Referring to FIG. 1B, the data obtained through the image pickup section 115a of the digital photographing apparatus has additional information on the image as well as the photographing time and the photographing condition for the image. The image file generating unit 182 generates an image file including such image and image information. The image information has additional information about the shooting time and shooting conditions for the image, and is stored as metadata in the image file. Metadata is data for data. It refers to the information that follows some data, that is, the data that follows the data to analyze and classify the structured information and add additional information. For example, in the digital photographing apparatus, every time a photograph is photographed and recorded, photograph information such as information of the digital photographing apparatus itself, time at the time of photographing, exposure, whether to use the flash, resolution, and photo size is stored together with image data. By analyzing these data, it becomes information that can be used very usefully when rearranging or rearranging the photographs properly. In recent years, using the GPS function, location information can be entered into the metadata of a photo, which can easily tell where the photo was taken, which can then be used to search other local information, It is possible to improve the searchability.

The display data deriving unit 186 may derive first display data from at least one stored image file and derive second display data from at least one stored image file. The first display driver 160 and the second display driver 170 may provide driving signals to the first display unit 165 and the second display unit 175 under the control of the display data deriving unit 186. [

The mode selection unit 184 is an image information display mode for displaying image information (for example, information data such as a shooting date and time, shooting conditions, and image capacity) when switching from the digital photography apparatus 100a to the image playback mode, A multi-image display mode for displaying a plurality of thumbnail images together with a representative image, and a single image display mode for displaying a second image together with the first image. It should be noted, however, that this mode selection may be pre-set by the user by default.

When the image information display mode is selected through the mode selection unit 184, the display data deriving unit 186 derives an image from any one of the image files as first display data, The image information (information data such as the shooting date and time, condition, and capacity) provided from the image file can be derived as the second display data. That is, in the image information display mode, the user can browse the image information on the photograph using a display unit different from the display unit on which the photograph is displayed, so that the user can browse the additional information on the photograph To provide a function.

When the multi-image display mode is selected through the mode selection unit 184, the display data deriving unit 186 derives a representative image from any one of the image files as first display data, As second display data, a plurality of thumbnail images provided from the first display data. A thumbnail image is a simple image that has a preview function with a full outline of the image. As described above, in the multi-image display mode, a multi-image having a selected image is divided into a first display section and a second divided display section (for example, 4, 9, 16 division, etc.) is reproduced. In other screens, the images can be viewed at a time, providing convenience to users.

When the single image display mode is selected through the mode selection unit 184, the display data deriving unit 186 derives the first image from any one of the image files as the first display data, Accordingly, a second image provided from an image file before or after the image file can be derived as second display data. That is, in the single image display mode, an image to be viewed is reproduced in one display portion and an image in front of or after the currently reproduced image is reproduced in the other display portion so that a continuous image can be previewed, It also provides a function to play back the pictures together.
