Embodiment
The first embodiment
Fig. 1 illustrates the 3 D image display system 10 according to one embodiment of the invention.Please refer to Fig. 1,3 D image display system 10 comprises a display unit 100, and display unit 100 is for example the display unit of switchable type two-dimensional/three-dimensional, comprises a processing unit 102, start unit 104, display unit 106 and image acquisition unit 108.Processing unit 102 is to be electrically connected start unit 104, display unit 106 and image acquisition unit 108.Processing unit 102 can comprise storage element 1020, signal generation unit 1022, calculation unit 1024 and driver element 1026.Driver element 1026 is in order to provide a driving signal to display unit 106.
In this embodiment, start unit 104 can be in order to carry out a triggering step, to start the 3-dimensional image function of display unit.For instance, start unit 104 can comprise a button or touch-control button, in the time that user presses button or touch-control button, can start the 3-dimensional image function of display unit.Or start unit 104 also can, by the remote signal that receives remote controller to start 3-dimensional image function, not be particularly limited.
In an embodiment, can also use active formula lens (Active Lens) to reach 2D/3D Presentation Function switches, it is to utilize a lens jacket to arrange in pairs or groups a liquid crystal panel (for example TN type liquid crystal panel) as optics regulation and control module, liquid crystal panel can offset the refraction effect of lens jacket for light through designing in the time that 2D operates, make the light that penetrates display module not be subject to optics to regulate and control the impact of module, normally show 2D image.In the time that 3D operates, active formula lens have the effect of lens pillar.In addition, in another embodiment, can also replace optics regulation and control module with the staggered general grating paster of general lens pillar paster or transparent area and coating shading region, not be restricted.But, this type of being without changing the grating of function or the display unit of lens pillar paster and cannot changing its kenel, therefore and the three dimensional display capabilities of having no way of switch to two-dimentional Presentation Function.
Figure 1B illustrates the schematic diagram that shows bearing calibration according to the 3-dimensional image of one embodiment of the invention.Please also refer to Figure 1A～1B, display unit 100 has display unit 106, in order to show a correcting pattern.Correcting pattern can comprise reference images P1 and a contraposition image P2.In an embodiment, image acquisition unit 108 is first to confirm that user's initial information H(is for example the initial position of a gesture).Now, the result that user can watch according to sight line, judge show contraposition image P2 whether in tram with correct imaging.In the time of contraposition image P2 malposition, user can provide a correction instruction (being for example action or gesture) by corresponding reference images P1, carries out an aligning step.
For instance, as shown in Figure 1B, image acquisition unit 108 is first confirmed initial information H.In this embodiment, reference images P1 is for example the cross of a hollow, and contraposition image P2 is for example the cross of a solid line, but is not limited to this, and reference images P1 and contraposition image P2 can be also that other shapes, pattern or the mode with color present.When contraposition image P2 representative cross be arranged on the hollow of reference images P1 representative cross in intracardiac, represent that image has correct imaging.When contraposition image P2 representative cross be not arranged on the hollow of reference images P1 representative cross in intracardiac, user can utilize action or the mode such as gesture to provide correction instruction to adjust contraposition image P2, the hollow that makes it be arranged on reference images P1 representative cross in intracardiac.Meanwhile, image acquisition unit 108 can capture user's correction instruction.
Then, image acquisition unit 108 can export correction instruction and initial information H to processing unit 102.Processing unit 102 compares after correction instruction and initial information H, can obtain an adjustment message, and adjusting message is for example to move displacement and the direction of contraposition image P2 with a direction.In the time that reference images P1 and contraposition image P2 are the form of color, adjusting message can be the color range of RGB.Because correction instruction is benchmark image P1 and instruction that at present comparison of the shown image information of display unit 106 is made, therefore, adjusting message also can be with reference images P1 and the comparative result of the shown image information of display unit 106 is relevant at present.
Cannot be successfully completed timing when carrying out aligning step once, can multiple aligning step, now, processing unit 102, after aligning step repeatedly, can obtain multiple adjustment messages.Processing unit 102 can add the General Logistics Department by these a little adjustment messages and obtain proofreading and correct result.Then, user can judge that whether correction result is correct according to viewed image, or the processing unit that also can show by 3-dimensional image is done judge.When judgement is proofreaied and correct result when correct, calculation unit 1024 produces one and results according to proofreading and correct result again, and according to the image resulting in after output calibration to display unit 106.
In an embodiment, can, according to user in the time that different angles are watched display unit 106, converse the deformation relationship of reference images P1 and contraposition image P2.When the central vertical direction that departs from display unit 106 as user is viewed and admired picture, can depart from according to user the angle of display unit 106, extrapolate the deformation relationship of reference images P1 and contraposition image P2, and the mode that should proofread and correct of corresponding this deformation relationship, according to the correcting mode of different angles, processing unit 102 can correspondingly produce correction instruction.Certainly, the visual experience that user also can be when viewing and admiring, directly provides correction instruction.Therefore, the disclosed correcting mode of embodiments of the invention, can reach optimized calibration result for user's the angle of viewing and admiring, to produce correct three-dimensional display effect.In the correct three-dimensional display effect described in this, can be that user adjusts setting according to visual experience, or the default display effect of processing unit 102.
Below explanation calculation unit 1024 is produced to the method resulting in.Please refer to Fig. 2 A, it illustrates according to the schematic diagram of the pattern of the Pixel Information of the display module 120 of one embodiment of the invention and optics regulation and control module 140 (getting a matrix part represents).As shown in Figure 2 A, optics regulation and control module 140 can show the periodicity grating pattern forming that is staggered by transparent area C and shading region B, for example, be one stepped (step) cycle graph.Certainly,, in other embodiment, the arrangement mode of transparent area C and shading region B can also be linear pattern (stripe) or bias type (slant), is not restricted.In Fig. 2 A, position X2 represents transparent area C and the corresponding horizontal x axle of the shading region B absolute position numbering of optics regulation and control module 140.In addition, position X1 represents that the corresponding horizontal x axle of the Pixel Information of display module 120 absolute position numbering, color layer CF represent corresponding red (R) green (G) indigo plant (B) color showing of Pixel Information institute.Explain with 8 visual angles in this embodiment system, certainly, various visual angles (multi-view) display unit that embodiments of the invention can be greater than 2 for any visual angle number n, does not limit.
