INFORMATION PROCESSOR AND INFORMATION PROCESSING METHOD

摘要

An image storage section 48 stores shot image data with a plurality of resolutions transmitted from an imaging device. Depth images 152 with a plurality of resolutions are generated using stereo images with a plurality of resolution levels from the shot image data (S10). Next, template matching is performed using a reference template image 154 that represents a desired shape and size, thus extracting a candidate area for a target picture having the shape and size for each distance range associated with one of the resolutions (S12). A more detailed analysis is performed on the extracted candidate areas using the shot image stored in the image storage section 48 (S14). In some cases, a further image analysis is performed based on the analysis result using a shot image with a higher resolution level (S16a and S16b).

主权项

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.
