In FIG. 3, when the imaging function of the imaging unit 2 is activated by the main control unit 10, the main control unit 10 then communicates with the connection interface unit 12 and the external memory 3 is mounted on the apparatus main body 1. It is determined whether or not it is in the state (S301).
Here, when it is determined that the external memory 3 is mounted and shooting by the imaging unit 2 is performed (S302), the video signal captured and acquired by the imaging unit 2 is output to the image data generation unit 11. The

  The image data generation unit 11 generates image data compliant with the DCF format from the video signal, outputs the image data to the external memory 3 via the connection interface unit 12, and further outputs the image data to the related data generation unit 13. I also do. The external memory 3 stores the output image data (S303), and the related data generation unit 13 generates a thumbnail image based on the output image data and stores the thumbnail image and the external image in the external memory 3. In order to associate with the image data, the file name given to the thumbnail image is acquired, the external memory 3 is referred to via the connection interface unit 12, the serial number and the storage hierarchy of the external memory 3 are acquired, An index table whose example is shown in FIG. 2 is generated (S304, S305) and output to the related data storage unit 15 (S306).

  In step S301, when it is determined that the external memory 3 is not mounted and shooting by the imaging unit 2 is performed (S307), the image data is stored in the internal memory 14 (S308), and thereafter The process proceeds to step S304 described above, and the same operation is performed until step S306.

The flowchart of FIG. 4 shows a process for calling image data stored in the internal memory 14 or the external memory 3 as described above.
First, the main control unit 10 controls the display control unit 16 to display thumbnail images (first related data and second related data) stored in the related data storage unit 15 on the display unit 4 and select instructions to the user. Prompt. FIG. 6A is a conceptual diagram showing this state. In this figure, a total of nine thumbnail images (1) to (9) are displayed. These thumbnail images are thumbnail images (1) to (1) as first related data (related data stored in the internal memory 14). (4) and thumbnail images (5) to (9) as second related data (related data stored in the external memory 3). The user selects and inputs a thumbnail image for which high-quality data is to be displayed from the thumbnail images displayed on the display unit 4 by operating the operation input unit 5 (S401). The information selected and input here is taken into the main control unit 10 via the input data acquisition unit 17. Here, it is assumed that the thumbnail image (1) is selected.

  Next, the index data stored in the related data storage unit 15 is referenced to search whether there is corresponding image data at the storage destination address (S402).

When the thumbnail image related to the image data stored in the external memory 3 is selected in the process of step S401, but it is determined that the external memory 3 is not connected, the main control unit 10 displays The controller 16 is controlled to perform irregular display (external memory 3 insertion instruction pop-up) as shown in FIG. 5A (S404).
In the process of step S402, when it is determined that there is no corresponding image data at the storage destination address, the main control unit 10 controls the display control unit 16 to display the image as shown in FIG. Regular display (pop-up indicating that there is no corresponding data) is performed (S405).

  When it is determined in step S402 that there is image data corresponding to the storage destination address, when the storage destination address exists in the internal memory 14, the main control unit 10 acquires the image data from the internal memory 14, and When present in the memory 3, the main control unit 10 further acquires image data from the external memory 3 via the connection interface unit 12 and supplies the image data to the display control unit 16. The display control unit 16 displays the image data on the display unit 4 (S403). FIG. 6B is a conceptual diagram showing this state. Here, the image data related to the thumbnail image (1) selected in step S401 is displayed on the display unit 4.

According to the above-described embodiment, image data shot by the shooting unit 2 is stored in the internal memory 14 or the external memory 3 such as a memory card, and a thumbnail image related to the image data is linked to the image data. Since the image data is also stored in the related data storage unit 15, the user can link the image data to the internal memory 14 or the external memory 3 and reproduce it by selecting the thumbnail image. That is, even a person who does not have a concept of storing captured data in the external memory 3 such as a beginner including a senior can easily check the stored data.
In addition, the sense of unity between the internal memory 14 (data folder) and the external memory 3 can be improved, and the high-quality data can be confirmed in time series in the data folder. As described above, it is possible to provide a display device that improves operability when displaying high-quality data and improves convenience.

  In addition, this invention is not restricted to the aspect of this embodiment, A change and application are possible suitably in the range which does not deviate from a technical range.

  For example, in the present embodiment, the thumbnail image is stored in the related data storage unit 15 and the image data stored in the internal memory 14 or the external memory 3 can be displayed based on the stored thumbnail image. However, the present invention is not limited to this. That is, even if there is no related data storage unit 15, a configuration is adopted in which thumbnail images are generated and stored in advance in the internal memory 14 or the external memory 3 (thumbnail image generation timing is, for example, when image data is stored), and the main control unit 10 However, the display control unit 16 may be controlled so that thumbnail images are displayed on the display unit 4 and the thumbnail images are simultaneously displayed on the display unit 4 when the user is prompted to select.

Alternatively, the thumbnail image is not generated in advance, and the control unit 10 displays the display control unit 1.
6 to display a thumbnail image on the display unit 4 and prompt the user to select,
The related data generation unit 13 may generate a thumbnail image of the image data stored in the internal memory 14 and the external memory 3 and then control the display unit 4 to display the generated thumbnail image.

In the present embodiment, the external memory 3 can display a list of thumbnail images on the display unit 4 regardless of whether the external memory 3 is connected to the connection interface 12, but the present invention is not limited to this. It is not something. For example, when the external memory 3 is not connected to the connection interface 12, only thumbnail images related to the image data stored in the external memory 3 may not be displayed at least in the list. Only thumbnail images related to the image data stored in the memory 14 may be displayed in the list. In this way, the thumbnail image related to the image data stored in the external memory 3 is displayed on the display unit 4, but the external memory 3 is not connected to the connection interface. image data it is possible to remove the adverse effect was Tsu trough that can not be either be read out.

However, even when the external memory 3 is not connected to the connection interface 12 as described above, a thumbnail image related to the image data stored in the external memory 3 may also be displayed. In this way, the user can obtain an effect that at least the thumbnail images stored in the related data storage unit 15 can be browsed regardless of the connection state (actually, in the present embodiment, this is the case. It is like this).

  In the present embodiment, both thumbnail images and index data generated by the related data generation unit 13 are generated based on image data captured by the imaging unit 2, but the present invention Is not limited to this. That is, for example, images other than the image data photographed by the photographing unit 2 such as image data photographed and stored by other cameras, image data transferred via other devices, or via a network. Even for data, the related data generation unit 13 may generate thumbnail images and index data of such image data and store them in the related data storage unit 15 under the control of the main control unit 10. . In this way, even image data other than the image data photographed by the photographing unit 2 can be displayed on the display unit 4 based on the thumbnail image and the index data, thereby improving operability and convenience. be able to.

In the configuration of the related data generation unit 13 in the present embodiment, part or all of the image data stored in the internal memory 14 is the same as part or all of the image data stored in the external memory 3. Even in such a case, the thumbnail image and the index data related to both image data can be displayed on the display unit 4 respectively. However, when both the image data relate to the same, only one of the images is displayed. Only thumbnail images and index data related to data may be generated. By doing so, it is possible to prevent duplicate thumbnail images and index data from being generated and stored, to reduce the capacity of the related data storage unit 15, and to improve operability and convenience. Can do. The identity determination of the image data may be performed based on information such as the shooting date / time and the data size included in the image data.

  In addition to the removable flash memory such as a memory card, the external memory may be a floppy disk (registered trademark), an external hard disk, or a server on the network. Any storage medium that can switch the connection state may be used.

In the present embodiment, image data has been described as an example of the first data and the second data. However, the first data and the second data in the present invention are not limited to such image data, for example, music data. There may be other data such as movie data. In short, these data are stored in the internal memory 14 or the external memory 3, and then the reduced data display section 4 is stored.
It is sufficient that the user can browse, play back, and operate based on the display after the list is displayed.

  Moreover, according to the above-described embodiment, the display device used for the mobile phone terminal is exemplified as the display device. However, the display device is not limited to the mobile phone terminal, and the display of the digital camera or the device equipped with the digital camera is displayed.
