A light amount correcting method for a light emitting apparatus having a plurality of light emitting devices driven according to grayscale value of input data, includes: measuring light amount values of a plurality of the light emitting devices when emitting light with predetermined grayscale values to generate a light amount value list; extracting high frequency components from the light amount value list by filtering the light amount value list with a high pass filter using a predetermined cutoff frequency to generate a high frequency light amount value list; extracting low frequency components from the light amount value list by filtering the light amount value list with a low pass filter using a predetermined cutoff frequency to generate a low frequency light amount value list; calculating first correction values for correcting the light amount values in the high frequency light amount value list to be included in a predetermined first allowable range and second correction value for correcting the light amount values in the low frequency light amount value list to be included in a predetermined second allowable range and calculating correction values for a plurality of the light emitting devices based on the first and second correction values; and correcting grayscale values of the input data for a plurality of the light emitting devices based on the correction values.
