Below will explain content of the present invention by embodiment, embodiments of the invention not must any specific environment, application or particular form as described embodiments can be implemented in order to limit the present invention.Therefore, about the explanation of embodiment, be only explaination purpose of the present invention, but not in order to limit the present invention.Should be noted that, in following examples and accompanying drawing, with the non-directly related element of the present invention, omit and do not illustrate; And in accompanying drawing, each interelement size relationship is only for asking easy understanding, non-in order to limit actual ratio.
First embodiment of the invention please also refer to Fig. 1, Fig. 2 A, Fig. 2 B and Fig. 2 C.The schematic diagram that Fig. 1 is an image projecting system 1.The right and left eyes test pattern that Fig. 2 A is image projecting system, right and left eyes synchronizing signal, left eyeglass penetrance and right eyeglass penetrance are in the schematic diagram of temporal variation.The schematic diagram of the light leak rate value that Fig. 2 B is right and left eyes synchronizing signal and correspondence thereof.The schematic diagram that Fig. 2 C is right and left eyes test pattern of the present invention.
Image projecting system 1 comprises projector's 110, one active solid (Stereoscopy) glasses 120 and a luminance meter 130.Projector 110 is a stereoscopic image projector, and projects a right and left eyes test pattern 210 according to a sequential, and wherein the left eye test pattern that left eye is received is wanted in the L representative, and the right eye test pattern that right eye is received is wanted in the R representative.In the present embodiment, sequential be take 1/120 second as a unit, and in the right and left eyes test pattern 210 that projector 110 projects, left eye test pattern L and right eye test pattern R occur alternately with the frequency of 120 hertz.In the right and left eyes test pattern 210 of projection, projector 110 is more according to timing sequence generating one standard right and left eyes synchronizing signal 220.The frequency of standard right and left eyes synchronizing signal 220 is 60 hertz.
Described in prior art one joint, required reaction time (reactive time on penetrate in switching/shielding status of active stereo glasses; RT) (10-3 second, ms), so projector 110 need add in the front of each image time (the dark time of the black picture of the preceding paragraph projection to be about 2 ~ 3 milliseconds; DT), reduce the right and left eyes interactive interference.Yet, in fact, signal transmission and process the delay caused, will cause the received synchronizing signal of active stereo glasses 220 have a delay time T(as the right and left eyes synchronizing signal 220 of Fig. 2 ' as shown in).Therefore, the actual right and left eyes synchronizing signal 220 received ' the clock pulse phase place can't be with the right and left eyes image display of stereopsis the coupling of the sequential on screen.In in the case, project the time D T that deceives picture and can't be overlapped in the reaction time RT(of left eyeglass 122 and right eyeglass 124 fully as shown in actual left eyeglass penetrance 230 ' and actual right eyeglass penetrance 240 '), thereby produce the right and left eyes interactive interference.
For solving the above problems, projector 110 of the present invention is adjusted synchronizing signal 220.Please refer to Fig. 2 B, projector 110 is according to timing sequence generating standard right and left eyes synchronizing signal 220 and a plurality of right and left eyes synchronizing signal 220A, 220B, 220C, 220D, 220E, 220F.Each right and left eyes synchronizing signal 220A, 220B, 220C, 220D, 220E, 220F produce via the phase place that changes standard right and left eyes synchronizing signal 220, and right and left eyes synchronizing signal 220A, 220B, 220C, 220D, 220E, 220F are respectively standard right and left eyes synchronizing signal 220 delay t1, t2, t3, t4, t5 and t6.In the present embodiment, t1, t2, t3, t4, t5 and t6 are respectively-150 microseconds (μ s) ,-100 microseconds ,-50 microseconds, 50 microseconds, 100 microseconds and 150 microseconds.
Then, projector 110 is respectively by respectively this right and left eyes synchronizing signal 220A, 220B, 220C, 220D, 220E, 220F and standard right and left eyes synchronizing signal 220 are sent to active stereo glasses 120.Simultaneously, projector 110 is according to sequential projection right and left eyes test pattern 210.120 of active stereo glasses are operated according to each right and left eyes synchronizing signal 220A, 220B, 220C, 220D, 220E, 220F and 220 pairs of left eyeglasses 122 of standard right and left eyes synchronizing signal and right eyeglass 124 one by one.
When active stereo glasses is operated according to each right and left eyes synchronizing signal 220A, 220B, 220C, 220D, 220E, 220F and 220 pairs of left eyeglasses 122 of standard right and left eyes synchronizing signal and right eyeglass 124, the luminance meter 130 that is connected to projector 110 is measured left eyeglass brightness value L-V and right eyeglass brightness value R-V by left eyeglass 122 and right eyeglass 124 respectively.In other words, luminance meter 130 measures under corresponding different right and left eyes synchronizing signals, penetrates the brightness value of the right and left eyes test pattern 210 of left eyeglass 122 and right eyeglass 124.Afterwards, luminance meter 130 is sent to projector 110 by these left eyeglass brightness value L-V and right eyeglass brightness value R-V.Projector 110 is according to each left eyeglass brightness value L-V, calculating is corresponding to the left eyeglass light leak rate value CL of the left eyeglass 122 of each right and left eyes synchronizing signal 220A, 220B, 220C, 220D, 220E, 220F and standard right and left eyes synchronizing signal 220, and, according to each right eyeglass brightness value R-V, calculate the right eyeglass light leak rate value CR corresponding to the right eyeglass 124 of each right and left eyes synchronizing signal 220A, 220B, 220C, 220D, 220E, 220F and standard right and left eyes synchronizing signal 220.
Particularly, right and left eyes test pattern 210 comprise a left eye black/the white test pattern of right eye, a left eye be white/the black test pattern of right eye and a left eye black/the black test pattern of right eye, as shown in Figure 2 C.For each right and left eyes synchronizing signal 220A, 220B, 220C, 220D, 220E, 220F and standard right and left eyes synchronizing signal 220, luminance meter 130 by left eyeglass 122 out of the ordinary measure left eyes white/the black test pattern brightness value YL of right eye
LWRB, a left eye is black/the white test pattern brightness value of right eye YL
LBRWAnd the black test pattern brightness value YL of a deceive/right eye of left eye
LBRB, its left eyeglass light leak rate value CL is according to following formula, calculating and obtain:
CL=（YL
LBRW－YL
LBRB）/（YL
LWRB－YL
LBRB）
In the same manner, for respectively this right and left eyes synchronizing signal 220A, 220B, 220C, 220D, 220E, 220F and standard right and left eyes synchronizing signal 220, luminance meter 130 by right eyeglass 124 out of the ordinary measure left eyes white/the black test pattern brightness value YR of right eye
LWRB, a left eye is black/the white test pattern brightness value of right eye YR
LBRWAnd the black test pattern brightness value YR of a deceive/right eye of left eye
LBRB, its left eyeglass light leak rate value CR calculates and obtains according to following formula:
