Claim 11:
12. The method according to claim 11, further comprising:
if the light emission time is shorter than a reference value, at least one of
calculating the fourth correction coefficient so that the light output corrected by the fourth correction coefficient becomes smaller than the light output when corrected by the third correction coefficient for a light emitting point where the light output when corrected by the third correction coefficient is larger than the light output when corrected by the first correction coefficient; and
calculating the fourth correction coefficient so that the light output corrected by the fourth correction coefficient becomes larger than the light output when corrected by the third correction coefficient for a light emitting point where the light output when corrected by the third correction coefficient is smaller than the light output when corrected by the first correction coefficient.
