Description

Description: TECHNICAL FIELD The present invention relates to an apparatus for continuously displaying an image composed of a plurality of pixels as a moving image, and particularly, an image obtained by dividing and reducing a thin line into pixels of a plurality of frames, The present invention relates to an image display device configured to sequentially reproduce and display.

[Technical background of the invention]

Prior to the invention of the present invention, the applicant proposed “a thin line segmenting type continuous photography device” and has already acquired the right (Japanese Patent Application No. 5).
3-155017, Japanese Patent No. 1359318). This device decomposes a continuous photographic image of multiple frames into parallel thin line pixels, reduces each pixel only in the width direction of the thin lines, and then aligns and combines each pixel order to create a single screen. A device characterized by being configured, and in order to visually recognize the screen obtained in this way as a moving image, a cylindrical lens group is arranged in parallel with the pixel, and each of the pixels is arranged through this cylindrical lens group. By selectively observing only specific ones of them, it becomes possible to visually recognize as a specific image, and by displacing this cylindrical lens group and the screen relatively, the selectively visible screen is changed. Therefore, it can be recognized as a moving image.

[Problems to be Solved by the Invention]

When visually recognizing a screen created using the above-mentioned device, if it is a small-scale device that is used for personal use, the image or the cylindrical lens group may be operated upon acquisition. For example, when the device is configured as a large-sized device for displaying to many people, a special mechanism for moving the image and the cylindrical lens group relatively is required.

Here, an image such as a motion-resolved photograph of five frames shown in FIG.
17) and recorded as a single composite image on a video carrier such as a film, the result is as shown in FIG. FIG. 10 and FIG. 11 show a case where the visual recognition cylindrical lens group 2 is arranged in front of the image carrier 1 in which the pixel groups of 4 frames thus constituted are arranged. 2 is this image carrier 1
Is a cylindrical lens group arranged in parallel with each other, and is integrally configured by connecting the cylindrical lenses 2a, 2b, 2c, 2d ... The image on the image carrier 1 is divided corresponding to each of the cylindrical lenses 2a, 2b ... And the divided pixel group sections (hereinafter simply referred to as “sections”).
Are referred to as A), B, C, D ... In the configuration shown in the figure, for example, for section A, pixels A1, A2, A
Four pixels A3 and A4 are arranged, and similarly, four pixels are arranged in each section. Thereafter, the number of pixels arranged in each section indicates the number of frames. That is, in the configuration shown in the figure, four pixels are arranged in each section, so that it is a composite image of four frames.

The observer selectively visually recognizes the pixel group of the specific frame in each section based on the relative positional relationship between each cylindrical lens and the image carrier. For example, pixels A3, B3, C3, D3
The image of the third frame can be observed by selectively recognizing ... And the pixel groups A4 and B4, which are different pixel groups, due to the relative displacement between the image carrier 1 and the cylindrical lens group 2.
The image of the fourth frame is visually recognized by changing such that CC4, D4 ... In this way, the images on the image carrier can be recognized as a moving image by visually sequentially observing the images.

In the above configuration, when each section is a composite video image of 4 frames as shown, the reduction ratio of each pixel is 1/4,
Since the pixel width W is W = P / 4 (P is the cylindrical lens pitch), the relative movement distance between the cylindrical lens group 2 and the image carrier 1 is set by moving the movement distance p three times to perform step feed. You can see the entire image. That is, all the images arranged as pixels on the image carrier can be viewed while the pixels of each section are formed as an integral image by the step feed. Here, since each section is composed of four pixels, four types of images can be visually recognized by moving the cylindrical lens group. Because p
Is P / 4, which is a distance corresponding to the width of each pixel.

FIG. 13 shows an example of an apparatus configured to visually recognize the image by moving the image carrier.

Reference numeral 3 in the drawing denotes a frame body for supporting and fixing the image carrier 1.
Is a guide block 5a attached to the side of the frame 3
Reference numerals 5b and 5b denote guide posts in which the guide blocks are vertically inserted. Reference numeral 6 is a tension spring arranged between the frame body 3 and the base 9, and acts to press the cam follower 7 protruding from the frame body 3 against the cam 8.

In the structure described above, when the cam 8 is rotated leftward at a constant speed as shown by the arrow in FIG. 14 (A), the cam follower 7 causes the radii R1, R2, R of the cam 8 to rise.
The cam follower 7 once stops in a state where it reaches a flat portion (dwell of the cam) having R3 and R4, and drives the image carrier stepwise. First, assuming that the initial position of the cam follower 7 is at the dwell with the minimum radius R1, then the rotation of the cam 8 gradually pushes the cam follower 7 up gradually, and finally reaches the position of the maximum radius R4. To the position of the minimum radius R1 all at once. By moving the image carrier 1 up and down while forming a continuous image with the cam follower 7, it is possible to sequentially view images of specific frames by combining the pixels of the image carrier 1 through the cylindrical lens group. FIG. 14 (B) shows the movement of the position of the image carrier 1 with time.

Although a moving image can be displayed with the configuration described above, there are the following problems.

First, when image carriers having different numbers of frames are attached to the frame body 3, it is necessary to replace the cam with another cam having the number of steps corresponding to the number of frames. In other words, it is necessary to change to a dedicated cam every time you change to a video carrier with a different number of frames, which makes the work considerably troublesome. Next, depending on the pixel configuration accommodated in the image carrier, there are some that can be expressed as a more complicated moving image by appropriately combining the ascending and descending of the image carrier, but even in this case, there is a problem with the above configuration.

As an example, FIG. 16 shows images visually confirmed by moving a video carrier having a video obtained by reducing and compositing five frames of moving images in a certain direction, and FIG. 15 is visually confirmed by appropriately combining the raising and lowering of the video carrier 1. Each image is shown. It should be noted that each of the numbers ~ in the figure is a number attached to the image of each frame for convenience, and the number of seconds is based on the assumption of the display time of each frame image in consideration of the effect on the image display. .

FIG. 17 shows a composite video for representing the images of FIGS. 15 and 16. This composite video is section A ~
It is formed from F and each section is composed of five pixels. Therefore, five different images can be visually recognized by this composite image, and FIG. 16 shows an image obtained by sequentially selectively visually recognizing the pixel groups of each section from one. On the other hand, by appropriately combining these images and adjusting the display (visual recognition) time of each image, a series of continuous images as shown in FIG. 15 can be represented as a moving image. In this case, in order to obtain continuous images, it is necessary to move the image carrier in a complicated manner (up and down in the case shown). FIG. 12 shows the movement amount of the image carrier and the stop time at the moved position for obtaining the continuous images shown in FIG. As is clear from this figure, the movement of the image carrier is quite complicated, and although it is not impossible at all to realize this operation by the above-mentioned cam mechanism, in order to realize it by constant speed rotation of the cam, it is necessary to use the cam itself. It is necessary to form the shape in a complicated manner, and in reality there are many difficulties, and it is extremely troublesome to change the operation even if it is realized.

Next, in the image carrier shown in FIG. 17, each section is composed of 5 frames, but the number of frames can be increased to about 7 frames at maximum, though it depends on the performance of the cylindrical lens group. In this case, from the viewpoint of image representation, a more complicated image structure than the continuous image shown in FIG. 15 is possible, and therefore a more complicated cam structure is required. The image quality of the displayed image is, of course, better when the reduction rate of the target pixel is smaller and the pixel width is wider, and therefore the number of constituent frames of each section is preferably smaller. Therefore, in order to express a complicated moving image with a small number of frames, it is necessary to perform relative movement in a complicated manner, and it is considered that complicated operation control is often required even with a small number of frames.

[Means for Solving the Problems]

The present invention is configured in view of the above-mentioned problems, and makes it possible to represent (visually recognize) the composite image as a moving image with a change by performing the relative movement of the image carrier and the cylindrical lens group in a complicated and reliable manner. It is an object of the present invention to provide a device for doing so.

In order to achieve this object, a driving mechanism that can change the relative movement between the image carrier and the cylindrical lens group at a variable speed and in a driving direction,
The image display device is configured by a control device that controls the drive mechanism, and the display time of each image and the type of the image can be arbitrarily set.

[Action]

The control device issues an operation signal to the drive mechanism based on the operation mode preset and input, and the drive mechanism operates in response to this signal. This operating characteristic is a system called an information cam, which is realized by a method such as software as if it were a complicated mechanical cam.

As a result, either the image carrier or the cylindrical lens group is moved, so that the positions of the two are relatively changed, and specific pixels in each section of the composite image are visually recognized through the cylindrical lens group. By doing so, an image of a specific frame is obtained.

The drive direction of the drive mechanism and the time interval until the next operation are also controlled by so-called information cams such as software cams and picture cams, and the display order and display time of each image are adjusted by this. In addition, continuous images are
Normally, an image composed of adjacent pixels among the pixels of each section is sequentially displayed, but the present invention is not limited to this, and the temporary illumination is turned off, so that another image that is not adjacent is displayed between them. The method is also practicable.

〔Example〕

 Embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 1 shows a first embodiment of the present invention.

A cylindrical lens group 2 is erected and fixed to a base 9 at the forefront (right side of the drawing) of the illustrated apparatus. An illumination light source unit 10 is vertically installed and fixed to the rearmost portion of the base 9 so as to be parallel to the cylindrical lens group 1. A light source such as a fluorescent lamp is housed in the frame of the light source unit 10, and the lighting panel 10a
In this way, the following image carrier is illuminated as uniformly dispersed light.

Reference numeral 1 denotes an image carrier supported by a frame body 3, which is provided between the cylindrical lens group 2 and the illuminating light source section 10 so as to be parallel to both of them. This frame 3 is provided with guide posts 5a and 5b (5b in the figure) as in the device shown in FIG.
(Only shown) and the guide block 4 are supported so as to be able to move up and down. The image carrier 1 supported by the frame 3 is a transparent positive image like a slide film, and a predetermined number of pixels are recorded in each section.

Next, 11 is a rack fixed to the side of the frame 3 supporting the image carrier 1. This rack 11 is preferably a motor (a stepping motor or a digital servomotor,
The stepping motor will be described below as an example) 13 and is engaged with a pinion 12. 14 is this motor 1
A drive unit that directly issues an operation signal to 3
Reference numeral 5 is a control device such as a microcomputer that issues a command signal to the drive unit 14.

In the apparatus having the above configuration, first, the number of frames of each section recorded on the image carrier 1, that is, the number of images that can be displayed, the order of images to be displayed based on the mutual relationship between the contents of each image, and the display of each image. Decide each time. In this case, if the images in the case where the images are sequentially displayed corresponding to the pixel order stored in the respective sections are displayed in the display order ,,,, to perform the same display operation as the cam curve as shown in FIG. 12, for example, In the flat part, the drive pulse of the stepping motor is not emitted, and after a certain period of time, when moving to →, a high-speed pulse train may be sent to a portion having a strong inclination, and a slow pulse train may be sent to a gentle portion. In this way, the method of performing the same control as the cam curve with the software of the computer is "software cam".
It is a type of cam. When the forward / backward motion is set to be performed in the order of →→→→→→, usually, the images adjacent to the front and rear of one image are often displayed as appropriate, but this is not always the case. It is not necessary to have a good video structure. That is, if the moving speed is sufficiently high, the middle image is often unnoticeable even if the moving speed is →. Further, the operation sequence may be determined so that images that are far apart are displayed by appropriately turning on and off the light source unit 10. For example: → turn off → (lights up with display) →
→ Off → (Lit with display) → → Off → (Lit with display).

A software cam having the operation sequence and operation speed characteristics as exemplified above is constructed and the program is input to the control device 15.

The operating state of this device will be described below.

The control device 15 to which the operation sequence corresponding to a specific image carrier is input issues a signal to the drive unit 14 in accordance with the program, and the drive unit 14 further outputs an operation signal corresponding to this signal to the stepping motor 13
Output to. The rotational force of the stepping motor 13 is converted into a vertical movement of the frame body 3 by the engagement between the pinion 12 and the rack 11 fixed to the frame body 3. The image carrier 1 supported by the frame 3 moves up and down together with the frame 3, and the cylindrical lens group 2 sequentially displays images of predetermined frames in response to the up and down movement of the image carrier 1 as if driven by a mechanical cam. . In this case, when the operation program includes a command to turn off / on the light, for example, when displaying a far-away image, the light source unit 10 is turned off / on according to the program.

The operation program for one image carrier is not necessarily limited to one, and another moving image may be configured by appropriately selecting a plurality of operation programs while leaving the image carrier as it is.

Next, when another image carrier is used, the frame 3 is removed from the main body of the apparatus to replace the image carrier, and the operation program corresponding to the new image carrier is input to the control device 15. In the operation program, the position of the image carrier is set by setting the rotation speed of the stepping motor.

FIG. 2 shows a second embodiment.

In this embodiment, the cylindrical lens group 2 is moved up and down.

Guide blocks 4 and 4 similar to the configuration shown in FIG. 13 are fixedly provided on the right side edge with respect to the front surface of the cylindrical lens group 2, and guide posts 5a to be inserted into the guide blocks 4 and 4 are vertically arranged. I am doing it. On the other hand, the guide blocks 4, 4a are also fixed to the left edge portion. Reference numeral 5b is a guide post that is inserted through these guide blocks 4, 4a, and this guide post is rotatable in an upright position,
In addition, a screw portion 5b 'is formed in the lower portion, and this screw portion 5b' is screwed with the guide block 4a.

Reference numeral 16 denotes a servo motor, which transmits its rotational force to the guide post 5b via a rotation transmission mechanism such as a belt and a pulley. 17 is a guide post 5b '
It is a rotation speed detection sensor such as a rotary encoder attached to the.

In the above-described configuration, the servo motor 16 is operated by the operation command output from the control device 15 via the drive unit 14.
Rotates a predetermined number of times. This rotation is transmitted to the guide post 5b. By rotating the guide post 5b, the screw portion 5b '
Cylindrical lens group 2 via a guide block 4a screwed with
Moves up and down. The rotation speed of the guide post 5b is detected by the rotation speed detection sensor 17, and this detection signal is fed back to the control device 15. The controller 15 controls the position of the cylindrical lens group 2 more accurately by this fed back signal. Also in this case, a software cam is used to control the motor drive by comparing the input signal and the target position by software by the sensor.

The configurations shown in the first and second embodiments described above are replaced with mechanical cams having both conventional position information and force transmission mechanism,
A software cam is used as a kind of so-called information cam that has only information. That is, a so-called software that realizes an operating characteristic equivalent to that of a cam drive by using a variable control drive mechanism such as a stepping motor or a servo motor and controlling the drive of this mechanism.
The cam control system is implemented. Therefore, by changing the program, it is possible to immediately realize an arbitrary movement characteristic.

FIG. 3 shows a third embodiment.

In this embodiment, a drive system using a picture cam, which is a kind of information cam, is adopted.
In addition, the frame 3 supporting the image carrier 1 is moved up and down.

That is, the frame 3 has the same structure as the conventional structure shown in the first embodiment and FIG. 13, and the guide block 4 fixed to one side of the frame 3 and the guide block 4 are provided. The guide post 5a is inserted, the guide block 4a is fixed to the other side portion, and the screw rod 18 is screwed into the guide block 4a. 19 is this screw rod 18
Is a stepping motor for rotating the.

Next, reference numeral 20 is a photoelectric sensor.
Is composed of a sensor A (reference numeral 20A) and a sensor B (reference numeral 20B) which are respectively arranged above and below. Reference numeral 21 is a cam cylinder located close to the photoelectric sensor 20, 23 is a constant speed drive motor for rotating the cam cylinder, and 22 is the cam cylinder 2.
It is a picture cam attached to the 0 peripheral wall. This picture cam may be simply drawn on a white paper with black ink or the like.

In this configuration, in order to operate the apparatus, first, the picture cylinder 22 is attached to the cam cylinder 21 and the drive pattern for raising and lowering the image carrier 1 corresponding to the contents of the image carrier 1 is drawn. Next, the constant speed drive motor 23 is operated to rotate the picture cam 22 attached to the cam cylinder 21 at a constant speed. The photoelectric sensor 20 emits an ON signal in a white portion and an OFF signal in a black portion in accordance with the cam pattern which changes with the rotation of the picture cam. Upon receiving this signal, the control device issues a rotation signal to the stepping motor 19, the photoelectric sensor 20 rotates the screw rod 18 so as to correspond to the change of the cam pattern, and the image carrier 1 is moved up and down according to the cam pattern. . As a result, the images are continuously displayed in the order set in advance in the cam pattern. The portion of the picture cam 22 displayed in a mesh pattern indicates a portion with a small amount of light drawn with black ink, and the other portion indicates a portion with a large amount of light. Stepping is performed in correspondence with ON / OFF of each sensor A, B. The motor 19 is operated to cause the image carrier 1 to follow the cam pattern. In addition, O of the photoelectric sensor
The table below shows the elevation pattern of the frame corresponding to N / OFF.

With the above configuration, the elevation control can be easily performed by directly drawing the cam pattern on the cam cylinder or by attaching the cam pattern. Further, in the illustrated configuration, the image carrier 1 is raised and lowered, but it is also possible to raise and lower the cylindrical lens group 2 by using this mechanism.

A linear image sensor may be used instead of the photoelectric sensor. Further, if the cam pattern is expressed as concave or convex with respect to the pattern expression target, a contact type sensor may be used instead of the non-contact type sensor. Not only the picture cam but also the information cam is extremely easy to change the setting of the curved line and is suitable for driving the image carrier.

In each of the embodiments described above, the image carrier 1 is a transparent positive image, and the structure is proved from the back of the image carrier 1, but the image carrier 1 can be an opaque positive image to configure the apparatus.

FIG. 4 is a fourth embodiment and shows the construction of an apparatus using an image carrier made of an opaque positive image.

Reference numeral 24 in the figure denotes an image carrier made of an opaque positive image. The image carrier 24 has pixels arranged by the same construction method as that of the above-mentioned transparent positive image except that it is opaque.

As shown in FIG. 4 (A), the cylindrical lens group 2 is arranged so as to be parallel to the image carrier 24, and further illuminators 25, 25 are arranged in front of the cylindrical lens group 2. With this structure, the light from each lighting fixture 25 passes through the cylindrical lens group 2 as shown in FIG.
4 and the relative movement of the cylindrical lens group 2 and the image carrier 24 makes it possible to visually recognize a specific image.

FIG. 5 shows a fifth embodiment, which is another embodiment using the image carrier composed of the opaque positive image 24 similar to the fourth embodiment.

Reference numerals 26a, 26b, and 26c show the case where monocyte illumination is arranged at substantially the same position as the light source shown by reference numeral 25 in FIG. In this case, the cylindrical lens group 2
It is necessary to individually arrange the cylindrical lenses 2a, 2b, and 2c corresponding to the above. In this way, when light is emitted by individual illumination through each cylindrical lens, each cylindrical lens directs this light flux to a specific pixel (A3 in the case shown) of each section A, B, C ... Of the image carrier 24. , B3, C3, ...) are irradiated, so that the image of a specific frame can be visually recognized by irradiating from the same direction as the line of sight.

FIG. 6 shows a sixth embodiment.

Whereas the above two examples use an opaque positive image,
In this embodiment, the image carrier made of the transparent positive image is used again, but this is shown as a modified example in which the configuration of the light source unit arranged behind the image carrier 1 is changed.

In the light source unit 10, a white light 27a and a colored light 27 are used as light sources.
b are alternately arranged, and the white lamp 27a is turned on / off and the colored lamp 27b is turned on / off by a program previously input to the control device 15, and the color is appropriately changed according to the change of the image. I am allowed to do it. In addition, it is possible not only to change the color but also to turn on / off all the light sources, and by appropriately combining these operations, the effect of the effect can be enhanced. Note that reference numeral 28
Is ON / OFF of each light source according to the command signal of the controller 15.
Is an interface for lighting for performing.

7 to 9 show still another configuration.

In FIG. 7, 29 is a driving roller, 30 is a driven roller, 31 is an image carrier formed in an endless belt shape, and is attached to the driving roller 29 and the driven roller 30. The light source unit 10 is arranged in the parallel portion of the belt-shaped image carrier 31, and the portion of the image carrier 31 located on the front surface is illuminated from the back surface. In this apparatus, the driving roller 29 driven by the stepping motor 19 moves the image carrier 31 according to a preset operation sequence, thereby displaying a moving image. In addition, in the case of this device, it becomes possible to express a moving image that cannot be realized by the above-mentioned sheet-shaped image carrier.

FIG. 8 and FIG. 9 show an example of a moving image representation utilizing the characteristics of the device shown in FIG. In this case, it is not necessary to limit the width of the image expressed through the cylindrical lens group 2 to the width W1 of the cylindrical lens group 2, and the following example also has an image configuration wider than this width W1. Therefore, the image is moved by the movement of the image carrier 31.

For the section located ahead of the moving direction of the image carrier 31, the person M shown in FIG.
A pattern is formed as M2 and M3, and this pattern is arranged as a pixel. That is, each section has three frames, and the pixels of the respective aspects M1 to M3 are allocated and drawn to each of these sections. A string drawn by this person is drawn for the following sections, and flags F1, F2, and F3 are further allocated to the sections at the rear of the sections as pixels for each of the three frames.

The image carrier 31 made up of the above pixels is moved from right to left as indicated by an arrow in the drawing by the driving mechanism to set the pitch P of the cylindrical lens group to 1
When moving stepwise with a moving distance of / 3, a person first appears from the right end of the cylindrical lens group 2, and M1 → M2
→ While repeating the operation of M3, that is, moving while moving toward the left side of the screen. The person is pulling a string, and the flag appears while repeating the operation of F1 → F2 → F3 as the screen progresses, that is, fluttering. Furthermore, as the screen progresses, the person disappears from the screen, and the flag follows it.

In this case, in order to enhance the display effect of the screen, as shown in FIG. 8, the display time of each image A, B, C is, for example, 0.5 seconds,
The time may be appropriately set to 0.5 seconds, 2 seconds, or the like. These settings can be easily implemented by an operation program for the stepping motor 19.

In the illustrated configuration, the image carrier 31 is formed in a simple endless belt shape guided by the driving roller 29 and the driven roller 30, but instead of this, a large number of guide rollers are used to provide a longer endless belt. It is conceivable to display a large number of images by a method such as forming a belt or forming a longer belt shape as a winding method. In the case of the winding method, when the moving distance of the image carrier is measured by the rotation amount of the winding roller, the roller diameter changes depending on the winding amount and the measurement becomes incorrect. It goes without saying that consideration should be given to configuring the settings directly.

18 and 19 show a modification of the configuration shown in FIGS. 4 and 5.

In each of the configuration examples shown in FIGS. 4 and 5, the image carrier is irradiated with the light from the light source through the cylindrical lens group 2, whereas in this example, the light source is the image carrier 1. The light source 3 is provided in a portion other than the light flux region formed between the cylindrical lens group 2 and the image carrier 1 and the cylindrical lens group 2.
Place 2. This light source may be a rod-shaped light source shown in FIG. 4 or a monospherical light source shown in FIG. Reference numeral 33 denotes a shielding means arranged for each light source 32, for preventing the light from the light source from directly irradiating the cylindrical lens group 2. In this configuration, the light source itself is outside the light flux region of the cylindrical lens group 2 and the image carrier 1, so that a specific image can be visually recognized through the cylindrical lens group 2 as in the other configurations.

The case where the device of the present invention is mainly used as an advertising medium has been described above, but this is not intended to limit the function as a display medium, and is used for various teaching materials, for example, in place of slide projection or projector projection at other lectures. In other words, it can be used by the user depending on the purpose, such as in addition to or in combination with this.

The size is also not limited, and it is possible to manufacture various types such as a relatively small tabletop type, a relatively large one for advertising inside the station yard, and a fairly large one for installation on the rooftop of the building. is there.

The main purpose of the present invention is to use a drive mechanism that is variable in drive direction and variable in drive direction as a relative movement mechanism between the image carrier and the cylindrical lens group.
If the cam 8 shown in the figure is driven by a stepping motor or the like and is controlled reversibly and reversibly by the control device, another configuration example of the present invention will be obtained.

〔effect〕

As described above with reference to the respective configuration examples, the present invention provides a mechanism for performing relative movement between the image carrier and the cylindrical lens group, a drive mechanism that is variable in speed and a drive direction is variable, and a control device that controls this drive mechanism. Since the image display device is configured from the above, and the display time of each image and the type of image can be arbitrarily set, it is possible to display a large number of images as well as a relatively small number of frames. While maintaining good image quality, the relative movement of the image carrier and the cylindrical lens group can be performed in a complicated and reliable manner so that it can be represented (visually recognized) as a moving image with changes.

Further, since the relative movement pattern between the image carrier and the cylindrical lens group can be freely set, it is possible to represent a plurality of moving images using the same image carrier.
