Abstract:
1. An image production apparatus, comprising: an optical light source providing a source of optical light; an optical modulation device for modulating light from said optical light source, said optical modulation section including a plurality of fixed electrodes and a plurality of displaceable electrodes positioned adjacent said fixed electrodes; a driving circuit for driving said optical modulation device in response to an input signal, said displaceable electrodes being displaced or deformed responsive to a driving signal applied to form offsets from said fixed electrodes; an initial driving signal production circuit for producing an initial driving signal for deriving said optical modulation device in response to the input signal; a spatial filter; and correction means for determining, from a target light intensity of modulated light to be emitted from said optical modulation device in response to the initial driving signal and an intensity of the modulated light emitted from said optical modulation device in response to the driving signal, a value of the driving signal for said optical modulation device corresponding to the target light intensity and inputting the determined driving signal to said driving circuit.
