ABSTRACT:
A method for driving an optical deflecting device array is disclosed, including in a series of processes for the light deflection operation, at least, a state of a first stage writing and recording data for indicating an inclination direction of the plate member to incline in a first inclination direction or a second inclination direction, into a semiconductor memory device arranged immediately under or adjacent to each of the plurality of optical deflecting devices; a state of a second stage switching the inclination direction of the plate member of the arbitrary optical deflecting device to the first inclination direction based on an indication of the data, and deflecting light; and a state of a third stage switching the inclination direction of the plate member of the arbitrary optical deflecting device to the second inclination direction based on the indication of the data, and deflecting light.
