pupil size.
Particularly, obtain the pupil diameter 308 (representing with d1) of the pupil 306 in the image, and the iris outline diameter 310 (representing with d2) that obtains iris profile 304, pupil state parameter β=d1/d2 then obtained.When the pupil diameter 308 of reality does not change, no matter then the distance of image collecting device and eye 302 is big or small, because the variation of same ratio also occurs iris outline diameter 310, the pupil state parameter β that then obtains can not change all the time, thereby avoids judging by accident.
Fig. 4 A to Fig. 4 B shows the schematic diagram that obtains according to an embodiment of the invention user's pupil size.
Shown in Fig. 4 A, be the embodiment that carries out image acquisition by the eye 402 of the 404 couples of users of camera on the terminal, and eye 402 is looked at cameras 404 straight at this moment.
In this case, camera 404 gathers the image information of eye 402, and the ocular imaging 406 that generates, and the pupil diameter 412 in the ocular imaging 406 and iris profile imaging diameter 414 correspond respectively to pupil diameter 408 and the iris outline diameter 410 of eye 402.
Suppose pupil diameter 408=L1, iris outline diameter 410=L2, pupil diameter 412=L3, iris profile imaging diameter 414=L4 then can obtain pupil state parameter β=L3/L4=L1/L2.
Shown in Fig. 4 B, when user's eye 402 was looked side ways camera 404, then eye 402 formed certain angles with camera 404, supposes that this angle is θ.At this moment, for the ocular imaging 406 that camera 404 generates, be not directly corresponding to eye 402, its pupil imaging diameter 420 and iris profile imaging diameter 422 correspond respectively to actual measurement pupil diameter 416 and actual measurement iris outline diameter 418.
Suppose the pupil diameter 408=L1 of eye 402, iris outline diameter 410=L2, actual measurement pupil diameter 416=L5, actual measurement iris outline diameter 418=L6, pupil imaging diameter 420=L7, iris profile imaging diameter 422=L8, then pupil state parameter β=L1/L2=(L1 * cos θ)/(L2 * cos θ)=L5/L6=L7/L8.
Before using pupil state parameter β, can determine several groups of states and parameter according to people's eye structure characteristics and pupil in the size under the different conditions first, variable diameter such as common people's pupil moves between 1.5-8.0mm, under the even in everyday situations at 2.5mm-5mm, and the about 12mm of the diameter of iris.Therefore, can be defined as follows from big to small four parameter: β according to the principle that pupil changes
Max, β
Up, β
DownAnd β
Min, then these four parameters form between a plurality of state areas, such as working as pupil state parameter β at β
Down-β
UpBetween the expression eyes of user in comfort conditions, do not need the display effect of terminal is regulated; When β at β
Min-β
MaxBetween and at β
Down-β
UpOutside expression user pupil begun initiatively expansion or shunk, need to regulate the display parameter of terminal, so that the user obtains more comfortable environment for use; When β at β
Min-β
MaxOutside expression user pupil be in extremely expansion or shunk, may cause to user's eyesight larger harm, can point out rest a period of time to the user.Certainly, when reality was used, concrete interval quantity, the threshold value between each interval all can be carried out free setting by manufacturer or user, to reach best experience effect.
Fig. 5 shows the particular flow sheet of adjusting according to an embodiment of the invention the terminal display effect.
As shown in Figure 5, adjust according to an embodiment of the invention the idiographic flow of terminal display effect as follows:
Step 504 is obtained user's eyes image and pupil diameter d1 wherein and iris outline diameter d2.Eyes image for the user who collects, at first need to pick out pupil and iris profile in the image, particularly, can process by image being carried out gray scale, then different position correspondences different gray scale display effects, then carries out the measurement of pupil diameter d1 and iris outline diameter d2.
Step 506 is calculated pupil state parameter β=d1/d2.Because along with image collecting device, such as camera, with the distance of eye, the variation of angle, the absolute diameter of the pupil that obtains all can change, thereby cause erroneous judgement.And when pupil changed, the iris profile in the outside can change hardly, thereby when pupil size variation did not occur, pupil diameter can not change with the ratio of iris outline diameter yet, thereby can be used as the basis for estimation of the size variation of pupil.
Step 508 judges whether β＞β 1.Before judging, processing, need to understand the actual change that pupil diameter may occur, variable diameter such as common people's pupil moves between 1.5-8.0mm, under the even in everyday situations at 2.5mm-5mm, and the about 12mm of the diameter of iris, therefore, can set in advance at least one numerical value change interval that β may occur.When β is changed to another numerical value interval from a numerical value interval, illustrate that then user's demand may change, need to carry out corresponding adjustment to the display effect of terminal.The β 1 here can be the endpoint value in β numerical value originally of living in interval and another numerical value interval.If β＞β 1, then enter step 510, otherwise enter step 518.
Step 510 judges that whether the hold time t of numerical value in new numerical value interval of β be greater than default time threshold T, if then enter step 512, otherwise enter step 520.Because when the user moves blink, visual angle change etc., may cause changing in moment of pupil or short time, but for these actions, be actually the variation that do not need to carry out display effect, therefore, if β is the variation of short time, the above-mentioned situation that belongs to is described, do not need to process, if β changes for a long time, then explanation need to be carried out the processing of display effect.
In addition, here for the judgement of holding time, can adopt special timer, also can count, such as when with fixed intervals eye being carried out image acquisition, the number of times that can recur to the numerical value of β the variation in numerical value interval adds up, when number of times reaches certain numerical value, holding time that same expression pupil size changes is longer, need to carry out the change of terminal display effect.
Certainly, this step 510 is not necessary, but after adding this step, obviously can avoid the disconnected generation of some erroneous judgements.
Step 512 is regulated the display effect of terminal.Particularly, when carrying out the adjusting of display effect, comprise that the size etc. of brightness that terminal is shown, contrast, tone, display text is regulated.
Step 514 judges whether β＞β max or β＜β min.Because there is certain normal variation scope in the size of pupil, when exceeding this normal variation scope, then explanation user's's this moment eye has been in the state of extremely expanding or shrinking, and is totally unfavorable to user's eyesight.
Step 518 judges whether β＜β 2.The β 2 here refers to the endpoint value in β originally residing numerical value interval and another numerical value interval, is another endpoint value that is different from β 1.If then enter step 510, otherwise enter step 520.
Step 520 is kept current display effect.That size at pupil does not change, changes is less, change in the situation such as shorter of holding time, and does not need the display effect of terminal is changed.
More than be described with reference to the accompanying drawings technical scheme of the present invention, consider that prior art all needs annex light source and imaging device, increase extra cost, be not suitable for being applied to portable terminal, and can't obtain preferably determine effect, therefore, the present invention proposes the control method of a kind of terminal and a kind of terminal display effect, can change according to user's pupil, display effect to terminal is regulated, so that the user obtains better view result, reduces as far as possible the injury to user's eye.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
