In this detection, for example, color information, luminance values, and the like are acquired from image information, and information that is substantially the same as the acquired color information or included in a predetermined range is used as image information related to the same or substantially the same image. This is done by detecting. More specifically, the average value of color information (or other statistics) may be acquired from the image information, and the average value of the acquired color information may be the same or included in a predetermined range. Alternatively, it is performed by detecting image information relating to substantially the same image. Note that the image information when acquiring the color information may be image information related to one image, or may be image information related to one or more predetermined regions in one image.

  Subsequently, the image information related to the same or substantially the same image detected in S2 is grouped for each image information having consecutive frame numbers, that is, for each image information continuing in time series (S3). The frame number is attached to the image information in time series based on the imaging date and time. In this embodiment, the frame number becomes smaller as the imaging date is older, and the frame number becomes smaller as the imaging date is newer. It is getting bigger.

  Subsequently, in each of the groups grouped in S3, one piece of image information is selected from image information belonging to the group according to a predetermined condition, and thumbnail image information is created from the selected image information ( S4). The predetermined condition is a condition for selecting one piece of image information from one or a plurality of pieces of image information belonging to the group. For example, the frame number is selected from the image information belonging to the group. The condition is that the smallest or largest image information is selected.

  In S4, the selected image information is associated with the created thumbnail image information, and the corresponding image information can be specified later from the thumbnail image information. In this association, the image related to the selected image information is the original image of the thumbnail image related to the thumbnail image information.

  Subsequently, thumbnail images relating to the thumbnail image information of each group created in S4 are displayed in a time-series list on the display 7b (display unit 18) (S5).
