ABSTRACT:
A signal processing unit that generates data signals for controlling gray-scale levels of electro-optical elements includes a first D/A conversion unit that generates gray-scale signals from gray-scale data for designating the gray-scale levels of the electro-optical elements; a storage unit that stores correction data indicating correction values with respect to the gray-scale signals; a second D/A conversion unit that has resolution different from that of the first D/A conversion unit, and that generates correction signals from the correction data stored in the storage unit; and a synthesizing unit that synthesizes the gray-scale signals generated by the first D/A conversion unit with the correction signals generated by the second D/A conversion unit to generate the data signals.
