Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to an information processing device, and to a method for controlling an information processing device. 
         [0003]    2. Description of the Related Art 
         [0004]    Recently, with technology advancement, imaging devices such as digital cameras have been improved so as to have higher performance and function. Many of these imaging devices display information such as set values and conditions concerning shooting conditions using icons so that the information is visible to users. In addition, with improvement of performance and function of these imaging devices, the number of functions settable by users increases, and therefore the amount of the information on shooting conditions increases, resulting in increase of the number of icons displaying the information. 
         [0005]    As mentioned above, the function of icons is to display information such as set values and conditions concerning shooting conditions. However, as the number of the icons displaying the information increases, it becomes difficult for users to understand the meaning of the icons. Particularly when a person used an imaging device, which is commonly used by several persons, icons strange to the person are often displayed in the imaging device after another person uses the imaging device. In this case, the person has to read the instruction manual of the imaging device to know the meanings of the icons and the way to change the set values or to delete the icons. Such an operation is troublesome for the person. 
         [0006]    In attempting to solve the problem, an information processing device is proposed in which multiple icons are displayed in a screen of the device while the screen is separated into multiple areas, and the name of an icon in one of the multiple areas selected by a user is displayed in the screen. 
         [0007]    When a person uses such an information processing device, there is a case in which the person knows the name of the icon in the selected area but cannot understand the meaning and contents of the selected icon and whether or not to change the set condition of the function indicated by the icon. 
         [0008]    For these reasons, there is a need for a user-friendly information processing device, which can display information on an icon or an advice about the function indicated by the icon in the screen thereof so that users can know the meaning of the icon and/or the set value and conditions of the function indicated by the icon and in which users can change the settings of the function indicated by the icon when the information on the icon is displayed in the screen thereof. 
       SUMMARY 
       [0009]    This patent specification describes a novel information processing device, one embodiment of which includes an icon displaying member configured to display multiple icons in a screen thereof to show set contents of the functions or conditions of the information processing device using the icons; a selecting member configured to select at least one of the multiple icons displayed in the screen; a controller configured to allow the icon displaying member to display in the screen at least first information on the selected icon other than the name thereof and second information on a second icon belonging to a category to which the selected icon belongs, and configured to change a set content of a function of the information processing device indicated by the selected icon to a content of a function indicated by the second icon when at least the first-selected icon and the second icon are displayed in the screen and the second icon is selected by the selecting member. 
         [0010]    This patent specification further describes a novel controlling method for controlling an information processing device, one embodiment of which includes displaying multiple icons in a screen of the information processing device to show set contents of the functions or conditions of the information processing device; selecting at least one of the multiple icons displayed in the screen; displaying in the screen at least first information on the selected icon other than the name thereof and second information on a second icon belonging to a category to which the selected icon belongs; and changing a set content of a function of the device indicated by the selected icon to a content indicated by the second icon by selecting the second icon in the screen displaying at least the first-selected icon and the second icon.

         [0050]      FIG. 6A  is a view illustrating a list of category representing icons, i.e., a list of icons C 1 -C 31 , which can be displayed in the LCD monitor  10  in a shootable state of the digital camera. In real shooting, whether or not these icons are displayed is determined depending on the setting and conditions of the digital camera. In addition, there is a case in which another icon belonging to the same category is displayed instead of a category representing icon. For example, the icon C 1  displayed in  FIG. 6  represents a flash mode category and means a mode that flash is not emitted, but the icon may be replaced with another icon belonging to the flash mode category such as a forcible flashing icon depending on the setting of the digital camera. 
         [0051]      FIG. 6B  is a table illustrating the names of the icon categories of the digital camera, i.e., a correspondence table showing the relation between the numbers C 1 -C 31  and the names of the icon categories of the digital camera. 
         [0052]      FIG. 7  illustrates an example of an image displayed in the LCD monitor  10  when the digital camera achieves a still image shooting mode, i.e., an image monitored when the digital camera is in the shootable state. In the image illustrated in  FIG. 7 , icons indicating the conditions or set values of each of the categories of the flash mode, shooting mode, record area, number of remaining exposures, image quality, image size, zoom bar, and battery level are displayed. In this regard, the displayed icons may be different depending on the setting and conditions of the digital camera, namely the icons may be replaced with other icons belonging to the respective categories. 
         [0053]      FIG. 8  is a view illustrating an information displaying icon selection screen image of the digital camera. In the image illustrated in  FIG. 8 , an icon  30  indicating the flash mode is selected to display information on the category. When a user wishes to know the set values or advices about setting of the categories indicated by the icons in the screen image illustrated in  FIG. 7 , the user pushes the MENU key SW 9  for a relatively long period of time so that the image displayed in the LCD monitor  10  is changed to the image (i.e., an information displaying icon selection screen image of the digital camera) illustrated in  FIG. 8 . The method for the icon selection is not limited thereto, and the icon selection may be performed by a method of pushing a special button provided on the digital camera or another method. 
         [0054]    In the icon selection screen image illustrated in  FIG. 8 , the flash mode icon  30  is surrounded by a frame  32 . In this regard, at a time in which the image displayed in the LCD monitor  10  is changed to the icon selection screen image, the frame  32  surrounds an uppermost and leftmost icon. The position of the frame  32  can be changed by operating the four-direction keys SW 7 , SW 8 , SW 10  and SW 11 . When the MENU key SW 9  is pushed in the information displaying icon selection screen image illustrated in  FIG. 8 , the screen is returned to the still image shooting mode screen image illustrated in  FIG. 7 . When the OK key SW 12  is pushed in the icon selection screen image illustrated in  FIG. 8 , the screen image is changed to a screen image displaying information on the category indicated by the icon surrounded by the frame  32 . The data of each icon information displaying screen image are fixed and stored in the ROM  108 . 
         [0055]      FIGS. 9A and 9B  illustrate examples of the icon information displaying screen image. In  FIGS. 9A and 9B , reference numeral  34  denotes the name of the category of the selected icon, i.e., one of the names of the categories listed in  FIG. 6B , and reference numeral  35  denotes a table showing information on the selected category such as comments on kinds of the icons belonging to the category, names of the icons, set values, and setting methods. Thus, the information on the selected icon is displayed in the LCD monitor  10 . 
         [0056]    When the OK key SW 12  is pushed while the flash mode category icon  30  is surrounded by the frame  32  in the information displaying icon selection screen image illustrated in  FIG. 8 , a screen image illustrated in  FIG. 9A , which is the flash mode category icon information displaying image stored in the ROM  108 , is displayed in the LCD monitor  10 . When the OK key SW 12  is pushed while another category icon is surrounded by the frame  32  in the information displaying icon selection screen image illustrated in  FIG. 8 , the corresponding category icon information displaying screen image stored in the ROM  108  is displayed in the LCD monitor  10 . 
         [0057]    In the screen image illustrated in  FIG. 9A  in which the information on the flash mode category icon is displayed, “kinds of flash modes” are illustrated at an upper portion of the screen. In addition, several flash mode icons are illustrated in the first row of the table  35 , meanings of the icons are described in the second row of the table, and details of the icons and advices are described in the third row of the table. 
         [0058]    In the flash mode category icon information screen image illustrated in  FIG. 9A , the first column (i.e., “NO FLASHLIGHT” column) is surrounded by a frame  36 . This is because the flash mode category icon in the still image shooting mode screen image illustrated in  FIG. 7  is the “NO FLASHLIGHT” icon, i.e., the flash mode is set to the “NO FLASHLIGHT” mode. If the flash mode is set to another mode (for example, a “FORCIBLE FLASHING” mode), the corresponding column (the fourth (“FORCIBLE FLASHING”) column) of the table  35  in the screen image illustrated in  FIG. 9A  is surrounded by the frame  36 . Since the information on the set flash mode (for example, “NO FLASHLIGHT” mode) is stored in the RAM  107 , the column of the table  35  corresponding to the set flash mode (“NO FLASHLIGHT” mode column) is surrounded by the frame  36  by reference to the information. The frame  36  can be moved to another column of the table  35  by operating the up-and-down keys SW 7  and SW 10 . 
         [0059]    In the flash mode category icon information screen image illustrated in  FIG. 9A , when the MENU key SW 9  is pushed, the screen is changed to the icon selection screen image illustrated in  FIG. 8 . If the OK key SW 12  is pushed in the flash mode category icon information screen image illustrated in  FIG. 9A , the flash mode is changed so as to be set to the flash mode surrounded by the frame  36 , and then the screen image is changed to the icon selection screen image illustrated in  FIG. 8 . 
         [0060]    When shooting is performed while the object receives backlight, the user can notice the comments in the second column (AUTO mode) of the table  35  such that flash is emitted when the object is dark or receives backlight. Therefore, the user can set the flash mode to the “AUTO” mode without question. 
         [0061]    In the icon selection screen image illustrated in  FIG. 8 , the category can be changed from the category surrounded by the frame  32  (i.e., the flash mode category in  FIG. 8 ) to a battery level category by moving the frame to the battery mark icon  37  by operating the four-direction keys SW 7 , SW 8 , SW 10  and SW 11 , followed by pushing the OK key SW 12 . In this case, the screen image illustrated in  FIG. 8  is changed to the battery level information displaying screen image illustrated in  FIG. 9B . 
         [0062]    In the battery level information displaying screen image illustrated in  FIG. 9B , the name  34  of the category, “BATTERY LEVEL”, is displayed on an upper portion of the screen image. In addition, several battery level icons indicating different battery levels are illustrated in the first row of the table  35  in the screen illustrated in  FIG. 9B , and details of the icons and advices are described in the second row of the table. 
         [0063]    In the battery level information displaying screen image illustrated in  FIG. 9B , the first column is surrounded by the frame  36 . This means that the battery level of the digital camera is high. When the battery level is different from the high level, the corresponding battery mark icon is surrounded by the frame  36 . The information on the battery level is stored in the RAM  107  while updated. By reference to the information, the corresponding battery level icon is surrounded by the frame  36  in the screen image illustrated in  FIG. 9B . Unlike the flash mode screen image illustrated in  FIG. 9A , the frame  36  cannot be moved by operating the keys SW 7 , SW 8 , SW 10  and SW 11  in the battery level information displaying screen image illustrated in  FIG. 9B . 
         [0064]    By selecting one of the icons in the icon selection screen image illustrated in  FIG. 8 , the image can be changed to another screen image, which is predetermined and is stored in the ROM  108 . Whether or not the frame  36  can be moved in the icon information displaying screen image illustrated in  FIGS. 9A and 9B  is predetermined depending on the data stored in the ROM  108 . 
         [0065]    In the battery level information displaying screen image illustrated in  FIG. 9B , when the MENU key SW 9  is pushed, the screen image is changed to the icon selection screen image illustrated in  FIG. 8 . In this regard, it is possible that, by pushing the MENU key SW 12  or the OK key SW 12  in the screen image illustrated in  FIG. 9A  or  9 B, the screen image is changed to the still image shooting mode screen image illustrated in  FIG. 7 . 
         [0066]    Additional modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims the invention may be practiced other than as specifically described herein. 
         [0067]    This document claims priority and contains subject matter related to Japanese Patent Application No. 2009-275607, filed on Dec. 3, 2009, the entire contents of which are herein incorporated by reference.
