Claim 18:
19. The depth image generation method according to claim 18, wherein said acquiring depth information of the object includes:
calculating at least one of an actual shift value of the optical path of the input light signal in the first direction during the first period, an actual shift value of the optical path in the second direction during the second period, an actual shift value of the optical path in the third direction during the third period, and an actual shift value of the optical path in the fourth direction during the fourth period;
comparing the actual shift value calculated by said calculating with the preset shift value; and
performing a correction when the difference between the actual shift value calculated by said calculating and the preset shift value is greater than or equal to a threshold value as a comparison result of said comparing.
