Embodiment
Below in conjunction with drawings and embodiments, the present invention is described in detail.
Refer to Fig. 1 a, Fig. 1 a is the structural representation of mobile terminal first execution mode of the present invention.This mobile terminal 10 comprises:
Tracing positioning apparatus 110, for obtaining the positional information of at least two observers;
Angle adjustment circuit 120, for utilizing the positional information of each observer, calculating and obtaining corresponding ray cast angle and right and left eyes viewpoint stereo-picture;
Holographic three-dimensional display screen 130, the beam projecting angle of this holographic three-dimensional display screen is adjusted for timesharing, the ray cast angle of the corresponding each positional information of the light of this holographic three-dimensional display screen outgoing is projected, and the right and left eyes viewpoint stereo-picture of the light projected corresponding relevant position information.
Wherein this mobile terminal is selected from but is not limited to the mobile phone, flat board, palmtop PC etc. that are convenient for carrying.Fixed cellular terminal such as motion picture screen, computer screen or large-scale exhibition screen is also suitable for timesharing display stereo-picture or video in other embodiments.
Wherein the positional information of observer specifically observer relative to the orientation angles of this holographic three-dimensional display screen 130 and distance, for the observer of diverse location when watching same holographic three-dimensional display screen, the right and left eyes viewpoint stereo-picture (or referred to as visual point image) viewed is different because of the difference of its position.
Consult Fig. 1 b, Fig. 1 b is the principle schematic of existing bore hole formula stereo display technique, some sub-visual point images are synthesized in a two field picture, pass through grating, Fig. 1 b example is that lenticulation 1310 is left accordingly by it, right eye visual point image projects a left side respectively, right eye, for two observers 111 and the observer 122 of diverse location, it sees the obvious right and left eyes viewpoint stereo-picture of relevant position respectively, but when one of them observer moves as observer 111, even if the parameter of adjustment lenticulation 1310 makes this observer 111 have the angle of best viewing stereo-picture, but because the synergy of lenticulation 1310, the beam projecting angle of visual point image is determined in position after foundation observer 111 moves, for Orientation observation person 122, then may not the obvious stereo-picture of view result.Namely existing tracking mode grating stereo Display Technique makes multiple user when observing same three-dimensional display, when one of them observer move and tracking display time, can be affected other fix or the viewing stereoeffect of mobile observer, make other observers can not watch the image of obvious stereoeffect.
Consult Fig. 1 c, Fig. 1 c is holographic three-dimensional display 130 multiple views display schematic diagram.There is shown the observer of 4 diverse locations, i.e. observer 1, observer 2, observer 3 and observer 4, timesharing adjusts the beam projecting angle of this holographic three-dimensional display screen 130, make the ray cast angle of the positional information of the corresponding observer 1 of the light of outgoing project in the first moment, and the right and left eyes viewpoint stereo-picture (visual point image that in figure, observer 1 views) of the light projected corresponding relevant position information.In like manner, second moment, adjust the beam projecting angle of holographic three-dimensional display screen 130, the ray cast angle of the positional information of the corresponding observer 2 of the light of outgoing is projected, and the right and left eyes viewpoint stereo-picture (visual point image that in figure, observer 2 views) of the light projected corresponding relevant position information, in like manner observer 3 and observer 4 have identical type of action, repeat no more herein.It should be noted that, in Fig. 1 c, 4 observers are only example explanation, and in other embodiments, the number of observer at least 2, not being limited to is 4 or other concrete numbers.
Wherein holographic three-dimensional display screen 130 particularly adjusts the beam projecting angle of this holographic three-dimensional display screen in chronological order respectively, the ray cast angle of the positional information of the corresponding each observer of the light of outgoing is projected, and the right and left eyes viewpoint stereo-picture of the light projected corresponding relevant position information.The holographic three-dimensional display of this holographic three-dimensional display screen 130 timesharing is the residual visual effect based on eye, and namely the eyes of people are after viewing one width picture, and its impression just can disappear after retaining about 1/10 second in the brain.If the time interval that two width pictures alternately occur, namely timesharing interval is less than 1/10 second, human eye thinks psychologically it is seen that a width picture, right and left eyes viewpoint stereo-picture is projected to the left eye of every observer and the right eye of every observer respectively on the interval being less than 1/10 second, then timesharing can realize the holographic three-dimensional display of many people multi-angle to the light that the observer of diverse location carries out projecting corresponding visual point image.In other embodiments, optionally first right and left eyes viewpoint stereo-picture is projected the right and left eyes into same observer respectively, then the right and left eyes viewpoint stereo-picture of diverse location is projected to the observer of relevant position by timesharing respectively.
Wherein when observer moves, the positional information of tracing positioning apparatus Real-time Obtaining observer, and ray cast angle and the right and left eyes viewpoint stereo-picture of relevant position information is obtained by angle adjustment circuit counting, finally by holographic three-dimensional display screen timesharing and in real time adjustment beam projecting angle, makes the ray cast of outgoing corresponding right and left eyes viewpoint stereo-picture to the observer of corresponding correspondence position information.
Be different from the situation of prior art, first the mobile terminal that present embodiment provides obtains the positional information of at least two observers by tracing positioning apparatus, next utilizes the positional information of each observer to obtain corresponding ray cast angle and right and left eyes viewpoint stereo-picture by angle adjustment circuit counting, last timesharing adjusts the beam projecting angle of holographic three-dimensional display screen, the ray cast angle of the corresponding each positional information of the light of this display screen outgoing is projected, and the right and left eyes viewpoint stereo-picture of the light projected corresponding relevant position information, make multiple user when observing same holographic three-dimensional display with existing tracking mode grating stereo Display Technique, when one of them observer move and tracking display time, the technology that can affect the stereoeffect that other are fixed or mobile observer watches is compared, when present embodiment makes multiple observer watch same holographic three-dimensional display screen simultaneously, even if one of them observer moves and the good three-dimensional image of tracking display, the image that other observers watch obvious stereoeffect is not affected yet, more convenient people use the daily mobile terminal carried to carry out real-time volume viewing, improve Consumer's Experience.
