Abstract

Three-dimensionally picking up, recording and reproducing an image can be executed without changing the television standards, the standards of a computer image and an animated image, and the associated devices by adding a three-dimensionally image projecting part, a device for converting a united-standards communication signal, and a time-division shutter. When picking up a television image, computer image, or animated image 2 and 3, a display section (1) is added to display right and left images in a three-dimensional image. A photodetecting device of the transmitter is additionally provided in the part where the reproduced three-dimensional image is displayed. Communication signals of the united standards are transmitted by the transmitter. A receiver receives the signals and the time-division shutter is operated to right and left in order to form the three-dimensional image of a time-division type which is viewed three-dimensionally due to the binocular parallax. Further, a full-circular image is imaged by an apparatus for picking-up an all-around three-dimensional image which uses linear imaging elements or a conical mirror.

Description

 m Itoda »Display of stereoscopic images · Additional display of signals

 The present invention relates to a method for realizing a time-division stereoscopic image with a television image, a computer image, and a film image. Claims 1 to 7 will be described below.

 Complementary color glasses, polarized glasses, and time-division shutter methods are available to achieve stereoscopic images using glasses with binocular parallax. There are many proposals for time-division shutter methods. · Those that use special equipment for reproduction are technically complete.

 [Problems to be solved by the invention]

 In the case of the time-division shutter stereoscopic video, the force that requires the time-division shutter <The driving signal standards are not standardized, so the time-division shutter has not spread and Not generalized.

 In the case of TV video, each of the conventional technologies requires special equipment for shooting, recording, and playback, and is a separate system, and the standards are not uniform.

 Computer images have great potential and some have been commercialized, but have not become widespread due to the diversification of computer display devices and the problem of standard differences between models.

For film images, silver halide film is superior in resolution and preservation to television and convenience images, but because of the continuous light source, time-division stereoscopic images can be used. When projecting images, a high-speed shutter was required to switch the light source, and stereoscopic video systems with polarized glasses were common. Polarized glasses were inexpensive, but a special screen was required, and polarized glasses were also common. Not a movie. With the decline of movie theaters due to the spread of Levi, only a small number of stereoscopic video works have been produced.

 The present invention makes it possible to use a common time-division shutter in all video systems by using a communication signal unified with the display of stereoscopic video, and the use of conventional video systems to capture, record, and reproduce stereoscopic video becomes widespread. The subject of the invention

 In the case of conventional TV systems such as NTSC, PAL, SECAM, clarification, and hi-vision, and computer-based video, a stereoscopic video display is added to the image, the display is detected, and a unified standard communication signal is transmitted. In the future, when stereoscopic video becomes widespread and stereoscopic video signals are standardized for each video system, the stereoscopic video signal will be detected and transmitted as a unified standard communication signal.

 In the case of film images, a pulsed light source is used as the light source, and a uniform communication signal is transmitted in synchronization with the light emission. It is orthogonal to the V-shape and is opened when the power is turned off. For moving images, for personal use, a stereoscopic video display is added outside the screen range, the display is detected, and sent as a unified standard communication signal fg In commercial use, stereoscopic video display is not necessarily required, and a uniform standard communication signal synchronized with the left and right images is transmitted. In the case of still images, stereoscopic video display is not necessarily required, and pulse emission is also required for moving images. Use of a light source improves image quality.

 In response, it controls the operation of the time-division shutter.

[Action]

 A 3D image is added to the image during the shooting, drawing, and playback processes.

 The stereoscopic video display is displayed on the screen to be reproduced and detected by the light receiving unit of the transmitter attached to the screen. Or, the stereoscopic video display is detected during the image reproduction process.

 Converts the detected 3D image display into a communication signal of the unified standard and sends it.

In the case of commercial film moving images and slide projectors that use a pulsed light source, a uniform communication signal is transmitted from the projector. The signal is received by the receiver and converted into a control signal for the time-division shutter for the left and right images. Playback is performed with the time-division shutter synchronized with the left and right images. BEST MODE FOR CARRYING OUT THE INVENTION

 【Example】

 An example of a television image will be described below with reference to drawings. A computer image and a film image conform to a television image. FIG. 1 shows a stereoscopic image display according to claims 1 and 2 and an aspect ratio of 3: 4. This is the standard for video screens. The broken line is a high-definition video screen with an aspect ratio of 3: 5. When adding a stereoscopic video display with a film video, the stereoscopic video display is outside the lower left corner of the screen area. Figure 2 shows the details of 1-dimensional image display according to claim 2. la display left display section, left and right display section of lb display image, showing left and right of the displayed image, and lc showing left and right of the next image. It consists of four parts: the left display part for the next image and the right display part for the Id next image.

 When the display image is the left image, each display unit displays the left display unit of the la display image in white, and displays the right display unit of the lb display image in black. When the right image, the la display image displays the left display unit. It is displayed in black, and the right side of the lb display image is displayed in white.

When the next image to be displayed is the left image, the left display part of the lc next image is displayed in white, and the right display part of the Id next image is displayed in black. The left side of the lightning image is displayed in black, and the right side of the Id next image is displayed in white. La, lb display image left and right The display is required for the source image taken, and the lc and Id next image left and right sides are displayed. The display image display section is divided into the display image and the next display image. The conversion between the NTSC system and the TV system such as the PAL system and the conversion between interlace and non-interlace are performed between the film and the TV. Because the playback order of the images may be changed by conversion, etc., the left and right display units lc and ld of the next image are made equal to the display image left and right display units la and lb of the next image as appropriate. , Time is required to switch between left and right transmission of the time-division shutter. There is because there may not be the opposite image. The simplest method of adding a 3D image display is to place a light emitter on the 3D image display section of the imaging device or film and stop the light emission in synchronization with the left and right of the image. It is also possible to use visible monochromatic light. Fig. 3 shows a display example of one-dimensional image display. La is black and lb is white, indicating that the display image is the right image, and lc is The white and Id black indicate that the next image is the left image. Figure 4 shows a display example of 1 stereoscopic image display.La is white and lb is 黑. An image indicating that the image is the left image is displayed, and that lc is black and Id is white indicates that the next image is the right image. The four light receiving parts are installed on the left and right signal display parts of the next image after lc and Id of the image. The 4a next image left light receiving element and the 4b next image light receiving element are visible light receiving elements. Malfunctions can be reduced by using multiple light-receiving parts. Change the direction of the light-receiving part in the case of a light-emitting or rear light-emitting screen and in the case of a front light-emitting screen. This is a block diagram of the transmitter.

 The electric signals from the light-receiving elements 4a and 4b pass through 5 detection intensity adjustment circuits, 6 amplification circuits, 7 discrimination circuits, and 8 delay time adjustment circuits, respectively, and communicate with the display colors of the left and right display sections of the lc and Id next images in Table 1. According to the signal logic, according to the communication signal standard described in claim 3, as the infrared modulated wave of 55 kHz when the next image is the left image and 35 kHz when the next image is the right image, it is assumed that the next image is 100 kHz. The adjustment circuits 5 and 6 are used to adjust the brightness of the stereoscopic video display and the time to switch to the next image depending on the video system.

The transfer method is based on infrared rays, but in consideration of simultaneous use of multiple images, it is desirable to provide 10 external output terminals for wireless use of light and radio waves and for wired use of signal lines. In this case, the communication signal standard for stereoscopic images described in claim 2 operates with an input / output impedance of 600 Ω unbalanced 1 V pp. This terminal is used to transmit audio and other signals simultaneously. When carrying audio signals simultaneously, the left side The stereoscopic image communication signal shall be sent to the audio signal side. When projecting the infrared signal of the communication signal on the screen, the material of the screen shall be a material that reflects infrared light. The communication signal shall be added to the left side of the screen indicate.

 [Table 1] Logical table of display colors and communication signals for the left and right display sections of the next image

Fig. 7 shows an example in which in the installation example 1 of the 11 transmitting device described in claim 4, 4 light receiving units of the transmitting device are separated and a stereoscopic video display is displayed on the left side of the 12-screen range. In the installation example 2 of the transmission device 11 described in the item 4, the components from 4 to 10 are integrated and the stereoscopic image display is displayed at the lower left outside the 12-screen range in the example 2. 13 is a block circuit diagram of the receiver. 13 The light-receiving part is an infrared light-receiving element. The electric signal of the light-receiving part is 5 detection intensity adjustment circuit, 6 amplification circuit, 8 delay time adjustment circuit, and 55 kHz of the left image. After passing through the 14 discrimination circuit of 35 kHz of the right image, the left and right 21-time division shutters are opened and closed as long as 110 seconds until the next signal is received. Compensates the switching time of the left and right opening and closing of the time-division shutter. 16 Supply power from the power supply. Sets the polarization axis when using a polarizer that is required with a 11 15 external input terminal for transmission devices of similar wired and transmitting device. 18:00 split shutter V-shaped, the power supply OFF This is sometimes used as a transmissive type. This is used when playing back polarized 3D images.

 [Table 2] Logic table of communication signals and time-division shutter operation

Fig. 10 shows an example of a receiver incorporating the receiver according to claim 6.This is a top view of the simplest configuration of a glasses-type receiver combined with an 18 time-division shutter. 13 The power supply unit uses rechargeable batteries as standard, but it is desirable to consider the use of dry batteries. 16 The replacement lid for the power supply unit should be separated from the main unit. 13 Light-receiving part and 15 External input terminal are iked on the left side. Figure 11 is a front view of the receiver shown in Figure 10. 18 When a polarizing plate is used for a time-division shutter, an arrow is used. The direction of polarization is V-shaped, which is orthogonal to the left and right. Also, the shutter is not tracked and is transparent in the state.-Fig. 12 is a side view of the receiver in Fig. 10 FIG. 13 is a block diagram of a TV stereoscopic video recording and recording system example 1 according to claim 7. Two sets of left and right lights The first field of the two fields that compose one frame of the interlace system using the system and 19 image pickup bodies is assigned to the left, and the second field is assigned to the right. The left image display is a 20 left / right display addition circuit. The la and lb display image left display and the lc and Id next image right display parts are simultaneously added. 19 The right and left display images of la and lb and the left signal of the next image of lc and Id are simultaneously added by the left and right display addition circuit, and the odd field is recorded in the left image and the even field is recorded in the right image by the switching circuit. The vertical resolution is 1 × 2, but the repetition frequency of shutter opening / closing per eye is 3 OHz in the NTSC system, which is based on the number of frames per second of 8 mm film video. When converting to non-interlaced images such as clear vision, a special conversion device is needed to change the order of the left and right images. Figure 14 shows the stereoscopic image obtained by the method of Figure 13 and the stereoscopic image. Figure 15 is a schematic diagram of the image display. Figure 15 shows Example 2 of the stereoscopic image shooting and recording method described in claim 7. The left and right sides are used for each frame by using two sets of left and right optical systems and shooting elements. This method assigns images alternately. Left and right image signals are displayed 19 left and right The la and lb display image left and right signals are added by the adder circuit, respectively, and are switched for each frame by the 20 switching circuit. The lc and ld next image left and right display for each field are changed by the 21st image left and right signal adder circuit to the next image, respectively. Display the same image as the left and right signals of the left image. The odd frame is recorded on the left image, and the even frame is recorded on the right image in order and played back.

 Although the vertical resolution can be maintained, the repetition frequency of shutter opening / closing per eye is 15 Hz in the NTSC system, which is almost equivalent to the number of frames per second of 8 mm film video. Fig. 15 is a schematic diagram of the stereoscopic image obtained by the method of Fig. 15 and the display of the stereoscopic image. Fig. 17 is an example 3 of a TV stereoscopic video recording method according to claim 7. NTSC in non-interlace In this method, left and right images are alternately assigned to each frame at 120 frames per second, and one set of left and right frames is played back twice.

The right and right image signals of the two sets of 19 image pickup bodies are added to the 1a and 1b display image left and right signals by the 20 left and right signal addition circuits, respectively, and are passed through the recording and playback circuit. The conversion circuit switches every field, converts from interlaced to non-interlaced, and reads out twice at double speed sequentially. The left / right display of the next image is displayed in the same way as the left / right display of the next image, and the odd frame is played back in the order of the left image and the even frame is played in the order of the right image. 23 Recording / playback circuit uses double-speed VTR, 2 tracks Uses two conventional VTRs, or two conventional VTRs. Commercial broadcasting is possible if two conventional channels are used for playback. The 24-conversion circuit has two sets of field memories. Four sets of frame memories are required.

 The repetition frequency of shutter opening / closing per eye is 60 Hz at double speed in the NTSC system, which is almost equivalent to the image quality of a 35 mm film image. By changing the number of readings by the 24 conversion circuit, Still images and slow-speed images are also possible. Realized by clear vision standard.

Fig. 20 is the 21st image left and right display addition circuit by the method of Fig. 17 Fig. 3 is a schematic diagram of an image to which a stereoscopic image display is added.

【The invention's effect:】

 By displaying the stereoscopic video display shown in Fig. 1 and Fig. 2 in the image and adding the unified standard transceiver shown in Fig. 3 to Fig. 20, the conventional NTSC, PAL, SECAM, ClearVision, and high vision It is possible to reproduce stereoscopic images with the conventional shooting standards without changing the TV system with different broadcasting standards, such as computer and video standards, computer video and film video standards, and equipment.

According to the signal standard of the unified standard between transmission and reception according to the present invention, it is possible for a single transmitting device to receive multiple receiving devices. According to the present invention, a time-sharing system common to all video systems is used. 3D images using jitters are possible.

 9. The receiving device and the time-division shutter can continue to be used even if the standard of each video system is changed and stereoscopic broadcasting becomes a standard.

[Prior art]

Conventional optical projectors are incandescent bulbs, fluorescent lamps, light-emitting diodes, and continuous emission from discharge tubes. A light source was used. The movie projector used a mechanical shutter synchronized with the film.

[Problems to be solved by the invention]

 Projection of conventional technology film images (including transmissive displays such as transmissive liquid crystal displays), film projectors, slide projectors, overhead projectors (0.H.P.), and stereo projectors In the case of the light source of the device, when the commercial AC power supply was used directly without rectification, the light emission intensity changed according to the frequency of the power supply. However, it was used not for intermittent light emission but for continuous light emission. Therefore, a light source shutter was necessary for use in time-division stereoscopic images, and control was difficult when the light emission interval was short.

 [Means to solve the problem]

 The light source of conventional optical projection equipment is replaced with a pulsed light source such as a discharge arc tube.

[Action]

 The light source of the conventional optical projection device is replaced with a pulsed light source, and a light-emitting power supply and a trigger circuit that can adjust the light-emitting voltage and light-emission duration are added. BEST MODE FOR CARRYING OUT THE INVENTION

 【Example】

 FIG. 27 is a block diagram of an optical projection device using the pulsed light source according to claim 9.

31 Irradiate 31 films with a pulse light source and project 26 images on 12 screens with an optical lens. 33 Adjust brightness (emission voltage adjustment) and brightness (emission duration adjustment) with a light emission power supply circuit. 34 Generate a light emission signal The circuit generates a signal synchronized with the power supply frequency when using a commercial AC power supply. When using another power supply, a synchronization signal of about 60 Hz is generated. 35 The trigger circuit activates the pulse light source in accordance with the light emission signal or the external synchronization signal. 36 The external synchronization input terminal is used for stereoscopic video. 37 The external synchronization switch is used. Switches between the light emission signal of the signal generation circuit and the external synchronization signal of the 36 external synchronization input terminal.

【The invention's effect】

 When a pulsed light source is used, the recognizability is high even on a screen with the same average brightness as in the conventional technology, and when a xenon discharge arc tube is used, color rendering properties closer to sunlight than an incandescent bulb can be obtained. The luminescence method has higher luminous efficiency than incandescent bulbs and generates less heat. When using a commercial AC power supply for the still image projection device, it is desirable to synchronize with the power supply frequency. If it is linked to, the light source shutter is not necessary. Also, if a synchronization signal is input to the 36 external synchronization input terminal and the pulse emission is controlled, it can be easily used on one side of the optical time-division stereoscopic video playback system. Claim 10 is described.

 [Prior art]

 In optical stereoscopic video projection, polarized glasses are common, and there is no time-division stereoscopic projection.

[Problems to be solved by the invention]

For film images, silver halide film is superior in resolution and preservation stability to television and combi- ter images, but since the light source is continuous emission, it projects time-division stereoscopic images. In such cases, a high-speed shutter was required to switch the light source, and polarized glasses-type stereoscopic video systems were generally used. Polarized glasses are inexpensive, but a special screen is required. There are no movies. With the spread of large-screen TVs, the number of movie theaters has decreased, and only a small number of stereoscopic video works have been created. X-ray stereoscopic images have been proposed for a long time, and their effects have not been effectively utilized because the perceived power and playback methods are not common. DISCLOSURE OF THE INVENTION

By combining the projection device of Fig. 27 with the 11 reception device and the 20 transmission device, 38 left and right video exchange switches and 3 9 subordinate 'Single operation switching switch enables independent and interlocked stereoscopic video projection. 20 Receiver is used for subordinate operation and generates left and right synchronization signals.

 1 1 The transmitting device is used for the main operation, and generates the communication signal described in claim 6 by the synchronization signal. When infrared light is used for the communication signal, the screen is irradiated with infrared light.

34 The light emission signal generation circuit is used for main and stand-alone operation. When using a commercial AC power supply, it generates left and right 3D image signals synchronized with the power supply frequency. Generates the light emission signal of the image alternately. In the case of the main operation, it becomes a synchronizing signal of one circuit of 35 triggers through the 8 delay time adjustment circuit. In the case of the single operation, the supply of the light emitting power that is not used is stopped. .

 [Prior art]

 For all-around video shooting, a slit camera system using a silver halide film is generally used. This slot is placed on a one-dimensional image sensor ('linear'-optical section'). All around three-dimensional images can be shot by changing the image. For full-around three-dimensional images, pseudo-around three-dimensional images can be created by combining ordinary two-lens stereoscopic photos.

[Problems to be solved by the invention]

All-round stereoscopic images with the same binocular parallax can be obtained with the slit camera method, but the camera is complex and expensive because of the need for an interlocking mechanism between the lens, slit, and film. If the viewpoint moves with respect to the screen because the entire binocular parallax is not equal in the pseudo-peripheral stereoscopic video, a complete stereoscopic video of the entire circumference cannot be reproduced.

A high-resolution color image can be obtained using a one-dimensional image sensor for each RGB color. The entire device including the recording device Simple and inexpensive. Claims 1 and 2 are described.

 [Prior art]

 All-round video projection using a conical mirror is a well-known technology in principle.

[Problems to be solved by the invention]

 Although it is a well-known technique in principle, it is not widely used because the captured image is distorted, the resolution inside and outside is extremely different, and the resolution near the center is poor. In conventional all-around video shooting, the lens is set upward and the conical mirror is set above it.Therefore, the higher the lens is above the conical mirror (equivalent to the outer leg of the film), the higher the resolution. Poor resolution of low-angle images. This is the opposite of human visual characteristics.

 [Hands to solve the problem S]

 Set the lens to face down, and place a circular mirror underneath.

[—Action]…

 The lower the object is below the conical mirror (introduced to the outside of the film), the lower the resolution of high-angle images is. This is consistent with clearly recognizing low places and distant high things as unclean BJ3. Best mode for carrying out the invention
