Claim 2:
3. The camera device according to claim 2, wherein the image controller includes:
a shift calculation unit configured to calculate 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;
a comparison unit configured to compare the actual shift value calculated by the shift calculation unit with the preset shift value; and
a correction unit configured to perform a correction when a difference between the actual shift value calculated by the shift calculation unit and the preset shift value is greater than or equal to a threshold value as a comparison result of the comparison unit.
