DETAILED DESCRIPTION OF THE INVENTION

[0017] The present invention will be described below through embodiments of the invention, but the following embodiments do not limit the scope of the invention according to the claims. Furthermore, not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0018] 1 schematically shows an example of an image display device 100. The image display device 100 includes a flexible display 110, a deformation unit 120, and a control unit 200. The image display device 100 may include a recognition unit 130. The image display device 100 may include a directional speaker 140. The image display device 100 may include a plurality of directional speakers 140. The image display device 100 may include a communication unit 150.

[0019] The flexible display 110 may be a tough display. The flexible display 110 may be a flexible display. The flexible display 110 may be a so-called flexible organic electroluminescence (EL) display. The flexible display 110 may be a so-called flexible liquid crystal display. The flexible display 110 may be a so-called electronic paper display.

[0020] The flexible display 110 may have any size. For example, the flexible display 110 has a size that allows it to be placed on a desk or the like. For example, the flexible display 110 has a size that allows it to be used as signage in stations, stores, facilities, offices, and the like. The image display device 100 may include a plurality of flexible displays 110. The image display device 100 may divide and display an image on the plurality of flexible displays 110. This allows the overall display size to be increased.

[0021] The deformation unit 120 deforms the shape of the flexible display 110. The deformation unit 120 is configured, for example, by a deformable housing on which the flexible display 110 is installed and a servo motor that deforms the housing. The deformation unit 120 may have any structure as long as it can deform the flexible display 110 into a shape that protrudes from the display surface side or a shape that retracts from the display surface side. Examples of the shape of the flexible display 110 include, but are not limited to, a shape when the flexible display 110 is viewed from above, i.e., a shape in which the transverse cross section of the flexible display 110 is V-shaped, Λ-shaped, S-shaped, L-shaped, or wavy, and a shape when the flexible display 110 is viewed from the side, i.e., a shape in which the longitudinal cross section of the flexible display 110 is V-shaped, Λ-shaped, S-shaped, L-shaped, or wavy.

[0022] The recognition unit 130 recognizes the situation around the flexible display 110. For example, the recognition unit 130 recognizes the situation of people around the flexible display 110. The recognition unit 130 may recognize the number of people viewing the flexible display 110, their standing positions, their relationship (parent and child, lovers, etc.), gender, age, physique (height, weight), facial expression, head direction, gaze direction, emotions, etc. The recognition unit 130 recognizes, for example, the situation of objects around the flexible display 110. For example, the recognition unit 130 recognizes the wind around the flexible display 110. For example, the recognition unit 130 recognizes light incident on the flexible display 110.

[0023] The recognition unit 130 may include an imaging unit. The recognition unit 130 may include an imaging unit that can capture an image of the viewable range of the display surface of the flexible display 110. For example, the recognition unit 130 includes an omnidirectional camera. An omnidirectional camera may also be called a 360-degree camera, a spherical camera, or the like. The recognition unit 130 may include a sensor that recognizes the surroundings using a laser. For example, the recognition unit 130 includes a LiDAR (Light Detection and Ranging).

[0024] The recognition unit 130 may include a wind speed sensor. The recognition unit 130 may recognize the wind speed and direction around the flexible display 110 using the wind speed sensor.

[0025] The recognition unit 130 may include an optical sensor. The recognition unit 130 may recognize light incident on the flexible display 110 using the optical sensor.

[0026] The directional speaker 140 delivers sound in a specific direction or within a specific area. The image display device 100 may include multiple directional speakers 140 that output sound in different directions based on the position of the image display device 100. The image display device 100 includes, for example, multiple directional speakers 140 arranged at positions corresponding to respective positions on the display surface of the flexible display 110. As a specific example, the image display device 100 includes a directional speaker 140 arranged at a position corresponding to the center of the display surface of the flexible display 110 and outputting sound in a direction facing the display surface of the flexible display 110, a directional speaker 140 arranged on the right side as viewed from the display surface of the flexible display 110 and outputting sound in a direction facing the display surface of the flexible display 110 with directionality toward the right, and a directional speaker 140 arranged on the left side as viewed from the display surface of the flexible display 110 and outputting sound in a direction facing the display surface of the flexible display 110 with directionality toward the left. This allows different sounds to be conveyed to a person located directly in front of the flexible display 110, a person located to the right of the flexible display 110, and a person located to the left of the flexible display 110.

[0027] The communication unit 150 communicates with other devices. For example, the communication unit 150 communicates with other video display devices 100. The communication unit 150 may communicate with other devices via a network. The network may include a mobile communication network such as an LTE (Long Term Evolution) communication system, a 4G (4th Generation) communication system, a 5G (5th Generation) communication system, a 3G (3rd Generation) communication system, and a 6G (6th Generation) communication system or later. The network may include a LAN (Local Area Network). The network may include the Internet. The network may include a so-called cloud network. The communication unit 150 may be wirelessly connected to the network via a wireless base station, a Wi-Fi (registered trademark) access point, a wireless LAN router, or the like, or may be wired.

[0028] The control unit 200 performs various controls. For example, the control unit 200 controls the display of the flexible display 110. For example, the control unit 200 causes the flexible display 110 to display an image.

[0029] The control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 in accordance with at least one of the surrounding situation of the flexible display 110 and the display content of the flexible display 110 .

[0030] For example, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 in accordance with the surrounding conditions of the flexible display 110 recognized by the recognition unit 130. For example, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 in accordance with the recognition result of a person viewing the flexible display 110 by the recognition unit 130. For example, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 in accordance with the recognition result of an object around the flexible display 110 by the recognition unit 130. For example, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 in accordance with the recognition result of wind around the flexible display 110 by the recognition unit 130. For example, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 in accordance with the recognition result of light incident on the flexible display 110 by the recognition unit 130.

[0031] For example, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 in accordance with the display content of the flexible display 110. For example, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 in accordance with the movement of content displayed on the flexible display 110. For example, when displaying content on the flexible display 110, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 in accordance with shape designation data that designates the shape of the flexible display 110 and is registered as metadata in the content.

[0032] For example, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 in accordance with an instruction from an operator received via the communication unit 150. For example, when a user using the image display device 100 is making a video call via the communication unit 150 with another user using another image display device 100, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 in accordance with an instruction received from the other image display device 100.

[0033] Fig. 2 is an explanatory diagram for explaining deformation of the shape of the flexible display 110. In the example shown in Fig. 2, the flexible display 110 is installed in a housing 122 that can be deformed by a plurality of servo motors 124. The control unit 200 can deform the shape of the flexible display 110 by controlling the rotation and speed of the plurality of servo motors 124.

[0034] Figure 2 illustrates a state in which the cross section of flexible display 110 has a shape that protrudes toward the display surface side (sometimes referred to as a horizontally convex shape) compared to the normal state in which flexible display 110 is not curved and is flat, and a state in which the cross section of flexible display 110 has a shape that recedes toward the display surface side (sometimes referred to as a horizontally concave shape).

[0035] 3 and 4 schematically show an example of use of the image display device 100. The control unit 200 may cause the deformation unit 120 to deform the shape of the flexible display 110 according to the number of people viewing the flexible display 110 recognized by the recognition unit 130.

[0036] As a specific example, if the number of people viewing the flexible display 110 recognized by the recognition unit 130 is less than a predetermined number, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 so that the shape of the flexible display 110 becomes a horizontally convex shape, and if the number is equal to or greater than the predetermined number, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 so that the shape of the flexible display 110 becomes a horizontally convex shape.

[0037] 3 and 4 illustrate a case where the predetermined number is set to 2. As shown in Fig. 3, when the number of people viewing the flexible display 110 is one, by making the flexible display 110 have a horizontally convex shape, it is possible to enhance the sense of immersion and realism that the one person feels when viewing the display content of the flexible display 110. As shown in Fig. 4, when the number of people viewing the flexible display 110 is two, by making the flexible display 110 have a horizontally concave shape, it is possible to make the display content easier to view for each of the two people viewing the flexible display 110 from different positions.

[0038] When the number of people viewing the flexible display 110 recognized by the recognition unit 130 is equal to or greater than a predetermined number, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 so that the shape of the flexible display 110 becomes laterally convex, and the control unit 200 may increase the curvature of the flexible display 110 as the number of people decreases, that is, decrease the curvature of the flexible display 110 as the number of people increases. This makes it easier to view the flexible display 110 in a situation where the flexible display 110 is viewed from more positions.

[0039] The control unit 200 may set the shape of the flexible display 110 to a normal state when the number of people viewing the flexible display 110 recognized by the recognition unit 130 is equal to or greater than a predetermined number, and may cause the deformation unit 120 to deform the shape of the flexible display 110 so that the shape of the flexible display 110 becomes a horizontally convex shape when the number of people viewing the flexible display 110 is less than the predetermined number.

[0040] The control unit 200 may set the shape of the flexible display 110 to a normal state when the number of people viewing the flexible display 110 recognized by the recognition unit 130 is less than a predetermined number, and may cause the deformation unit 120 to deform the shape of the flexible display 110 so that the shape of the flexible display 110 becomes horizontally concave when the number of people viewing the flexible display 110 is equal to or greater than the predetermined number.

[0041] When the number of people viewing the flexible display 110 recognized by the recognition unit 130 is two or more, the control unit 200 may cause the deformation unit 120 to deform the shape of the flexible display 110 so that the cross section of the flexible display 110 has an S-shape. As a specific example, when the number of people viewing the flexible display 110 recognized by the recognition unit 130 is three, and two of the three people are located on the right side as viewed from the flexible display 110 side and one of the three people is located on the left side as viewed from the flexible display 110 side, the control unit 200 may cause the deformation unit 120 to deform the flexible display 110 so that the right side of the flexible display 110 as viewed from the flexible display 110 side is retracted and the left side as viewed from the flexible display 110 side is protruding.

[0042] When there are multiple people viewing the flexible display 110 recognized by the recognition unit 130, the control unit 200 may cause the deformation unit 120 to deform the shape of the flexible display 110 in accordance with the display content displayed on the flexible display 110. For example, when the display content is intended for multiple people, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 so that the shape of the flexible display 110 becomes horizontally concave, and when the display content is intended for a specific person among the multiple people, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 so that the shape of the flexible display 110 becomes horizontally convex, protruding toward the specific person. In this way, when the display content is intended for multiple people, the display form can be made easy to view for all of the multiple people, and when the display content is intended for a specific person among the multiple people, the display form can be made to attract the attention of the specific person.

[0043] The control unit 200 may cause the deformation unit 120 to deform the shape of the flexible display 110 in accordance with the attributes of the person viewing the flexible display 110 recognized by the recognition unit 130 and the display content displayed on the flexible display 110. Examples of the person's attributes include gender, age, and physique (height, weight). For example, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 so that a position on the flexible display 110 corresponding to a person, of the people viewing the flexible display 110, whose attribute corresponds to the display content, protrudes horizontally and convexly. For example, when the attributes of a target person are registered in the display content as metadata, the control unit 200 identifies the position of a person, of the people viewing the flexible display 110, who has an attribute that matches the attribute of a person registered in the display content, and causes the deformation unit 120 to deform the shape of the flexible display 110 so that a position on the flexible display 110 facing the identified position protrudes horizontally and convexly.

[0044] As a specific example, when metadata indicating that the target is a woman is registered in the display content, the control unit 200 identifies the position of the woman among the people viewing the flexible display 110, and causes the deformation unit 120 to deform the shape of the flexible display 110 so that the position of the flexible display 110 facing the identified position becomes a protruding, horizontally convex shape. As a result, for example, when a male-female couple is viewing the flexible display 110 and display content aimed at women is displayed, the flexible display 110 can be shaped so that it protrudes toward the female of the couple, which can increase the attention of the female and create a sense of realism.

[0045] The control unit 200 may cause the deformation unit 120 to deform the shape of the flexible display 110 in accordance with the emotion of the person viewing the flexible display 110 recognized by the recognition unit 130. For example, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 so that, when the shape of the flexible display 110 is deformed into a horizontally convex shape, if the emotion of the person viewing the flexible display 110 is positive, the shape of the flexible display 110 remains horizontally convex, and, when the emotion of the person viewing the flexible display 110 is negative, the shape of the flexible display 110 returns to its normal state. For example, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 so that, when the shape of the flexible display 110 is deformed into a horizontally concave shape, if the emotion of the person viewing the flexible display 110 is positive, the shape of the flexible display 110 remains horizontally concave, and, when the emotion of the person viewing the flexible display 110 is negative, the shape of the flexible display 110 returns to its normal state. As a result, by making the shape of the flexible display 110 horizontally convex or horizontally concave, it is possible to prevent the flexible display 110 from deforming into a horizontally convex or horizontally concave shape for people who may have negative feelings.

[0046] When the display content of the flexible display 110 is a so-called 2D image, the control unit 200 may set the flexible display 110 to a normal state. When the display content of the flexible display 110 is a so-called 3D image, the control unit 200 may cause the deformation unit 120 to deform the shape of the flexible display 110 so that a cross section of the flexible display 110 is L-shaped when the display content of the flexible display 110 is a so-called 3D image. By making the cross section of the flexible display 110 L-shaped, a stereoscopic vision due to an optical illusion can be realized. The control unit 200 may identify the position of a person viewing the flexible display 110 and determine a position at which the flexible display 110 protrudes toward the display surface so that the display content appears stereoscopic when the flexible display 110 is viewed from the identified position. This allows the display content to appear more appropriately stereoscopic from the position of the person actually viewing the flexible display 110.

[0047] When displaying content that flutters in the wind on the flexible display 110, the control unit 200 may cause the deformation unit 120 to dynamically deform the shape of the flexible display 110 so that the flexible display 110 flutters. Examples of content that flutters in the wind include flags and carp streamers. When displaying a flag on the flexible display 110, the control unit 200 may cause the deformation unit 120 to dynamically change the shape of the flexible display 110 so that the flexible display 110 flutters. This allows the viewer to feel as if the flag displayed on the flexible display 110 is actually fluttering.

[0048] When displaying content that flutters in the wind on the flexible display 110, the control unit 200 may cause the deformation unit 120 to dynamically change the shape of the flexible display 110 so that the flexible display 110 flutters, in accordance with the recognition result of the wind around the flexible display 110 by the recognition unit 130. For example, the control unit 200 causes the flexible display 110 to display content that flutters in the wind, and when the strength of the wind around the flexible display 110 is weaker than a predetermined threshold, causes the deformation unit 120 to dynamically deform the shape of the flexible display 110 so that the flexible display 110 flutters, in accordance with the strength of the wind around the flexible display 110. That is, the control unit 200 may cause the deformation unit 120 to dynamically deform the shape of the flexible display 110 so that the stronger the wind around the flexible display 110, the more violently the flexible display 110 flutters.

[0049] Even when content that flutters in the wind is not displayed on the flexible display 110, the control unit 200 may cause the deformation unit 120 to deform the shape of the flexible display 110 in accordance with the recognition result of the wind around the flexible display 110 by the recognition unit 130. For example, when the strength of the wind around the flexible display 110 is weaker than a predetermined threshold, the control unit 200 sets the flexible display 110 to a normal state, and when the strength of the wind around the flexible display 110 is equal to or greater than the threshold, the control unit 200 causes the deformation unit 120 to dynamically deform the shape of the flexible display 110 so that the flexible display 110 flutters. Furthermore, the control unit 200 may cause the deformation unit 120 to dynamically deform the shape of the flexible display 110 in accordance with the strength of the wind around the flexible display 110 so that the flexible display 110 flutters. That is, the control unit 200 may cause the deformation unit 120 to dynamically deform the shape of the flexible display 110 so that the stronger the strength of the wind around the flexible display 110, the more vigorously the flexible display 110 flutters.

[0050] The flexible display 110 may be a touch-sensitive display. When the flexible display 110 is a touch-sensitive display, the control unit 200 may cause the deformation unit 120 to deform the shape of the flexible display 110 so that, when content for touch operation that accepts a touch operation by a user is displayed on the flexible display 110, the display position of the content for touch operation on the flexible display 110 protrudes toward the display surface. This makes it easier for the user to recognize the content to be touched and to touch the content.

[0051] When the recognition unit 130 recognizes that multiple people are viewing the flexible display 110, the control unit 200 may deform the flexible display 110 into a horizontally convex shape and display different display contents on the left and right display surfaces of the flexible display 110, which are divided by the most protruding part of the flexible display 110. This allows display contents intended for a person located on the right side of the flexible display 110 and a person located on the left side of the flexible display 110 to be displayed. In this case, the control unit 200 may control audio output from the multiple directional speakers 140 according to the shape of the flexible display 110. For example, the control unit 200 may control the directional speaker 140 located at a position corresponding to a person located on the right side of the flexible display 110 to output audio intended for the person located on the right side, and the directional speaker 140 located at a position corresponding to a person located on the left side of the flexible display 110 to output audio intended for the person located on the left side. This makes it possible to provide display and audio intended for each of the multiple people.

[0052] 5 is an explanatory diagram for explaining deformation of the shape of the flexible display 110. Here, differences from FIG. 2 will be mainly explained.

[0053] Figure 5 illustrates a state in which the vertical cross section of flexible display 110 has a shape that protrudes toward the display surface side (sometimes referred to as a vertical convex shape) compared to the normal state in which flexible display 110 is not curved, and a state in which the vertical cross section of flexible display 110 has a shape that recedes toward the display surface side (sometimes referred to as a vertical concave shape).

[0054] When the recognition unit 130 recognizes a person whose eye height is higher than the height of the flexible display 110 and a person whose eye height is lower than the height of the flexible display 110, the control unit 200 may cause the deformation unit 120 to deform the shape of the flexible display 110 so that the shape of the flexible display 110 becomes a vertically convex shape or a vertically concave shape.

[0055] As a specific example, when the people viewing the flexible display 110 are a parent and a child, and the parent's eye level is higher than the flexible display 110 and the child's eye level is lower than the flexible display 110, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 so that the shape of the flexible display 110 becomes a vertically convex shape. Then, the control unit 200 may cause content for the parent to be displayed on the upper side of the flexible display 110 and content for the child to be displayed on the lower side. This allows the content to be displayed in a way that is easy for both the parent and the child to see.

[0056] As a specific example, when the people viewing the flexible display 110 are a parent and a child, and the parent's eye level is higher than the flexible display 110 and the child's eye level is lower than the flexible display 110, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 so that the flexible display 110 has a vertically concave shape. Then, the control unit 200 may cause content for the parent to be displayed on the lower side of the flexible display 110 and content for the child to be displayed on the upper side. This allows the content to be displayed in a way that is easy for both the parent and the child to see.

[0057] The image display device 100 may have both the structure shown in Fig. 2 and the structure shown in Fig. 5. In this case, the deformation unit 120 may be able to deform the flexible display 110 into each of a horizontally convex shape, a horizontally concave shape, a vertically convex shape, and a vertically concave shape.

[0058] The deformation unit 120 may deform the flexible display 110 into a shape that protrudes obliquely from the display surface side, or into a shape that retracts obliquely from the display surface side.

[0059] 6 is a schematic diagram illustrating an example of a processing flow by the image display device 100. Here, the processing flow will be described in which the control unit 200 mainly controls the flexible display 110 to change its shape depending on the situation while displaying any display content on the flexible display 110.

[0060] In step (sometimes abbreviated as S) 102, the control unit 200 starts displaying any display content on the flexible display 110. In S104, the recognition unit 130 starts recognizing the situation around the flexible display 110.

[0061] In S106, the control unit 200 determines whether to deform the shape of the flexible display 110. The control unit 200 may determine to deform the shape of the flexible display 110 when either the display content displayed on the flexible display 110 or the situation around the flexible display 110 satisfies a condition for deforming the shape of the flexible display 110. If it is determined to deform the shape of the flexible display 110, the process proceeds to S108.

[0062] In S108, the control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110. The control unit 200 causes the deformation unit 120 to deform the shape of the flexible display 110 according to the condition satisfied in S106.

[0063] In S110, if it is determined that the display on the flexible display 110 should not be ended, the process returns to S106, and if it is determined that the display should be ended, the process ends.

[0064] The image display device 100 is used, for example, for a remote conference. For example, when one participant uses one image display device 100 to participate in a remote conference, the control unit 200 may cause the flexible display 110 to have a horizontally convex shape or to be in a normal state. When multiple participants use one image display device 100 to participate in a remote conference, the control unit 200 may cause the flexible display 110 to have a horizontally concave shape when the display content is intended for all participants, and may cause the flexible display 110 to have a horizontally convex shape when the display content is intended for a specific participant, so that a position on the flexible display 110 corresponding to the specific participant protrudes toward the display surface.

[0065] The image display device 100 is used, for example, for digital advertising. The image display device 100 may be placed in a taxi or a toilet, or in a station, a store, a facility, an office, or the like. The image display device 100 displays advertising content on the flexible display 110 in accordance with shape designation data registered as metadata in the advertising content by an advertiser, while causing the deformation unit 120 to deform the shape of the flexible display 110. Furthermore, for example, the flexible display 110 can be used to display three-dimensional (3D) advertising content that utilizes an optical illusion by bending it into an L-shape, and an optimal shape can be adopted for each of the 2D and 3D advertising content. These can contribute to improving the persuasiveness and appeal of the advertising content.

[0066] The image display device 100 is used, for example, for online customer service. The image display device 100 may serve customers using, for example, an avatar displayed on the flexible display 110. The image display device 100 may be used for customer service in, for example, izakayas, department stores, convenience stores, restaurants, etc. The image display device 100 may be used for viewing services in, for example, museums, art galleries, aquariums, etc. The image display device 100 may be used for concierge services in, for example, department stores, city halls, hospitals, etc. For example, the control unit 200 serves customers using the avatar displayed on the flexible display 110, while causing the deformation unit 120 to deform the shape of the flexible display 110 in response to changes in the surrounding situation, changes in the emotions of the person being served, etc.

[0067] 7 schematically shows an example of the hardware configuration of a computer 1200 functioning as the image display device 100 or the control unit 200. A program installed on the computer 1200 can cause the computer 1200 to function as one or more "units" of the device according to the present embodiment, or can cause the computer 1200 to perform operations associated with the device according to the present embodiment or one or more "units," and / or can cause the computer 1200 to perform a process according to the present embodiment or steps of the process. Such a program can be executed by the CPU 1212 to cause the computer 1200 to perform specific operations associated with some or all of the blocks in the flowcharts and block diagrams described herein.

[0068] The computer 1200 according to this embodiment includes a CPU 1212, a RAM 1214, and a graphics controller 1216, which are interconnected by a host controller 1210. The computer 1200 also includes input / output units such as a communications interface 1222, a storage device 1224, a DVD drive, and an IC card drive, which are connected to the host controller 1210 via an input / output controller 1220. The DVD drive may be a DVD-ROM drive, a DVD-RAM drive, or the like. The storage device 1224 may be a hard disk drive, a solid-state drive, or the like. The computer 1200 also includes a ROM 1230 and legacy input / output units such as a keyboard, which are connected to the input / output controller 1220 via an input / output chip 1240.

[0069] The CPU 1212 operates according to programs stored in the ROM 1230 and the RAM 1214, thereby controlling each unit. The graphics controller 1216 acquires image data generated by the CPU 1212 into a frame buffer or the like provided in the RAM 1214 or into the graphics controller 1216 itself, and causes the image data to be displayed on the flexible display 110.

[0070] The communication interface 1222 communicates with other electronic devices via a network. The storage device 1224 stores programs and data used by the CPU 1212 in the computer 1200. The DVD drive reads programs or data from a DVD-ROM or the like and provides them to the storage device 1224. The IC card drive reads programs and data from an IC card and / or writes programs and data to an IC card.

[0071] The ROM 1230 stores therein a boot program or the like that is executed by the computer 1200 upon activation, and / or programs that depend on the hardware of the computer 1200. The input / output chip 1240 may also connect various input / output units to the input / output controller 1220 via a USB port, a parallel port, a serial port, a keyboard port, a mouse port, etc.

[0072] The programs are provided by a computer-readable storage medium such as a DVD-ROM or an IC card. The programs are read from the computer-readable storage medium, installed in the storage device 1224, RAM 1214, or ROM 1230, which are also examples of computer-readable storage media, and executed by the CPU 1212. Information processing described in these programs is read by the computer 1200, and causes cooperation between the programs and the various types of hardware resources described above. An apparatus or method may be configured by implementing operations or processing of information in accordance with the use of the computer 1200.

[0073] For example, when communication is performed between the computer 1200 and an external device, the CPU 1212 may execute a communication program loaded into the RAM 1214 and instruct the communication interface 1222 to perform communication processing based on the processing described in the communication program. Under the control of the CPU 1212, the communication interface 1222 reads transmission data stored in a transmission buffer area provided in the RAM 1214, the storage device 1224, a DVD-ROM, or a recording medium such as an IC card, and transmits the read transmission data to the network, or writes reception data received from the network to a reception buffer area or the like provided on the recording medium.

[0074] Furthermore, the CPU 1212 may cause all or a necessary portion of a file or database stored in an external recording medium such as the storage device 1224, a DVD drive (DVD-ROM), an IC card, etc. to be read into the RAM 1214, and may perform various types of processing on the data on the RAM 1214. The CPU 1212 may then write back the processed data to the external recording medium.

[0075] Various types of information, such as various types of programs, data, tables, and databases, may be stored on the recording medium and may undergo information processing. The CPU 1212 may perform various types of processing on data read from the RAM 1214, including various types of operations, information processing, conditional judgment, conditional branching, unconditional branching, information search / replacement, etc., as described throughout this disclosure and specified by the instruction sequences of the programs, and write the results back to the RAM 1214. The CPU 1212 may also search for information in a file, database, etc. on the recording medium. For example, if multiple entries, each having an attribute value of a first attribute associated with an attribute value of a second attribute, are stored on the recording medium, the CPU 1212 may search for an entry whose attribute value of the first attribute matches a specified condition from among the multiple entries, read the attribute value of the second attribute stored in the entry, and thereby obtain the attribute value of the second attribute associated with the first attribute that satisfies a predetermined condition.

[0076] The above-described programs or software modules may be stored in a computer-readable storage medium on or near the computer 1200. A recording medium such as a hard disk or RAM provided in a server system connected to a dedicated communication network or the Internet can also be used as a computer-readable storage medium, thereby providing the programs to the computer 1200 via the network.
