Embodiment one:
In the embodiment of the present application, a kind of information processing method is proposed.
Further, the method is applied to electronic equipment.
First, the electronic equipment in the embodiment of the present application is introduced.
Electronic equipment in the embodiment of the present application has display unit and image acquisition units, and display unit can use liquid crystal display 13 to illustrate, and image acquisition units can be camera 11.
Further, display unit sends the first polarized lightwave, and the polarization direction of the first polarized lightwave is the first polarization direction.
Concrete, when liquid crystal display 13 is at displaying contents, light wave can be sent, so that displaying contents is observed by user, the light wave now sent is then polarized lightwave, for user, this content can be watched, if but camera 11 now has a polaroid, if this polaroid can through light wave line of propagation vertical with the first polarized light wave line of propagation, so camera 11 just shooting less than any content about liquid crystal display 13.
Further, the position of image acquisition units is in the top of display unit, and image acquisition units has polaroid, and polaroid has the second polarization direction, and the second polarization direction is vertical with the first polarization direction.
Concrete, the position relationship of camera 11 and liquid crystal display 13 please refer to Fig. 1, and in FIG, the surface of liquid crystal display 13 has a depolarization sheet 12, and camera 11 is support by support, can photograph the full content that liquid crystal display 13 shows.
Further, the principle of depolarization sheet 12 is introduced below.
In some optical system, linearly polarized light is unwelcome, and such as in reflecting spectrograph, polarization effect can affect detector sensitivity.Depolarization sheet 12 is just used to polarized light to change into nonpolarized light, and it is widely used in Polarization-Sensitive system and instrument.
The method of depolarization is diversified, as diffuse reflection, optically-active, makes polarized light by scatter-type medium or the birefringent material etc. with Gradient Phase difference, then becomes nonpolarized light.Concrete, please refer to Fig. 2, Fig. 2 describes the principle of work of depolarization sheet 12.When polarized light is through depolarization sheet 12, polarized light can be become nonpolarized light by depolarization sheet 12, and the polarized light in Fig. 2 has certain directivity, and after it entered depolarization sheet 12, has then become the nonpolarized light of scatter-type.
But, when depolarization sheet 12 being placed on liquid crystal display 13 surperficial, depolarization sheet 12 only can work to the light wave transmitted through self, now, the first polarized light through depolarization sheet 12 will be converted to nonpolarized light, and the light wave of other positions is still polarized light.
Based on above-mentioned principle, the information processing method specific implementation process in the embodiment of the present application please refer to Fig. 3.
S301, when the surface of display unit is placed with depolarization sheet 12, gathers the first image by image acquisition units.

The second:
First image is processed, obtains the edge contour of the depolarization sheet 12 be present on the first image.
Based on the edge contour of depolarization sheet 12, depolarization sheet 12 is identified.
Concrete, except identifying the particular location of depolarization sheet 12 in liquid crystal display 13, the shape of depolarization sheet 12 can also be identified, the parameter informations such as size.
Due on the first image, only have depolarization sheet 12 content below can be caught on camera 11 and collect, so based on edge coordinate and the edge contour of this content, the edge contour of depolarization sheet 12 can be known.
Further, the depolarization sheet 12 in the embodiment of the present application is also transparent or translucent, and depolarization sheet 12 can adopt a lot of material to make, such as optics depolarization sheet 12, the other materials such as acrylic.
Above-mentioned steps has described the specific implementation process of information processing method, and the information processing method in the embodiment of the present application can be applied in multiple occasion, such as, play, online, reading electronic book etc.And; it can avoid electronic equipment when identifying the content after depolarization sheet 12; the interference of the other guide do not shown on the electronic equipment; like this; electronic equipment, when identifying the content of operation of user, can identify user faster in which kind of operation of use, and the efficiency identified can be very high; and not needing repeats to take pictures can identify the content of electronic equipment, and therefore the burden of electronic equipment can reduce.
