  According to the present invention, since the image of the operation member of the connected camera is displayed as the operation image, the user can operate the image management apparatus using the user interface of the camera familiar to the user, There is no need to learn how to operate the image management device.

  FIG. 1 is a block diagram showing a configuration of an embodiment of an image management apparatus according to this embodiment. For example, a photo storager is used as the image management apparatus 100. A photo storage device is a device that stores image data captured by a camera, and a user can display and view images stored in the photo storage device on a monitor or store them in the photo storage device. It is possible to instruct execution of various image processing on the obtained image. The photo storage device generally has an operation screen unique to each model, that is, a user interface, and the user can give various instructions to the photo storage device on the operation screen.

  The photo storage device according to the present embodiment, that is, the image management apparatus 100 has a unique operation screen in the same way as a general photo storage device, and the user operates using this operation screen. However, in order to further improve the convenience for the user, as will be described later, the user interface provided in the camera connected to the image management apparatus 100 is displayed on the monitor, so that the user is familiar with the camera. The image management apparatus 100 can be operated using the user interface.

  The image management apparatus 100 includes an input device 101, an external interface 102, a control device 103, an HDD 104, and a monitor 105.

  The input device 101 is, for example, an operation remote controller (remote controller), and buttons (keys) necessary for operating the image management apparatus 100 are arranged on the remote controller. The user can issue various instructions to the image management apparatus 100 by operating the remote controller.

  The camera interface 102 is an interface for connecting a camera (digital camera) by wire or wireless, such as a USB interface or a wireless LAN module. When the connection between the camera and the external interface 102 is established, the camera connected to the external interface 102 transmits the model information of the camera via the external interface 102. Upon receiving the camera model information from the camera, the camera interface 102 outputs a signal including the model information to the control device 103 as a signal indicating that the camera is connected (camera connection signal).

  Further, the external interface 102 captures a still image file or a moving image file (image file) from the camera in accordance with an instruction from the user. The image file captured via the external interface 102 is output to the control device 103 and recorded on the HDD 104 by the control device 103. The HDD 104 is a hard disk drive for recording an image file taken in via the external interface 102 and various programs for operating the image search apparatus 100. The monitor 105 is a liquid crystal monitor, for example.

  The control device 103 includes a CPU, a memory, and other peripheral circuits, and functionally includes a camera detection unit 103a, an operation screen display unit 103b, a process execution unit 103c, and a setting unit 103d.

  The camera detection unit 103 a detects that a camera is connected to the image management apparatus 100 when the camera connection signal described above is input from the external interface 102. Then, based on the camera model information included in the camera connection signal, the model of the connected camera is determined.

  Here, in the image management apparatus 100 according to the present embodiment, user interface information for each camera model is registered in the HDD 104 in advance. The user interface information for each camera model is information indicating a user interface that differs depending on the camera model, for example, image data representing various operation members (operation buttons) arranged on the back of the camera while maintaining the positional relationship. And a program in which each operation member is assigned a process actually assigned on the camera.

  That is, for each camera model, an image of the surface including the operation member (operation member image) and program emulation information are recorded in the HDD 104 as user interface information for each camera model. In a general camera, a liquid crystal monitor for displaying menu information and images is mounted on a surface having an operation member, for example, on the back surface of the camera, and thus image data registered as user interface information. Is image data representing each operation member and the liquid crystal monitor arranged on the back side of the camera while maintaining the positional relationship.

  The operation screen display unit 103 b reads user interface information corresponding to the camera model determined by the camera detection unit 103 from the HDD 104. Then, the operation screen is displayed on the monitor 105 by displaying the image of the camera operation member included in the read user interface information, for example, the image data of the rear surface of the camera on the monitor 105. That is, the image of the surface provided with the connected camera operation member is displayed on the monitor 105 while maintaining the positional relationship between the operation members and the liquid crystal monitor.

  For example, as shown in FIG. 2, the operation screen display unit 103b displays various setting buttons such as a menu button and a cross button provided on the back surface of the camera 2a and an operation screen displaying a liquid crystal monitor on the monitor 105. To do. In other words, an operation screen including a plurality of button areas corresponding to various operation buttons mounted on the back surface of the camera 2a and a monitor area 2c corresponding to a liquid crystal monitor is displayed on the monitor 105. Then, the user can use the input device 101 to operate the cursor 2b displayed on the operation screen and select an arbitrary button area included in the operation screen.

  When the input device 101 is operated by the user and any button area in the operation screen is selected by the cursor 2b, the process execution unit 103c operates the operation member of the camera 2a corresponding to the selected button area. The process assigned to is executed.

  For example, when the user selects a button area corresponding to a menu button in the operation screen and the camera 2a is assigned a process for displaying the menu screen on the liquid crystal monitor, the process execution unit 103c. Displays the same menu screen as that displayed on the liquid crystal monitor of the camera in the monitor area 2c in the operation screen. When the user operates the input device 101 and selects a button area corresponding to a playback button for instructing playback of an image on the operation screen, the process execution unit 103c is recorded in the HDD 104. The read image is read and the read image is displayed in the monitor area 2c.

  When the user operates the input device 101 and selects a button area corresponding to a delete button for instructing deletion of an image on the operation screen, the process execution unit 103c is recorded in the HDD 104. Delete the image. At this time, when an image is deleted on the camera side, if a function for displaying a deletion confirmation message is implemented on the liquid crystal monitor, the function is also reproduced on the operation screen. For example, on the connected camera, when a delete confirmation message such as “Are you sure you want to delete?” Is displayed on the LCD monitor when the delete button is pressed, the process execution unit 103c A similar deletion confirmation message is displayed in the monitor area 2c on the operation screen.

  As a result, the user can operate the image management apparatus 100 using the same user interface as the camera that he / she is familiar with, and it is not necessary to newly learn the operation of the image management apparatus 100.

  The operation screen display unit 103b also operates when the input device 101 is operated by the user and the cursor moves on the monitor area 2c, that is, when it is detected that the cursor hits the monitor area 2c. Is enlarged and displayed while maintaining the positional relationship with other button areas. As a result, when an image is displayed on the monitor area 2c by the user instructing the reproduction of the image on the operation screen, the user wants to enlarge and view the image on the monitor 105. The monitor area 2c can be enlarged simply by moving the cursor on the monitor area 2c, and the convenience of the user can be improved. Further, when enlarging the monitor area 2c, by maintaining the positional relationship between the monitor area 2c and the other button areas, it is possible to enlarge and display the image while maintaining the user interface of the camera.

  A specific example of the monitor area expansion is shown in FIG. When the user operates the input device 101 to move the cursor 2b onto the monitor area 2c on the operation screen that reproduces the rear part of the camera shown in FIG. 3A, the operation screen display unit 103b. As shown in FIG. 3B, the monitor area 2c is enlarged in the operation screen while maintaining the positional relationship between the monitor area 2c and the other button areas. Thereafter, when the user operates the input device 101 to place the cursor 2b on the enlarged monitor area 2c, the operation screen display unit 103b further displays the monitor area 2c in an enlarged manner as shown in FIG. To do. Here, the monitor area 2c shows an example in which the enlargement ratio is changed in two stages as shown in FIGS. 3B and 3C, but the enlargement ratio may be changed in three stages or more.

  When the camera is connected to the camera interface 102 and the setting menu is changed by the user operating the setting menu on the operation screen displayed on the monitor 105, the setting unit 103d changes the setting. The contents are output to the camera via the camera interface 102, and the camera settings are the same as those set on the operation screen.

  The setting unit 103d monitors the setting change status of the camera connected via the camera interface 102, and when the setting of the camera is changed by operating the operation member on the camera side, the camera interface 102 is displayed. The change contents of the setting are acquired from the camera, and reflected in the setting contents on the image management apparatus 100 side. That is, the setting of the camera set on the operation screen and the setting of the camera connected to the camera interface 102 are synchronized.

  In this way, by reflecting the operation on the operation screen displayed on the monitor 105 to the camera, the user can set the camera on the large operation screen displayed on the monitor 105 and perform the operation. It can be done easily. Further, by reflecting the operation on the camera side to the image management apparatus 100, the user can operate the image management apparatus 100 using a camera that he / she is familiar with instead of the remote controller, and convenience is improved.

  When the connection of the camera connected to the camera interface 102 is released, the camera detection unit 103a enters a standby state, and monitors whether the camera is connected to the camera interface 102 again. At this time, the operation screen display unit 103b continues to display the operation screen of the camera connected immediately before, and uses the user interface of the camera to which the user has been connected so far, to display the image management apparatus 100. Be ready to operate. The process execution unit 103c also executes the same process as that of the camera connected immediately before based on an operation by the user on the operation screen.

  When the camera setting is changed on the operation screen with the camera disconnected, the setting unit 103d stores the changed setting information in association with the camera model information in the HDD 104. deep. Next time, when a camera of the same model is connected to the camera interface 102, the stored setting information is output to the camera for synchronization.

  Thus, even after the connection between the camera interface 102 and the camera is released, the user can operate the image management apparatus 100 using the same user interface as that of the camera connected so far. In addition, the contents set on the operation screen after the camera is removed can be automatically reflected on the camera when the camera is connected the next time, improving the convenience for the user.

  On the other hand, when the end of the process is instructed by the user closing the operation screen or the like, each unit 103b to 103d ends the above-described process. Then, the camera detection unit 103a monitors the connection of the camera to the camera interface 102. When the user connects the camera to the camera interface 102 again, each unit 103b to 103d executes the above-described processing according to the model of the connected camera.
