Abstract
Abstract An identifying apparatus and method and a robot apparatus capable of reliably identifying other moving objects or other objects, a position detecting apparatus and method and a robot apparatus capable of accurately detecting the position of a moving object or itself within a region, and a color extracting apparatus capable of accurately extracting a desired color are difficult to be realized. Objects are provided with identifiers having different color patterns such that the color patterns are detected and identified through image processing. Also, the objects of interest are given color patterns different from each other, such that the position of the object can be detected by identifying the color pattern through image processing. Further, a plurality of wall surfaces having different colors are provided along the periphery of the region, such that the position of an object is detected on the basis of the colors of the wall surfaces through image processing. Further, a luminance level and color difference levels are sequentially detected for each of pixels to extract a color by determining whether or not the color difference levels are within a predetermined range.
