Further, the second image is an image having a design different from that of the first image, and has a pattern that becomes an accent of the standby image when combined with the first image.

  As shown in FIG. 6, the design of the first image is a plant such as an ivy. The first images PX1, PX2, PX3, and PX4 shown in FIG. 5 are ivy images, but have different designs. The first candidate groups YA1 to YA4 belonging to the second image candidate group Y are the second images PYB1 to PYB8 belonging to the second candidate group YB1 to YB4 and the second images PYC1 to PYC9 belonging to the third candidate group YC1 to YC4. It is a collection of different second images PYA1 to PYA16. The second candidate groups YB1 to YB4 are a group of second images PYB1 to PYB8 different from the second images PYC1 to PYC9 belonging to the third candidate group YC1 to YC4.

  The first image candidate group X is configured by collecting a plurality of first image candidates. In the present embodiment, the four first images PX1, PX2, PX3, and PX4 belong to the first image candidate group X as candidates for the first image selected as the standby image. Each of the second image candidate groups Y1, Y2, Y3, and Y4 is configured by collecting a plurality of second image candidates. In the present embodiment, the second image candidate group Y1 includes a total of three second image candidate groups, a first candidate group YA1, a second candidate group YB1, and a third candidate group YC1. Similarly to the second image candidate group Y1, the second image candidate groups Y2, Y3, Y4 are sequentially in turn, the first candidate groups YA2, YA3, YA4, the second candidate groups YB2, YB3, YB4, and the third candidate group YC2. , YC3, and YC4, a total of three second image candidate groups. Note that each of the first candidate groups YA1 to YA4, the second candidate groups YB1 to YB4, and the third candidate groups YC1 to YC3 is a collection of a plurality of second image candidates.

  As can be seen from FIG. 5, in the present embodiment, the first candidate group YA1 includes the second images PYA1 to PYA4, the first candidate group YA2 includes the second images PYA5 to PYA8, and the first candidate group YA3. The second images PYA9 to PYA12 belong, and the second images PYA13 to PYA16 belong to the second candidate group YA4. The second candidate group YB1 includes the second image PYB1, the second candidate group YB2 includes the second images PYB2 and PYB3, the second candidate group YB3 includes the second images PYB4 to PYB6, and the second candidate group YB4. Includes second images PYB7 and PYB8. Further, the first images PYC1 to PYC3 belong to the third candidate group YC1, the second images PYV4 to PYC9 belong to the third candidate group YC2, and the second images PYC1 to PYC6, PYC8, PYC9 belongs, and second images PYC1 to PYC8 belong to the third candidate group YC4. Thus, a total of 16 types of second images belong to the first candidate group YA1 to YA4, a total of 8 types of second images belong to the second candidate group YB1 to YB4, and belong to the third candidate groups YC1 to YC4. A total of nine types of second images belong. That is, a total of 33 types of second images belong to the second image candidate group Y1 to Y4.

  The second images PYA1 to PYA16 belonging to the first candidate group YA1 to YA4 are images of animals such as deer and cats, for example. In addition, the second images PYB1 to PYB8 belonging to the second candidate group YB1 to YB4 are, for example, wing-like images. In addition, the second images PYC1 to PYC9 belonging to the third candidate group YC1 to YC4 are, for example, images with a pattern like a flower. In the present embodiment, each of the first image and the second image is a single color image. Accordingly, the data amount of the first image and the second image can be reduced as compared with the case where the first image and the second image are configured with a plurality of colors.

  The second image combined with each of the first images PX1, PX2, PX3, and PX4 is such that the image obtained by combining the first image and the second image is not unnatural and creates a sense of unity in design. The correct image is selected. In this way, the collection of second images selected for each of the first images PX1, PX2, PX3, and PX4 is the second image candidate group Y1, Y2, Y3, and Y4 in FIG. In the present embodiment, since there are four types of first images, four second image candidate groups Y1, Y2, Y3, and Y4 are prepared. Accordingly, as shown in FIG. 5, the plurality of second image candidate groups Y1, Y2, Y3, Y4 correspond to the plurality of first images PX1, PX2, PX3, PX4 belonging to the first image candidate group X, respectively. Attached.

  For example, as shown in FIG. 5, the second image candidate group Y1 corresponds to the first image PX1. The second image candidate group Y1 corresponding to the first image PX1 includes the first candidate group YA1, the second candidate group YB1, and the third candidate group YC1. The plurality of second images belonging to the first candidate group YA1, the second candidate group YB1, and the third candidate group YC1 are not unnatural when combined with the first image PX1 and have a sense of unity in design. It is an image that is born.

  A second image that has unnaturalness or a sense of unity when combined with a certain first image is not combined with the first image in the first place. That is, such a second image is not used as a standby image in relation to the first image. In the present embodiment, a second image candidate group in which a plurality of second images that are not unnatural when combined with the first image and have a sense of unity is collected is assigned to each of the plurality of first image candidate groups. Prepare in advance. Thereby, the second image that is not combined with the first image, that is, not used as the standby image in the relationship with the specific first image, can be excluded in advance in combination with the specific first image. As a result, since the second image that cannot be combined with the corresponding first image can be excluded from each second image candidate group, there is no need to save the unnecessary second image in the storage unit 13. Data capacity can be reduced.

  In the present embodiment, the first image is a pattern that directs the entire standby image, and the number of pixels (at least the number of pixels when converted to a bitmap) is an image that is larger than the second image. . For this reason, if there are many types of the first image, the storage unit 13 needs a large capacity to store the first image. In some cases, the image data allocated in the storage unit 13 is not stored. There is a risk of exceeding the capacity of the image data storage unit 13f to be stored. For this reason, the type of the first image is made smaller than the type of the second image so that the first image candidate group X can be stored in the image data storage unit 13f. In the present embodiment, as described above, four types of first images and 33 types of second images are prepared and stored in the image data storage unit 13f of the storage unit 13, so the type of the first image is that of the second image. About 1/8 of the kind.

  In this embodiment, when a standby image to be displayed on the display unit 17 of the mobile electronic device 1 is generated, first, one first image is selected from the plurality of first images PX1 to PX4 belonging to the first image candidate group X. Is done. Then, a second image candidate group corresponding to the selected first image can be selected from the plurality of second image candidate groups Y1 to Y4. At least one second image is further selected from the second image candidate group. In the present embodiment, among the second image candidate groups corresponding to the selected first image, two from one of the first candidate group or the second candidate group and one from the third candidate group. Two second images are selected.

  For example, as shown in FIG. 5, it is assumed that the first image PX1 is selected from four types of first images PX1 to PX4 belonging to the first image candidate group X. Since the second image candidate group Y1 corresponds to the first image PX1, two second images are selected from the second image candidate group Y1. In this case, one of four types of second images PYA1 to PYA4 belonging to the first candidate group YA1 or one type of second image PYB1 belonging to the second candidate group YB1 (for example, from the first candidate group YA1). The second image PYA1) and one of the three types of second images PYC1 to PYC3 belonging to the third candidate group YC1 (for example, the second image PYC1) are selected in total. Then, one image configured by combining the selected first image PX1, second image PYA1, and second image PYC1 is displayed on the display unit 17 of the portable electronic device 1 as a standby image.

  As described above, the second image candidate group corresponding to the first image PX1 is the second image candidate group Y1. The second image candidate group Y1 includes a first candidate group YA1 to which four types of second images PYA1 to PYA4 belong, a second candidate group YB1 to which one type of second image PYB1 belongs, and three types of second images PYC1 to PYC1. It is composed of a third candidate group YC1 to which PYC3 belongs. Since the second image is selected from either the first candidate group YA1 or the second candidate group YB1, there are five options in this selection. Further, since one third image is selected from the third candidate group YC1, there are three options for this selection. Therefore, when the first image PX1 is selected, in the second image candidate group Y1 corresponding thereto, a total of 15 combinations of 5 × 3 are obtained.

  For this reason, 15 images can be generated when the first image PX1 is selected. Similarly, 36 images can be generated when the first image PX2 is selected, 56 images can be generated when the first image PX3 is selected, and 48 images can be generated when the first image PX4 is selected. Therefore, in the present embodiment, a total of 155 patterns of 15 patterns + 36 patterns + 56 patterns + 48 patterns are selected from 37 types of images including four types of first images and 33 types of second images stored in the image data storage unit 13f. A standby image can be generated.

  As described above, in the present embodiment, when the second image candidate group, which is a collection of the plurality of second images, is associated with each of the plurality of first images, when the second image candidate group is combined with the specific first image, The second image having unnaturalness or a sense of unity is excluded in advance in combination with the first image. This eliminates useless images and realizes a reduction in the volume of image data. When generating a standby image, one first image is selected from the first image candidate group by lottery or the like, and at least one second image is selected from the second image candidate group corresponding to the selected first image. An image is selected by lottery or the like, and a standby image is generated by combining the selected first image and second image.

  By such a method, in the image generation method according to the present embodiment, the first image data and the second image data stored in the image data storage unit 13f can be reduced in capacity, and various standby images with changes can be obtained. Can be generated. Furthermore, in the image generation method according to the present embodiment, the first image and the second image are monochromatic images, so that the combined images are naturally combined, and further reduction in the volume of image data is realized.

  As described above, in the present embodiment, the first image and the second image having a small capacity corresponding to the elements of the standby image displayed on the display unit 17 may be stored in the plurality of storage units 13. As a result, it is possible to display various varied images with a small amount of image data compared to a case where a plurality of irrelevant image data is randomly displayed on the display unit 17. Next, a procedure for generating a standby image using the image generation method of the present embodiment and displaying it on the display unit 17 of the portable electronic device 1 when a predetermined event occurs in the portable electronic device 1 will be described.

  FIG. 7 is a flowchart illustrating an example of processing for displaying a standby image generated by the image generation method of the present embodiment. FIG. 8 is a flowchart showing a procedure for generating a standby image by the image generation method of the present embodiment. FIG. 9 is a flowchart showing another example of processing for displaying a standby image generated by the image generation method of the present embodiment. The standby image is displayed on the display unit 17 of the portable electronic device 1 when a predetermined event occurs.

  The predetermined event is, for example, a state in which the portable electronic device 1 is waiting for reception of an incoming call from the network side, that is, when a standby state occurs. For example, the image display processing unit 12c of the processing unit 12 illustrated in FIG. 4 detects whether the casing 1C of the portable electronic device 1 is in the open state or the closed state is released. When the part 12b detects, it is judged that the portable electronic device 1 is in a standby state. Then, in the standby state, the processing unit 12 causes the display unit 17 of the mobile electronic device 1 to display a standby image. When the portable electronic device 1 is not in a standby state (step S101: No), a standby image is not displayed.

  When the portable electronic device 1 is in a standby state (step S101: Yes), a standby image can be displayed on the display unit 17. In this case, the main processing unit 12a transfers control to the image display processing unit 12c. That is, the main processing unit 12a allocates the hardware resources of the processing unit 12 and the storage unit 13 to the standby image display task 13b. Thereby, the image display processing unit 12c executes the standby image generation task 13a, and generates a standby image by the image generation method according to the present embodiment (step S102). This procedure will be described with reference to FIG.

  The image display processing unit 12c executes the standby image generation task 13a, and draws first images from a plurality of first images belonging to the first image candidate group X stored in the image data storage unit 13f of the storage unit 13. (Step S201), and is selected as the first image constituting the standby image. Next, the image display processing unit 12c determines whether or not to draw a second image from a plurality of second images belonging to the second candidate group constituting the second image candidate group (step S202). For example, when the second image is drawn from the second candidate group at a rate of once every predetermined number of times (for example, 10 times), and the second image is drawn a predetermined number of times from the first candidate group, You may determine to draw a 2nd image from a 2nd candidate group.

  When the second image is not selected from the second candidate group (step S202: No), the image display processing unit 12c selects the second image from the first candidate group (step S203), and configures the second image that forms the standby image. Select as one of the images. When the second image is selected from the second candidate group of the second image candidate group (step S202: Yes), the image display processing unit 12c selects the second image from the second candidate group (step S204) and waits. This is selected as one of the second images constituting the image. Next, when one second image is selected, the image display processing unit 12c extracts one second image from the third candidate group of the second image candidate group (step S205), and configures a standby image. Select as one of two images.

  When one first image and two second images are selected by the above procedure, the image display processing unit 12c requests the file system control unit 12f to select the selected first image and second image. Issue. Then, the file system control unit 12f executes the file system control task 13e, and selects one first image and two second images selected by the above procedure from the image data storage unit 13f of the storage unit 13. . When one first image and two second images are selected, the file system control task 13e ends. When the file system control task 13e is finished, the file system control unit 12f issues a completion notification to the image display processing unit 12c. The image display processing unit 12c reads and combines one first image data file and two second image data files selected by the file system control unit 12f from the image data storage unit 13f (step S206). A standby image is generated. When the standby image is generated, the image display processing unit 12c temporarily stores the generated standby image in a storage area secured as a work area of the storage unit 13, and ends the standby image generation task 13a.

  Next, referring back to FIG. When the image display processing unit 12c generates a standby image, the image display processing unit 12c executes the standby image display task 13b and issues a decoding processing request to the decoding processing unit 12d. The decode processing unit 12d executes the decode task 13c, and reads out the standby image generated in step S102 and stored in the work area of the storage unit 13 from the work area. Then, the decode processing unit 12d decodes the read standby image and converts it into bitmap data expressed in RGB (step S103). When the decoding is completed, the decoding processing unit 12d issues a completion notification to the image display processing unit 12c. Then, the image display processing unit 12c issues a standby image display request to the display control unit 12e. The display control unit 12e executes the display control task 13d to display a standby image of a bitmapped pattern on the display unit 17, more specifically on the main display 2M (step S104). Thereafter, the display control unit 12e issues a completion notification to the image display processing unit 12c, and the display of the standby image is completed.

  Next, a process for displaying the standby image shown in FIG. 9 will be described. In this process, when the processing load on the processing unit 12 is reduced, for example, a standby image is generated in advance during the idle time of the processing unit 12 and stored in the image data storage unit 13f, and a predetermined event occurs. Sometimes, the created standby image is displayed on the display unit 17 of the portable electronic device 1. As a result, when the above-described predetermined event occurs, the standby image is promptly displayed on the display unit 17, so that the responsiveness from when the predetermined event occurs until the standby image is displayed is improved. .

  First, the image display processing unit 12c determines whether or not a free time has occurred in the processing unit 12. For example, when it is possible to specify that a complicated operation on the portable electronic device 1 does not occur, it is determined that a free time has occurred in the processing unit 12. For example, in the state where the case 1C is closed in the portable electronic device 1 having the case 1C of the folding structure shown in FIGS. 1 and 2, no complicated operation occurs on the portable electronic device 1, and the processing unit 12 is free. Time has occurred.

  The main processing unit 12a, for example, when the case opening / closing detection unit 12b detects that the case of the case 1C of the mobile electronic device 1 is closed or the open state is released, It is determined that the processing unit 12 has free time. When the main processing unit 12a determines that there is no free time in the processing unit 12 (step S301: No), the process ends. When the main processing unit 12a determines that the processing unit 12 has free time (step S301: Yes), the main processing unit 12a transfers control to the image display processing unit 12c. Thereby, the image display processing unit 12c executes the standby image generation task 13a, and generates a standby image by the image generation method according to the present embodiment (step S302). The procedure for generating the standby image is the procedure shown in FIG. 8, which is as described above, and will not be described. The generated standby image is stored in a storage area secured as a work area of the storage unit 13, and the image display processing unit 12c ends the standby image generation task 13a.

  When the portable electronic device 1 is not in the standby state (step S303: No), the standby image is not displayed. When the portable electronic device 1 is in a standby state (step S303: Yes), a standby image can be displayed on the display unit 17. Then, the image display processing unit 12c executes the standby image display task 13b and issues a decoding process request to the decoding processing unit 12d. The decode processing unit 12d executes the decode task 13c to read and decode the standby image stored in the work area of the storage unit 13 (step S304). The subsequent processing is the same as step S104 in FIG.

  FIG. 10 is a schematic diagram illustrating an image package file in which a first image candidate group and a plurality of second image candidate groups are packaged as a single data file. In the above description, the first image candidate group and the second image candidate group are stored in the image data storage unit 13f of the storage unit 13 illustrated in FIG. However, the present embodiment is not limited to this, and the first image candidate group and the plurality of second image candidate groups are packaged and handled as a single data file that does not exceed a predetermined data size (for example, 100 kB). The first design information may be stored in the data storage unit 13f. In the present embodiment, an example in which the first image candidate group and the plurality of second image candidate groups and the image generation methods belonging to these groups are packaged as a single data file will be described. However, in the present embodiment, at least The first image candidate group and the plurality of second image candidate groups may be packaged as a single data file.

  FIG. 10 shows an image package file 60. The image package file 60 packages the first image candidate group X and the plurality of second image candidate groups Y1, Y2, Y3, and Y4 and image generation software SWG that describes a method for generating images belonging to these groups, The first design information is handled as a single data file. The image package file 60 is stored in the image data storage unit 13f, and when a standby image is displayed, the image display processing unit 12c of the processing unit 12 reads the image package file 60 from the image data storage unit 13f and waits for the standby image. Is generated. In this case, the image generation software SWG stored in the read image package file 60 is activated, and steps S201 to S206 of the standby image generation task 13a described above are executed. Then, the image generation software SWG selects one first image and two second images, and combines them to generate a standby image.

  Since the image generation software SWG of the image package file 60 generates a standby image in the normal bitmap data format, the decoding (step S103 in FIG. 7 or FIG. 7) in the standby image display procedure shown in FIGS. Step S304 of 9 is not necessary. That is, when the image generation software SWG generates a standby image, the image generation task 13a is terminated, and the display control unit 12e executes the display control task 13d, whereby the standby image of the bitmapped pattern is displayed on the main display 2M. Is displayed.

  The image package file 60 is, for example, Flash, and there is a data file described in Java (registered trademark, the same applies hereinafter). For example, when using Flash, not only stores each image of the first image candidate group X and the plurality of second image candidate groups Y1, Y2, Y3, and Y4 as a drawing object, but also specifies a predetermined background color. In addition, since it is possible to store a command that can realize processing for selecting the first image and selecting the second image from the corresponding second image candidate group, the image generation method according to the present embodiment can be easily realized.

  Since the image package file 60 is handled as a single data file as described above, the data size of image data or the like for generating a standby image becomes clear. For this reason, if the data size of the image package file 60 is restricted at the time of designing the portable electronic device 1, it can operate comfortably within the range of resources of the MPU configuring the processing unit 12. As a result, although many different images (standby images) are frequently displayed, they can operate comfortably within the range of MPU resources, so that the display is slow for the user of the portable electronic device 1 or the like. Less discomfort.

  In addition, when a plurality of irrelevant image data is displayed on the display unit 17 at random, it is impossible for the developer to assume the required size of the image data. As a result, it is not possible to grasp how much MPU resources, storage unit allocation, etc. should be prepared. However, if the data (including software) necessary for the image generation method according to the present embodiment is collected into one image package file 60 and the data size of the image package file 60 is limited, the above-mentioned limitation is imposed. What is necessary is just to allocate the resource of a MPU and a memory | storage part within the range. This also facilitates development.

  Further, if the data size of the image package file 60 is limited and the sizes of the plurality of built-in image package files are set to be approximately the same, different image packages may be used between portable electronic devices having the same hardware specifications. Even when the file 60 is selected and executed, the processing speed is comparable. As a result, if the hardware specifications are the same, there will be almost no difference in processing speed between the mobile electronic devices even though the screens look different. Discomfort of processing speed between devices can be reduced. When the image generation software SWG is also added to the image package file 60, the image generation software SWG is preferably shared between portable electronic devices having the same hardware specifications.

  Incidentally, the image generation software SWG may have various additional functions. As one of them, for example, FIGS. 11A to 11C are explanatory diagrams when the edging process is executed. In the first display control described above, border processing may be performed in which the edge of the object constituting the standby image displayed on the display unit 17 of the mobile electronic device 1 is different from the object color and the background color. . The border processing is processing for bordering the boundary area between the selected first image and second image and the background with a color different from both the color of the selected first image and second image and the background color. .

  The edging process will be described in detail with reference to FIGS. For convenience of explanation, the border processing when the two images of the first image PX and the second image PY are superimposed is taken as an example, but the number of images is not limited to this. The edging process is performed on the image W after the first image PX and the second image PY are overlaid. The first image PX is composed of the background BG1 and the object Obx, and the second image PY is composed of the background BG2, the object Oby1 and the object Oby2. In the border processing, the region Obex between the object Obx of the first image PX and the background BG1, the region Obey1 between the object Oby1 of the second image PY and the background BG2, and the object Oby2 of the second image PY The region Obey2 bordered with the background BG2 is bordered with a color different from the colors of the objects Obx, Oby1, and Oby2 and the backgrounds BG1 and BG2 (background color). The color of the border is called the border color. Here, the color of the background BG1 of the first image PX and the color of the background BG2 of the second image PY are the same color.

  As shown in FIG. 11-2, the region R1 where the object Ob1 of the first image PX and the object Oby2 of the second image PY overlap each other, and the object Ob1 of the first image PX as shown in FIG. 11-3. The border processing is not performed on the region R2 where the object Oby1 of the second image PY contacts each other. That is, in the example illustrated in FIG. 11B, the border processing is performed on the region excluding the region R1 (boundary regions Obex and Obey2), and in the example illustrated in FIG. 11-3, the region excluding the region R2 (boundary region). Border processing is performed on the areas Obex and Obey1).

  When executing the edging process, background color information indicating the background colors of the first image PX and the second image PY is stored in the image data storage unit 13f of the storage unit 13. Then, in the first display control described above, the image display processing unit 12c of the processing unit 12 displays the regions Obex, Obey1, and Obey2 between the selected first image PX and second image PY and the background thereof. The first image PX and the second image PY are bordered by coloring with a color different from the background color. The colors of the border areas Obex, Obey1, and Obey2 are colored by the image display processing unit 12c by selecting different colors from the selected first image PX and second image PY and the background color information. Alternatively, a border color may be determined in advance and specified by the image generation software SWG.

  FIG. 12 is a schematic diagram showing an image package file in which a first image candidate group, a plurality of second image candidate groups, and background color information are packaged as a single data file. When executing the edging process, the first image candidate group, the plurality of second image candidate groups, and the background color information may be stored in the image data storage unit 13 f of the storage unit 13. However, the present invention is not limited to this. Image data as first design information that is handled as a single data file in which the first image candidate group, the plurality of second image candidate groups, and the background color information are packaged. It may be stored in the storage unit 13f. At this time, the single data file is set so as not to exceed a predetermined data size (for example, 100 kB). In this embodiment, an example in which a first image candidate group, a plurality of second image candidate groups, background color information, a method of generating images belonging to these groups, and a method of border processing are packaged as a single data file will be described. However, in the present embodiment, at least the first image candidate group, the plurality of second image candidate groups, and the background color information may be packaged as a single data file.

  FIG. 12 shows an image package file 61. The image package file 61 describes a first image candidate group X, a plurality of second image candidate groups Y1, Y2, Y3, and Y4, background color information BGC, a method for generating an image, and a method for border processing. The first design information is packaged with the image generation software SWG and handled as a single data file. The image package file 61 is stored in the image data storage unit 13f. When displaying a standby image, the image display processing unit 12c of the processing unit 12 reads the image package file 61 from the image data storage unit 13f and performs border processing. A standby image to which is applied is generated.

  As the image package file 61, for example, there is a data file described in Flash, Java, or the like. For example, in the case of using Flash, since the first image is selected, the second image is selected from the second image candidate group corresponding to the first image, and further, the processing for executing the trimming process is included. The image generation method according to the embodiment can be easily realized. The advantages of using the image package file 61 are the same as the advantages of using the image package file 60 described above.

  In Flash, an image is configured by a solid background with a background color, an object to be displayed on the background, and a process for determining how to move the object. When Flash is used as the image package file 61, in the present embodiment, the first image and the second image correspond to objects, so there are a plurality of objects. In the flash processing, the border processing described above is performed with a predetermined color, that is, a color different from the background color and the object color.

(Embodiment 2)
In the second embodiment, a first image candidate group and a plurality of second image candidate groups are prepared as first design information, and a plurality of design information having image information different from the first design information is prepared. Based on the manufacturing ID of the portable electronic device, either the first display control using the first design information or the second display control using the second design information different from the first design information Thus, the standby image is displayed on the display unit.

  In the present embodiment, a standby image having a design that matches the design of the casing of the portable electronic device, for example, the color, pattern, and shape of the casing, is generated using a plurality of design information. Therefore, a plurality of pieces of ID information and a plurality of pieces of design information having different image information are associated with each other, and information that uniquely indicates the design of the casing of the portable electronic device is included in a part of the manufacturing ID. Include. Then, ID information corresponding to at least a part of the manufacturing ID of the own device is searched from a plurality of ID information, and design information corresponding to the searched ID information is set as a standby image displayed on the display unit.

  FIG. 13 is a diagram illustrating an example of a manufacturing ID assigned to a portable electronic device. FIG. 14 is a data table showing the relationship between ID information and an image package file corresponding to the ID information. FIG. 15 is a table describing the contents of the image package file shown in FIG. As shown in FIG. 13, in the present embodiment, the manufacturing ID of the portable electronic device is represented by a 3-digit character string and a 7-digit number sequence. Among these numbers, a 7-digit number sequence is assigned to each portable electronic device in the order of manufacturing the portable electronic device, that is, a manufacturing number. In the present embodiment, information that uniquely indicates the design of the casing of the portable electronic device (hereinafter referred to as casing design information) is included in a part of the character string composed of KCK in order from the first digit. included.

  More specifically, case design information is described in the third digit from the top of the character string. Since the housing design information is associated with the housing design of the portable electronic device on a one-to-one basis, the housing design information uniquely determines the housing design of the portable electronic device. In the present embodiment, since the housing design information uniquely indicates the color of the housing, a part of the character string included in the manufacturing ID uniquely indicates the color of the housing of the portable electronic device. Information.

  As described above, in the present embodiment, the housing design information of the portable electronic device is included in at least a part of the manufacturing ID, more specifically, the character string constituting the manufacturing ID. That is, in the present embodiment, the housing design information is included in the manufacturing ID, and the manufacturing ID is configured together with the manufacturing number. As described above, in the present embodiment, the housing design information is described in a different digit from the serial number that distinguishes the device itself from other portable electronic devices, so the housing design information and the manufacturing number are irrelevant. become.

  As shown in the data table 70 of FIG. 14, in the present embodiment, a plurality of ID information K, Q, P and a plurality of image package files FL1, FL2, FL3 are associated with each other. Note that the number of image package files is not limited to three. As described in the first embodiment, the image package file is a package of at least the first image candidate group and the second image candidate group as a single data file, and is displayed on the display unit of the portable electronic device. This is design information that determines the design of the standby image. The ID information is information that uniquely indicates the design (color in this example) of the casing of the portable electronic device. Therefore, when the ID information is K, it indicates that the color of the casing of the portable electronic device is black, and when the ID information is Q, it indicates that the color of the casing of the portable electronic device is black and white, When the ID information is P, it indicates that the color of the casing of the portable electronic device is pink.

  Each of the plurality of image package files FL1, FL2, and FL3 includes at least a first image candidate group and a second image candidate group as image information of a standby image displayed on the display unit of the portable electronic device. The contents of the image information such as the background color of the image and the design of the object displayed on the background are different between the image package files FL1, FL2, and FL3. For example, as shown in the table 76 of FIG. 15, the image information such as the background color and the object color is different between the image package files FL1, FL2, and FL3. In this case, all the image information may be different between different image packages, or a part of the image information may be different.

  The image information of each image package file FL1, FL2, FL3 is changed according to the corresponding ID information. For example, when the ID information is K, since the color of the casing of the portable electronic device is black, the background color of the standby image, the color of the object displayed on the background, or the background color also corresponds to the color of the casing. Make the color calmer. When the ID information is P, the color of the casing of the portable electronic device is pink, so the background color of the standby image, the color of the object displayed on the background, or the background color is also a pastel color that matches pink. To. Then, by generating a standby image using an image package file corresponding to the ID information, it is possible to display a standby image that matches the case color image of the portable electronic device.

  FIG. 16 is a data table showing the relationship between ID information and an image package file that can realize a border color corresponding to the ID information. FIG. 17 is a table describing the contents of the image package file shown in FIG. The data table 71 shown in FIG. 16 is displayed on the display unit of the portable electronic device, for example, the border color (border color) of the standby image is matched with the image of the case design (case color in this embodiment). Used when.

  In the present embodiment, a plurality of ID information K, Q, and P are associated with a plurality of image package files (design information) FL4, FL5, and FL6, respectively. Note that the number of image package files is not limited to three. Each of the plurality of image package files FL4, FL5, and FL6 includes at least the first image candidate group, the second image candidate group, and border color information as image information of a standby image to be displayed on the display unit of the portable electronic device. . In each of the image package files FL4, FL5, and FL6, as shown in the table 77 of FIG. 17, the edge color of the object displayed on the background is associated with the ID information.

  Each of the image package files FL4, FL5, and FL6 has a border color changed according to the corresponding ID information. For example, when the ID information is K, since the color of the casing of the portable electronic device is black, the border color of the object displayed on the background of the standby image is also black that matches the color of the casing. When the ID information is Q, since the color of the casing of the portable electronic device is black and white, the border color is gray corresponding to the color of the casing. When the ID information is P, the border color is also pink that matches the color of the housing. Then, by generating a standby image using an image package file corresponding to the ID information, it is possible to display a standby color standby image that matches the casing color image of the portable electronic device.

  Since the manufacturing ID of the portable electronic device includes the housing design information, the ID information corresponding to the housing design information included in the manufacturing ID of the own device is searched from a plurality of ID information K, Q, and P. To do. Since the ID information uniquely indicates the design of the casing of the portable electronic device, a standby image corresponding to the design of the casing of the own device is generated in the image package file corresponding to the ID information searched in this way. Data that can be saved. Therefore, by generating a standby image using an image package file selected based on the manufacturing ID of the own device including the case design information, the standby image matching the image of the case color of the own device is displayed. Can do.

  In the present embodiment, control for displaying a standby image using a certain image package file as first design information from among a plurality of image package files is referred to as first display control. The second display control is a control for displaying a standby image using an image package file having image information different from the first design information as the second design information from among a plurality of image package files. . In the present embodiment, as described above, since the image package file corresponding to the manufacturing ID is selected from the plurality of image package files, the second design information is used based on the manufacturing ID of the portable electronic device. The standby image is displayed by one of the display control No. 2 and the first display control.

  In the above description, an example in which a standby image that matches the image of the color of the casing has been described, but a standby image having a design that matches the image of the shape and pattern of the casing may be displayed. For example, if the shape of the housing is square, the object to be displayed on the background is designed to be square, or if the shape of the housing is rounded, the object to be displayed in the background is designed to have a curve. Or

  As described above, in the present embodiment, the first display control using the first design information and the plurality of design information based on the ID information that is information that uniquely indicates the design of the casing of the portable electronic device. The standby image is displayed on the display unit by any one of the second display control using any one of them. This makes it possible to display a standby image that matches the design image of the housing.

  Here, the image package files FL1 to FL6 are, for example, a package in which at least a first image candidate group and a plurality of second image candidate groups are packaged as image information and does not exceed a predetermined data size (for example, 100 kB). It is handled as a data file. The image package files FL1 to FL6 may include image generation software describing a method for generating images belonging to the first image candidate group and the plurality of second image candidate groups.

  Examples of such a packaged image data file include a data file described in Flash, Java, or the like. Thus, the advantages of using the image package files FL1 to FL6 that are packaged and handled as a single data file are the same as the advantages of using the image package file 60 described in the first embodiment. Next, functions of the portable electronic device according to the present embodiment will be described.

  FIG. 18 is a block diagram illustrating functions of the mobile electronic device according to the second embodiment. The portable electronic device 1a according to this embodiment is different from the portable electronic device 1 according to the first embodiment in that the processing unit 12 has an activation unit 12g, the storage unit 13 has an activation task 13g, a manufacturing ID storage unit 13h, and a setting. The difference is that a storage unit 13i and a data table storage unit 13j are additionally provided. Other configurations of the portable electronic device 1 a are the same as those of the portable electronic device 1.

  The function of the activation unit 12g is realized by executing a task assigned by the main processing unit 12a by hardware resources configured by the processing unit 12 and the storage unit 13. In the present embodiment, the function of the activation unit 12g is realized by the activation unit 12g executing the activation task 13g. As described above, the function of the activation unit 12g is realized by executing the activation task 13g by the processing unit 12. Therefore, in the processing unit 12, the main processing unit 12a, the activation unit 12g, and the like are not physically distinguished from each other. In the processing unit 12, the main processing unit 12a, the activation unit 12g, and the like may be physically distinguished from each other, that is, may be configured as dedicated hardware for realizing each function.

  The start task 13g is executed when the mobile electronic device 1a is powered on. The activation task 13g is, for example, after the portable electronic device 1a is shipped from the factory or after being repaired and reset (the processing unit 12 and the storage unit 13 are initialized). When the power is turned on, it has a function of setting a standby image displayed on the display unit 17 of the portable electronic device 1a based on the manufacturing ID of the portable electronic device 1a.

  The manufacturing ID storage unit 13h stores the manufacturing ID of the portable electronic device 1a, and the setting storage unit 13i stores the initial setting information of the portable electronic device 1a that is set when the activation unit 12g executes the activation task 13g. Is done. The data table storage unit 13j stores the data table 70 and the data table 71 described above as data necessary for initial setting of the portable electronic device 1a. Next, in this embodiment, a procedure for setting an image displayed on the portable electronic device and generating the set image will be described.

  FIG. 19 is a flowchart illustrating a procedure for setting an image displayed on the portable electronic device and generating the set image in the second embodiment. FIG. 20 is a schematic diagram illustrating a standby image management table stored in the storage unit. First, at the design stage of the portable electronic device 1a, for example, as shown in the data table 70 of FIG. 14, the ID information and the image package file are associated with each other. The data table 70 is stored in the data table storage unit 13j of the storage unit 13 of the portable electronic device 1a illustrated in FIG. Then, when setting the standby image displayed on the display unit 17 of the portable electronic device 1a, the processing unit 12 refers to the data table 70 stored in the data table storage unit 13j. Further, the data table 70 may be described in, for example, an activation task 13g or an application program including the activation task 13g. In any aspect, information in which the ID information is associated with the design information is stored in the storage unit 13. In the manufacturing stage of the portable electronic device 1a, the manufacturing ID of the device itself is stored in the manufacturing ID storage unit 13h of the storage unit 13 shown in FIG.

  In the manufacturing stage of the portable electronic device 1a, software necessary for realizing the function of the portable electronic device 1a is installed in the storage unit 13 shown in FIG. The software includes the above-described standby image generation task 13a, standby image display task 13b, decode task 13c, display control task 13d, file system control task 13e, and startup task 13g. In this way, the portable electronic device 1a is completed. Next, a procedure for setting a standby image displayed on the display unit 17 of the portable electronic device 1a will be described with reference to FIG. Next, for example, a case will be described in which a standby screen displayed after the first power activation is set after the reset of the portable electronic device 1a, such as after the portable electronic device 1a is manufactured and shipped.

  When the portable electronic device 1a is completed, the portable electronic device 1a is turned on before shipping. Thereby, it is confirmed whether the portable electronic device 1a is activated and whether incoming and outgoing calls can be executed. Further, the display state of the main display 2M and the sub display 2S constituting the display unit 17 shown in FIG. 18 is adjusted. In the confirmation of incoming / outgoing calls, since the history of incoming / outgoing calls remains in the storage unit 13 of the portable electronic device 1a, this history is erased before shipment. When the incoming and outgoing calls of the portable electronic device 1a are confirmed, the incoming and outgoing histories are erased from the storage unit 13 of the portable electronic device 1a by resetting the portable electronic device 1a. And the portable electronic device 1a is boxed and shipped to each store.

  When the portable electronic device 1a is purchased, the portable electronic device 1a is turned on, for example, at a store for various settings and operation confirmation (step S401). Thereby, the portable electronic device 1a starts to start. Then, the main processing unit 12a transfers control to the activation unit 12g. That is, the main processing unit 12a allocates the hardware resources of the processing unit 12 and the storage unit 13 to the startup task 13g. As a result, the activation unit 12g executes the activation task 13g.

  When the activation task 13g is executed, the activation unit 12g determines whether or not the setting completion flag F1 = 1 is stored in the flag management area assigned to the setting storage unit 13i of the storage unit 13 illustrated in FIG. (Step S402). Accordingly, the activation unit 12g determines whether or not the portable electronic device 1a is the first power activation after the reset. Here, the setting storage unit 13i includes an EEPROM (Electrically Erasable Programmable ROM) which is a kind of EPROM (Erasable Programmable ROM).

  When the setting completion flag F1 = 1 is not satisfied, that is, when F1 = 0, the portable electronic device 1a is the first power-on after reset and sets a standby image to be displayed on the display unit 17 (hereinafter referred to as display image setting). ) Can be determined to be incomplete. When it is determined that the activation unit 12g is not F1 = 1 (step S402: No), it can be determined that the display image setting has not been completed. In this case, the activation unit 12g reads the manufacturing ID of the own device from the manufacturing ID storage unit 13h of the storage unit 13 (step S403). Then, the activation unit 12g searches the plurality of ID information for at least a part of the read manufacturing ID, that is, ID information corresponding to the housing design information (step S404).

  For this reason, in step S404, the activation unit 12g acquires the case design information included in the read manufacturing ID. Then, the activation unit 12g reads the data table 70 illustrated in FIG. 14 and searches the plurality of ID information described in the data table 70 for ID information that matches the acquired housing design information. For example, since the manufacturing ID shown in FIG. 13 is KCK0000001, the ID information that matches the housing design information described in the last digit of the character string consisting of KCK is K. The ID information searched in this way corresponds to the manufacturing ID of the own device.

  Based on the ID information corresponding to the manufacturing ID of the own device, the design of the housing of the own device is specified (step S405). If the manufacturing ID KCK0000001 shown in FIG. 13 is the manufacturing ID of the own device, the ID information is K. Therefore, the housing design (color) of the own device is determined from the relationship between the ID information shown in the data table 70 and the housing color. ) Can be identified as black.

  Next, the activation unit 12g adds a standby image that matches the design of the casing of the own device to the standby image management table 65 shown in FIG. 20 (step S206). Here, the standby image management table 65 shown in FIG. 20 will be described. The standby image management table 65 is stored in the image data storage unit 13f of the storage unit 13 shown in FIG. The standby image management table 65 describes image candidates (images 1 to 5) to be displayed as standby images.

  The standby image management table 65 has an area (image storage area) for storing six pieces of image data. In the standby image management table 65, five pieces of image data are already stored, and one free area is prepared. More specifically, the NO. 1 to NO. Image data is already stored in the image storage areas up to 5, and NO. The image storage area 6 is a free area BL.

  In the standby image management table 65, an area for describing the standby image selection flag F2 is provided for each image storage area. When the standby image selection flag F2 is set to 1, the image stored in the corresponding image storage area is set as the standby image displayed on the display unit 17 of the own device. Here, the standby image selection flag F2 is not set to 1 for two or more image storage areas. That is, only one standby image is selected from the standby image management table 65.

  In step S406, when the activation unit 12g adds a standby image that matches the design of the casing of the own device to the standby image management table 65, the activation unit 12g first selects a standby image that matches the design of the casing of the own device. An image package file that can be generated is acquired from the data table 70 shown in FIG. Since the data table 70 is associated with ID information and a plurality of design information, the activation unit 12g calls the data table 70 to design information corresponding to the ID information acquired in step S404, more specifically. Get the image package file. For example, when the ID information acquired in step S404 is K, the image package file FL1 is acquired from the data table 70.

  The activation unit 12g acquires the image package file corresponding to the ID information acquired in step S404 from the data table 70, and writes it in the empty area (area indicated by NO. 6) of the standby image management table 65. As a result, an image package file that can generate a standby image that matches the design of the housing of the device itself is added to the standby image management table 65. Next, the activation unit 12g selects the image package file (FL1 in this embodiment) added in step S406, and sets the standby image selection flag F2 to 1 (step S407). As a result, when the portable electronic device 1a is on standby, an image with the standby image selection flag F2 = 1 is displayed on the display unit 17 as a standby image.

  The image package file added to the standby image management table 65 is not deleted unless the portable electronic device 1a is reset. For this reason, when the user changes the default standby image and wants to return to the default image again, the initial setting can be performed by simply changing the standby image setting without resetting the portable electronic device 1a. It is possible to return to the standby image.

  By the way, after resetting the device itself, the border color of the object displayed on the background may be matched with the image of the case color of the portable electronic device 1a as the standby image displayed first. In this case, in step S406, using the data table 71 shown in FIG. 16, an image package file that can realize a border color corresponding to the housing color of the device itself may be added to the standby image management table 65.

  In addition, when performing the edging process with the color corresponding to the manufacturing ID, at least the first image candidate group, the second image candidate group, and information on the edging color of the object displayed on the background (framing color information) are simply set. It is assumed that the image package file is handled as one data file. At this time, a plurality of ID information and a plurality of border color information are associated with each other, and the image package file includes a plurality of border color information associated with a plurality of ID information. After configuring the image package file in this way, at least a part of the manufacturing ID, that is, ID information corresponding to the housing design information is searched from a plurality of ID information. Then, the border processing of the object displayed on the background may be performed with the color of the border color information corresponding to the searched ID information.

  When the setting of the standby image is completed, the activation unit 12g rewrites the setting completion flag F1 stored in the flag management area assigned to the setting storage unit 13i to 1 (step S408). When the setting completion flag F1 is rewritten to 1, the startup task 13g is completed. When the activation task 13g is completed, the activation unit 12g issues a completion notification to the main processing unit 12a. Receiving the completion notification, the main processing unit 12a changes the portable electronic device 1a to the standby state after the activation of the portable electronic device 1a is completed.

  The standby state is a state in which the mobile electronic device is waiting for an incoming call, and a standby image is displayed on the main display 2M in the standby state. After transitioning to the standby state, the main processing unit 12a transfers control to the image display processing unit 12c. That is, the main processing unit 12a allocates the hardware resources of the processing unit 12 and the storage unit 13 to the image display processing unit 12c. As a result, the image display processing unit 12c executes the standby image generation task 13a. Then, the image display processing unit 12c generates a standby image from the image package file corresponding to the standby image selection flag F2 = 1 (step S409).

  When the image display processing unit 12c executes the standby image generation task 13a, the image generation software included in the image package file corresponding to F2 = 1 is activated. The image generation software selects a plurality of first images belonging to the first image candidate group included in the image package file. Then, at least two second images are selected from the second image candidate group included in the image package file corresponding to F2 = 1 and corresponding to the selected first image.

  When one first image and at least two second images are selected, the image generation software combines the data file of one selected first image and the data files of two second images. These procedures executed by the image generation software are the same as steps S201 to S206 in the first embodiment. Accordingly, a standby image that matches the design image of the casing of the portable electronic device can be generated. When the standby image is generated, the image display processing unit 12c temporarily stores the generated standby image in a storage area secured as a work area of the storage unit 13, and ends the standby image generation task 13a.

  When the image display processing unit 12c generates a standby image, the image display processing unit 12c issues a standby image display request to the display control unit 12e. The display control unit 12e executes the display control task 13d to display the standby image of the bitmapped pattern on the display unit 17, more specifically, the main display 2M (step S410). Thereafter, the display control unit 12e issues a completion notification to the image display processing unit 12c, and the display of the standby image is completed.

  Next, it returns to step S402 and demonstrates. If it is determined that the activation unit 12g is F1 = 1 (step S402: Yes), it can be determined that the display image setting is completed. In this case, the startup task 13g ends. When the activation task 13g is completed, the activation unit 12g issues a completion notification to the main processing unit 12a. Receiving the completion notification, the main processing unit 12a changes the portable electronic device 1a to the standby state after the activation of the portable electronic device 1a is completed.

  After transitioning to the standby state, the main processing unit 12a transfers control to the image display processing unit 12c. The image display processing unit 12c checks the standby image management table 65 (step S411), and searches for an image package file with the standby image selection flag F2 = 1. Then, the image display processing unit 12c executes the standby image generation task 13a to generate a standby image from the image package file corresponding to the standby image selection flag F2 = 1 (step S409). Then, the display control unit 12e displays a standby image of a bitmapped pattern on the main display 2M (step S410).

  According to the above procedure, a standby image displayed on the display unit 17 after the first power activation after the reset of the portable electronic device 1a is set. If the user wants to change the standby image or menu image, the standby image selection flag F2 is set for the image selected by the user. As a result, an image with the standby image selection flag F2 = 1 is read from the image data storage unit 13f and displayed on the display unit 17 as a standby image or a menu image. By using the image setting method according to the present embodiment, as described above, it is possible to display a standby image that matches the design image of the casing constituting the portable electronic device 1a.

  Usually, the user who purchases a portable electronic device is biased by the design of the casing of the portable electronic device. For example, if the housing color is pink or the shape is rounded, many women will purchase, and if the housing color is cold or the shape is linear, many men will purchase. There is a tendency to buy. Here, in the conventional design / manufacturing method, there is a single standby image, menu image, animation image, or the like set in advance for the portable electronic device, and the one corresponding to the design of the housing is always displayed first. is not. As a result, there is a tendency that the user's preference is too far from the purchased user's preference.

  In such a case, the purchased user needs to switch the displayed image using a function setting menu or an instruction manual provided in the portable electronic device. If a user is unfamiliar with the handling of the portable electronic device, the image switching operation is often difficult, and a situation in which the use of the portable electronic device is continued in a state set at the time of shipment may occur. On the other hand, manufacturers of portable electronic devices can solve the questions and complaints by notifying users that questions and complaints can be switched by setting the functions of the portable electronic devices. Occur.

  To solve these problems, the software to be installed on the mobile electronic device is divided for each design of the housing of the mobile electronic device, and the standby image or menu image that matches each design is displayed. It can be solved if it is a process. However, dividing the software to be installed in the portable electronic device into a plurality of systems itself is a risk because it reduces the production efficiency and is likely to cause mistakes.

  For example, in the manufacturing process of a portable electronic device, there is a possibility that software for pink may be mistakenly installed in a portable electronic device having a black housing. In this case, a standby image or menu image that does not match the color image of the casing is displayed. In addition, since a bug in the software has been corrected, if it becomes necessary to download the corrected software to a portable electronic device, the software development department may leak the correction for the software corresponding to the design of a certain case There is. This is a human error that occurs because the software to be installed in the portable electronic device is divided into a plurality of pieces.

  In the present embodiment, a manufacturing ID, which is a unique identification mark of the portable electronic device, is used as a means for determining the design of the casing constituting the portable electronic device. Thus, the design of the casing included in the portable electronic device can be determined, and the setting of the standby image can be matched with the design of the casing. As a result, even when there is a restriction that one image must be selected as the initial state in the design development of the image displayed on the display unit of the portable electronic device, the design that matches the design image of each case Can be set in advance in the portable electronic device as initial setting information. As a result, the portable electronic device can reduce the difference between the image of the housing design and the image of the image. As a developer of the portable electronic device, there is an advantage that a standby image that matches the design image of the housing can be displayed.

  Moreover, it is not necessary for a person who plans or develops a portable electronic device to separately prepare software to be installed for each design of the casing of the portable electronic device. That is, the design information (information about the design of the image displayed on the display unit 17) is stored in the storage unit, and the correspondence between the manufacturing ID of the portable electronic device and the design information is specified, so that the portable electronic Only one type of software needs to be installed on the device. Software installation can be performed in the same process. As a result, even when a plurality of designs of the casing of the portable electronic device are set and many variations of the casing are deployed, an increase in manufacturing cost of the portable electronic device can be significantly suppressed with a simple configuration.

  Further, as described above, only one type of software needs to be installed on the portable electronic device. Therefore, in this embodiment, the planner and the developer individually intend for each design of the housing while avoiding the danger caused by preparing a plurality of software installed in the portable electronic device with a simple configuration. There is also an advantage that the lineup as established can be established. In addition, by optimizing the initial setting information in the development stage, it is possible to reduce the case where the user's preference is excessively deviated.

  Further, as a mobile electronic device sales company, different standby images can be presented for each mobile electronic device having a different housing design. For this reason, it becomes easy to develop a service according to the user's tendency, and as a result, there is an advantage that a service that the user wants to use as a sales company can be further appealed. Furthermore, the user who purchased the portable electronic device can have the portable electronic device in which the design of the housing and the design of the image displayed on the display unit are unified. Since standby images and menu images having a design that matches the image of the housing design are initially set, there is an advantage that it is possible to save the trouble of resetting these images in advance.

  In the present embodiment, after the correspondence relationship between the manufacturing ID and the design information is set, the setting is stored in the storage unit. Specifically, the standby image selection flag F2 is set to 1 and stored in the storage unit for the standby image that matches the design of the casing of the portable electronic device. This eliminates the need to read the manufacturing ID or search the ID information every time the portable electronic device is powered on. As a result, it is possible to avoid an increase in the time required for power activation. In the case of a foldable case, it is not necessary to read the manufacturing ID or search the ID information every time the case is changed to the open state. As a result, it is possible to avoid an increase in time required for displaying the standby image.

  Further, the housing design information is included in the manufacturing ID of the portable electronic device so as to be independent of the manufacturing number. The housing design information is used to determine the housing design of the device itself, and a corresponding standby image, menu image, or the like is set. For this reason, even if a portable electronic device is additionally manufactured and the serial number is increased, the case design of the portable electronic device can be determined by referring to the case design information included in the manufacturing ID of the portable electronic device. . Thus, if the housing design information, the ID information, and the design information included in the manufacturing ID of the portable electronic device are associated with each other, there is no need to recreate a data table or a startup task. As a result, in the present embodiment, there is also an effect that it is possible to flexibly cope with additional manufacturing of the portable electronic device.

  In the above procedure, the case where the power is turned on for the first time after the portable electronic device is shipped from the factory has been described, but the same applies to the case where the portable electronic device is reset by repairing the portable electronic device or the like. Also in this case, according to the present embodiment, the design of the casing that constitutes the portable electronic device is determined using the manufacturing ID of the portable electronic device, and the standby image that matches the image of the casing design is displayed. be able to.

  As described above, the portable electronic device according to the present invention is useful for realizing a reduction in the volume of an image displayed on the display unit and displaying various designs with changes on the display unit of the portable electronic device. is there.
