ABSTRACT:
A display driving apparatus, which can automatically optimize a visual state in accordance with a temperature in a photographing operation, a photographing attitude of a user, and a user's preference, is disclosed. The apparatus may include an electro-optical display unit, a temperature detection unit for detecting an ambient temperature of the electro-optical display unit, and generating a temperature detection signal, a bias value generation unit for generating a bias value to the electro-optical display unit, a changing unit for changing the bias value, a storage unit for storing a plurality of bias values changed by the changing unit in correspondence with the temperature detection signals, and a bias value control unit for executing statistical processing of the plurality of bias values stored in the storage unit, and controlling the bias value generation unit on the basis of the processing result.
