PROBLEM TO BE SOLVED: To compute a correction value for accurately correcting an error of a visual axis caused by the individual difference of a subject.SOLUTION: A correction value computing device 101 acquires a plurality of pairs of temporary visual axis positions VP and points of gaze G on a display image SP, and then, statistically acquires a correction value intrinsic to a subject 120. In this case, the correction value computing device 101 acquires the pair of the temporary visual axis position VP and the point of gaze G for each divided section obtained by dividing the display image SP on a screen 105. The correction value computing device 101 computes the correction value intrinsic to the subject 120, based on the pairs of the multiple sections. Thus, it is prevented that the pairs to be the computation source of the correction value intrinsic to the subject 120 are biased to the specific section, thereby to correctly acquire the correction value intrinsic to the subject 120.
