An image processor includes an extracting unit, an assigning unit, and an output unit. The extracting unit extracts at least one set of frame image data from the plurality of sets of frame image data included in one of the at least one set of moving image data. The assigning unit assigns a set of control data to each of the at least one set of frame image data extracted by the extracting unit. The output unit outputs an image list including a moving image index, the moving image index having an index frame image and information with respect to the set of control data, the index frame image being either one of a frame image corresponding to the at least one set of frame image data assigned with the set of control data and a resized frame image resized from the frame image.
