Embodiment
See also Fig. 1, be the synoptic diagram of electronic installation 10 of the present invention.Said electronic installation 10 comprises a luminescence unit 20, an image acquisition unit 30 and a processing unit 40 (as shown in Figure 2).This electronic installation 10 can be electronic installations such as e-book, digital photo frame, mobile phone.
Said luminescence unit 20 is used for sending infrared light beam towards electronic installation over against direction.Said image acquisition unit 30 is used to obtain and is positioned at the image of electronic installation over against the object of direction.
Said luminescence unit 20 comprises the LED lamp of two spaced sets in image acquisition unit 30 both sides; Said image acquisition unit 30 is a CMOS type camera.Said luminescence unit 20 is installed in the electronic installation 10 with image acquisition unit 30 and can carries out the adjustment of angle up and down.
Please consult Fig. 2 in the lump, said processing unit 40 comprises an image processing module 41, a computing module 42, a judge module 43 and a control module 44.
During towards electronic installation 1 positive, will produce bright spot during the infrared light beam irradiation people's that said luminescence unit 20 sends eyes as the people, 30 of said image acquisition units obtain image and then comprise the eyes bright spot.
Said image processing module 41 is used for 30 of analysis image acquiring units and obtains image and judged whether the eyeball bright spot, and obtains the position that obtains this eyeball bright spot and pupil center when the eyeball bright spot is arranged in the image at this.
Said computing module 42 is used for calculating the sight line vector that calculates eyes behind the CC position according to eyeball bright spot and pupil center, promptly calculates the direction of visual lines of eyes.Method according to eyeball bright spot and pupil center's calculating eye sight line vector specifically please refer to No. 20090015788 patented claim of the U.S..
Said judge module 43 is used to judge whether the sight line vector of eyes points to electronic installation 10.
Said control module 44 is used for getting into battery saving mode or normal mode of operation according to the judged result control electronic installation 10 of judge module 43; Promptly; When control module 44 judges that at this judge module 43 sight line vector of eyes is pointed to electronic installation 10; The expression user is just using this electronic installation 10 before electronic installation 10, keep electronic installation 10 in normal mode of operation this moment.When this judge module 43 judges that the sight line vector of eyes is not pointed to the display panel of electronic installation 10; And when the state continuance that the sight line vector of eyes is not pointed to electronic installation 10 was kept a period of time (for example 10 seconds), control electronic installation 10 got into battery saving modes.Wherein, under this battery saving mode, this electronic installation 10 stops to show or play operation.
Embodiment of the present invention also provides a kind of method that electronic installation 10 gets into battery saving mode of controlling.See also Fig. 3, this control method may further comprise the steps:
Step S301: launching infrared light beam and obtaining electronic installation the place ahead image towards electronic installation 10 over against direction.Specifically, luminescence unit 20 penetrates infrared light beam, simultaneously the place ahead image photographic of 30 pairs of electronic installations 10 of image acquisition unit.
Step S302: image processing module 41 obtains image according to 30 of image acquisition units and judges whether to detect the eyes bright spot.
If do not detect the eyes bright spot, execution in step S307 then, otherwise execution in step S303:
