An image display method for scanning modulated lights emitted from a plurality of optical modulation devices, each of which includes a plurality of fixed electrodes and a plurality of displaceable electrodes positioned adjacent said fixed electrodes and individually displaced or deformed in response to a driving signal applied thereto to form offsets from said fixed electrodes so that illumination light from a light source incoming to one of faces of said fixed and displaceable electrodes is modulated in accordance with the offsets such that the modulated lights from said optical modulation devices are arrayed linearly to form a one-dimensional image, on a plane to display a two-dimensional image, comprising:
- a driving signal correction step of determining, before an image is displayed, from a target light intensity of the modulated lights emitted from said optical modulation devices in response to an initial driving signal produced from an input signal and intensities of the modulated lights emitted from said optical modulation devices in response to the driving signals, values of the driving signals for said optical modulation devices corresponding to the target light intensity;
- and
- a step of applying, when an image is to be displayed, the driving signals of the determined values to said optical modulation devices to drive said optical modulation elements.
