Description

A method for representing picture information and a screen}

The present invention relates to a method of displaying image information on an auto-stereoscopic screen according to the end of the main claim and to a screen suitable for carrying out this method according to the end of the auxiliary claim.

In a known type of method, an auto-stereo suitable for simultaneously displaying a plurality of two or more views designed in a multi-person screen and viewed in at least one other observation zone arranged next to each other. Display image information on a stereoscopic screen, which includes a matrix screen with multiple pixels and a beam splitter raster, where the beam splitter raster is used to observe light from the pixels. Suitable for guiding with one of With this type of method known in the art, several stereoscopic fields complementary to each other are displayed on the screen, so that when one eye of one or more observers is present in two different observation zones next to each other For example, one or more observers may autostereoscopically detect a stereoscopic image consisting of two of the fields. As a result, the fields visible in adjacent observation zones are complementarily selected from one another so that some observers next to each other may perceive the scene displayed as a stereoscopic image-with a slightly different perspective.

Known types of screens for carrying out such a method are known and such screens are suitable for simultaneously displaying a plurality of two or more views viewed from an observation zone that is offset by at least one part, The screen includes a plurality of pixels, a beam splitter raster suitable for guiding light from the pixels into at least one observation zone, and a control unit for activating the pixels of the matrix screen according to the image information. . Such screens are also referred to as multi-view displays, multi-user displays or multi-person screens.

It is an object of the present invention to provide a radical method that allows some users of the screen to obtain video content peculiar to each user, such as other television programs, without consulting each other user.

According to the invention, this object is achieved by a method having the features of the main claims together with a screen having the features of the subclaims and the features of the main claims. Advantageous designs and other improvements of the invention will be deduced from the features of the dependent claims.

Thus, due to the fact that the pixels of one screen of the type described above are activated with image information of at least two different scenes, the first observer of the screen may exclusively view the first at least two scenes, and laterally with respect to the first user. In such a way that the second viewer of the moved screen can simultaneously view at least two scenes exclusively by the second, at least two other observers of the screen can view independently selectable content that is specific to each viewer. As a result, of course, two or more scenes are reproduced in this manner on the screen, so that two or more observers may correctly see one of these scenes in three positions placed next to each other. Thereby, it is possible to move images that do not complement each other into stereoscopic images, which are displayed in different scenes as complementary image fields.

Particularly advantageous in the proposed method is that it is possible to use conventional autostereoscopic screens in its practice, and therefore new uses for such screens are proposed in the present invention and the scope of useful applications is expanded.

For example, the matrix screen of the screen to be applied may be a liquid crystal screen (and therefore an LCD display) or an OLED display, and the pixels need not be arranged in rows and columns, but may form other patterns in certain situations. have. With respect to the pixels, subpixels of different three colors are typical, where picture points of each screen are reproduced by a group of at least three subpixels. Typically, the subpixels in this case are arranged in each of the plurality of lines of the matrix screen, in which case the colors alternate in a cyclical sequence.

Beam splitter raster, also called barrier raster, is a slot raster or step raster or hole raster or cylinder lens raster or ball lens. Raster (ball lens raster) or the like.

The method is realized by reproducing image points of each screen by appropriately sized groups of adjacent pixels of the matrix screen, in which case a group assigned to a different scene alternates with each of the plurality of lines of the matrix screen in periodic order. Thereby, groups of adjacent pixels, which are assigned to different scenes, may be directly connected to each other or arranged at a distance that may be separated from each other by one or more blank pixels and selected according to geometric conditions.

Thus it may be successful for each of at least two different scenes to be seen from at least one coherent zone in front of the screen, with no other scenes visible in that zone.

A multiperson screen is used to implement the method, which is suitable for simultaneously displaying a plurality of two views seen from at least one of each coherent observation zone. Zones in which different scenes are visible are designed in a particularly flexible manner, in particular by which they may be designed large enough to be comfortable to observe. Thus, typically, a number of different scenes are displayed on the screen, which are small compared to those described above, and even in certain situations, more than one scene, such as three or four different scenes, is displayed for many observers. At least one of the aforementioned coherent zones, in which the screen is visible, may then be larger than the individual observation zones. Preferably all such areas are larger than the individual observation zones, which may simply be realized when the screen is designed to display very many different views.

The other side of the invention also devises image information of at least one screen, which is read in pixels of the matrix screen, in such a way that it spreads laterally, so that the observation zone lies closer to the screen than the plane with the largest width. The coherent zone in which this scene is seen in the observation zone has the maximum width. In this way, an observer of this screen may be located in front of the viewing plane, and a screen may be designed that allows for more comfortable viewing and allows other observers to choose their positions very freely.

The method may be used irrespective of whether image information of another scene exists only for a mono-picture or for a stereoscopic field complementary to each other with a stereoscopic image. It is possible to devise image information of at least one screen comprising image information of two different stereoscopic fields which are complemented with stereo-images to each other, so that each such field is visible in one of the two coherent zones described above. The screen may be activated so that one of the viewers can detect this stereoscopic image in an autostereoscopic manner.

Another advantageous aspect of the invention is at least one zone in which at least one observer-preferably at each observer-head position or eye position is detected and both eyes of the observer see the scene assigned to this observer. In such a way as to be placed or held in, devise a way in which the activation of the screen is set or changed depending on the detected head position or eye position. In this way the freedom of movement of other observers is advantageously increased. Thereby, a previous blank pixel or a specified pixel or other image point-for example, a pixel so far specified on another screen or another field-is added to these pixel groups and / or outside of these pixel groups. By darkly scanning the placed pixels or by assigning them to different image points, the edge of the pixel group or pixel group that plays one of the image points of the screen assigned to each viewer to track the zone is shifted. May be Thereby, in certain circumstances, it may be possible to track in a precisely graded or quasi stepless manner by redistribution of the intensity at which the pixels at the edges of the pixel group are activated. Thereby, along with the change in distance between the viewer and the screen, the spread of the side of the image point assigned to this viewer-given by one of the pixel groups-may change, while this image point or pixel group is laterally Move. Thereby, it is possible to ensure that image points of different scenes have space next to each other on the matrix screen only by assuming the position of each observer without blocking the view of other observers on the screen.

In essence, it directs light from a pixel to a plurality of pixels, at least one observation zone, and a screen designed to simultaneously display multiple two or more views seen in at least one some laterally shifted observation zone. A matrix screen having a suitable beam splitter raster and a control unit for activating the pixels of the matrix screen according to the image information is suitable for carrying out the above-described method, and in terms of programming techniques, the control unit may be adapted to at least two different scenes. The number is set to disperse the image information of a plurality of images, the number being small compared to the above-mentioned number of pixels in such a way that a coherent zone in front of the screen is assigned to each of these images, and the zones of such scenes are exclusively Visible and at least one is larger than the individual observation zone.

Preferably, the control unit is thereby set up to activate the pixels of the matrix screen in such a way that the image points of each image are reproduced by a group of adjacent pixels of the matrix screen, and the group assigned to the other image is a plurality of lines of the matrix screen. Appear alternately in a periodic order.

In addition, the control unit is spread out laterally such that the coherent zone has a maximum width in the observation plane where the observation zone is located closer to the screen than the plane where the image is visible. As a pixel of the matrix screen, the image information of at least one image may be set.

Two or more stereoscopic images may be among the images described above, the stereoscopic images complement each other with one stereoscopic image of the scene, and the control unit is further set to activate the matrix screen such that these fields are visible in two adjacent zones.

In addition, the screen may have a device for detecting at least one observer's head position or eye position, in which case the two eyes of the observer are placed or maintained in at least one zone in which one of the scenes is visible, The control unit is set to activate the matrix screen according to the detected head position or pixel position.

Specific embodiments of the present invention will be described below with reference to FIGS. 1 to 7.

6 is a corresponding view of the same screen with two of the four observers viewing one stereoscopic image.
7 is a corresponding view of the same screen in a slightly differently activated state.

In fact, it is thought to be an autostereoscopic screen, with a matrix screen 21 having a plurality of subpixels and a plurality of side-by-side observation zones arranged in front of the matrix screen 21. A screen comprising a beam splitter raster 22 suitable for guiding light exiting a subpixel of the matrix screen 21 to another subpixel of is shown in FIG. The numbered observation zone 23 here corresponds to the twenty video channels 1-20 of the screen. Beam splitter raster 22 may also be referred to as barrier raster.

The matrix screen 21 is a liquid crystal screen including a plurality of subpixels in a plurality of lines, in which red, green and blue subpixels appear alternately in a periodic order in each line. Instead of this, for example, the matrix screen may use an OLED display. Each image point played back on the matrix screen 21 is formed by a group of pixels of several subpixels and spans three lines so that each desired color is faithful to the color, regardless of the width of the image point or pixel group. May be reproduced. One of the lines of the matrix screen 21, spanning 18 subpixels 24, is shown in detail in FIG. 3 in five different states, denoted by letters a through e, in each case four such groups of pixels. (M1, M2, M3 and M4) are shown.

For example, the beam splitter raster 22 can be designed as a slot raster or rod lens raster, in which the colored subpixels 24 are suitably arranged. The slot or rod lens of 22) is preferably inclined about 20 ° with respect to the vertical line. In another embodiment, the beam splitter raster 22 may also be designed as a step raster, hole raster or spherical lens raster.

Finally, the screen is provided for activating the matrix screen 21 with respect to programming techniques and to display the subpixels 24 of the matrix screen 21 according to the image information, in particular according to the image information of other stereoscopic fields. It includes a control unit 25, which may be activated.

In the operating mode, which is not the focus of interest here, the screen is displayed as a conventional multilateral screen by means of image information of twenty three-dimensional fields complementary to each other, which are reproduced in the subpixels 24 of the matrix screen 21 in a periodic order. It can be activated, so that one of these stereoscopic half images is seen in each of the side-viewing observation zones 23. Some people are equal in plane 26 with the maximum width (typically the width of the average eye distance of about 65 mm) with distance from the matrix screen 21 by nominal observation zone 23. An autostereoscopic image of the screen may also be detected.

Here, another method of displaying image information on an autostereoscopic screen will be described. In this way, in the present case, the first observer 27 of the screen is exclusively the first scene, the second observer 28 of the screen is exclusively the second scene and the third observer 29 is exclusively the first scene. In three ways, and also in such a way that the fourth observer 30 can view the fourth scene exclusively, the subpixel 24 of the matrix screen 21 is separated from four other scenes and activated with image information. With respect to the scene, the images can be shifted, which are completely different and in particular complementary to one another, not complementary to stereo-images. In this case, a control unit 25 related to programming techniques is provided to disperse the image information of the four scenes in which the image is designated as the subpixel 24, so that a coherent zone 31 on the front of the screen is provided. Assigned to each of the images or screens, this scene is seen exclusively in that zone. Thus, in the present case, all four zones 31 are larger than the individual observation zones 23.

In this case, the control unit 25 activates the subpixels 24 of the matrix screen 21 in such a manner that four image points of each image are reproduced by a group of adjacent subpixels 24, thereby each image and each image. The screen is exactly visible in one of the zones 31, in which groups assigned to different images appear alternately in periodic order on each of the lines of the matrix screen 21. Thereby, groups of adjacent subpixels 24 assigned to different images and different scenes are directly connected to one another or, if desired, to one another by some blanked subpixel 24. It may be separated. With respect to the pixel groups M1, M2, M3 and M4 shown in Fig. 3, the width of this group is in this case 3 to 5 sub pixels 24. However, although only one line of the matrix screen 21 is shown in detail, the subpixel groups M1 to M4 span three continuous lines.

In FIG. 1, observers 28, 29 so that the eyes of observers 28, 29, 30 have a distance to the screen or more precisely to the plane defined by the screen as compared to the nominal viewing distance d. , 30) is located. In spite of this, in order to ensure that the eyes of these observers 28, 29 and 30 are completely located in each zone 31, the image information of the scene assigned to these observers 28, 29 and 30 is Written in subpixels 24 of the matrix screen 21 in such a way that it spreads laterally so that the zone 31 in which this scene is visible lies at the maximum in the viewing plane 32, closer to the screen than the plane 26. Has a width. The image points or groups of pixels (M2, M3 or M4) that average over the complete line of the matrix screen 21 to form images of these three scenes are slightly less than the width of 20 consecutive subpixels 24. It has a larger average distance (defined as the distance between the surface center of gravity or between the center of brightness of gravity or between the right edge or left edge of the pixel group M2, M3 or M4). Since the first observer 27 is located in front of the plane 26, the same may be applied to the pixel group M1 as well. The zone 31 of the third observer 29 occupies the image channels 9 to 12 at the left image edge (at the top of FIG. 1), on the contrary the image channel at the right image edge (at the bottom of FIG. 1). It can be easily recognized that spreading laterally in FIG. 1 by the fact that it is covered by the image points seen in this scene or pixel group M3, occupying 11 to 14.

The screen of FIG. 1 also includes a device 33 for detecting the head position or eye position of the observers 27, 28, 29 and 30. For example, the apparatus 33 may include two video cameras arranged to be offset from each other; And a known image recognition program. The activation of the matrix screen 21 is such that the two eyes of each observer 27-30 are placed in a zone 31 and the constant movement of the head is maintained in the zone 31. Is set or changed by the control unit 25 according to the head position or the eye position of the observers 27 to 30 detected by, and the scenes assigned to each observer 27, 28, 29, 30 in the zone are see. To this end, the edges of the pixel groups M1 to M4 and also the pixel groups M1 to M4 themselves are added to the previous blank subpixel 24 or to these pixel groups M1, N2, M3 and M4. Of subpixels 24 assigned to different image groups (and other images) and pixel groups M1, M2, M3 and M4 assigned to blank or other image points (and thus other images). It is moved by subpixels 24 which are placed at different positions at the edges.

This is shown by way of example in FIGS. 2 and 3. As such, the repeating feature shown in FIG. 1, which is the same in FIGS. 4 to 7, is provided with the same reference numerals, and FIG. 2 shows the situation after the observers 27 to 30 have moved (but to be more visible). Only the control unit 25 and the device 33 are shown). In comparison with FIG. 1, the viewpoints of observers 27-30 have moved slightly to the right, and the fourth observer 30 has also changed the distance to the screen. In FIG. 1, it may also be seen how the four zones 31 are tracked to ensure that the two eyes of the observers 27-30 are included in each of these zones 31, as in the previous case. For example, in FIG. 3, from the top to the bottom, at five consecutive points in time a to e, how the pixel groups M1 to M4 are moved by redistribution and intensity (brightness of light) of the image information. It is shown if their size changes in tracking zones 31. As a result, a weighting function for the image points of four different images is shown in the form of a bar chart, and the value of the image defined for each subpixel 24 is assigned to each image point of each image. It is multiplied by the value of the brightness resulting from the image point. In spite of the finite magnification of the subpixel 24, redistribution and movement may occur in a quasi-stepless manner. The lateral movement of the observers 27-30, the change in the distance between the observers 27, 30 and the plane defined by the screen is compensated by the described movement of the edges and image points of the pixel groups M1-M4, In the first case, the image point is moved sideways, and in the second case, the above-described spreading in the lateral direction is adopted, whereby each observation plane 32 is moved.

Each observer 27-30 sees a mono-picture as described in FIGS. 1 and 2. However, the screen may also be operable to allow more than one person to see scenes unique to each person as well as to sense them as stereoscopic images. For example, FIG. 4 shows the case where the first observer 27 and the second observer 28 see the screen, with the two eyes of each of these observers 27, 28 being two adjacent zones 31, 31 ′. And the right stereoscopic field is visible in each right zone 31 and the left stereoscopic field 31 is visible in each left zone 31 '. In this case also, the image information of the other scene is written in a subpixel 24 of the matrix screen 21 so that the first observer 27 can see only the first scene, and the second observer 28 Only the second scene that can be distinguished from this can be seen. Thereby, the image information for each of these scenes is complemented with stereoscopic images of the first scene or the second scene and two stereoscopic half-images which can be detected autostereoscopically by the observers 27, 28. (semi-picture) image information is included.

The changed situation is shown in FIGS. 5 to 7, so that the matrix screen 21 is activated in a modified form, and each of the three to four observers 27 to 30 of the screen can see the individual scene.

Therefore, the situation of the observers 27 and 28 of FIG. 4 is applied to four observers 27-30 in the situation of FIG. In each case, each of these observers 27 to 30 sees a stereoscopic image of a scene unique to each observer 27, 28, 29, 30. Two observers 27, 30 are slightly in front of plane 26, while observers 28, 29 have their eyes in plane 26. In this case, the zones 31, 31 ′ designated to the eyes of these two observers 28, 29 are precisely formed by one of the observation zones 23, in particular the zone at the second observer 28 is an image. By the channels 9 and 10, the zones in the third observer 29 are also formed by the image channels 12 and 13.

Two adjacent zones 31, 31 ′ are assigned to only two observers 27, 30 and one of the two complementary fields is visible in the zone so that these observers 27, 30 correspond to observers 27, 28 of FIG. 4. The situation where a stereoscopic image can be viewed is shown in FIG. 6. In contrast, in the larger zone 31 where the eyes of the two observers 28, 29 can be seen as mono-pictures, the scenes peculiar to each of these observers 28, 29, are shown in FIGS. 1 and 2. It is located like the situation.

Another possible situation appears in FIG. 7 showing the first observer 27, the second observer 28 and the third observer 29 of the same screen. As described with respect to FIG. 4, here, two zones 31, 31 ′ are provided to the second observer 28, where two fields of a scene peculiar to the observer 28 can be seen to view a stereoscopic image. According to the zones 31, 31 ′ of the previous figure and the description of FIGS. 1 to 3, these zones 31, 31 ′ track the movement of the observer 28 so that the observer's right eye is always a zone 31. ), The left eye is always kept in zone 31 '. Similarly, the third observer 29, which tracks the constant movement of the head and places the head in a large zone 31, sees a mono-picture of the scene peculiar to the observer 29. Conversely, the zone assigned to the first observer 27 spans five adjacent observation zones 23-corresponding to the imaging channels 1-5, while operating normally for the screen of the type shown, Five different stereoscopic fields are visible, each of which can be seen accurately in one of these five observation zones 23, and the fields visible in adjacent observation zones 23 complement each other to form a stereoscopic image together. This stereoscopic image in this case represents a scene unique to the first observer, and when the observer moves to the right or to the left, the scene can be viewed by the observer from a slightly different direction. Therefore, when the first observer 27 considers the movement, if the observer 27 leaves the aforementioned zone to the left, only the activation of the matrix screen 21 changes. In addition, if the zone has more observation zones 23 in certain situations, some people may also -multi-view displays or multi-user displays, which are usually operated in a manner. The same scene may be detected autostereoscopically, while other scenes are visible to the observers 28 and 29 simultaneously.

As shown in Figs. 4 to 6, as long as at least a stereoscopic image is visible, a subpixel of the matrix screen 21 in the pixel group, in which the control unit 25 relating to the programming technique reproduces an image point of one of the fields; 24) may be installed to increase the intensity in such a way that the intensity can be maximized at a location within the two zones 31 and 31 ', thereby increasing the brightness. The positions are distanced from each other by the eye distance of each observer 27, 28, 29, 30.

Referring to the arrows shown in FIG. 1, with respect to programming techniques, the control unit 25 senses at least one image data and / or description data 34 of a scene and is the first image of one or more images reproduced therefrom. It can be installed to generate data, so that generated image data of different contents can be designated in another zone 31 or another zone 31 '. Thereby the image data and / or description data 34 in certain situations may also be entered in encrypted form and later decrypted in the control unit 25.

In certain situations, image information of other scenes may be specified in the zone 31 or the zone 31 ′ according to the input variable 35, which may be input by the user. The user-thus each observer 27-30-may infinitely select from the available scenes.

  If the image data is calculated from the descriptive data 34, the control unit 25 also has at least one virtual camera position or, depending on the at least one command variable, for which the image data is generated with respect to the programming technique. It may be installed to change at least one stereo-base. Thereby, the distance or side head position of the observer 27, 28, 29 or 30 on the screen can be considered as a command variable, which can be determined by the device 33. Alternatively, or in addition, the other input variable 35 may serve as a command variable input by the user for this purpose, such as a remote controller or an input device for an interactive game.
