Abstract
An eye tracking device according to the present disclosed technology includes: an image acquiring unit that acquires an image of a subject; an arithmetic processing unit that performs image processing; and a line-of-sight angle calculating unit that calculates a line-of-sight direction vector on the basis of a result of the image processing. The arithmetic processing unit includes: a real image arithmetic processing unit that performs arithmetic processing on a real image in an image space; and a three-dimensional model superimposition processing unit that performs superimposition processing on the image space using a three-dimensional face model. The three-dimensional model superimposition processing unit includes a three-dimensional model correcting unit that corrects the three-dimensional face model in order to eliminate an error caused by the superimposition processing.
