[0110] [Case] In order to protect the arithmetic unit 110 and the like from various stresses applied to the information processing device 100, The information processing device 100 may have a housing made of a transparent material such as plastic or glass. The material can be used for the housing.

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

[0112] (Embodiment 3) In this embodiment, the configuration of a program applicable to the information processing device 100 is shown in FIG. 6. Here, the information processing device 100 is a 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. Let's say.

[0113] FIG. 5 is a flow diagram illustrating a program executed by the arithmetic unit of the information processing device. FIG. 6 is a flow chart 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 a program executed by the calculation unit 111. The device includes a storage unit 112 that stores a program for causing the device to perform the operation.

[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 acquired (FIG. 5(S1)).

[0117] For example, predetermined status information stored in the storage unit 112 and used in later steps The initial information includes the information necessary for detecting the detection target. It may contain 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 it indicates an expanded state. If the information is included, the status information to be used as the second status is acquired. 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 also be constructed in the same way.

[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 arithmetic unit 111 receives an instruction to execute an interrupt process, it suspends the main process and executes the interrupt process. The execution result of the interrupt process is stored in, for example, a storage unit. The calculation unit that returns to the main processing from the interrupt processing executes the stored interrupt processing result. 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 is the basis for generating a first image, a second image, or a third image in a later step. Here, the first image includes information such as a first region 131_11, a second region 131_21, and a _12, the third region 131_13, the first bendable region 131_21, the second bendable region 131_22, The first image is an image of a size optimized for display in the area 131_22. The image is of a size optimized for display in only the first area 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 area 131_12 is transmitted through the first area 131_11. The image is displayed in a first area 131_11 and a second area 131_12. It is an image with a size 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 process is reflected in the do.

[0123] [Fourth step] In the fourth step, if the status information is the first status, proceed to the sixth step. If the status is the second, 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 region 131_11, the second region 131_12, the third region 131_13, and the first bendable region 131_14 are The first bendable area 131_21 is displayed in the second bendable area 131_22 (first display).

[0125] [Sixth step] If you do not want to display transparently in the sixth step, proceed to the seventh step. 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. 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. Image information V is generated that displays an image whose area has been adjusted as described above.

[0128] For example, if the third step acquires information including numbers or letters and the display unit 130 is folded, When the folded state is detected, the first area 131_11 is made landscape-oriented so that it can be read easily. Image information V is generated that 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 to fit within the display area of ​​the display. Image information V representing the image with the adjusted size is generated.

[0130] For example, if information including numbers or letters is acquired in the third step and the display unit 130 When the state where the key is pressed is detected, the display unit 130 is turned horizontally to display numbers or letters so that they can be easily read. Image information V is generated that displays a second image in which characters are arranged.

[0131] [8th step] Based on the information obtained in the 3rd step, a screen displaying the 3rd image is generated. The image information V is generated and displayed (FIG. 5(S8)). That is, the third image is displayed 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. The display in the second area 131_12 is viewed from the opposite side to the first display. When displayed in the same manner as the first display, the image is 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 formed in the first bendable region 131_21. The fold of is flipped around the axis.

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

[0133] [Step 10] 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 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 The image information V is generated so as to fit into an area other than the area 131_11, and the first area 131_1 The 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. It can be displayed.

[0135] In addition, the second image may be arranged above or below the area other than the first area, and the second image may be arranged above or below the first area. 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] The interrupt process also includes the following steps:

[0138] [Step 11] In the 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 the detection information S including information indicating whether the display unit 130 is in a folded state or an unfolded state is Get it.

[0140] [12th Step] In the twelfth 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] [Step 14] 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] [Step 15] 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 change is reflected after the step is completed. Also, in the interrupt processing, If so, proceed to step 10 and exit.

[0146] The information processing device 100 described in this embodiment has a display unit that is folded or unfolded. A step of acquiring detection information S including information indicating whether the state is in a state where the sensor ... 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. and a step of: This allows an image of a size based on the user's preference to be displayed in a set area. This makes it possible to provide a novel information processing device with excellent reliability.

[0150] [Seventh step] In a seventh step, based on the information obtained in the third step, the first region 131 The second image is displayed so that it fits in the area of ​​_11, and the fourth image is displayed 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 where the first or 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 possible to have it not be displayed.

[0152] For example, an image that displays a fourth image containing text information outside the first or second image may be used. 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 smoothly. For example, English is written from right to left. The speed of the movement can be adjusted depending on the user's preference. It may be possible to set it 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.
