摘要： There is provided an ocular image capturing device comprising an ocular image generating module operable to generate an image of a subject's eye based on light reflected from the eye, and a determination module arranged to determine whether or not at least a portion of a pupil region of the generated image is within a predetermined permissible region within the generated image, and to generate a signal that is indicative of the determination, the pupil region being an image of at least a portion of the pupil of the eye.

摘要： A photographic subject tracking device includes: a first degree-of-similarity calculation unit that calculates degree of similarity between a template image for tracking and an image in search area; a photographic subject position identification unit that identifies a tracked photographic subject position in the input image based on calculated degree of similarity; a second degree-of-similarity calculation unit that calculates a degree of similarity between each of multiple template images for resizing determination, which are generated based on template image for tracking, and image in search area; a matching position identification unit that identifies matching positions of the multiple template images for resizing determination, respectively, in the input image based on calculated degrees of similarity; and a size changing unit that changes an image size of template image for tracking and template images for resizing determination based on a density of the plurality of matching positions identified.
