According to the invention, extracting still and moving pictures having different aspect ratios from an original picture from within an extraction range suitable for an imaging mode can be performed. An embodiment of the invention, according to the selected imaging mode, sets the still picture extraction range with an aspect ratio of 4:3 for extracting a still picture and the moving picture extraction range with an aspect ratio of 16:9 for extracting an HD moving picture within the imaging range of the imaging device 17. Then, the embodiment, from the imaged picture, extracts a picture within the set still picture extraction range as still picture, and extracts a picture within the set moving picture extraction range as HD moving picture. That is, the embodiment can switch between the still picture extraction range and the HD moving picture extraction range having different aspect ratios according to the imaging mode. And thus, from the picture within the imaging range (i.e., the original picture), the embodiment can extract the still picture and the HD moving picture having different aspect ratios from within the extraction range suitable for the imaging mode.
