  With reference to FIG. 2, the configuration of mobile phone 100 according to the embodiment of the present invention will be further described. FIG. 2 is a block diagram showing the main configuration of mobile phone 100.

  As shown in FIG. 2, the mobile phone 100 includes an arithmetic device 110, a main monitor 120, a sub-monitor 130, a camera 140, an operation button 150, a numeric button 160, a RAM (Random Access Memory) 172, A flash memory 174, a memory card drive 180, and an antenna 190 are included. A memory card 182 is attached to the memory card drive 180. The arithmetic device 110 functions as a determination unit, a first generation unit, and a second generation unit that execute each process described later while a program for executing a predetermined process is operating.

  That is, the determination unit of the arithmetic device 110 determines whether a file stored in the flash memory 174 is associated with image data unique to the file, based on the name of the file or an extension. To do.

  When the file is associated with the image data, the first generation unit of the arithmetic device 110 generates data for displaying an image corresponding to the image data on the main monitor 120 from the image data. . This image data is generated, for example, by thinning out data stored at predetermined intervals.

  When the file is not associated with the image data, the second generation unit of the arithmetic device 110 is based on the attribute-specific image data associated with the attribute of the file and the identification information of the file. Thus, data to be displayed on the main monitor 120 is generated. At this time, similarly to the first generation unit, the data for display is generated by thinning out data stored in the flash memory 174 at predetermined intervals, for example.

  In addition, the aspect which produces | generates the data for a display is not restricted to said thing, You may produce | generate in another aspect.

  The arithmetic device 110 further executes other predetermined processing based on the data and program stored in the flash memory 174. This processing includes a call with another mobile phone via the antenna 190, transmission / reception of mail, display of an image on the main monitor 120 or the sub monitor 130, and the like.

  The sub monitor 130 is attached to the opposite surface (not shown) of the main monitor 120 of the mobile phone 100 shown in FIG. The camera 140 is also attached to the same surface as the surface to which the sub monitor 130 is attached.

  The operation buttons 150 include, for example, a cursor movement key, a power key, a determination key, and the like.

  The RAM 172 is, for example, a volatile memory for temporarily storing data when the arithmetic device 110 executes processing. The RAM 172 may be plural. Further, a VRAM (Video RAM) for image display may be further provided.

  The flash memory 174 stores a program executed by the arithmetic device 110, preset data, and the like. This data includes, for example, the type of file and image identification data (for example, icon) created in advance according to the type. These are stored in association with each other.

  The flash memory 174 further stores photographs and other image data, music data, text data, and the like. Some of the data is generated by a user of the mobile phone 100, and some is acquired by communicating via the antenna 190.

  The data for the user can be recorded on an information recording medium other than the flash memory 174. For example, image data or other data may be written to a memory card 182 mounted in the memory card drive 180.

  Conversely, the cellular phone 100 according to the present invention may not have the memory card drive 180.

  The data stored in the flash memory 174 of the mobile phone 100 will be described with reference to FIG. FIG. 3 is a diagram for explaining the identifier of the file stored in the flash memory 174 and the type of the file.

  As shown in FIG. 3, for example, the identifier “JPG” is associated with “picture” as the file type. Similarly, for example, an identifier “TXT” is associated with “text” as a file type. The correspondence relationship between the identifier and the file type is not limited to the mode shown in FIG.

  By setting such a correspondence relationship in advance, for example, the arithmetic device 110 can determine that a file having the identifiers “JPG”, “ANI”, or “MOV” is image data.

A data reference format in the flash memory 174 of the mobile phone 100 will be described with reference to FIG. 4A to 4C are diagrams for explaining the correspondence between folders storing data.

  Referring to FIG. 4A, for example, reference to address “2” for the name “data folder” is shown. As shown in FIG. 4B, the address “2” of the data folder designates the name “picture folder” and the reference “3” for the address.

  As shown in FIG. 4C, the address “0010” of the image data whose name is “A.JPG” is stored in the address “3” designated in the picture folder.

  In this way, the address of the image data to be displayed is specified based on the address specified in the root file of the flash memory 174. Note that data storage in the flash memory 174 is not limited to the mode shown in FIG.

  With reference to FIG. 5, display of an image on main monitor 120 of mobile phone 100 according to the present embodiment will be described. FIG. 5 is a diagram for explaining a plurality of display areas displayed on the main monitor 120.

  As shown in FIG. 5, the display area of the main monitor 120 includes an image display area 500, a screen information display area 510, and a function display area 520. The image display area 500 is subdivided into nine areas. This subdivision is performed when a predetermined condition is satisfied. For example, when the user inputs an instruction to display a list of images, the image display area 500 is subdivided, and an image or a character is displayed in each area.

  The subdivision mode of the image display area 500 is not limited to that shown in FIG. For example, the number of regions generated by subdivision may be other than nine. The regions do not have to be adjacent to each other.

  Screen information display area 510 represents information related to the screen displayed on main monitor 120. This information includes, for example, menu headings and the like.

  The function display area 520 displays functions that can be used on the screen displayed by the main monitor 120. This display is assigned to the operation button 150 of the mobile phone 100. Therefore, for example, when the user moves the cursor to one of the displays and presses the enter key, the function assigned to the display is executed.

  With reference to FIG. 6, a control structure of mobile phone 100 according to the embodiment of the present invention will be described. FIG. 6 is a flowchart showing a procedure of processing executed by arithmetic device 110 of mobile phone 100. This process is executed by a program stored in the flash memory 174, for example.

  In step S602, computing device 110 detects the pressing of the operation button by the user.

  In step S604, computing device 110 determines whether display of an image list has been instructed. This determination is made based on, for example, whether a signal is output based on pressing of an operation button associated with an instruction to display an image list. If it is determined that display of an image list has been instructed (YES in step S604), the process proceeds to step S608. If not (NO in step S604), the process proceeds to step S610.

  In step S <b> 608, arithmetic device 110 reads data stored in flash memory 174 to RAM 172. At this time, data corresponding to the display area of the main monitor 120 is read out. That is, when the amount of data necessary for displaying an image in the divided display area on the main monitor 120 is smaller than the amount of data stored in the flash memory 174, the amount of data necessary for display in the display area is read out. . For example, when the main monitor 120 is divided into three equal parts in the vertical and horizontal directions and divided into nine parts on the entire screen, one-ninth of the data amount stored in the flash memory is read out. Note that the mode of reading data is not limited to this, and other modes may be used.

  In step S610, arithmetic device 110 executes other predetermined processes.

  In step S612, arithmetic unit 110 determines whether or not data reading has been completed for all files. If it is determined that data reading has been completed (YES in step S612), the process proceeds to step S616. If not (NO in step S612), the process proceeds to step S614.

  In step S614, arithmetic unit 110 reads the data of the next file into RAM 172.

  In step S616, arithmetic unit 110 initializes counter CNT.

  In step S618, arithmetic device 110 determines whether or not the file read to RAM 172 is a file having image data. This determination is made based on, for example, an extension attached to the file or attribute data associated with the file name. If the file read into RAM 172 is a file having image data (YES in step S618), the process proceeds to step S620. If not (NO in step S618), the process proceeds to step S626.

  In step S620, arithmetic device 110 determines whether or not the image data is developable data. This determination is made based on whether or not the data read into the RAM 172 can be fully developed, for example. If the image data is developable data (YES in step S620), the process proceeds to step S622. If not (NO in step S620), the process proceeds to step S624.

  In step S622, arithmetic unit 110 displays only an image based on the image data. That is, the arithmetic device 110 outputs the image data read out to the RAM 172 to the main monitor 120. As a result, the main monitor 120 displays an image corresponding to the data in any of the image display areas 500 (FIG. 5).

  In step S624, arithmetic unit 110 executes display processing at the time of expansion error. When this process is executed, for example, an error message indicating that the image data cannot be expanded is displayed in a predetermined image display area 500 of the main monitor 120.

  In step S626, arithmetic unit 110 determines an icon based on the file type.

  In step S628, arithmetic unit 110 displays the name of the file and an icon corresponding to the file. That is, the arithmetic unit 110 reads out the data for displaying the icon in the RAM 172 and the data of the file name and outputs the data to the main monitor 172. As a result, the main monitor 120 displays a predetermined icon in accordance with the file type and the name of the file at a predetermined position in the image display area 500. This position is determined based on the reading order when the file is read, for example.

  In step S630, arithmetic unit 110 increments the value of counter CNT by one.

  In step S632, arithmetic unit 110 determines whether the value of counter CNT has reached a predetermined number. If counter CNT reaches a predetermined number (YES in step S632), the process ends. If not (NO in step S632), the process returns to step S618.

  The operation of mobile phone 100 according to the embodiment of the present invention based on the above-described structure and flowchart will be described with reference to FIG. FIG. 7 is a diagram illustrating a state in which the main monitor 120 displays an image in each of the nine areas in the image display area 500 based on the data stored in the flash memory 174.

  When the user of mobile phone 100 presses a predetermined operation button to instruct display of an image list (YES in step S604), image data is read from flash memory 174 to RAM 172 (step S608).

[Operation to display only images]
If the read file is, for example, “A.JPG”, it is determined that the file has image data (YES in step S618), and it is determined whether or not development is possible. If file “A.JPG” is a file that can be expanded (YES in step S620), an image is displayed on main monitor 120 based on the image data of the file (step S622, in FIG. 7). Display 710).

[Operation to display icon and file name]
If display of all files has not been completed (NO in step S632), the same processing is repeated for the file read into RAM 172. At this time, if the file does not have image data (NO in step S618), an icon to be displayed is determined based on the type of the file (step S626). The main monitor 120 displays the file name and icon (step S628, display 720 in FIG. 7).

[Action when a file error occurs]
Thereafter, display processing is further performed on the file read into RAM 172 (NO in step S632). If the file is a file having image data (YES in step S618) and is not developable data. (NO in step S620), arithmetic device 110 executes a predetermined error process (step S624). As a result, the main monitor 120 displays a display indicating that the file is not normal and a file name (display 730 in FIG. 7). For example, referring to FIG. 7, display 730 indicates that a file named “file J.JPG” is not normal.

  With reference to FIG. 8, a display mode in mobile phone 100 according to the embodiment of the present invention will be described. FIGS. 8A and 8B are diagrams for explaining switching of image display on the main monitor 120 of the mobile phone 100. FIG.

  As shown in FIG. 8A, the main monitor 120 displays image data in each area included in the image display area 500 based on a list display instruction from the user. This display includes an image displayed based on normal data, an image image displayed based on damaged data, and an identification image previously associated with a file that originally does not have image data. .

  When the user moves the cursor displayed on the main monitor 120 and selects a specific display area (for example, the display area 810) in the state displayed in this manner, the data is stored in that area. An image is enlarged and displayed based on the data (FIG. 8B). For example, in response to pressing of the display area 810, data for display in that area is output so as to be displayed in the entire image display area 500. In this case, when data for displaying an image in the subdivided area is generated by extracting data at a specific ratio from data for displaying an image in the image display area 500, Is output to the main monitor 120.

  In this case, the main monitor 120 displays only an image and does not display other information (for example, a file name). Therefore, even in the display mode shown in FIG. 8A, the user can easily recognize what the image shown in the specific display area 810 is.

  As described above, according to mobile phone 100 according to the embodiment of the present invention, when a user instructs display of a list of files, the file is imaged based on the attributes of the file stored in advance. It is determined whether or not there is data. The mobile phone 100 displays only an image or displays an image representing a file name and an attribute of the file according to the determination result. Therefore, since the information of the file having the image data is displayed in the entire display area, the user can easily recognize what the file is. Thereby, the mobile phone which can improve the visibility of an image can be provided.

  Note that the manner of storing data in the flash memory 174 is not limited to that shown in FIG. That is, as shown in FIG. 4, data may be specified by a method other than a method of referring to a specific file by referring to an address between a plurality of folders.

  With reference to FIG. 9, another aspect related to data storage in mobile phone 100 will be described. FIG. 9 is a diagram conceptually showing the data structure in flash memory 174.

  As shown in FIG. 9, the flash memory 174 has a plurality of data areas. Each area includes a memory number for specifying the area, a file name to be stored, an image presence / absence flag area indicating the presence / absence of an image, and an area for storing data indicating a file type.

  For example, when the memory number is “001”, the file stored in the memory number is “file A”. This “file A” is a file having an image. This file indicates that it is a picture file.

  Similarly, for example, the data stored in the memory number “006” has the file name “file F”. This “file F” is a file having no image data. This file is a text file. Even in this manner, since it is possible to determine the presence or absence of an image for each file, the mobile phone 100 can selectively display an image based on a list display instruction.

  Furthermore, reading of data to be displayed on the main monitor 120 is not limited to the processing shown in step S612 in FIG. For example, data corresponding to each area when displaying a list of images may be stored in advance and the data may be read out. In this way, for example, if the capacity of the flash memory 174 is sufficient, a list of images can be displayed promptly.
