2. Description of the Related Art Conventionally, a method using parallax between left and right eyes has been proposed.
It is known that a three-dimensional image can be obtained by capturing a still image or a moving image and reproducing it so that the left and right eyes can observe it. When constructing such a stereoscopic image capturing and reproducing system, it is conceivable to reproduce the image on the TV screen.However, when constructing a dedicated system, it is possible to reproduce the image on the liquid crystal display panel and stereoscopically view it. Conceivable. If a liquid crystal display panel is adopted, it can be made compact and a portable system can be constructed.

At present, a liquid crystal display panel widely used for image display is a so-called TFT type, and this TFT type liquid crystal display plate is arranged in a matrix and has R, G, B colors. Three pixels corresponding to each of the three primary colors R, G, and B using a large number of pixels divided into the three primary colors.

A device having a liquid crystal display function of displaying an image on a TFT type liquid crystal plate has a space that can be occupied by the liquid crystal plate, especially when the device is intended to be carried and used. Although it will be limited to small, TF
Since the R, G, and B pixels are arranged on the T-type liquid crystal panel while keeping a distance from each other, the actual number of pixels is 1/3 of the total number of pixels and lacks in definition. And the difficulty of obtaining a fine resolution due to the characteristics of the TFT type liquid crystal panel. The image displayed there is hardly high-definition, and characters with thin lines are hardly legible. It is. Furthermore, the power consumption of the light source for illuminating the TFT type liquid crystal panel is large, and it is not only difficult to use the battery for a long time by driving a battery, but also heat is generated. in this way,
Particularly, in a portable device, the TFT type liquid crystal panel has an advantage of being able to display an image, but has various disadvantages as described above.

SUMMARY OF THE INVENTION In view of the above circumstances, the present invention is directed to an image reproducing apparatus capable of observing an image of good image quality while being small, and an image photographing apparatus capable of photographing an image suitable for image reproduction by the image reproducing apparatus. It is an object of the present invention to provide a device and an image capturing / reproducing device in which the devices are combined.

[0006]

In recent years, instead of a TFT type liquid crystal panel comprising pixels divided into three primary colors of R, G, and B,
The liquid crystal panel itself has no color pigment, and an image is formed using all pixels, and a liquid crystal display unit in which the color of the image is determined by the color of the backlight has entered the practical stage (for example, Kopin C
operation 695 Myles Stan
dish Blvd. Taunton, MA027
80) Trademark SMARTSLIDE etc.).

The present invention was inspired by the appearance of such a liquid crystal display unit.

It is preferable to control so that

According to the characteristics of the human eye, when an image is sequentially updated at a speed of 1/16 sec or more per frame, it is recognized as a moving image. Further, in the image photographing apparatus of the present invention, the recording medium driving unit allows only one recording medium to be loaded at the same time, and the recording medium driving unit controls the image captured by each of the pair of photographing lenses.

On the other hand, two recording media are loaded and the loading is performed. If the left and right images are recorded on each of the two recording media, the respective recording media can be shared with a conventional normal image capturing and reproducing system that is not a stereoscopic image.

According to another aspect of the present invention, there is provided an image reproducing apparatus, comprising: a transmission type liquid crystal plate having a large number of pixels arranged two-dimensionally and forming an image on the large number of pixels as a whole; A liquid crystal display unit having a light source unit that emits light in each of a plurality of emission colors and irradiates the liquid crystal plate from the back, an image signal representing a color image is input, and the color image corresponds to the plurality of emission colors of the light source unit A plurality of decomposed images formed by decomposing are sequentially formed on the liquid crystal plate, and in synchronization with the sequential formation of the decomposed images on the liquid crystal plate, the light source unit is moved to the decomposed images formed on the liquid crystal plate.

In the above-described configuration for distributing the image formed on the liquid crystal plate to the left and right, the interface circuit forms a plurality of separated images forming one frame of a left-eye color image and one frame of a right-eye color image. When a plurality of decomposed images obtained by combining a plurality of decomposed images are combined into one group, the decomposed images on the liquid crystal plate are updated at a speed of 1/16 (sec / group) or more, and the liquid crystal plate is updated. In synchronization with the sequential formation of the separated images, the light source unit may be made to blink so as to emit pulsed light having a light emission time shorter than the time during which one separated image is formed on the liquid crystal plate. preferable.

As described above, according to the characteristics of the human eye, it is known that if image information is sequentially updated at a speed of 1/16 sec or more per frame, it is recognized as a moving image. In the case of, the image (color image) of one frame on each of the left and right sides is further decomposed into a plurality of decomposed images, so it is necessary to update the image at a higher speed.

The decoration data memory 224 stores image information for decorating an image, for example, image information such as various characters and various designs (templates), and stores characters and templates from the decoration data memory 103. Read out as an electric image signal,
2 to the image processing circuit 223.

The key input button 207 shown in FIG.
Is a button for inputting various commands and data to the image reproducing apparatus by operating buttons. The key input button 207 is provided via the I / O port 225 for mediating various data input from the outside. Controller 22
2 are connected. The operation of the key input button 207 determines where the image information is input. A character message or the like to be superimposed on an image can be input from the key input button 207. When a character message is input from the key input button 207, a signal representing the character message is also sent to the image processing circuit 223. It is input and synthesized as part of the image. Here, the signal representing the character message is also included in the image signal without being distinguished from other image signals.

The external connection terminal 205 is a terminal for connecting to, for example, a personal computer or the like, and can input various commands and images from the personal computer side. The external connection terminal 205 is also connected to the I / O port 22.
5 is connected to the system controller 222. The image signal that has been synthesized and edited as necessary in the image processing circuit 223 is provided as a single path by D
Is converted into an analog image signal by a / A converter 226,
It is output to the outside via the buffer amplifier 227 and the video output terminal 206 also shown in FIG. The video output terminal 206 is connected to, for example, a video terminal of a television, and can display an image on the television. However, at this time, only one image signal for the right eye or the left eye is output.

As another path of the image signal output from the image processing circuit 223, an image is formed on the liquid crystal plate 2101 (see FIGS. 11 to 14) of the liquid crystal display unit 210 via the interface circuit 228. There is a path unique to the present invention that provides a stereoscopic image to an observer looking through the eyepiece window. At this time, in synchronization with the image formation on the liquid crystal plate 2101, at the timing when the image for the left eye is formed, the liquid crystal shutter 216 for the left eye is used.
b is opened, the liquid crystal shutter 216a for the right eye is controlled to be closed, and at the timing when the image for the right eye is formed on the liquid crystal plate, the liquid crystal shutter 216a for the right eye is opened and the liquid crystal shutter 216 for the left eye is closed. Controlled. Details will be described later.

An image attitude correction circuit 230 is shown between the image processing circuit 223 and the interface circuit 228. The image posture correction circuit 230 is provided with the image processing circuit 2
It has a function of converting the image signal sent from the H.23 into an image signal representing an image converted into a left-right, up-down inverted image.
However, this image posture correction circuit 230 is shown with reference to FIG. 9 for an embodiment described later, and in the first embodiment shown in FIGS. 7 and 8, a normal image is formed on the liquid crystal plate. When this is done, the normal image is directly observed by the observer's eyes. Therefore, in the case of the first embodiment shown in FIGS. 7 and 8, this image posture correction circuit is unnecessary.

FIG. 10 is a circuit block diagram showing the internal configuration of the interface circuit 228. The interface circuit 228 includes an operating frequency conversion circuit 2281, a display control circuit 2282, and a D / A converter 2283. Details will be described later.

FIGS. 11 and 12 are a sectional view and an exploded perspective view, respectively, showing an example of the configuration of a liquid crystal display unit. However, the housing is not shown in FIG. The liquid crystal display unit 210 includes a transmission type matrix driving type liquid crystal plate 2101 and a diffusion plate 210
2. A light-intensifying plate 2103 is provided, and LEDs 21041, 21042, and 210 for emitting red (R), green (G), and blue (B) light on the back side.
There is provided a circuit board 2104 to which 43 is attached. These are disposed inside a housing 2105, and a transparent protective cover 2106 is fixed to the housing 2105 at a position in front of the liquid crystal plate 2101.

A large number of pixels (for example, 240 pixels vertically × 320 pixels horizontally = 76,800 pixels in total) are two-dimensionally arranged on the liquid crystal plate 2101.
1 itself does not have the R, G, and B elements. At one time, one image is formed using all the pixels constituting the liquid crystal panel 2101, and the R, G, and B elements arranged behind the liquid crystal panel 2101 are formed.
G, B three LEDs 21041, 1042, 210
Depending on which of the 43 LEDs is lit,
The light passes through the liquid crystal plate 2101 and further passes through the protective cover 210.
The light transmitted through 6 becomes an image of that color.

FIGS. 13 and 14 are a sectional view and an exploded perspective view excluding the housing, respectively, showing another example of the structure of the liquid crystal display unit. A liquid crystal plate 2101 of the same type as the liquid crystal plate shown in the liquid crystal display unit shown in FIGS. 11 and 12 and a liquid crystal panel behind the liquid crystal plate 2101 are provided inside a housing 2105 having a transparent protective cover 2106 fixed to the front surface. A plate 2107 and a circuit board 2104 on which three R, G, and B LEDs 21041, 1042, and 21043 are mounted are provided. However, the LEDs 21041, 1042, 2 on the circuit board 2104
The mounting position of the LED 1043 is different from the mounting position of the LED on the circuit board constituting the liquid crystal display unit shown in FIGS.
It is attached to a position close to the upper edge in a direction to illuminate the diffusion plate 2107.

Three LEDs 21041, 1042, and 2
When any of the light sources 1043 is turned on, the emitted light once enters the diffusion plate 2107, is uniformly diffused in the diffusion plate 2107, and irradiates the liquid crystal plate 2101 from the back. FIG.
The liquid crystal display unit 210 shown by one block in FIG. 9 may have the configuration shown in FIGS.

FIG. 15 shows the liquid crystal display unit 21.
9 is a timing chart showing an example of a sequence for forming an image on the liquid crystal plate 2101 constituting the pixel No. 0. FIG.
15A shows the timing of image formation on the liquid crystal plate 2101. FIGS. 15B and 15C show the liquid crystal shutter 216b for the left eye and the liquid crystal shutter 216 for the right eye, respectively.
3 shows the opening / closing timing of “a”. The liquid crystal plate 2101
An image is formed on the interface circuit 2 shown in FIG.
Ten display control circuits 2102 play the role, and the system controller 222 shown in FIG. 9 plays the role of opening and closing the liquid crystal shutters 216a and 216b.

Here, the color images for the left eye and the right eye are decomposed into frame images corresponding to the respective colors of R, G, and B. As shown in FIG.
In time division, first, a frame image corresponding to R for the left eye is formed, then a frame image corresponding to G for the left eye is formed, and then a frame image corresponding to B for the left eye is formed. Moves to the right eye, a frame image corresponding to R for the right eye is formed, a frame image corresponding to G for the right eye is formed, a frame image corresponding to B for the right eye is formed, and further a frame image corresponding to B for the left eye is formed. Then, a frame image corresponding to R for the left eye is formed, and so on, and R, G, and B frame images are alternately formed for the left eye and for the right eye, and cyclically formed.

Although not shown in FIG. 15, in synchronization with the formation of each frame image on the liquid crystal plate, a frame image corresponding to R is formed regardless of whether it is for the left eye or the right eye. The LED 21041 of R lights up with a pulse at the timing of the operation, the LED 2102 of G lights up at a timing at which a frame image corresponding to G is formed, and the LE of B lights at the timing at which a frame image corresponding to B is formed.
D21043 is pulsed. Then, light of the colors R, G, B, R, G,... Carrying image information is sequentially emitted from the liquid crystal display unit 210 in a time sharing manner.

On the other hand, the liquid crystal shutter 216b for the left eye and the liquid crystal shutter 216a for the right eye are shown in FIG.
As shown in (C), at the timing when the frame image for the left eye is formed on the liquid crystal plate 2101, regardless of the color of the frame image corresponding to R, G, or B, the liquid crystal shutter for the left eye is used. The liquid crystal shutter 216b is controlled to an open state (a state in which light passes through the liquid crystal shutter), and the liquid crystal shutter 216a for the right eye is controlled to a closed state (a state in which the liquid crystal shutter blocks light). At the timing when the right-eye frame image is formed, the liquid crystal shutter 216a for the right eye is controlled to be open and the liquid crystal shutter 216b for the left eye is controlled to be closed.

As a result, the R, G, and B images are sequentially incident on the right eye and the left eye alternately and with respect to each of the right eye and the left eye. Is formed, and the image that enters the left eye and the image that enters the right eye are independent. By preparing images that differ by the parallax between the left eye and the right eye, the observer can obtain a stereoscopic color image. The image will be recognized.

Here, three R, G, and B frame images forming one frame of a left-eye color image, and three R, G, and B frames forming a right eye color image of one frame. When a total of six frame images including the frame images are grouped into one group, a period T (see FIG. 15) in which the six frame images constituting the group are formed on the liquid crystal plate 2101 is 1/16 sec or less. Is set to This is because if the period T is longer than this, intermittent light and intermittent changes in the image are recognized by the human eye and flicker is recognized, and in the case of a moving image, smooth movement of the image is hindered.

The R, G, and B LEDs 21041,
The pulse width of the light emission pulse of 21042, 21043 is:
The pulse width is shorter than the time t during which the R, G, and B frame images are formed on the liquid crystal plate 31.
It is preferable to emit light with a shorter pulse width within an allowable range in consideration of the brightness of an image reaching the human eye. By doing so, power consumption can be reduced, which is more suitable for an image reproducing apparatus driven by incorporating a battery.

FIG. 16 shows the liquid crystal display unit 21.
11 is a timing chart showing another example of a sequence for forming an image on the liquid crystal plate 2101 constituting the pixel 0.
As in the case of FIG. 15, FIG. 16A shows the timing of image formation on the liquid crystal plate 2101, and FIGS. 16B and 16C show opening and closing of the liquid crystal shutter 216b for the left eye and the liquid crystal shutter 216a for the right eye, respectively. It shows the timing.

Here, an R frame image for the right eye is formed following a frame image corresponding to the R for the left eye, and
The G-compatible frame image for the left eye, the G-compatible frame image for the right eye, the B-compatible frame image for the left eye, and the B-compatible frame image for the right eye are formed on the liquid crystal plate 2101 in this order. The liquid crystal shutters 216a and 216b also open and close alternately in synchronization with the formation of one frame image.

Images are formed on the liquid crystal plate 2101 in the order shown in FIG. 16A, and the liquid crystal shutter is opened and closed as shown in FIGS. Good. Although the above description has been made with a moving image in mind, the same applies to the case of forming a still image. In the case of a still image, for each of the left eye and the right eye, only one frame of color image exists, so to speak.
The color image for the frame is decomposed into three frame images corresponding to the respective colors of R, G, and B, and a total of 6
One frame image is cyclically formed on the liquid crystal plate 2101. In this way, a stereoscopic still color image can be provided to the observer.

Here, R, G, B, R, G,...
, The frame image is formed and the LED is turned on and off. However, it is needless to say that R, G, and B need not be arranged in this order, but may be arranged in any order. FIG.
FIG. 11 is a schematic block diagram of an operating frequency conversion circuit 2281 included in the interface circuit 228 shown in FIG.

Here, two frame memories 2281
, 122812, a control unit 22813, and four switch circuits 22814, 22815, 22816, 2281
7 are provided. An image processing circuit 223 shown in FIG. 9 outputs a digital image signal SG representing a color image.
NL1 is transmitted to the interface circuit 228 in synchronization with the clock CLK1 of the first operating frequency, and is input to the operating frequency conversion circuit 2281 shown in FIG. The image signal SGNL1 is basically synchronized with the clock CLK1, and basically, the image signal of a certain frame is stored in the frame memory 2
281, the next frame is stored by frame memory 22812, the next frame is stored in frame memory 22811, and so on.
Two frame memories 22811, 22 for each frame
812 are stored alternately. The control unit 22813 monitors the clock CLK1 and controls the image signal SG for one frame.
Each time NL1 finishes storing in one frame memory, it switches two switches 22814 and 22815 in conjunction.

On the other hand, these frame memories 2281
The same applies to the reading side of the image signal from the image processing device 12282. When the image signal for one frame is read from one of the frame memories in synchronization with the clock CLK2 of the second operating frequency, the signal on the output side is read out. Two switches 2281
6, 22817, and the image signal is read out from the other frame memory in synchronization with the clock CLK2. The switches 22816 and 22817 are switched by the control unit 2 that monitors the clock CLK2.
2813.

Here, the image signal read out in synchronization with the clock CLK2 is referred to as an image signal SGNL2.
When the frequencies of the two clocks CLK1 and CLK2 are equal, for example, the image signal S is already stored in the frame memory 22811.
GNL1 is stored in the frame memory 22812
In the situation where the image signal SGNL1 of the next frame is stored in the frame memory 22812, the image signal SGNL2 is read from the frame memory 22811 while the image signal is stored in the frame memory 22812, and the image signal SGNL1 is stored in the frame memory 22812. At the end, reading of the image signal SGNL2 from the frame memory 22812 may be started at the timing when the image signal SGNL1 of the next frame starts to be stored in the frame memory 22811. However, when the frequencies of the two clocks CLK1 and CLK2 are different, the above-described operation is performed. It cannot operate at such a 1: 1 timing. In this case, the image signal SGNL1 synchronized with the clock CLK1 is converted into the image signal SGNL2 synchronized with the clock CLK2 by storing and reading the image signal as follows.

When the frequency of the clock CLK1 on the input side is high, the two frame memories 22811 and 22812
, The image signal SGNL1 is stored one frame at a time, and even when the timing at which the image signal SGNL1 of the next frame is sent is reached, none of the two frame memories 22811 and 22812 has been completely read out. Can occur. The control unit 22813 monitors both the clock CLK1 and the clock CLK2, and can know that such a state has been reached. Here, two switches 22814, 22 on the input side
Reference numeral 815 denotes two frame memories 22811 and 281
The control unit 22813 switches the input side switches 22814 and 22815 to the neutral point when the above state is reached.
Until one of the two frame memories 22811 and 22812 becomes empty upon completion of reading, the image signal SGNL1 on the input side is not stored in any of the frame memories 22811 and 22812 in frame units.
When one of the two frame memories 22811 and 22812 becomes empty, switches 22814 and 22815 are switched to the empty frame memory, and the empty frame memory is transferred from the beginning of the next frame to the empty frame memory. Start storing.

On the other hand, when the frequency of the clock CLK2 on the reading side is higher than the frequency of the clock CLK1 on the input side, the reading from one of the two frame memories 22811 and 22812 is completed. Image signal SGNL1 to one frame memory
May not be stored yet. The occurrence of this situation is detected by the control unit 22813 monitoring both the clocks CLK1 and CLK2, and when this situation occurs, the control unit 22813 switches the switch 2281
6,22817 is not switched. That is, on the reading side, the image signal of the same frame is read again from the same frame memory. If the storage of the image signal SGNL1 of the next frame in the other frame memory has been completed at the time when the image signal of the same frame has been read out again from the same frame memory, the switches 22816 and 22817 are switched. The image signal of the new frame is read.

The interface circuit 228 shown in FIG.
The operating frequency converting circuit 2281 converts the operating frequency from the frequency of CLK1 to the frequency of CLK2 as described above. The image signal SG whose operating frequency has been converted by the operating frequency conversion circuit 2281 as described above.
NL2 is input to the display control circuit 2282 shown in the interface circuit 228 of FIG. Display control circuit 228
Reference numeral 2 decomposes each frame of the color image into three frames of three primary colors of R, G, and B for each of the right and left frames, and sequentially outputs the frames.

An image signal representing a frame for each color sequentially output from the display control circuit 2282 is a D / A converter 2
At 283, the image signal is converted into an analog image signal and is converted into a liquid crystal plate 2101 (FIGS.
Reference). In addition, the display control circuit 2282 outputs each LED 210 of the liquid crystal display unit 210.
LED 210 toward 41, 210, 4210
A control signal for controlling the blinking of 41, 41, 421, and 21043 is also sent. The operation of the liquid crystal display unit 210 when the image signal and the control signal are input is as described with reference to FIG. 15 or FIG.

The image reproducing apparatus 200 shown in FIGS.
The recording medium 10 loaded in A may be a recording medium on which an image obtained by photographing using the image photographing apparatus 100A described with reference to FIGS. 1 to 4 is recorded, but is not limited thereto. Instead, use a stereoscopic image capturing device that projects images using parallax on the left and right on a normal silver halide type photo film, or perform shooting using two normal cameras side by side. The image formed on the photograph may be read by a scanner or the like, and the image information may be stored in a recording medium, and the recording medium on which the image information is recorded may be loaded to reproduce a stereoscopic image.

Further, one of the two recording media on which an image is recorded by photographing using the image photographing apparatus 100B of the type in which two recording media are loaded, as shown in FIGS.
The image may be loaded in the image playback device 200A shown in FIGS. However, at this time, the stereoscopic image is not reproduced, and the image reproducing devices shown in FIGS. 7 to 9 are controlled so that the same image is provided to the right and left eyes. This is a monocular that performs photographing using another image recording device, for example, a monocular video photographing device or a still photographing device, and records the image on a recording medium, or mounts a silver halide film and performs photographing. The same applies to the case where a photograph is taken on a silver halide film using a conventional camera, and the photograph is read and an image is recorded on a recording medium. The recording medium on which the image is recorded in such a manner is shown in FIGS. When the image is generated by being loaded into the image reproducing apparatus shown in (1), the same image is provided to the left and right eyes instead of the stereoscopic image.

Note that these points are the same in various embodiments described below. FIG. 18 is a schematic diagram showing a main internal structure of the second embodiment of the image reproducing apparatus of the present invention. The image reproducing apparatus 200B shown in FIG.
The difference from the first embodiment shown in FIGS.
Instead of being provided with a belt 202 for wearing on the head, the embodiment shown in FIG. 18 includes a wearing device 2 for wearing over the ear like eyeglasses.
31 are provided.

As shown in the second embodiment, the image reproducing apparatus of the present invention can be made small and light enough to be worn over the ear. FIG. 19 is a schematic diagram showing a main internal structure of a third embodiment of the image reproducing apparatus of the present invention.
FIG. 20 is a sectional view taken along the arrow AA shown in FIG. FIG.
Next, differences from the first embodiment shown in FIGS.

Here, the magnifying lens 2 shown in FIGS.
Instead of 11, a pair of left and right Galileo type magnifying lenses 232a and 232b having the same performance are arranged. By adopting the Galileo type magnifying lenses 232a and 232b, the degree of freedom of arrangement and design is wider than that of the magnifying glass type magnifying lens 211 shown in FIGS. 7 to 9, and a larger magnifying power can be provided. Also, since the Galileo type magnifying lenses 232a and 232b can obtain a normal image, the third embodiment also
The image posture correction circuit 230 shown in FIG. 9 is unnecessary.

In addition, in the image reproducing apparatus 200C shown in FIGS. 19 and 20, the image reproducing apparatus 200 shown in FIGS.
Although the arrangement position and the like of the circuit blocks 220 are different from those of 00A, the Galileo type magnifying lenses 232a and 232b
This is a change in layout due to the adoption of, and there is no essential difference. FIG. 21 shows a fourth embodiment of the image reproducing apparatus according to the present invention.
FIG. 22 is a schematic diagram showing a main internal structure of the embodiment, and FIG.
It is sectional drawing which follows the arrow AA shown in FIG. FIG. 19, FIG.
The differences from the third embodiment shown in FIG.

Here, the Galileo type magnifying lenses 232a, 232 in the third embodiment shown in FIGS.
Instead of 32b, a pair of Kepler-type magnifying lenses 2
33a and 233b are arranged. When a Kepler-type magnifying lens is used, the degree of freedom in arrangement and design is further increased, and the size can be reduced to obtain the same magnification as compared with a case where a Galileo-type magnifying lens is used.

However, if a Kepler-type magnifying lens is adopted, an inverted image is formed. Therefore, an image posture correction circuit 230 shown in FIG. 9 is provided, and a liquid crystal plate 2101 (see FIGS. 11 to 14).
An image is formed on the top, left, right and upside down. This provides a normal image to the observer. Even when a Kepler-type magnifying lens is provided, a normal image may be provided to an observer by devising an optical system without providing an image posture correction circuit.

FIG. 23 is a schematic diagram showing a main internal structure of a fifth embodiment of the image reproducing apparatus of the present invention, and FIG.
It is sectional drawing in alignment with arrow AA shown in FIG. FIG. 25
FIG. 25 is a block diagram showing a circuit configuration of the image reproducing device shown in FIGS. 23 and 24. The differences from the first embodiment shown in FIGS. 7 to 9 will be described. The image reproducing apparatus 100A shown in FIGS. 7 to 9 includes only one liquid crystal display unit 210, and the one liquid crystal display unit 2
10, both right-eye and left-eye frame images are sequentially formed, and the two liquid crystal shutters 216a and 216b distribute the images to the right and left eyes in a time-division manner.
The image reproducing apparatus 200E shown in FIG. 5 includes two liquid crystal display units, a liquid crystal display unit 210a for the right eye and a liquid crystal display unit 210b for the left eye.

Each liquid crystal display unit 210a, 2
10b is the same as the liquid crystal display unit 210 in the first embodiment shown in FIGS. 7 to 9 (see FIGS. 11 to 14). In addition, FIGS.
5 is provided with two liquid crystal display units, and is provided with two magnifying lenses, a magnifying lens 211a and a magnifying lens 211b, and the image reproducing device 200E shown in FIGS. Reproduction device 200A
Half mirror 212, reflection mirror 21 provided in
3, 214 and 215 are unnecessary and have been removed. Further, two liquid crystal shutters 216a and 216b provided in the image reproducing device 200A shown in FIGS.
Have also been removed because they are no longer needed.

On the other hand, the image reproducing device 200E shown in FIGS.
230b are provided, and an audio output circuit 229 is provided as shown in FIG. That is, in the image reproducing device 200E, an audio signal is also handled. Accordingly, for example, the recording medium 10 is allowed to record audio information together with image information, and an audio signal is input from the external output terminal 205 together with the image signal.

An audio signal obtained by reading audio information from the recording medium 10 or an audio signal input from, for example, a personal computer (not shown) via the external connection terminal 205 is sent to the audio output circuit 229 and is output to the D terminal. The audio signal is converted into an analog audio signal by the / A conversion and is distributed to the left and right speakers, and stereo sound is output from the left and right speakers 230a and 230b.

Although the circuit block diagram shown in FIG. 25 shows the image posture correction circuit 230, FIGS.
In the image reproducing apparatus 200E shown in FIG. 4, since the images formed on the liquid crystal display units 210a and 210b are observed as normal images as they are, the image posture correction circuit 230 is unnecessary in this embodiment, and is necessary in an embodiment described later. Becomes

FIG. 26 is a timing chart showing the timing of image formation on each liquid crystal plate provided in each of the two liquid crystal display units 210a and 210b. FIG. 9A shows the timing of image formation on the liquid crystal plate of the liquid crystal display unit for the left eye and FIG. 9B shows the timing of image formation on the liquid crystal plate of the right eye. The left and right color images are read out from the recording medium 10 and decomposed into three frame images of R, G, and B, respectively, and the R corresponding frame image, the G corresponding frame image, and the B corresponding frame are simultaneously displayed on the left and right liquid crystal plates. The images are sequentially formed in the order of the images, and the respective LEDs constituting the left and right liquid crystal display units are sequentially pulse-lit in the order of R, G, and B in synchronization with the formation of the frame image on the liquid crystal plate.

Here, when three frame images of R, G, and B constituting one frame of a left-eye or right-eye color image are grouped into one group, three R, G, and B frames constituting one group are formed. The cycle T (see FIG. 26) in which one frame image is formed on the liquid crystal plate is set to 1/16 sec or less. That is, as can be understood from comparison with FIG. 15, it is sufficient to update the image at half the image update speed in a configuration in which only one liquid crystal display unit is provided and the display is divided into right and left, and the operating speed of the circuit is reduced by that amount to reduce cost. Alternatively, the operation speed of the circuit may be the same, and a moving image having a smoother motion may be formed.

The pulse width of the light emission pulse of each of the R, G, and B LEDs is shorter than the time t during which the R, G, and B frame images are formed on the liquid crystal plate. A shorter pulse width is set within an allowable range in consideration of the brightness of the image, and power consumption is reduced. Although the description of FIG. 26 is made with the moving image in mind, the same applies to the case of forming a still image. The color images of left and right one frame each for left and right eyes are R, G, and B, respectively. Are decomposed into three frame images corresponding to the respective colors, and these three frame images are cyclically displayed on the left and right liquid crystal plates, respectively. This provides a stereoscopic still color image.

FIG. 27 is a schematic diagram showing the main internal configuration of a sixth embodiment of the image reproducing apparatus of the present invention. This FIG.
The image forming apparatus 200F shown in FIG. 23 is different from the image forming apparatus 200E shown in FIGS.
In place of 02, a wearing tool 231 is provided for wearing around the ear like glasses.

As shown in FIG. 27, the type having two liquid crystal display units can be reduced in size and weight so that it can be worn over the ear.
FIG. 28 is a schematic diagram showing a main internal structure of an image reproducing apparatus according to a seventh embodiment of the present invention, and FIG. 29 is an arrow A shown in FIG.
It is sectional drawing which follows -A. The differences from the fifth embodiment shown in FIGS. 23 and 24 will be described.

Here, a magnifying glass type magnifying lens 211 in the image forming apparatus 200E shown in FIGS.
Instead of a and 211b, a pair of left and right Galileo type magnifying lenses 232a and 232b having the same performance are arranged. As described above, the adoption of the Galileo type magnifying lens increases the degree of freedom in arrangement and design, and can also provide a larger magnifying power.
