Description

  The present invention relates to a display device that presents an image with a visual stereoscopic effect.

  One of the major themes for display devices such as televisions, mobile phones, and personal computers is the realization of a stronger sense of reality, and a three-dimensional effect is one of the elements that make up reality.

  As a technique aiming at realizing a three-dimensional effect, a moving image display device capable of obtaining a visual three-dimensional effect, such as a 3D liquid crystal display, is now widely used. Many of these use binocular parallax to present different moving images to the left and right eyes, thereby allowing the viewer to perceive a visual stereoscopic effect. For example, in Patent Document 1, in a stereoscopic image display apparatus that performs stereoscopic viewing by separating an image having binocular parallax and guiding it to an observer, the distance between the condensing points of the image having binocular parallax is reduced. As a result, a stereoscopic display can be realized even on a small display, and a stereoscopic view can be perceived, and a stereoscopic view can be perceived, thereby reducing a sense of discomfort associated with the transition between the stereoscopic view and the reverse view state. Is described.

  In addition, although different from the visual three-dimensional effect, Patent Document 2 has a configuration in which a touch-sensitive touch panel is installed on the surface of the display, and visual information displayed on the display is output as vibration or unevenness on the touch-sensitive touch panel. Is described.

  Patent Document 3 describes an information output device that outputs tactile information such as a material feeling of an image as unevenness information together with an image by an unevenness information output unit installed on the surface or bottom surface of the image display unit.

  In recent years, development of a flexible display that is very thin and lightweight and can be bent like paper has been progressing. For example, although not commercialized at present, Non-Patent Document 1 describes a flexible display that can expand and contract like rubber. Thus, display devices have evolved into various forms, and display forms have been diversified.

  Further, as a method for extracting stereoscopic information from a planar image, Patent Document 4 describes a method capable of recognizing a shadow region and a non-shadow region from one image and extracting a shadow boundary.

  However, 3D displays that are widely used nowadays have the problem that the range of angles in which a stereoscopic effect can be obtained is limited due to the characteristic of presenting different moving images to the left and right eyes, and the perceptual depth and actuality. Due to the difference in the distance from the screen, there are problems that the user feels uncomfortable and that symptoms such as headache and nausea occur.

  Moreover, although patent document 1 reduces the discomfort of the transition between the stereoscopic vision and the reverse vision state in the naked-eye 3D display, the fundamental problem is that the angle range in which the stereoscopic effect can be obtained is limited. Is not solved.

The present embodiment relates to a display device 1 including a flexible display 22 that can be expanded and contracted. The display device 1 further includes a touch panel 21 that can be expanded and contracted. When the user operates the touch panel 21, the image A presented on the flexible display 22 is changed, and the visible unevenness B corresponding to the image A is displayed on the image A. It is possible to superimpose and present.

  Here, “corresponding to the image A” means the unevenness B that is presented superimposed on the image A when the image A showing the car is displayed on the flexible display 22 as shown in FIG. Indicates that it is a model of the car. Further, the “visible unevenness B” means an unevenness B that allows the user to perceive a three-dimensional effect in the unevenness image C in which the image A and the unevenness B are superimposed by superimposing the unevenness B on the image A. Show.

(Configuration of display device 1)
FIG. 1 is a functional block diagram of a display device 1 according to this embodiment. The display device 1 includes all display devices including a flexible display, such as a television, a personal computer, a tablet terminal, and a mobile phone.

  As shown in FIG. 1, the display device 1 includes an input / output panel 2, a control unit 3, and a storage unit 4.

  The input / output panel 2 includes an interface for a user to input, and presents an image and visible irregularities. The input / output panel 2 includes a touch panel 21, a flexible display 22, and an unevenness forming part 23.

  The touch panel 21 is a means that enables the operation of the display device 1 when the user touches it, and can be expanded and contracted.

  The flexible display 22 is a means for displaying the image information acquired from the control unit 3, and can be expanded and contracted.

  The unevenness forming part 23 forms unevenness that is visible on the flexible display 22. In the present embodiment, the unevenness corresponding to the content of the image is formed on the flexible display 22 so as to overlap the image. Specifically, as shown in FIG. 3A, the unevenness B corresponding to the shape of the car indicated by the image A is superimposed on the image A to present the unevenness image C. The concavo-convex forming portion 23 is installed on the side opposite to the display surface of the flexible display 22, and can form a visible concavo-convex B on the entire screen of the flexible display 22. The unevenness forming elements of the unevenness forming part 23 do not have to correspond to the pixels of the flexible display on a one-to-one basis, and it is sufficient that the pixels of several pixels correspond to one unevenness forming element. The detailed structure of the unevenness forming part 23 will be described later.

  Note that when the two-dimensional plane expressed by the flexible display 22 at the time when the unevenness is not formed is used as a reference surface, the unevenness forming unit 23 determines the output state of each unevenness forming element, that is, the height between the continuous unevenness forming elements. By setting the numerical value to increase or decrease stepwise, it is possible to form an inclined reference plane that is tilted while the reference plane remains flat. Thereby, the two-dimensional plane expressed by the flexible display 22 can be directed to the front of the user.

  The control unit 3 controls the functions of the above members and controls the driving of the display device 1.

  Next, a detailed configuration of the control unit 3 will be described. The control unit 3 includes an operation acquisition unit 31, an application control unit 32, an image information processing unit 33, an uneven information processing unit (unevenness information output unit) 34, a display control unit 35, and an unevenness control unit 36. .

  The operation acquisition unit 31 acquires user input to the touch panel 21. Specifically, an operation position is detected based on user input information from the touch panel 21, and if the operation is for an application, the input information is transmitted to the application control unit 32.

  The application control unit 32 controls the activation and termination of the application according to the input information from the operation acquisition unit 31. In addition, the image information processing unit 33 is notified of image information to be presented on the application in accordance with the input information.

  The image information acquisition unit 33 requests and acquires image information indicating the image A to be displayed on the flexible display 22. Specifically, an image / unevenness information data set which is a data set of image information notified from the application control unit 32 and unevenness information associated with the image information is stored in the image / unevenness information database 41. Request and get. The image / unevenness information data set is preferably a data set in which pixel information and unevenness information in an image are associated with each other, but is not limited thereto. Further, the image information processing unit 33 transmits the unevenness information acquired in association with the image information to the unevenness information processing unit 34.

  The concavo-convex information processing unit 34 generates concavo-convex information that is a source of a signal for the concavo-convex control unit 36 to instruct the concavo-convex forming unit 23 to form concavo-convex. The unevenness information processing unit 34 includes an unevenness information acquisition unit 341.

  The unevenness information acquisition unit 341 acquires the unevenness information associated with the image information from the image information acquisition unit 33. Based on the uneven information acquired from the image information processing unit 33, uneven information is generated so as to correspond to the image information generated by the image information processing unit 33.

  The concavo-convex information is information for giving information in the height direction to each area of the image A which is a plane, and thereby making the image A a concavo-convex image C. The data structure of the unevenness information will be described. As an example, the unevenness information includes the z-axis (height) as the coordinate value of the dividing intersection when the image A is divided vertically (y-axis) horizontally (x-axis) at a predetermined interval (for example, the pitch of the unevenness forming elements). ) Data in which direction values (z values) are associated with each other. As another example, the z value may be associated with the coordinate value of each pixel for all pixels of the image A. In this case, the concavo-convex information processing unit 34 calculates, for example, an average value of z values associated with pixels in a region corresponding to a certain concavo-convex forming element based on the pitch of the concavo-convex forming element, and calculates the average value. The z value of the forming element may be converted. Thereby, it is possible to flexibly cope with a change in the correspondence between the unevenness forming element and the pixel (for example, the number of pixels in the region corresponding to the unevenness forming element).

  As a concrete example of the unevenness information, if the image A is a photograph, the depth measurement result by the infrared sensor at the time of shooting may be held, or the distance measurement result to the object by multi-lens camera shooting may be held. May be. If the image A is a three-dimensional computer graphics image, the unevenness information may be set based on the three-dimensional coordinate value of each pixel of the image A.

  The display control unit 35 displays the image A on the flexible display 22. Specifically, the image information acquired from the image information processing unit 33 is converted into a signal for displaying as an image and transmitted to the flexible display 22.

  The unevenness control unit 36 causes the unevenness forming unit 23 to form the unevenness B. Specifically, the unevenness information is acquired from the unevenness information processing unit 34 and a signal instructing the formation of the predetermined unevenness is transmitted to the unevenness forming unit 23.

  The storage unit 4 holds data and programs referred to in each process performed by the control unit 3. The storage unit 4 includes an image / unevenness information database 41.

  The image / unevenness information database 41 is a database that holds an image / unevenness information data set in which image information indicating the image A displayed on the flexible display 22 is associated with unevenness information indicating the unevenness output by being superimposed thereon. It is. The image / unevenness information data set is preferably a data set in which pixel information and unevenness information in an image are associated with each other, but is not limited thereto.

  Here, the data structure of the image / unevenness information data set will be described. As an example, the image / unevenness information data set may be a data set including the image information and the unevenness information. In this case, the image information acquisition unit 33 acquires the image / unevenness information data set, extracts the image information and the unevenness information separately from the image / unevenness information data set, and further extracts the unevenness information as the unevenness information. The data is transmitted to the processing unit 34. As another example, the image / unevenness information data set may be a data set in which the image information and the unevenness information are separated by embedding IDs. In this case, the image information acquisition unit 33 acquires the image information first, and acquires the unevenness information identified by the same ID based on the ID embedded in the image information.

Although not shown, an imaging unit or a communication unit may be provided, and image information may be acquired via the imaging unit, or image information or unevenness information may be acquired via the communication unit.
(Processing in the display device 1)
FIG. 2 is a flowchart showing a flow of processing performed by the display device 1. Here, it is assumed that the processing is started from a state where a predetermined application is activated.

  First, the operation acquisition unit 31 determines whether a touch panel operation has been detected (S101). Specifically, it is determined whether or not a user input signal from the touch panel 21 has been acquired. When the touch panel operation is not detected (No in S101), the operation acquisition unit 31 waits until the touch panel operation is detected.

  When the touch panel operation is detected (Yes in S101), the operation acquisition unit 31 transmits information indicating the operation position on the touch panel 21 to the application control unit 32, and the application control unit 32 adds the operation position information to the operation position information. In response, the image information processing unit 33 is notified of image information to be displayed on the application.

  When a touch panel operation is detected (Yes in S101), the image information acquisition unit 33 acquires an image / unevenness information data set (S102). Specifically, the image / unevenness information data set including the image information notified from the application control unit 32 is requested from the image / unevenness information database 41 and acquired. At this time, the image information acquisition unit 33 also transmits the unevenness information in the image / unevenness information data set to the unevenness information processing unit 34. The unevenness information processing unit 34 may directly acquire the image / unevenness information data set from the image / unevenness information database.

  Subsequently, the image information acquisition unit 33 acquires image information corresponding to the operation position (S103). Specifically, image information corresponding to the operation position is acquired from the image / unevenness information data set. Further, the image information acquisition unit 33 notifies the uneven information processing unit 34 of image information to be output as a display image in real time. As a result, it is possible to present the image and the unevenness on the flexible display.

  Next, the unevenness information acquisition unit 341 of the unevenness information processing unit 34 acquires unevenness information corresponding to the image information (S104: unevenness information acquisition step). Specifically, the unevenness information corresponding to the output image information is acquired from the image / unevenness information data set acquired from the image information processing unit 33.

  Subsequently, the display control unit 35 and the unevenness control unit 36 superimpose and output the image information and the unevenness information (S105: unevenness control step). Specifically, the image information generated by the image information processing unit 33 in step S103 is acquired, and based on this, an instruction to display the image A on the flexible display 22 is issued. On the other hand, the concavo-convex control unit 36 acquires the concavo-convex information generated by the concavo-convex information processing unit 34 in step S104, and issues an instruction to form the concavo-convex B on the concavo-convex forming unit 23 based on the acquired information.

  Next, the flexible display 22 and the concavo-convex forming part 23 present the image A and the concavo-convex B superimposed on each other (S106: concavo-convex forming step). Specifically, the flexible display 22 displays the image A based on the image display signal received from the display control unit 35, while the unevenness forming unit 23 is based on the unevenness forming signal received from the unevenness control unit 36. To form irregularities B. Thereby, the superimposed display of the image A according to the position where the user operated the touch panel 21 and the unevenness B corresponding to the image is realized. That is, various uneven images C are presented on the flexible display 22 depending on the position operated by the user's finger.

Example 1
As an example of the present embodiment, as shown in FIG. 3B, in an application such as drawing software, a place where the user touches the touch panel 21 is detected, and a paint at the time of drawing is displayed on the corresponding place of the flexible display 22. It is conceivable to present a concavo-convex image C with a concavo-convex B similar to a handwriting such as.

  Here, the concavo-convex information processing unit 34 may change the concavo-convex information to be output according to the operation speed on the touch panel 21. For example, the height and width of the unevenness B that is presented superimposed on the image A may be changed according to the touch panel operation speed of the user. Thereby, the user can visually recognize the concavo-convex image C with a three-dimensional effect as if the paint was actually painted with a brush according to the drawing speed.

  The touch panel 21 may include a pressure sensor, and the unevenness information processing unit 34 may change the unevenness information to be output according to the touch intensity detected by the pressure sensor. For example, the height and width of the unevenness B that is presented to be superimposed on the image A may be changed according to the touch intensity of the user. Thereby, the user can visually recognize the concavo-convex image C accompanied by a three-dimensional effect as if the paint was actually painted with a brush according to the writing pressure.

(Example 2)
As another example of the present embodiment, as shown in FIG. 3C, an image A in which a ripple spreads from a location where the user touches the touch panel 21 is displayed, and an unevenness B corresponding to the image A is displayed. A configuration in which the superimposed rippled uneven image C is presented while being moved is conceivable.

  Here, the video representing the spread of ripples can be considered as a sequence of still images corresponding to each frame, and can be realized by executing the processing of steps S103 to S106 for each frame.

  With this configuration, the display device 1 can present the concavo-convex image C using a flexible display not only for still images but also for moving images. Therefore, the user can also view moving images with a stereoscopic effect. Is possible.

(Example 3)
As yet another example of the present embodiment, as shown in FIG. 3 (d), an abacus, a flick, etc. are displayed on the flexible display 22, and the ball is reproduced as a concavo-convex image C, and the ball is played with a finger. The concavo-convex image C showing the bounced ball may be moved.

  With this configuration, the user can visually recognize the concavo-convex image C with a three-dimensional feeling such as actually handling an abacus or an oyster.

Example 4
As yet another example of the present embodiment, when the keyboard is displayed on the flexible display 22 and the key is reproduced in the uneven image C, and the key is touched with a finger, the uneven state of the key changes from convex to concave. Also good.

  With this configuration, the user can operate the keyboard with a stereoscopic effect like an actual keyboard.

(Configuration of display device 12)
FIG. 4 is a functional block diagram of the display device 12 according to the present embodiment. For convenience of explanation, members having the same functions as those in the drawings described in the first embodiment are given the same reference numerals, and descriptions thereof are omitted.

  As shown in FIG. 4, the display device 12 further includes a human sensor 6 and a first unevenness information correction unit 343 in addition to the display device 1 of the first embodiment, and acquires unevenness information. The concave / convex information generating unit 342 is included in the unit 341. In the description of the present embodiment, the touch panel 21, the specific application, and the database that stores the image information and the unevenness information in association with each other are not described. Therefore, the touch panel 21, the application control unit 32, and the image / unevenness information database. Although 41 is not illustrated, these may also be provided in this embodiment. Moreover, the output part which united the flexible display 22 and the uneven | corrugated formation part 23 was made into the output panel 2a.

  The human sensor 6 is a sensor that detects the presence position of a person (user), and is a sensor using infrared rays, ultrasonic waves, visible light, or the like. The human sensor 6 preferably detects the position of the person in the display screen side of the display device 12, that is, in a range where the flexible display 22 can be browsed.

  The unevenness information generation unit 342 generates unevenness information corresponding to the image displayed on the flexible display 22. Specifically, image analysis processing is performed on the image information acquired from the image information acquisition unit 33, and unevenness information corresponding to the image information is generated.

  As the image analysis processing performed by the unevenness information generation unit 342, a known technique described in Patent Document 4 is applied, the shadow area in the image A is recognized, and the shadow area actually becomes a recess on the flexible display 22. The unevenness information may be generated so as to be a shadow.

  The first unevenness information correction unit 343 corrects unevenness information output to the unevenness control unit 36. Specifically, on the basis of the user position information from the human sensor 6, the concave / convex image C presented on the flexible display 22 in which the image A and the concave / convex B are superimposed faces the user 60 so as to face the front. The unevenness information acquired from the information acquisition unit 341 is corrected.

  The uneven | corrugated information after the correction | amendment by the 1st uneven | corrugated information correction | amendment part 343 is the height (z-axis) direction linked | related with the coordinate value (x, y) of each division (pixel) described in the said 1st Embodiment. In addition to the information, inclination information for forming the inclination reference plane described in the description of FIG. 1 may be included.

  FIG. 5 is a flowchart showing a flow of processing performed by the display device 12 according to the present embodiment. Here, it is assumed that the process starts from a state where the user is about to select to display a desired image on the flexible display 22 so as to be superimposed on the unevenness.

  First, the operation acquisition unit 31 determines an image A to be displayed (S201). Specifically, user input information for determining the image A to be displayed is acquired. The user may select the image A by selecting a thumbnail or a file name. It should be noted that by treating the video as a sequence of a plurality of still images, it is possible to apply the subsequent processing not only to the still images but also to the moving images. The user input information acquired by the operation acquisition unit 31 is transmitted to the image information acquisition unit 33 as display image determination information.

  Next, the image information acquisition unit 33 acquires image information (S202). Specifically, the image information including the image information corresponding to the image A determined in step S201 is acquired from the storage unit 4, and the image information is transmitted to the uneven information processing unit.

  Subsequently, the unevenness information generation unit 342 of the unevenness information acquisition unit 341 generates unevenness information corresponding to the image information (S203). Specifically, an image analysis for extracting three-dimensional solid information is performed on the image information acquired in step S202, and uneven information corresponding to the image information is obtained based on the obtained three-dimensional information. Generate.

  Next, the human sensor 6 detects the user position (S204). Specifically, the position of the user 60 existing in a range where the flexible display 22 can be browsed is detected. The detected user position information is transmitted to the first unevenness information correction unit 343. The time for executing step S204 is not limited to this, and may be any time as long as it is a stage before the correction of the unevenness information according to the user position described later.

  Next, the first unevenness information correction unit 343 corrects unevenness information according to the user position (S205). Specifically, the unevenness information acquired from the unevenness information acquisition unit 341 is corrected based on the user position information acquired from the human sensor 6 to generate corrected unevenness information. The uneven information after the correction is uneven information that outputs the image information and the uneven information generated in step S203 in a state of facing the user at the position indicated by the user position information. is there.

  Next, the display control unit 35 and the unevenness control unit 36 superimpose and output the image information and the corrected unevenness information (S206). Specifically, the display control unit 35 acquires the image information acquired by the image information acquisition unit 33 in step S202, and issues an instruction to display an image on the flexible display 22 based on the acquired image information. On the other hand, the unevenness control unit 36 acquires the corrected unevenness information generated by the first unevenness information correction unit 343 in step S205, and issues an instruction for the unevenness forming unit 23 to form unevenness based on the acquired unevenness information. For example, when the unevenness B corresponding to the image A displayed on the flexible display 22 in the upper diagram of FIG. 6A is a shape reflecting the three-dimensional structure of the building in the image A as shown in the lower diagram, FIG. As shown in (b), the projections and depressions B are formed in a shape in which the projections and depressions B are formed on the inclined reference plane so that the projections and depressions B shown in the lower part of FIG. .

  Next, the flexible display 22 and the concavo-convex forming part 23 present the image A and the concavo-convex B superimposed on each other (S207). The processing here is the same as step S106 in the first embodiment. However, the unevenness B formed here is based on the unevenness information after the correction by the first unevenness information correction unit 343.

  Next, the human sensor 6 detects the user position again (S208). Specifically, the user position is detected again to confirm whether the user position has changed, that is, whether the user 60 has moved.

  Subsequently, the human sensor 6 determines whether or not the user position has changed (S209). Specifically, it is determined whether the user position detected in S207 is different from the user position detected in S204. This determination is preferably performed based on a preset threshold value. Here, if it is determined that the user position has changed (Yes in S209), the human sensor 6 transmits new user position information to the first unevenness information correction unit 343, and based on this, step S205 and subsequent steps. The process is performed again. That is, when the user 60 moves from place to place as shown in FIG. 6B, the unevenness B formed on the flexible display 22 changes according to the movement. On the other hand, if it is determined that the user position has not changed (No in S209), the human sensor 6 waits until the next user position detection.

  In the present embodiment, the configuration for generating the unevenness information by image analysis has been described. However, the image to be displayed may be an image stored in the image / unevenness information database 41, in which case image analysis or the like is performed. Since complicated processing is not required, it is possible to present the concavo-convex image C according to the user position even in a display device that does not have high calculation processing capability.

(Configuration and effect)
As described above, the display device 12 according to the present embodiment includes the human sensor 6 that detects the user position and the first unevenness information correction unit 343, so that a flexible display is provided according to the detected position of the user 60. It is possible to change the concavo-convex B to be output by superimposing the image A on the image 22.

  Thereby, the user 60 can always visually recognize the uneven | corrugated image C with the optimal three-dimensional effect, without being limited in the angle of the eyes | visual_axis with respect to the flexible display 22. FIG.

  Furthermore, by providing the concavo-convex information generation unit 342 that generates concavo-convex information by image analysis processing, the concavo-convex image C can be presented even for the image A that is not associated with the concavo-convex information in advance.

  Thereby, the user can visually recognize an arbitrary image A that is not registered in the database with a stereoscopic effect.

[Third Embodiment]
(Outline of display device 13)
Still another embodiment of the present invention will be described with reference to FIGS. The present embodiment relates to a display device 13 including a flexible display 22 that can be expanded and contracted. The display device further includes an illuminance sensor 7, and according to the position of the light source 90 detected by the illuminance sensor 7, the unevenness B corresponding to the image A to be presented on the flexible display 22 in a superimposed manner is changed. It is what makes it possible. In particular, it is possible to change the unevenness B so that the region to be emphasized as a shadow in the image A is actually a shadow by the light from the light source 90.

  In this embodiment, as shown in FIGS. 9A to 9C, based on the position of the light source 90 detected by the illuminance sensor 7, a shadow formation that is an area to be emphasized as a shadow in an image presented on a flexible display. An example in which the unevenness information output to the flexible display is changed so that the region 91 is actually shaded by the light from the light source 90 will be described.

(Configuration of display device 13)
FIG. 7 is a functional block diagram of the display device 13 according to the present embodiment. For convenience of explanation, members having the same functions as those in the drawings described in the first and second embodiments are denoted by the same reference numerals and description thereof is omitted.

  As shown in FIG. 7, the display device 13 includes an illuminance sensor 7 and a second concavo-convex instead of the human sensor 6 and the first concavo-convex information correction unit 343 provided in the display device 12 of the second embodiment. The information correction unit 344 is included.

  The illuminance sensor 7 is a sensor that detects the position of the light source 90 and is a sensor that uses a phototransistor, a photodiode, or the like. The illuminance sensor 7 preferably detects the position of the light source 90 in the front side of the display device 13, that is, in a range where the flexible display 22 can be irradiated. It should be understood that the light source 90 includes not only spontaneous light emitters but also objects that can illuminate the flexible display 22 by reflection.

  The second unevenness information correction unit 344 corrects unevenness information output to the unevenness control unit 36. Specifically, based on the light source position information from the illuminance sensor 7, a region (shadow formation region 91) to be emphasized as a shadow in the image A displayed on the flexible display 22 blocks light from the light source 90 with a convex portion. The unevenness information is corrected so as to be a shadow.

  The unevenness information after correction by the second unevenness information correction unit 344 is the height (z-axis) direction associated with the coordinate values (x, y) of each section (pixel) described in the first embodiment. In addition to the information, it may include inclination information for forming the inclination reference plane described in the description of FIG. 1 or protrusion protrusion information for further protruding the protrusion.

  FIG. 8 is a flowchart showing a flow of processing performed by the display device 13 according to the present embodiment. Here, it is assumed that the process starts from a state in which the user intends to select to display a desired image A superimposed on the unevenness B on the flexible display 22.

  The processes in steps S301 to S303 are the same as steps S201 to S203 in the second embodiment.

  Next, the operation acquisition part 31 determines the shadow formation area 91 (S304). Specifically, in the concavo-convex image C, a user input for determining a shadow forming area 91 that is an area to be emphasized as a shadow is acquired. The user may select the shadow formation area 91 by dragging and dropping on the image A. The user input information acquired by the operation acquisition unit 31 is transmitted to the image information acquisition unit 33 as shadow formation region determination information. The image information acquisition unit 33 transmits shadow formation region information in which the shadow formation region is associated with the pixel position in the image to the unevenness information processing unit 34 based on the shadow formation region determination information.

  Next, the illuminance sensor 7 detects the light source position (S305). Specifically, the position of the light source 90 existing in a range where the flexible display 22 can be irradiated is detected. The detected light source position information is transmitted to the second unevenness information correction unit 344. The time for executing step S305 is not limited to this, and any time may be used as long as it is a stage before correction of the unevenness information corresponding to the light source position described later.

  Next, the second unevenness information correction unit 344 corrects unevenness information according to the light source position (S306). Specifically, the unevenness information acquired from the unevenness information acquisition unit 341 is corrected based on the light source position information acquired from the illuminance sensor 7 and the shadow formation region information acquired from the image information acquisition unit 33. Protrusion information is generated. The corrected unevenness information is such that the shadow formation area 91 outputs the image information and the unevenness information generated in step S303 so that the shadow formation region 91 is actually shadowed by shielding light from the light source 90. Information.

  Next, the display control unit 35 and the concavo-convex control unit 36 superimpose and output the image information and the concavo-convex information after correction (step S307). Here, the display control unit 35 acquires the image information acquired by the image information acquisition unit 33 in step S302, and issues an instruction to display the image A on the flexible display 22 based on the acquired image information. On the other hand, the unevenness control unit 36 acquires the corrected unevenness information generated by the second unevenness information correction unit 344 in step S306, and issues an instruction to form the unevenness B on the unevenness forming unit 23 based on the acquired unevenness information. For example, the unevenness B corresponding to the image A displayed on the flexible display 22 in the upper diagram of FIG. 9A is a shape reflecting the three-dimensional structure of the building in the image A as shown in the lower diagram, and If the area corresponding to the shadow is defined as the shadow forming area 91, the unevenness B that tilts the flexible display 22 is formed so that the light from the light source 90 to the shadow forming area 91 is shielded as shown in FIG. 9B. . Or you may shield the light from the light source 90 by making a convex part protrude more like FIG.9 (c).

  Next, the flexible display 22 and the unevenness formation 23 present the image A and the unevenness B superimposed on each other (S308). The processing here is the same as step S106 in the first embodiment. However, the unevenness B formed here is based on the unevenness information after the correction by the second unevenness information correction unit 344.

  Note that the determination of the shadow formation area 91 in S304 may be determined by image analysis (S203) performed by the unevenness information generation unit 342, regardless of user input. That is, an area determined as a shadow area in the image A may be used as the shadow formation area 91. According to the above configuration, the display device 13 can emphasize a shadow in the uneven image C without requiring a user operation for designating the shadow formation region 91.

  Further, depending on the situation, the shadow area in the image A and the shadow formation area 91 may not necessarily match. For such a case, the image information acquisition unit 33 uses the method described in Patent Document 4 after the above-described determination is performed by the unevenness information generation unit 342, so that the shadow information in the image A is detected. You may correct | amend a pixel value and you may produce | generate image A 'that all the surfaces of the object which the content of the image A shows are shining. According to the above configuration, the uneven image C presented on the flexible display 22 is formed with a shadow only by the light from the light source 90, so that it is possible to present the uneven image C without a sense of incongruity.

  Further, the unevenness information may be corrected at any time according to the change in the light source position by the same procedure as Steps S207 to S208 in the second embodiment.

Similarly to the first and second embodiments, the image A to be displayed may be an image stored in the image / unevenness information database 41.
(Configuration and effect)
As described above, the display device 13 according to the present embodiment includes the illuminance sensor 7 that detects the light source position and the second unevenness information correction unit 344, so that the shadow forming region is determined according to the detected position of the light source 90. The unevenness B that is superimposed on the image A and output on the flexible display 22 can be changed so that 91 is actually shaded by the light from the light source 90.

  Thereby, the user 60 can visually recognize the concavo-convex image C with a stronger stereoscopic effect.

  Furthermore, by eliminating the shadows in the image A by image correction, the shadows due to only the light from the light source 90 can be presented in the concavo-convex image C.

  Thereby, the user can visually recognize the uneven | corrugated image C with a three-dimensional effect without a more uncomfortable feeling.

(Modification)
As an example in which the second and third embodiments are combined, a configuration in which the illuminance sensor 7 in FIG. 7 is replaced with the human sensor 6, as shown in FIGS. Accordingly, an example in which the shadow forming area 91 is perceived as a shadow by changing the unevenness B output on the flexible display 22 can be considered.

  According to the said structure, even if a light source position changes, the user can always visually recognize the appropriate uneven | corrugated image C. FIG.
