1. An information processor comprising: a candidate area extraction section adapted to extract a candidate area in which a target picture is likely to exist in a shot image by performing template matching on a depth image using a template image, the depth image representing, on an image plane, a distance of a subject from a camera in a depth direction as a pixel value, the template image representing a shape and a size of the target to be analyzed; a detailed information acquisition section adapted to analyze the shot image using information relating to the candidate area extracted by the candidate area extraction section; and an output information generation section adapted to generate output information based on results of image analysis performed by the detailed information acquisition section and output the output information.
