Abstract
Description
- This invention relates to stereographic display devices and more particularly to such devices as an integral part of an item of apparel such as a pair of glasses or a helmet.
- In current technology for head mounted display (HMD) devices a single display device is used for each eye of the viewer. This is costly because it requires not only a second display device but also additional drive electonics. One solution is to use a single display device and liquid crystal optical shutters to route the images to the appropriate eye. This however is limited by the relatively slow shutter speeds of from about 10 msec to 50 msec which can be further slowed at low temperatures, causing flicker.
- A stereographic display system comprises a signal processing unit receptive of stereo images originating from stereo image sources at a prescribed frame rate. The stereographic display system is operative to generate a multiplexed image stream and a series of synchronization pulses. An image display device is receptive of the multiplexed image stream and operative to display the multiplexed image stream as multiplexed stereo images. A phase-locked loop is receptive of the series of synchronization pulses from the signal processing unit. An optical signal filter system is coupled to the phase-locked loop and receptive of the multiplexed stereo images. The optical signal filter system includes rotating polarization filters that alternately pass or block the passage of a first and second image of the multiplexed stereo images.
- The stereographic display system may be made, in whole or in part, an integral part of an item of apparel such as a pair of glasses or a helmet or headdress.

- In FIG. 1, a stereographic display system is shown generally at100. The
stereographic display system 100 is receptive of stereographic images ordata 122 at a frame rate, ƒr originating from stereographic image ordata sources 120 such as personal computers, video cameras, game consoles, video discs or other stereographic devices which can act as a source of stereographic images or data. A signal or data processing unit, such as avideo processor 124, which includes a synchronization extractor or calculator, receives the stereographic images ordata 122 and generates thereby a set ofoutput signals processor output signal 118R, 118L comprises an electronic signal in the nature of a multiplexed image or data stream. The multiplexed image ordata stream 118R, 118L may be for example left and right images which are directed to an image ordata display device 102 such as a cathode ray tube display (CRT). The image ordata display device 102 provides as output anoptical signal 112R, 112L in the nature of a set of left and right stereographic images or data. The left and rightstereographic images 112R, 112L are directed to a multiplexingoptical filter system 150. The multiplexingoptical filter system 150 comprises a set ofrotatable filters data 112R, 112L. A second videoprocessor output signal 126 comprises a series of synchronization pulses for synchronizing the rotational velocities, ωC, ωR, ωL of the set offilters processor output signal 126 and operative thereby to rotate 138 the set offilters filters motor 136, the rotational velocities, ωC, ωR, ωL, thereof are directly related to the motor rotational velocity, ωM. - FIG. 2 shows a schematic block diagram of the phase-locked
loop 146 of FIG. 1. The phase-lockedloop 146 comprises a digital signal processing (DSP) unit ormicroprocessor 128 receptive of the synchronization pulses of the second videoprocessor output signal 126 and calculates a desired motor rotational velocity, ωM, and motor (or filter) phase, ΦM, for any given frame rate, ƒr. The digital signal processing unit ormicroprocessor 128 provides as output a motorspeed command signal 130. Acontroller 132 is receptive of the motorspeed command signal 130 and provides as output amotor drive signal 134 which is directed to themotor 136. Themotor 136 thereby rotates 138 the set offilters data 112R, 112L from the image ordata display device 102. Themotor 136 includes asensor 142 for sensing the motor rotational velocity, ωM. The sensed motor rotational velocity, ωS, is fed back to thecontroller 132 and to the digital signal processing unit ormicroprocessor 128 as a set ofpulses 140 for synchronization with the synchronization pulses of the second videoprocessor output signal 126. - Reference is now made to FIGS. 3, 4,5, 6, 12 and 13 which should be viewed in conjunction with one another. In FIGS. 3 and 5 the image or
data display device 102 and thefilters data 112R, 112L and also with respect to anaxis 110. Thefilters data 112R, 112L, polarized parallel to the transmission axis 104 a of thefirst filter 104, pass through thefirst filter 104 and further pass through thesecond filter 106 when the transmission axis 106 a of thesecond filter 106 is parallel to the transmission axis 104 a of the first 104. However, the stereographic images ordata 112R, 112L will not pass through thethird filter 108 when the transmission axis 108 a of thethird filter 108 is perpendicular to the transmission axis 104 a of thefirst filter 104. Thus, theviewer 152 perceives the stereographic images ordata 112R in his/her right eye at 114 but does not perceive the stereographic images ordata 112R in his/her left eye at 116. - Conversely, in FIGS. 4 and 6 the image or
data display device 102 and thefilters data 112R, 112L and also with respect to theaxis 110. As such, in FIG. 6, the stereographic images ordata 112R, 112L, polarized parallel to the transmission axis 104 a of thefirst filter 104, pass through thefirst filter 104 and further pass through thethird filter 108 when the transmission axis 108 a of thethird filter 108 is parallel to the transmission axis 104 a of thefirst filter 104. However, the stereographic images ordata 112R, 112L will not pass through thesecond filter 106 when the transmission axis 106 a of thesecond filter 106 is perpendicular to the transmission axis 104 a of thefirst filter 104. Thus, theviewer 152 perceives the stereographic images or data 112L in his/her left eye at 116 but does not perceive the stereographic images or data 112L in his/her right eye at 114. - In FIGS. 5 and 6 it is seen that the
second filter 106 andthird filter 108 rotate either in a clockwise or a counterclockwise direction at an angular velocity of ωR and ωL respectively (e.g., approximately 120π radians per sec or greater.). It is also seen that the transmission axes 106 a, 108 a of the second andthird filters third filters viewer 152 alternately perceives a right stereographic image ordata 112R and left stereographic image or data 112L version of the stereographic images ordata stream 118R and 118L through themultiplexing filters third filters same motor 136. Thefirst filter 104 may be stationary or alternatively may also rotate either clockwise or counterclockwise at ωC. When thefirst filter 104 is rotated, the rotation rates of the second and third filters, ωR and ωL, 106, 108 are adjusted so as to maintain the alternate perception of the stereographic images ordata 112R, 112L by theviewer 152 at the aforesaid frame rates. Thus, when thefirst filter 104 is rotated, ωC=2nωR or 2nωL, where n is an integer. It will thus be understood that FIGS. 5 and 6 represent a “snapshot” of thestereographic display system 100 as the second andthird filters - It will also be understood from FIGS. 3, 4,5, 6, 12 and 13 that the order in which the
filters data 112R, 112L is immaterial. In other words,filters data 112R, 112L prior to the reception thereof by filter 104 (FIGS. 12 and 13). - Referring to FIG. 7, the
stereographic display system 100 is shown connected acommunications network 200, such as a local area network (LAN) or a wide area network (WAN) or the internet. Thecommunications network 200 includes a plurality of stereographic images ordata sources 120 such as personal computers, video cameras, game consoles video discs or other stereographic video devices connected thereto from remote geographical locations by wired or wireless connections, by radio based communications, by telephony based communications, or by other network-based communications. Thestereographic display system 100 may also be connected directly to other likestereographic display systems 100 for displaying the image ordata source 120. Thecommunications network 200 may be similarly connected to other networks and includes network devices configured to execute program software, that allows them to send, receive, store, record and process images either separately or in combination, between and amongst themselves via thenetwork 200. Such processing includes, for example, computer generated holography, image compression and decompression, filtering, contrast enhancement, image sharpening, noise removal and correlation for image classification. - Referring to FIGS. 8, 9,10 and 11, it will be seen that the
stereographic display system 100 of FIG. 1 may be made, in whole or in part, an integral part of an item of apparel such as a pair ofglasses 300 or a helmet orheaddress 400. In FIG. 8 thestereographic display system 100 is mounted on the pair ofglasses 300, viewable therefrom and receptive of the stereographic images ordata 122. In FIG. 9, the motor,sensor combination image display device 102 and the multiplexingoptical filter system 150 are made an integral part of the pair ofglasses 300 and receive the multiplexed image ordata stream 118R, 118L, themotor drive signal 134 and provide the set offeedback pulses 140. In FIG. 10 a helmet orheaddress 400 contains thestereographic display system 100 and is worn by a viewer about the head and viewable therefrom. In FIG. 11, the motor,sensor combination optical filter system 150 are made an integral part of the pair ofglasses 300 and receive the stereographic images ordata 112R, 112L, themotor drive signal 134 and provide the set offeedback pulses 140.
