Embodiment
Below in conjunction with drawings and embodiments, the present invention is described in detail.
Refer to Fig. 1, Fig. 1 is the structural representation of mobile terminal first execution mode of the present invention.This mobile terminal 10 comprises:
Tracing of human eye module 110, for obtaining eyes of user position;
Wherein eyes of user position is the eyes of user relatively orientation angles of the display screen of this mobile terminal 10 and distance, and for the user of diverse location when observing same stereoscopic display screen, the stereo scene viewed is different because of the difference of its position.
Holography conversion module 120, for being the holographic three-dimensional scene comprising left and right view according to eyes of user position by virtual three-dimensional scene conversion;
Wherein virtual three-dimensional scene includes but not limited to the virtual three-dimensional scenes such as existing 3D game, 3DCG animation.Virtual three-dimensional scene conversion is holographic three-dimensional scene by this holography conversion module 120, treatment image is enriched, the moving object more attractive that more single metallic plate, glass bar or content are fixing, the enthusiasm that adding users is corrected defects of vision and recreational.In addition this holography conversion module 120 is according to the conversion of eyes of user position, makes the holographic three-dimensional scene be converted to obtain good stereos copic viewing effect in eyes of user position.
Scene adjustment module 130, for monitoring or receive the depth of field of this holographic three-dimensional scene, and transmission regulates the instruction of the depth of field to this holography conversion module 120;
Wherein regulate the instruction of the depth of field to comprise current depth of field numerical value become large or diminish and the information such as concrete variable quantity or comprise the depth of field is adjusted to the information that one determines numerical value;
The depth of field wherein in the present invention and variable quantity parallax thereof represent.Depth of field numerical value be on the occasion of time, represent that this holographic three-dimensional scene is close shot, visually this holographic three-dimensional scene protrudes from the display screen display of this mobile terminal 10; When depth of field numerical value is negative value, represent that this holographic three-dimensional scene is distant view, visually this holographic three-dimensional scene is depressed in the display screen display of this mobile terminal 10; When depth of field numerical value is 0, represent that this holographic three-dimensional scene is plane and is attached to the display screen display of this mobile terminal 10.The absolute value of this depth of field less i.e. depth of field numerical value of larger or negative value numerical value on the occasion of numerical value is larger, and protrude or be depressed in the close shot of this holographic three-dimensional scene on the display screen of this mobile terminal 10 or the distant view depth of field is more greatly that close shot is nearer, distant view is far away; The absolute value of this depth of field more i.e. depth of field numerical value of less or negative value numerical value on the occasion of numerical value is less, protrude be depressed in the close shot of this holographic three-dimensional scene on the display screen of this mobile terminal 10 or the less i.e. close shot of the distant view depth of field comparatively far away, distant view is nearer.In other embodiments, optional do not represent the depth of field and variable quantity thereof with parallax or be not 0 with the depth of field time represent that holographic three-dimensional scene is plane and is attached to the execution mode of the display screen display of this mobile terminal 10.
The depth of field of wherein monitoring this holographic three-dimensional scene refers to that the depth of field of monitoring current holographic three-dimensional scene is a certain numerical value, sends and regulates the instruction of the depth of field to be used for current depth of field numerical value to become large or the predetermined value that diminishes; Or receive the depth of field determining numerical value, no matter why the current depth of field is worth, all also send according to zooming in or out the depth of field numerical value after certain multiple using the depth of field numerical value received the instruction regulating the depth of field as the depth of field after adjustment, as in the first moment, send and regulate the instruction of the depth of field to be used for holographic three-dimensional scene being the first numerical value in the depth of field numerical value change in the first moment, in the second moment, send and regulate the instruction of the depth of field for holographic three-dimensional scene being become large in the depth of field value (as the first numerical value) in the second moment or being second value after diminishing.
Further, this scene adjustment module 130 also for monitoring is set or receive the depth of field the time interval or and regulate depth of field amplitude of variation (there is identical meaning with the variable quantity in the present invention, predetermined value), make far-near or near-far away change of holographic three-dimensional scene realize slowly change or change suddenly.When wherein holographic three-dimensional scene slowly changes, having depth of field change can not be too fast, and then can not cause the dizzy, tired of eyes of user.
This holography conversion module 120 also for receiving the instruction of this adjustment depth of field, and adjusts the depth of field of this holographic three-dimensional scene, and object distance in this holographic three-dimensional scene far or is closely changed;
Even if wherein in this holographic three-dimensional scene, object distance refers to that in this holographic three-dimensional scene, object is presented on the display screen of this mobile terminal 10, but in this holographic three-dimensional scene, object is actually the object distance of eyes of user viewing object.As in scene holographic three-dimensional on the display screen of mobile terminal 10, the object distance of certain object is 1 meter, be then equivalent to certain object that eyes of user watches about 1 meter of, front, instead of refer to the display location of this mobile terminal 10 in human eye front 1 meter of.In holographic three-dimensional scene provided by the invention, object distance includes but not limited to it is any numerical value of 1 meter.
Wherein the depth of field numerical value of this holographic three-dimensional scene is larger, makes object distance in this holographic three-dimensional scene nearer; Wherein the depth of field numerical value of this holographic three-dimensional scene is less, makes object distance in this holographic three-dimensional scene far away.
