发明名称 CODE PATTERN HAVING CROSS-SHAPED POSITIONING PATTERN AND IMAGE PROCESSING DEVICE FOR PROCESSING THE SAME
摘要 A code pattern having cross-shaped positioning patterns is disclosed, comprising: a plurality of marks, which at least include a central positioning mark, a first positioning mark, a second positioning mark, a third positioning mark, and a fourth positioning mark; the central and the first to fourth positioning marks are distributed in a region along with other marks. The first to fourth positioning marks are four neighboring marks that are closest to the central positioning mark in distance. In addition, The central and the first to fourth positioning marks are disposed in the shape of a cross within the region, and corresponding to a coordinate obtained by adding together four coordinates from the first to fourth positioning marks then dividing a resulted sum thereof by four, is equivalent to a coordinate corresponding to the central positioning mark.
