Zusammenfassung:	An object tracking apparatus tracks an object on image data captured continuously. The object tracking apparatus includes an object color adjusting unit and a particle filter processing unit. The object color adjusting unit calculates tendency of color change in regions on image data and adjusts a color of the object set as an object color based on the tendency of color change to obtain a reference color. The particle filter processing unit estimates a region corresponding to the object on image data based on likelihood of each particle calculated by comparing a color around each particle with the reference color, using particles which move on image data according to a predefined rule.
