Position information adding apparatus, position information adding method, and computer program for adding position information and position detection apparatus

摘要

A position information adding apparatus includes: a reference position setting unit which sets a plurality of reference positions for each of a plurality of pictures contained in digitalized video data; a region setting unit which sets a first position information adding region at a first position defined based on at least any of the plurality of reference positions and a second position information adding region at a second position different from the first position, for each of the plurality of pictures; and a position information embedding unit which embeds a first moving pattern which moves on the pictures in a first temporal period into the first position information adding region and a second moving pattern which moves on the pictures in a second temporal period into the second position information adding region.

1. A position information adding apparatus comprising:
a processor configured to set a plurality of reference positions for each of a plurality of pictures contained in digitalized video data; set a first position information adding region at a first position defined based on at least any of the plurality of reference positions and a second position information adding region at a second position different from the first position, for each of the plurality of pictures; and embed a first moving pattern which includes a cyclic pattern with a first pitch along a first direction and moves along the first direction with a first speed on the pictures in a first temporal period into the first position information adding region and a second moving pattern which includes a cyclic pattern with a second pitch along a second direction and moves along the second direction with a second speed on the pictures in a second temporal period into the second position information adding region.
