Description

  The present invention relates to a stereoscopic display device that performs stereoscopic display by displaying a plurality of parallax images to an observer, and particularly relates to a stereoscopic display device that supports data with various numbers of eyes.

(1) Description of conventional binocular stereoscopic display means:
A so-called binocular stereoscopic display device that displays two parallax images on the left and right sides of the observer's eyes has been widely used because of its simple configuration. As the direct-view type binocular stereoscopic display device, a parallax barrier method and a lenticular method are typical and widely known.

  For the parallax barrier method, see S.A. H. KaplaN, “Theory of Parallax Barriers”, J. Am. SMPTE, Vol. 59, no. 7, pp. 11-21 (1952). According to this method, a stripe image in which at least left and right parallax images are alternately arranged among a plurality of parallax images from a plurality of viewpoints has a predetermined opening provided at a position away from the image by a predetermined distance. Stereoscopic viewing can be performed by observing a parallax image corresponding to each eye with the left and right eyes through a slit (referred to as a parallax barrier).

  In the lenticular method, a lenticular having a large number of kamaboko-shaped lenses is provided on the front surface of the display, and the images entering the left and right eyes are separated spatially to allow the user to observe a stereoscopic image.

(2) Explanation of 2D / 3D mixed display:
In order to achieve compatibility with a two-dimensional image (one viewpoint image) display device, a parallax barrier is electronically generated by a transmissive liquid crystal display device or the like, and the shape and position of the barrier pattern are variably controlled electronically. Such a three-dimensional display device is disclosed in Japanese Patent Laid-Open No. 3-119889 (Japan Broadcasting Corporation, Hadano) and Japanese Patent Laid-Open No. 5-122733 (Japan Broadcasting Corporation, Hadano).

  FIG. 14 is a basic configuration diagram of a stereoscopic image display device disclosed in Japanese Patent Laid-Open No. 3-119889. This stereoscopic image display device includes a transmissive liquid crystal display device 901 that displays an image, and a transmissive liquid crystal display element that is disposed on the transmissive liquid crystal display device 901 via a spacer 902 having a thickness d. The transmissive liquid crystal display device 901 displays a parallax image captured from two directions or multiple directions as a vertical stripe image. A parallax barrier pattern is formed at an arbitrary position on the barrier surface by designating an XY address in the electronic parallax barrier 903 by a control unit such as the microcomputer 904, and in accordance with the principle of the parallax barrier method. Enables stereoscopic viewing.

  FIG. 15 is a configuration diagram of a display unit of a stereoscopic image display device configured by a liquid crystal panel display and an electronic parallax barrier disclosed in Japanese Patent Laid-Open No. 3-198989. 925 is sandwiched between two polarizing plates 911, 918 and 912, 928, respectively. In this apparatus, when performing two-dimensional image display, the display of the electronic parallax barrier pattern is stopped, and the whole area of the image display area of the electronic barrier 903 is made colorless and transparent, thereby providing two-dimensional display. Realization of compatibility.

  Japanese Patent Laid-Open No. 5-122733 discloses a configuration in which a barrier stripe pattern can be generated only in a partial region of an electronic parallax barrier 903 composed of a transmissive liquid crystal display element as shown in FIG. An example is disclosed in which a 3D image and a 2D image can be displayed together in the same plane.

(3) Description of multi-view stereoscopic display device:
As described above, in the binocular stereoscopic display device using two right and left parallax images, the stereoscopic observation region that can be stereoscopically observed is narrow. In order to overcome this disadvantage, attempts have been made for a multi-view stereoscopic display device that displays three or more parallax images to an observer.

  A typical method is to project a parallax image from a plurality of projection display devices onto a lenticular screen. In addition, a stereoscopic display device that performs multi-view display by combining a flat display such as a liquid crystal display device or a plasma display with a parallax barrier or lenticular is also known. In general, a stereoscopic display device that performs multi-view display using a lenticular or parallax barrier deteriorates the resolution only in the horizontal direction, and the resolution balance in the horizontal and vertical directions is deteriorated. Examples in which the degradation of only the horizontal resolution is dispersed in the vertical direction and the resolution degradation is averaged are proposed in Japanese Patent Registration No. 02967622 (Sharp) and Japanese Patent Application Laid-Open No. 2001-212465 (Hit Design).

(4) Known Example 1 of GUI of a stereoscopic display device (Japanese Patent Laid-Open No. 10-74267, Canon):
In JP-A-10-74267 (Canon, Osaka) and JP-A-10-232665 (Canon, Osaka), is a computer system equipped with a graphical user interface (hereinafter referred to as GUI), and is it possible to display three-dimensionally for each display object? A configuration for determining whether or not to perform display control is described. This disclosed example describes that the brightness of the display device is adjusted according to the number of eyes when the display object is multi-view display, but details of multi-eye parallax image processing are not mentioned in detail.
“Theory of Parallels Barriers” Japanese Patent Laid-Open No. 03-119889 JP 05-122733 A Japanese Patent Registration No. 02966762 Japanese Patent Laid-Open No. 2001-212465 Japanese Patent Laid-Open No. 10-074267 Japanese Patent Laid-Open No. 10-232665

The problems in the above prior art can be summarized as the following (1) to (3).
(1) Even if data other than the parameters that can be displayed (such as the number of eyes) is input, the display can be made according to the stereoscopic display device.
(2) 3D display parameters can be set according to the request of the observer.
(3) Implement a GUI to make it easy to set the parameters for stereoscopic display and make the system easy to use.

  In order to solve the above problems, the stereoscopic display device of the present invention is a stereoscopic display device capable of stereoscopic display with only one eye number, and whether or not the display target data of the display device is capable of stereoscopic display. The image processing apparatus further includes a stereoscopic image determination unit and an eye number determination unit for determining whether or not the stereoscopic image determination unit can display a stereoscopic image, whether the parallax image data has a predetermined number of eyes.

  As described above, even when an image having a different number of eyes is input from the video source, the image can be displayed with the predetermined number of eyes of the stereoscopic display device. In addition, in a stereoscopic display device in which the number of eyes can be selected, stereoscopic display according to the request of the observer is possible. Furthermore, it becomes a user-friendly system by implementing the GUI.

  The stereoscopic display device according to the present embodiment is a stereoscopic display device capable of stereoscopic display with only one eye number, and the stereoscopic image determination means for determining whether or not the display target data of the display device can be stereoscopic display; When it is determined by the stereoscopic image determination means that stereoscopic display is possible, it further includes eye number determination means for determining whether or not the parallax image data has a predetermined number of eyes. Here, when the number of eyes is determined to be out of the predetermined number by the eye number determination means, eye number conversion means for generating a predetermined number of eyes from data outside the predetermined number of eyes is provided. Further, the eye number conversion means performs thinning, interpolation, or extrapolation of the parallax image. The eye number converting means generates three-dimensional data from two or more parallax images, and further generates a predetermined parallax image.

  Further, the stereoscopic display device according to another aspect of the present embodiment is a stereoscopic display device that can display with several eyes, and a stereoscopic image determination unit that determines whether or not the display target data of the display device can be stereoscopically displayed. When the stereoscopic image determining means determines that stereoscopic display is possible, the eye number determining means further determines whether or not the parallax image data matches one of several eyes. In such a stereoscopic display device, when there is a matching number of eyes by the eye number determination means, it is desirable to perform stereoscopic display with the matching number of eyes. Furthermore, when the number of eyes is determined to be outside the predetermined number by the eye number determination means, it is desirable to perform the eye number conversion means with the number of eyes closest to the predetermined number of eyes.

  The stereoscopic display device according to another aspect of the present invention is a stereoscopic display device that can display with several eyes, and can set stereoscopic display parameters according to the request of an observer. Here, the stereoscopic display parameters are the number of eyes and the parallax image resolution.

  Here, the (stereoscopic display) system of the present embodiment is performed by a graphical user interface in which setting of stereoscopic display parameters is implemented in a system in which the above-described stereoscopic display device and a computer are connected. Here, the values that can be set for the parameters are specified in the graphical user interface. Also, in the graphical user interface, the relationship between the stereoscopic display parameters having the opposite characteristics is specified.

  In addition, the stereoscopic display device according to another aspect of the present embodiment can set a stereoscopic display parameter for each window in a stereoscopic display device that can display a plurality of windows that simultaneously display a plurality of objects. Here, the stereoscopic display parameter can be switched between when the window is active and when it is inactive. Here, the range of the stereoscopic display parameter applied by the pointing device can be designated.

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

(First embodiment)
A first embodiment will be described with reference to FIGS. In the first embodiment, the stereoscopic display optical system is described as a parallax barrier type multi-view stereoscopic display device including a parallax barrier and a liquid crystal display device, but the configuration of the optical system may be other types.

(1) Overall configuration of the first embodiment:
FIG. 1 is a diagram showing an optical configuration of the first embodiment. FIG. 1A is a perspective view, and FIG. 1B is a plan view thereof. In the figure, reference numeral 101 denotes an optical member that constitutes a multi-view stereoscopic display of a predetermined number of eyes (hereinafter, N eyes), for example, 4 eyes or 8 eyes, by a parallax barrier. Reference numeral 102 denotes a display panel of a liquid crystal display device that generates a predetermined parallax image, and 103 denotes a backlight that is a light source of the liquid crystal display device. 50R and 50L are an observer's right eye and left eye.

  FIG. 2 is a block diagram showing the configuration of the computer system in the first embodiment. The signal supply to the stereoscopic display device is not limited to the computer. Reference numeral 111 denotes a host computer for handling a stereoscopic image, and reference numeral 112 denotes a display driver for driving the stereoscopic display device 113. In FIG. 2, the object analysis unit 114, the N-eye parallax image generation unit 115, and the N-eye parallax image generation unit 116 are included in the display driver 112, but even if part of this function is in the host computer 111 and the stereoscopic display device 113. Good. The object analysis unit 114 analyzes the type of data of the display object, generates parallax image data by the N-eye parallax image generation unit according to the type, and draws it by the N-eye parallax image drawing unit 116. Reference numeral 117 denotes an image display unit corresponding to the liquid crystal panel in FIG. Reference numeral 118 denotes an N-eye parallax optical system that displays an N-eye image including a parallax barrier and the like.

(2) Explanation of video source:
Even in a general two-dimensional display or a stereoscopic display device of the present invention, there are various types of video sources used. Hereinafter, typical examples are listed below.

[1] Two-dimensional image data Generally, a television signal without depth information, a digital camera reproduction image, a computer image, etc. [2] Three-dimensional data Data having depth information created by computer graphics (hereinafter referred to as CG) or 3D CAD, It is typically composed of polygons. There are also two-dimensional images with depth information (depth map) added.
[3] Parallax image data There are right-eye and left-eye binocular stereo images and multi-eye image data of three or more eyes. As a stereoscopic image, a binocular stereo image is most popular.

(3) Signal processing flow of the display driver 112:
FIG. 3 is a flowchart for explaining the function of the display driver 112. Step S101 is a stereoscopic image determination step for determining whether the video source has three-dimensional data. Step S102 is an N-eye image generation step that proceeds when the three-dimensional data is determined in S101. In S102, a conventionally known means may be used, and a method of generating a parallax image for N eyes using CG data and a virtual camera may be used. If it is not three-dimensional data in step S103, the process proceeds to step S105 if it is a parallax image in the parallax image determination step for determining whether or not the video source is parallax image data. If not, the process proceeds to step S104. In step S104, “other processing” described later is performed. Step S105 is an eye number determination step for determining whether the parallax image is an N-eye parallax image suitable for the stereoscopic display device of the first embodiment. If there are N eyes, the process proceeds to S107. If so, the process proceeds to S106. Step S106 is an eye number conversion step for synthesizing an image with the number of eyes other than N eyes into an N eye image, as will be described later. Step 107 is N-eye parallax image synthesis processing for synthesizing an image to be displayed on the display panel. In the case of a parallax barrier, the N-eye parallax image synthesis processing 107 performs stripe synthesis in which parallax images of N eyes are repeatedly arranged in sequence. If the data has already been subjected to the synthesis process, step S107 can be omitted. Step S108 is the final stage of displaying an image on the display panel.

(4) “Other processing” in step S104:
Step 104 is processing when the video source is not three-dimensional data or a parallax image. This step 104 includes the case where the video source is a two-dimensional image. In the case of a two-dimensional image, if a stripe image without parallax is displayed in step S108, two-dimensional display is possible although there is resolution degradation. Further, the parallax barrier 101 is configured to be capable of generating and disappearing with a transmission type spatial modulation element such as an LCD, and when the barrier is extinguished in the case of a two-dimensional image, a normal two-dimensional display is obtained. If the process as described above is performed on the entire screen, 2D / 3D switching display is performed, and if it is partially performed, 2D / 3D mixed display is performed.

  If it is neither 3D nor 2D data, an error message or the like may be displayed.

(5) “Eye number conversion” in step S106:
Step 106 is a step of generating an N-eye image from a parallax image having the number of eyes different from N (hereinafter referred to as a K-eye parallax image). If the K-eye parallax image is larger than the N-eye parallax image, the (K-N) eye parallax image may be thinned out. Further, when the K-eye parallax image is smaller than the N-eye parallax image, a (K-N) eye parallax image is newly generated by image processing such as interpolation or extrapolation to form an N-eye image. For an image that has already been subjected to stripe image synthesis or the like, the above processing is performed after generating a K-eye parallax image by reversing the synthesis processing. Furthermore, three-dimensional data may be generated from two or more parallax images by image processing such as corresponding point extraction, and a parallax image from an arbitrary direction may be generated.

  As described above, as described in the first embodiment, the type of data of the video source is determined, and by performing the processing in each case, N-eye stereoscopic display becomes possible.

(Second embodiment)
A second embodiment will be described with reference to FIGS. In the second embodiment, a parallax barrier system that is part of a stereoscopic display optical system can be electronically generated and extinguished and the number of eyes can be switched. The configuration of the optical system can be realized by other methods as long as the display can be switched between 3D display and 2D display or mixed display.
The same reference numerals as in the first embodiment perform the same functions.

(1) Generation of an arbitrary number of eyes:
FIG. 4 is an explanatory diagram showing the optical configuration of the second embodiment. The difference from the first embodiment is an electronic barrier 201 that can electronically control the opening pattern instead of the parallax barrier 101. The electronic barrier 201 is composed of a spatial modulation element that can control light transmission and light shielding like a liquid crystal display device. This electronic barrier is controlled by the parallax control unit 202. FIG. 5 shows an example of a barrier opening pattern generated in the electronic barrier 201, which is for two eyes, four eyes, and eight eyes from the top. If the resolution of the electronic barrier 201 is infinite, any number of barrier openings can be generated, but in reality, the number of eyes that can be generated is limited because the electronic barrier has a pixel structure. Assume that the limited number of eyes of the barrier opening pattern is {N0, N1, N2,... NN} = NN. Note that 2 may be included in the NN. A backlight emission control system 203 is a stereoscopic display device with stable brightness when the parallax is adjusted according to the aperture pattern.

(2) System configuration:
FIG. 6 is a system configuration diagram showing the configuration of the second embodiment. 211 is a display driver, 212 is a stereoscopic display device of the second embodiment, 213 is a screen control unit that performs a coordinated operation of a parallax image and an electronic barrier based on a signal from an object analysis unit, and 214 is a parallax image of N eyes An N-eye parallax image rendering unit 215 for displaying is a parallax control unit that controls the generation of an electronic barrier.

(3) Signal processing flow of the display driver 211:
FIG. 7 is a flowchart for explaining the function of the display driver 211. Step S101 is a three-dimensional data determination step for determining whether or not the video source is three-dimensional data having three-dimensional data, and step S202 is a NN eye image generation step that proceeds when it is determined as three-dimensional data in S101. It will be described later. In S202, a parallax image for N eyes is generated using conventionally known three-dimensional data and a virtual camera. In step S103, the process proceeds to a case where the video source is not parallax image data in the parallax image determination step for determining whether or not the video source is parallax image data. If not, the process proceeds to step S206 of other processing described later. Step S204 is a step of drawing a stripe composition and a parallax barrier pattern. Step S205 is the final stage of displaying an image on the display panel and an opening pattern on the electronic barrier.

(4) Explanation of Step 202 “NN Eye Image Generation”:
In the second embodiment, the number of eyes displayed on the stereoscopic display device can be set to some extent as in the third embodiment described later. The NN eye image generation unit in step S202 displays a parallax image using a conventionally known technique such as CG according to the number of eyes selected by the observer.

(5) Step S203 “NN eye number conversion”:
If the number of eyes in the parallax image matches one of the NNs, the process proceeds to the next step S204. If the number of eyes in the parallax image does not match one of the NNs, the parallax image is processed with the nearest number of eyes in the NN using a thinning-out or interpolation or extrapolation technique.

(6) Description of Step S206 “Other Processing”:
Step 206 is processing when the video source is not three-dimensional data or a parallax image. This step 206 includes the case where the video source is a two-dimensional image. In the case of a two-dimensional image, the electronic barrier 201 can be configured and controlled so as to be transparent, and normal two-dimensional display can be performed.

  As described above, as described in the second embodiment, the type of data of the video source can be determined, and N-eye stereoscopic display according to the request of the observer and the number of eyes of the data can be performed.

(Third embodiment)
A third embodiment will be described with reference to FIGS. In the third embodiment, a user interface for controlling the stereoscopic display device of the second embodiment with a GUI of a computer system will be described. The same reference numerals as those in the first and second embodiments perform the same function.

(1) Explanation of stereoscopic display parameters:
As represented by a parallax barrier or lenticular multi-view stereoscopic display device, the multi-view display device has the following multi-view parameters (hereinafter referred to as stereoscopic display parameters).
-Number of eyes-Resolution of parallax image (Single parallax image displayed in multiple eyes-Interocular pitch (Parallax image display interval)
-Stereoscopic observation area (main lobe area where continuous observation is possible)
The relationship is inversely proportional to the number of eyes and the resolution of the parallax image per eye. When the number of eyes is increased, the resolution is decreased, and conversely, when the number of eyes is decreased, the resolution is increased.

  The relationship between the number of eyes and the stereoscopic observation area is also inversely proportional. When the number of eyes is increased, the main lobe (observation area) is widened. Conversely, when the number of eyes is reduced, the main lobe is narrowed.

  Although the interocular pitch and the stereoscopic observation area are in a proportional relationship, the smoothness of motion parallax is sacrificed when the interocular pitch is increased.

(2) Application of multi-view stereoscopic display device:
Various fields are assumed as applications of the stereoscopic display device. For example, for medical use or the like, detailed observation of the affected area is required, and a higher parallax image resolution is preferred. In order to increase the parallax image resolution, it is better to reduce the number of eyes. In home games played by multiple people, there is a tendency to prefer a wider observation area than resolution, and it is better to increase the number of eyes. When a stereoscopic image that differs depending on the viewing direction, that is, when motion parallax display is required, a smaller interocular pitch is preferred.

  As described above, it is desired to set the stereoscopic display parameters such as the number of eyes depending on the usage form. The stereoscopic display parameter setting means will be described below.

(3) GUI screen description:
FIG. 8 is an explanatory diagram of a GUI operation screen mounted on a computer system. In the figure, reference numeral 300 denotes the entire GUI screen of the stereoscopic display device of the present invention. 301 is a title bar indicating the name and version of the application software, 302 is a menu bar for the observer to operate, 303 is a pull-down menu with an expanded menu bar function, 304 is a pointer operated with a pointing device such as a mouse, 305 And 306 are display objects.

  Typical GUI components include controls provided as standard in Microsoft Visual C ++ (WiNdows application development software), but other components may be used.

(4) 2D display settings:
Stereoscopic images have greater fatigue and discomfort than two-dimensional display because eye focus adjustment and convergence do not match. In addition, the feeling of fatigue or discomfort is greatly different among individuals, and some observers do not like stereoscopic display, and it is necessary to set to display only a two-dimensional display.

  FIG. 9 is a diagram illustrating the setting of only the two-dimensional display in the stereoscopic display according to the preference of the observer. In the figure, 305 is a setting dialog, 305 and 307 are GUI component radio buttons, and 308 is an eye number setting slide switch. In FIG. 9, only “two-dimensional display” is set by enabling “set to 2D display” of the radio button 306 of the setting dialog 305.

(5) Stereoscopic display parameter setting:
FIG. 10 shows an example in which the stereoscopic display parameter is set according to the preference of the observer. “Set the number of eyes” of the radio button 307 of the setting dialog 305 is enabled, and the number of eyes is set by operating the eye number setting slide switch.

  FIG. 10 shows a state where four eyes are set. Since the setting of the number of eyes is limited as described in the second embodiment, a means capable of selecting the selectable items is preferable. An input box or the like that can input an arbitrary integer is not preferable in this embodiment.

  The stereoscopic display parameters that can be set include, in addition to the number of eyes, parallax image resolution, interocular pitch, stereoscopic observation region, and the like, and can be set in the same manner as described above. In addition, since the number of eyes and the parallax image resolution are in an inversely proportional relationship, a GUI that can clearly indicate this relationship is desirable. FIG. 11 is an explanatory diagram of stereoscopic display parameters having an interaction such as the number of eyes and the resolution of parallax images. In the figure, 310 is a stereoscopic display parameter setting dialog, 311 is a radio button for selecting the number of eyes setting, 312 is a slide switch for setting the number of eyes, 313 is a radio button for selecting setting of the parallax image resolution, and 314 is a parallax image. It is a slide switch that sets the resolution. When the radio button 314 is enabled, the parallax image resolution can be set. In the example shown in the figure, the “low” resolution setting is “8 eyes”. When this is set to “medium” resolution, the slide switch for the number of eyes is automatically moved, such as “four eyes” when the resolution is “high”, and “two eyes” when the resolution is “high”. If the number of eyes radio button is selected, the reverse operation is performed. In this way, the interrelationship of the stereoscopic display parameters can be shown to the observer.

(6) Multi-window setting:
FIG. 12 is an explanatory diagram in which this embodiment is applied to a multi-window system. In the figure, 320 and 321 are stereoscopic display windows capable of stereoscopic display, and 322 is a two-dimensional display window for performing only two-dimensional display of characters and the like. Thus, an environment in which two dimensions and three dimensions are mixed is obtained. The windows 320 and 321 can individually set the stereoscopic display parameters as described above. For example, the window 320 can be set to two eyes, and the window 321 can be set to eight eyes. In FIG. 12, the window 321 is in the window active state, and the window 320 may be displayed two-dimensionally or three-dimensionally. Workability may be improved by changing the setting of the stereoscopic display parameter between the active state and the inactive state, which is effective.

(7) Specify the range of the stereoscopic display parameter with the pointer:
FIG. 13 is an explanatory diagram of an example in which a range of stereoscopic display parameters is designated by a pointing device such as a mouse. In FIG. 13, if a range around the display object 305 is displayed, and then the 3D display parameters are displayed by applying the above-described method, 3D display with partially different 3D display parameters becomes possible.

(8) When GUI is not used:
There is a set numerical value of the number of eyes in the stereoscopic display device with the stereoscopic display parameter by GUI.

  As described above, the stereoscopic display parameters can be changed according to the viewer's preference as in the third embodiment. Further, although the means for changing the stereoscopic display parameter by using the GUI has been described, a stereoscopic display parameter may be set by providing a DIP switch or the like in the stereoscopic display device.

  The above-described embodiments can be arbitrarily combined within a consistent range.
