  Hereinafter, embodiments of the stereoscopic eyeglass inspection apparatus of the present invention will be described with reference to FIGS.

(Embodiment 1)
First, the operation of the stereoscopic display system will be described with reference to FIGS.

  FIG. 1 is a perspective view showing an overview of the stereoscopic display device 10 and the shutter glasses 200 constituting the stereoscopic display system.

  A stereoscopic display device (for example, a plasma display) 10 includes an LED 11 and a display unit 12. The stereoscopic display device 10 alternately displays a left-eye image (hereinafter abbreviated as “L image”) and a right-eye image (hereinafter abbreviated as “R image”) on the display unit 12. And a synchronization signal (hereinafter abbreviated as “shutter control signal”) indicating the shutter switching timing of the shutter glasses 200 generated based on the V synchronization signal indicating the display start timing of the R image is transmitted to the shutter glasses 200.

  The shutter glasses 200 include a left-eye shutter (hereinafter abbreviated as “left shutter”) 210 a, a right-eye shutter (hereinafter abbreviated as “right shutter”) 210 b, and an infrared light receiving element 221. The shutter glasses 200 receive the shutter control signal transmitted from the LED 11 of the stereoscopic display device 10 by the infrared light receiving element 221, and synchronize with the L image and the R image displayed on the stereoscopic display device 10. Opening and closing of the right shutter 210b (hereinafter, the two shutters of the left shutter 210a and the right shutter 210b are collectively referred to as “shutter 210”) is controlled.

  FIG. 2 is a timing chart showing operations of the stereoscopic display device 10 and the shutter glasses 200 in the stereoscopic display system shown in FIG.

  As shown in FIG. 2, when the stereoscopic display device 10 alternately displays the L image and the R image on the display unit 12, the stereoscopic display device 10 generates a shutter control signal based on the V synchronization signal that is the display start timing of each image. , Output from the LED 11. Thereby, opening / closing control of the left shutter 210a and the right shutter 210b of the shutter glasses 200 is performed.

  For example, when the L image is displayed, the stereoscopic display device 10 outputs a shutter control signal instructing to open the left shutter 210a of the shutter glasses 200 and close the right shutter 210b. Based on the received shutter control signal, the shutter glasses 200 open the left shutter 210a (transmission state) and close the right shutter 210b (blocking state). As a result, when the L image is displayed on the stereoscopic display device 10, the user views the L image only with the left eye.

  Similarly, when the R image is displayed, the stereoscopic display device 10 outputs a shutter control signal instructing to open the right shutter 210b of the shutter glasses 200 and close the left shutter 210a. Based on the received shutter control signal, the shutter glasses 200 open the right shutter 210b (transmission state) and close the left shutter 210a (blocking state). As a result, when the R image is displayed on the stereoscopic display device 10, the user views the R image only with the right eye.

  Thereafter, the left shutter 210a and the right shutter 210b of the shutter glasses 200 are switched in synchronization with the switching timing of the display of the L image and the R image in the same procedure. Thereby, the user can visually recognize the image displayed on the stereoscopic display device 10 through the shutter glasses 200 in a stereoscopic manner.

  Next, an inspection system using the stereoscopic eyeglass inspection apparatus 100 according to the first embodiment will be described with reference to FIGS.

  FIG. 3 is a perspective view showing the stereoscopic eyeglass inspection apparatus 100, and FIG. 4 is a view showing a state in which the shutter eyeglasses 200 are placed on a shutter eyeglass placement table (hereinafter abbreviated as "mounting table") 300. is there.

  As shown in FIG. 3, the stereoscopic eyeglass inspection device 100 includes a transmission unit 140, a detection unit 150, a connection unit 170, an operation unit 180, and a display unit 190. As shown in FIG. 4, the transmission unit 140. The detecting unit 150 is disposed on the mounting table 300.

  6 is a system configuration diagram of an inspection system including the stereoscopic eyeglass inspection apparatus 100 shown in FIG. 3 and the mounting table 300 on which the shutter eyeglasses 200 shown in FIG. 4 are placed.

  Below, each component of an inspection system is demonstrated using FIG.

  The control signal generation unit 111 generates a shutter control signal for controlling the opening / closing of the shutter 210 of the shutter glasses 200 and outputs it to the transmission control unit 130.

  The verification information processing unit 112 creates verification information in which the detection result from the detection unit 150 is associated with the detection time.

  The storage unit 120 stores programs and data necessary for the inspection of the shutter glasses 210.

  The transmission control unit 130 outputs the shutter control signal generated by the control signal generation unit 111 of the signal processing unit 110 to the transmission unit 140.

  The transmission unit 140 outputs a shutter control signal from the transmission control unit 130 from the LED 141. Further, the LEDs 142 and 143 emit light for detecting the open / closed state of the shutter 210.

  The detection unit 150 includes a photodetector (hereinafter abbreviated as “PD”) 221 disposed in the shutter glasses 200 for receiving a shutter control signal output from the LED 141 of the transmission unit 140, an LED 142 of the transmission unit 140, PDs 152 and 153 disposed on the mounting table 300 for receiving light from the light source 143 are provided.

  The wavelength of the LED 141 is assumed to be infrared rays in the range of 700 nm to 1100 nm. The reason is that the wavelength of the LED 141 needs to correspond to the detection wavelength of the PD 221, and the detection center wavelength of the PD 221 is generally in the range of 700 nm to 1100 nm.

  The connection unit 170 includes connection terminals for connecting an external storage device (for example, a USB memory) and connecting to a network on the side surface of the stereoscopic eyeglass inspection device 100. As a result, the USB memory 410 and the network system 420 can be connected to the stereoscopic eyeglass inspection apparatus 100 to output verification information, and the quality of the shutter eyeglasses 200 can be confirmed without limiting the location. The connection unit 170 further includes the switch control line 101 shown in FIG. 3 for outputting an opening / closing signal for directly operating opening / closing of the shutter 210 to the shutter glasses 200 in order to check the battery life of the shutter glasses 200. good.

  The operation unit 180 includes switches 1 to 3 (SW1 to 3) on the upper surface of the stereoscopic eyeglass inspection apparatus 100, and a rotary switch (RSW) to the side surface. SW1 is a test pattern switching switch for switching a pattern in which the opening / closing order of the left and right shutters is defined. SW2 and SW3 are a determination button and a return button, respectively, for determining and canceling test conditions (returning to the previous state). RSW is a test time switching switch for switching the test time in 16 stages. It should be noted that description and illustration of buttons and switches for performing other operations such as power ON / OFF are omitted.

  The display unit 190 includes a liquid crystal panel 191 and three operation check LEDs 192 to 194 disposed on the upper surface of the stereoscopic eyeglass inspection apparatus 100.

  As shown in FIG. 4, the mounting table 300 is configured to place the shutter glasses 200 at a predetermined position by disposing shutter glasses fixing members 320 a to 320 c on the substrate 310. The substrate 310 is provided with LEDs 142 and 143 for emitting light toward the shutter 210 on the front side (front side) of the shutter 210 when the shutter glasses 200 are placed, and the rear side (back side) of the shutter 210. PDs 152 and 153 for detecting light emitted from the LEDs 142 and 143 are arranged. Further, an LED 141 that outputs a shutter control signal to the PD 221 of the shutter glasses 200 is disposed on the front side of the shutter glasses 200 by a predetermined distance.

  FIG. 5 shows a different configuration example of the mounting table 300 shown in FIG. The same components as those in FIG. 4 are given the same numbers. In the mounting table 300 shown in FIG. 5, a sensor car bar is mounted on the LEDs 141, 142, and 143 and the PDs 152 and 153. As described above, by attaching the sensor cover to one or both of the LED and the PD, it is possible to prevent external light from entering the sensor and causing the inspection result to vary or become inaccurate. In particular, the LED 141 that transmits a shutter control signal to the shutter glasses 200 is disposed at a position substantially opposite to the PDs 152 and 153 that detect the open / closed state of the shutter, and thus there is a problem that the control signal is likely to be mixed into the PDs 152 and 153. This sensor cover is effective in preventing this problem. This sensor cover is, for example, as shown in FIG. FIG. 12 shows a cylindrical shape made of resin that can be directly attached to a bullet-type LED or PD, and is effective in limiting the light emission direction and the light receiving range. The example of this sensor cover is only an example, and it is appropriately changed depending on the shape of the LED or PD, and even if it is a thing that stands up between sensors, The effect can be expected.

  Next, details of the inspection of the shutter glasses 200 by the stereoscopic eyeglass inspection apparatus 100 will be described with reference to FIGS.

  FIG. 7 is a transition diagram of the inspection screen in the inspection system of the first embodiment.

  As shown in FIG. 7, when the stereoscopic eyeglass inspection device 100 is activated, a screen A is displayed on the display unit 190.

  When the operator operates SW1 and selects, for example, “3D-MODE 120 Hz” from a plurality of test patterns and determines with SW2, screen A changes to screen B. If the selection of the test pattern is wrong, canceling with SW3 while screen B is displayed can return to screen A.

  Next, when the RSW is operated and, for example, “1” (1 minute) is selected and determined by SW2, the screen B is changed to the screen C.

  By these two selection operations, the test pattern of “3D-MODE 120 Hz” can be set to be inspected for 1 minute. Even when the test time is selected incorrectly, the screen can be returned to the screen B by canceling with the SW3 while the screen C is displayed.

  If there is no problem with the test pattern and the inspection time displayed on the screen C, the test can be started by determining with SW2.

  As the test progresses, the screen display changes from screen D to screen E. When the test is completed, screen F is displayed.

  FIG. 8 is a timing chart showing the relationship between the shutter control signal and the shutter open / close state change in the inspection system of the first embodiment.

  As shown in FIG. 8, the left shutter 210a has an actual open state and time at time t1 with respect to the output of command A (left shutter open) at time T1 and the output of command B (left shutter close) at time T2. The actual closed state is reached at t2. Similarly, the right shutter 210b becomes an actual open state at time t3 and an actual closed state at time t4 in response to a command C (right shutter open) at time T3 and a command D (right shutter close) at time T4. ing. In this case, for example, if the delay (t1-T1) of the time t1 with respect to the time T1 does not conform to the standard value of the response time of the shutter opening / closing of the shutter glasses 200 with respect to the shutter control signal, the shutter glasses 200 to be inspected are NG. Determined.

  In FIG. 8, the test pattern “command A → command B → command C → command D” is used. However, the test pattern performed by the stereoscopic eyeglass inspection apparatus is limited by the number of commands and their order. It is not something. Arbitrary test patterns can be used depending on the purpose of inspection, such as changing the order of commands or adding other prescribed commands.

  In addition, although the open / closed states of the left-eye and right-eye shutters in FIG. 8 are shown as changing in a rectangular manner, the open / closed state of the shutters is normally changed smoothly. The result of binarizing the outputs of PDs 152 and 153 by electrical processing (not shown) such as a comparator may be taken into the signal processing unit 110. Further, the output waveforms of the PDs 152 and 153 may be taken into the signal processing unit 110 via the AD converter, and binarization indicating the open / closed state may be performed inside the signal processing unit 110.

  FIG. 9 shows an example of the data structure of the verification information that is the inspection result.

  As shown in FIG. 9, the verification information includes an ID (for example, a positive integer), a command (for example, command A (left shutter open)) or a shutter open / close state change (for example, state L1 (left shutter from the closed state). Change to the open state))) and the time when the command is output or the time when the shutter open / close state changes. The verification information is saved in an external storage device such as the USB memory 410 as a CSV text file or transmitted to the server via the network.

  10 and 11 are flowcharts showing the verification information acquisition procedure.

  In the example shown in FIGS. 10 and 11, the test pattern “3D-MODE 120 Hz” obtained from the timing chart of FIG. 8 is used.

  First, the flow of processing for performing a plurality of inspections in one operation will be described with reference to FIG.

  When the stereoscopic eyeglass inspection device 100 is activated and the inspection is started, the LEDs 142 and 143 always emit light toward the shutter 210 (step 11, S11).

  In step 12 (S12), it is confirmed that the power of the shutter glasses 200 is ON. For example, a confirmation request may be displayed on the LCD screen 191, or the stereoscopic spectacles inspection device 100 may control the power state of the shutter glasses 200 by the switch control line 101.

  Next, it is determined whether all scheduled inspections have been performed. If there are still inspections to be performed, the control command emission is stopped for a predetermined time, and the operation of the shutter glasses is temporarily stopped. It moves to step 13 (S13) which performs the process which confirms this. This is because, when the shutter glasses 200 have a function of continuing the shutter opening / closing operation before the interruption even when control command reception is interrupted (hereinafter abbreviated as self-running operation), different control commands are continuously transmitted and inspected. If this is done, the operation of the glasses becomes unstable or the command transmission and shutter opening / closing detection described in FIG. At this time, the light emission stop time of the control command needs to be set longer than the self-running operation continuation time of the shutter glasses 200 to be inspected. It is desirable to set it to about twice the duration (the setting method is not described). Thereafter, the process proceeds to step 14 (S14) in which the selected / set inspection is performed.

  After the inspection carried out in step 14 (S14), it is determined again whether or not the scheduled inspection has been executed. If there is still an inspection to be executed, the process proceeds to step 13 (S13) again. If all scheduled inspections have been completed, the process proceeds to step 19 (S19), the LEDs 142 and 143 are turned off, and the inspection is terminated.

  The “scheduled inspection” described in FIG. 10 is to perform a plurality of inspections in one operation. For example, the conditions such as the interval, type, and combination of control commands can be changed variously. Efficient inspection.

  Next, with reference to FIG. 11, a description will be given of the flow of each inspection process among the inspections performed continuously.

  In step 21 (S21), a command A instructing to open the left shutter 210a of the shutter glasses 200 is output from the LED 141 of the transmission unit 140, and ID “1”, the command A, and the time T1 when the command A is output are paired. The recorded data is recorded, and the process proceeds to step 22 (S22).

  In step 22 (S22), it is determined that the PD 152 of the detection unit 150 has entered the state L1 (the left shutter 210a has changed from the closed state to the open state) by detecting the light from the LED 142, and the ID “2” and the state L1 are detected. And the data which made time t1 which became the state L1 into a group is recorded, and it moves to step 23 (S23).

  In step 23 (S23), the command B instructing to close the left shutter 210a of the shutter glasses 200 is output from the LED 141 of the transmission unit 140, and the ID “3”, the command B, and the time T2 at which the command B is output are paired. The recorded data is recorded, and the process proceeds to step 24 (S24).

  In step 24 (S24), it is determined that the PD 152 of the detection unit 150 has stopped detecting the light from the LED 142, so that the state L2 is entered (the left shutter 210a changes from the open state to the closed state). The data which made L2 and the time t2 which became the state L2 a set is recorded, and it moves to step 25 (S25).

  In step 25 (S25), a command C instructing to open the right shutter 210b of the shutter glasses 200 is output from the LED 141 of the transmission unit 140, and ID “5”, the command C, and the time T3 at which the command C is output are paired. The recorded data is recorded, and the process proceeds to step 26 (S26).

  In step 26 (S26), the PD 153 of the detection unit 150 detects the light from the LED 143 to determine that the state R1 has been entered (the right shutter has changed from the closed state to the open state), and the ID “6” and the state R1 are determined. Data including the time t3 when the state R1 is reached is recorded, and the process proceeds to step 27 (S27).

  In step 27 (S27), a command D instructing to close the right shutter 210b of the shutter glasses 200 is output from the LED 141 of the transmission unit 140, and the ID “7”, the command D, and the time T4 at which the command D is output are paired. The recorded data is recorded, and the process proceeds to step 28 (S28).

  In step 28 (S28), it is determined that the PD 153 of the detection unit 150 has stopped detecting the light from the LED 143, so that the state R2 is entered (the right shutter 210b changes from the open state to the closed state). Data is recorded that is a set of R2 and the time t4 when the state R2 is reached. If the predetermined time has not elapsed, the process returns to step 21 (S21) to continue the acquisition of the verification information. If so, the process proceeds to step 29 (S29), and the acquisition of the verification information is terminated.

  The verification of the quality of the shutter glasses 200 using the verification information acquired in this way is performed by checking whether the left and right shutters 210a and 210b are opening and closing according to the specifications for each shutter control command, and for each shutter control command. (T1-T1), (t2-T2), (t3-T3), (t4-T4), which are delays in the response time of the shutter glasses 200, are calculated, and whether these values are within the range of the standard or not. It is done by judging.

  In the flowchart shown in FIG. 11, the end condition is that the inspection time has passed, but the end condition may be that the control command has been transmitted a predetermined number of times. If the result of the determination is “nonconformity” for a predetermined number of times, the end condition can be set.

  The times t1, t2, t3, t4, T1, T2, T3, and T4 described with reference to FIGS. 9 and 11 may be normal absolute times, or inside the stereoscopic eyeglass inspection apparatus 100. The present invention is not limited to the contents of the time definition as long as the interval between the times to be compared can be accurately calculated with the required accuracy. In the first embodiment, a case has been described in which four switches SW1 to SW3 and RSW are mounted on the operation unit 180 in order to operate the stereoscopic eyeglass inspection device 100. However, the stereoscopic eyeglass inspection device has been described. Any means capable of operating 100 can be used. For example, the stereoscopic spectacles inspection device 100 such as a remote controller may be configured to be remotely operated.

  In the first embodiment, the stereoscopic spectacles inspection device 100 includes the liquid crystal panel 191 for displaying information on the selected test pattern and the like, and the LEDs 192 to 194 for confirming the operation of the stereoscopic spectacles inspection device 100. Although the case where the display unit 190 is configured has been described, the present invention is not limited to this as long as it can display information necessary for the inspection. For example, a configuration may be adopted in which a separate display device is connected to the stereoscopic eyeglass inspection device 100.

  Further, the verification information may be stored in an external storage means such as a USB, and verification using the verification information may be performed on a PC or the like different from the stereoscopic eyeglass inspection apparatus. The recording means and the verification program may be provided so that the verification can be performed by the stereoscopic eyeglass inspection apparatus alone.

  In order to confirm that the open / close state of the shutter is maintained for a certain time even if the signal for controlling the opening / closing of the shutter is interrupted, a stop signal indicating that the signal for controlling the opening / closing of the shutter is interrupted is provided as a shutter control signal. May be included in the inspection.

  In the first embodiment, the control command is transmitted from the LED 141. However, not only the control command but also a signal waveform different from the control command is transmitted as “noise”, and “noise” is transmitted. The stability of the shutter opening / closing operation of the shutter glasses 200 when received can also be inspected. In this case, the LED 141 need not be one, and a plurality of LEDs having various center wavelengths may be provided side by side to irradiate “noise” that is closer to the actual use state.

  In the first embodiment, the power control state of the shutter glasses 200 is confirmed once in a series of inspections (step 12 (S12) in FIG. 10). No restrictions. For example, when inspecting the battery life, not only the operation in the case of continuous operation, but also the battery life may be inspected by alternately performing the operation state and the power-off state. The power operation is performed a plurality of times until a stop is detected. Further, in the first embodiment, the description has been given of turning on and off the power by the switch control line 101 in FIG. 3, but the present invention is not limited to this limitation, and the shutter is operated by some mechanical mechanism. The power supply state of the glasses 200 may be controlled.

  By such processing, the operation of the shutter glasses 200 can be inspected with various test patterns.

  In addition, in order to prevent falsification of the verification information, information (for example, a checksum of the verification information) that can detect the falsification of the verification information may be added, or the verification information itself may be encrypted.

  Such processing makes it possible to detect and prevent alteration of the inspection result.
