Based on above-mentioned application scenarios, embodiments provide a kind of tracking mode indicating means, this embodiment can be applied in the scene of 3D stereo image watching, be applied in the display unit possessing 3D Presentation Function, Fig. 2 is the flow chart of the tracking mode indicating means of the present embodiment, as shown in Figure 2, this embodiment can comprise:
201, track user facial information;
In this step 201, display unit can be followed the trail of user's face information by tracing equipment, such as, the view data gathering user's face by first-class image capture device of making a video recording realizes the tracking of user's face information, follows the tracks of or display unit is arranged several ultrasonic transmitter parts carry out user's face information trace by display unit configuring infrared sensing device etc. user's face information.Wherein, image capture device is including but not limited to camera, this camera can be wholely set with display unit, also can be the external camera be electrically connected with display unit, as long as can track user relative to the positional information of 3D display unit, by the annexation of camera and 3D display unit, the restriction to the embodiment of the present invention should be interpreted as.
In the Alternate embodiments adopting infrared ray sensing device to follow the tracks of user's face information, a line infrared sensor can be configured on the display apparatus, and in infrared sensor front, filter is set, filter arranges loophole, the infrared ray of the user's body radiation in display unit front can be sensed by the part infrared sensor in a line infrared sensor through described loophole, and display unit can according to the situation of change sensing infrared ray infrared sensor, analyze, to realize the tracking to user's face.
In addition, the mode configuring ultrasonic transmitter on the display apparatus can also be selected, user's face information is followed the tracks of, such as one or how many ultrasonic transmitters are set at the select location of display unit, by launching ultrasonic wave, and receive after ultrasonic wave runs into user's body and return display unit, utilize time and ultrasonic propagation velocity, calculate the position of user, and the facial information of user can be followed the tracks of by information such as hyperacoustic emission angles further.
It should be noted that, in the scheme of follow the tracks of face, usually to there is tracking range, this tracking range normally display unit can track a regional extent of user's head, and this scope is different and difference to some extent according to adopted tracing scheme.Such as carry out in the scheme of following the tracks of at employing image capture device, following range normally image capture device can gather the scope of image; And carry out in the scheme of following the tracks of at employing infrared sensor, following range can be the ultrared scope that infrared ray sensor can receive human body and sends.
202, when not tracking described user's face, generate abnormality indication information, this first abnormality indication information can not be tracked in order to characterize described user's face information;
Under normal circumstances, the reason that user's face information can not be tracked to has two kinds of situations:
The first is that user is in outside tracking range and causes user not to be tracked to, in this kind of situation, along with the difference of the tracer technique adopted, display unit has different tracking ranges, such as: when adopting image capture device to carry out face tracking, tracking range normally image capture device can collect the scope of user's face image; And adopting infrared sensor to carry out in the technology of user's face tracking, the scope that the infrared sensing device that the infrared ray of user's body radiation can be shown device configuration receives, is considered to tracking range usually; In similar ultrasonic wave tracer technique, hyperacoustic energy of launching of ultrasonic transmitter can the scope of radiation, then can be considered to the tracking range of this kind of technology.Usually, user is in tracking range, can both be tracked to.
The second is that user is in tracking range, but the situation that can not be tracked to.Such as, when adopting image capture device to carry out face tracking, because in environment, light intensity exceedes threshold value, cause user's face contour feature point not obvious, the user's face information caused can not be tracked to, or user's face is blocked by barrier (such as hair, sunglasses) etc., and the user's face information caused can not be tracked to; And when adopting infrared sensing device to carry out face tracking, there is in tracking range another interference source, also can launch infrared ray, causing the situation of the disturbed tracking failure caused of the infrared sensing device of display unit.
In this step, display unit generates abnormality indication information, prompting user, its facial information is not tracked to, wherein, abnormality indication information can be the combination of one or more modes in the modes such as prompt tone, LED light that loud speaker the produces light, graphic icons, photo or the text prompt that send, the mode of preferred graphic icons.
203, transmit described abnormality indication information to described user.
In this step, display unit according to the particular type of the first abnormality indication information, can be transmitted to user, such as, in loud speaker, send corresponding prompt tone, glimmered by LED or the appropriate location present graphical, icon, word etc. of display screen at display.
