[0090] The first position information input unit 140_11 may be driven integrally with another position information input unit, or may be driven separately. The driving circuits may be driven individually.

[0091] For example, the power consumed by the first position information input unit 140_11 and the power consumed by the second position information input unit The sum of the power consumed by the first position information input unit 140_12 is the power consumed by the first position information input unit 140_11. If the force is greater than the force, the first position information input unit 14 Alternatively, only the first position information input unit 0_11 may be driven, and the driving of the second position information input unit may be stopped. By stopping the driving of the information input unit 140_12, the power consumption can be reduced. .

The material can be used for the housing.

[0111] Note that this embodiment mode can be appropriately combined with other embodiment modes described in this specification. .

[0112] (Embodiment 3) In this embodiment, the configuration of a program applicable to the information processing device 100 will be described with reference to FIG. 6. Here, the information processing device 100 shown in FIG. Thus, the first region 131_11, the second region 131_12, the third region 131_13, The first bendable region 131_21 and the second bendable region 131_22 are provided. It shall be so.

[0113] FIG. 5 is a flow diagram for explaining a program executed by the arithmetic unit of the information processing device. FIG. 6 is a flow diagram illustrating an interrupt process of the program described with reference to FIG. 5.

[0114] <Configuration example of information processing device> The information processing device 100 described in this embodiment includes a calculation unit 111 and an execution unit 112. The device further includes a storage unit 112 for storing a program for causing the device to

[0115] The program stored in the storage unit 112 includes the following steps.

[0116] [First step] In the first step, initial information including status information is obtained (FIG. 5(S1)).

[0117] For example, the predetermined status information stored in the storage unit 112 and the The initial information includes information necessary for detecting the detection result. It may include information S.

[0118] Specifically, the display unit 130 displays the detection information S supplied by the detection unit 150 as shown in FIG. If it contains information indicating a collapsed state, it is the first status, and indicates an expanded state. If the status information is included, the status information to be used as the second status is obtained. For simplicity, we consider only the above two statuses. For example, Figure 1(C) Flows that adapt to folded states or other folding methods can be constructed in a similar manner.

[0119] [Second step] In the second step, interrupt processing is permitted (FIG. 5 (S2)). The arithmetic unit 111 that is permitted to process an interrupt can receive an execution command for the interrupt process. When the processor 111 receives an instruction to execute an interrupt process, it suspends the main process and executes the interrupt process. The interrupt process is then executed, and the execution result of the interrupt process is stored in, for example, a storage unit. The arithmetic unit that returns to the main processing from the interrupt processing performs the following operations based on the execution result of the stored interrupt processing. The main processing can then be resumed.

[0120] [Third step] In the third step, predetermined information is acquired (FIG. 5(S3)).

[0121] The predetermined information may be used as a basis for generating a first image, a second image, or a third image in a later step. Here, the first image includes information that becomes the first region 131_11, the second region 131 _12, the third region 131_13, the first bendable region 131_21, the second bendable region The first image is an image having a size optimized for display in the area 131_22. The image is an image of a size optimized for display in only the first region 131_11. The third image is an image displayed in the first area 131_11 and the second area 131_12. In particular, the image displayed in the second region 131_12 is transmitted through the first region 131_11. The first area 131_11 and the second area 131_12 are displayed. The image is sized to be optimized for

[0122] If you proceed from step 9 to step 3, which will be explained later, The operation command or updated status information provided by the interrupt is reflected in the do.

[0123] [Fourth step] In the fourth step, if the status information is the first status, the sixth step If the status is the second one, the process proceeds to the fifth step (FIG. 5 (S4)).

[0124] [5th ​​step] In a fifth step, a first image is displayed based on the information obtained in the third step. In other words, the first image is displayed in the first region. The first bendable region 131_11, the second region 131_12, the third region 131_13, The region 131_21 is displayed in a second bendable region 131_22 (first display).

[0125] [Sixth step] If you do not want to display the transparent image in the sixth step, proceed to the seventh step and select the transparent image. If display is to be performed, the process proceeds to the eighth step (FIG. 5 (S6)).

[0126] [Seventh step] Based on the information obtained in the third step, the second image is determined to fit into the first region 131_11. Then, the image information V is generated so as to be displayed (FIG. 5(S7)). The image is displayed only in the first area 131_11 (second display).

[0127] For example, based on the information obtained in the third step, the image is arranged to fit into the first region 131_11. Then, image information V is generated that displays an image whose area has been adjusted as described above.

[0128] For example, if information including numbers or letters is acquired in the third step and the display unit 130 is folded When the folded state is detected, the first area 131_11 is made landscape so that it can be read easily. Image information V is generated which displays a first image in which numbers or letters are arranged.

[0129] For example, based on the information obtained in the third step, the image is enlarged so that it fits within the display area of ​​the display. Image information V representing the size-adjusted image is generated.

[0130] For example, if information including numbers or letters is acquired in the third step and the display unit 130 is When the display unit 130 detects a state where the number or alphabet is displayed, the display unit 130 is rotated to a landscape orientation so that the number or alphabet can be displayed in a suitable manner. Image information V is generated which displays a second image in which characters are arranged.

[0131] [8th step] Based on the information obtained in the 3rd step, a screen displaying a 3rd image is generated. In other words, the third image is stored in the first area 13. 1_11 and the second area 131_12 (third display). The display of 1_12 can be seen through the first region 131_11. However, in this case, The display in the second area 131_12 is viewed from the opposite side to the first display. If the image is displayed in the same manner as the first display, it will be viewed as being inverted horizontally or vertically. Therefore, in the third display, the display of the second area 131_12 is The display in the second region 131_12 is a first display formed in the first bendable region 131_21. It is assumed that the fold of is flipped around the axis.

[0132] [9th step] In the seventh step, if the end command is provided in the interrupt process, the tenth step If the supply is not made, the process proceeds to the third step (FIG. 5 (S9)).

[0133] [10th step] In the tenth step, the process ends (FIG. 5 (S10)).

[0134] In the above example, there is only one collapsed state, but for example, in the first part of the above program, In step 5, for example, the first bendable region 131_21 is folded in two. If a different status (a status different from the first status) is detected, the second image is transferred to the first image. The image information V is generated so as to fit in an area other than the area 131_11, and the first area 131_1 A second image may be displayed in an area other than the first image (FIG. 3(C)). The ratio of the horizontal length D to the vertical length D (E:D) is approximately 3:4 or close to that ratio. It can be displayed.

[0135] In addition, the second image may be arranged above or below the area other than the first area to make the second image appear as a first image. Image information V may be generated so as to fit into an area other than area 1.

[0136] In addition to software keyboards, characters, and photographic images, images broadcast on television, etc. It can be included in the second image.

[0137] [Interrupt processing] Moreover, the interrupt process includes the following steps.

[0138] [11th step] In an eleventh step, the detection information S is acquired (FIG. 6 (T11)).

[0139] For example, the detection information S supplied by the detection unit 150 is acquired using a timer or the like. and detecting information S including information indicating whether the display unit 130 is in a folded or unfolded state. Get it.

[0140] [12th step] In the 12th step, candidate information is determined based on the detection information S (FIG. 6 (T12)). .

[0141] [13th step] In the thirteenth step, if the candidate information is different from the status information, the fourteenth step If they are the same, proceed to step 11 (FIG. 6 (T13)).

[0142] [14th step] In the fourteenth step, the status information is updated to the candidate information (FIG. 6 (T14)).

[0143] For example, if there is a change in the detection information S, the status information is updated. If there is a change in the information indicating whether the unit 130 is in a folded or unfolded state, the stator Update the service information.

[0144] [15th step] In the fifteenth step, the process returns from the interrupt process (FIG. 6 (T15)).

[0145] In the interrupt process, the updated status information is The result is reflected after the step is started. Also, in the interrupt process, the end command is issued. If so, proceed to step 10 and exit.

[0146] The information processing device 100 described in this embodiment has a display unit in a folded or unfolded state. A step of acquiring detection information S including information indicating whether the state is a candidate state, and determining candidate information; if the status information is different from the candidate information, updating the status information to the candidate information; and generating and displaying image information V including predetermined information based on the updated status information. This includes the steps of: The image can be displayed in a set area based on the size of the image. This makes it possible to provide a novel information processing device with excellent reliability.

[0147] <Program variation 1.> In the first modification, a modification of a program applicable to an information processing device will be described.

[0148] Modification 1 is the fifth, seventh, and eighth steps of the above program. and generate image information V that displays a fourth image outside the first image or the second image. The differences are explained here, and similar steps can be used. The above explanation applies to the parts that can be displayed. In this example, This will not be mentioned here, but it can be implemented in the same way.

[0149] [5th ​​step] In a fifth step, based on the information obtained in the third step, the first region 131 _11, the second region 131_12, the third region 131_13, the first bendable region 13 1_21, a first image is displayed so as to fit into a second bendable area 131_22, and the first Image information V that displays a fourth image outside the area displaying the first image is generated and displayed.

[0150] [Seventh step] In a seventh step, based on the information obtained in the third step, the first region 131 Display the second image so that it fits in _11, and display the fourth image outside the area where the second image is displayed. Image information V representing the image is generated and displayed.

[0151] This allows the fourth image to be displayed outside the area in which the first image or the second image is displayed. As a result, a novel information processing device with excellent convenience and reliability can be provided. For example, the fourth image may be displayed when there is a specific status or instruction. It may be arranged not to be displayed.

[0152] For example, a fourth image including text information may be displayed outside the first or second image. Image information V may be generated and displayed. Specifically, in the first bendable region 131_21, A fourth image may be displayed (see FIG. 3(B)).

[0153] A fourth image may be displayed, which moves in a flowing manner. Also, based on the rules of the language in which it is displayed, The direction of movement of the characters in the fourth image may be changed by changing the direction of movement of the characters in the fourth image. For example, English is written from right to left. The speed of the text can be moved from left to right for Arabic text, or from right to left for Arabic text. The setting may be made according to the above.

[0154] Furthermore, text information or the like may be superimposed on the first image or the second image.

[0155] The fourth image can also include a phone number, temperature, the contents of an incoming email, etc.

[0156] <Program variation 2.> In the second modification, a modification of a program applicable to an information processing device will be described.

[0157] In the information processing device 100 to which the program described in the second modification can be applied, the detection unit 150 detects a display The posture of the display unit 130 is detected, and detection information S including information indicating the detected posture is supplied. .

As a result, a new type of display that is highly convenient and reliable can be displayed on the display unit. It is possible to provide a new information processing device.

[0160] For example, when the display unit 130 is folded and the first area is detected to be vertically long, Or, when the display unit is unfolded and detects that the display unit is in a portrait orientation, the fourth image The characters displayed in may be written vertically.

[0161] The second modification has a detection unit 150 that can detect the orientation of the display unit 130. In the first step of the program, the display unit 130 is folded or unfolded. Obtain status information by combining information indicating the state of the display unit 130 with information indicating the position of the display unit 130 Then, in the fifth, seventh or eighth step, information indicating the posture is The first image to the third image and the display orientation are determined based on the combined status information. and generating image information V that displays the first image to the third image in the determined orientation. In an eleventh step, the display unit 130 is displayed in a folded or unfolded state. The detection information S including not only the information indicating the position of the display unit 130 but also the position of the display unit 130 is obtained. In addition to the information on whether the device is folded or unfolded, the display also shows the appearance of the device. The difference here is that when there is a change in the information showing the trend, the status information is updated.

[0163] A sensor for detecting the orientation of the display unit 130 is disposed on the housing, for example.

[0164] [Modification of the first step] In the first step, initial information including status information is obtained. The information indicating that the unit 130 is folded is included in the detection information S supplied by the detection unit 150. If the information includes information indicating an expanded state, the status is considered to be primary. Furthermore, the display unit 130 is in a horizontal position. By adding information about whether the status is long or vertical, a total of four types of expanded Status information is defined and used.

Image information V that displays a first image so as to fit into the second bendable region 131_22 and displays the image information V.

[0166] For example, the display can be rotated horizontally or vertically based on the status information obtained in the third step. Generate image information V that displays an image whose orientation and size are adjusted to fit within the display area of ​​the Complete.

[0167] [Modification of the seventh step] In the seventh step, the folded state and the display state of the display unit obtained in the third step are Based on the status information indicating the posture of the display unit, the first region 131_11 is adjusted to fit within the first region 131_11. The image information V representing the image of the second pixel is generated, and the image information V is displayed. A similar transformation is performed for the eighth pixel. This is also done at the step.

[0168] For example, the first one, landscape or portrait, is selected based on the status information obtained in the third step. Image information showing an image whose orientation and size are adjusted to fit within the area 131_11 Generate V.

[0169] [Modification of the 11th step] In an eleventh step, detection information S including information indicating the attitude of the display unit is acquired.
