Abstract: (Problem) To facilitate setting of an image display style and selection of images in an image display apparatus with a touch screen. (Solution to Problem) Thumbnails included in an area designated by a pinch gesture are all specified. If it is not true that “the thumbnails included in the designated area are all displayed in the selected style” (S2004, No), the thumbnails included in the designated area are all displayed in the selected style (S2005), and the status is set to selected state (S2006). If it is true that “the thumbnails included in the designated area are all displayed in the selected style” (S2004, Yes), the thumbnails included in the designated area are all displayed in unselected style (S2007), and the status is set to unselected state (S2008). If the gesture is continuously changed to a pinch-out gesture or a pinch-in gesture (S2010, No), the selected area or the unselected area are expanded or reduced depending on the status (S2014, S2015).

Abstract: An image processing device includes an input unit, a selection unit, a matching unit, an estimation unit and a merging unit. The input unit sequentially inputs images. The selection unit selects a reference image from among the input images. The matching unit calculates a correspondence relationship between a feature point of the reference image and a feature point of a target image. The estimation unit estimates an equation that causes a coordinate system of the reference image to correspond to a coordinate system of the target image using positional information of a pair of the feature points whose correspondence relationship has been calculated by the matching unit by regarding a motion between the reference image and the target image as only a rotational motion of the imaging element. The merging unit merges the input image and the target image to generate the composite image based on the equation.
