Abstract:
1. An image analysis apparatus for recognizing an object image included in a frame image, the object image including a reference cell having a predetermined shape and a plurality of corner cells assigned a color different from that of the reference cell, comprising: a binarization processor which sets up a range of pixel values in the RGB format so as to translate the frame image into a binary bit representation; a first detector which detects the reference cell in binary data for the frame image; and a second detector which detects the corner cells in the binary data for the frame image, wherein the binarization processor sets up a range of pixel values in the RGB format for detecting the reference cell and binarizes the frame image by extracting pixels within the range thus set up, whereupon the first detector detects the reference cell by referring to the resultant binary data, and the binarization processor sets up a range of pixel values in the RGB format for detecting the corner cells and binarizes the frame image by extracting pixels within the range thus set up, whereupon the second detector detects the corner cells by referring to the resultant binary data.
