A tracking device for tracking a feature point in an image includes: a first calculation unit to calculate first values indicating degree of corner for respective pixels in another image, based on change of brightness values in horizontal direction and vertical direction; a second calculation unit to calculate second values indicating degree of similarity between respective areas in the another image and a reference area around the feature point in the image, based on comparison between the respective areas and the reference area; a third calculation unit to calculate third values indicating overall degree of corner and similarity, based on the first values and the second values; and a tracking unit to track the feature point by identifying a point in the another image corresponding to the feature point in the image, based on the third values. |
