Patent ID: 7079161

Claim:
An image display apparatus, comprising: an image-forming device that is arranged in a matrix, driven via a plurality of row and column wirings, and used to form an image; a scan unit that sequentially selects and scans said row wiring; an adjusted image data calculation unit that calculates adjusted image data for decreasing an influence of a voltage drop resulting from at least the resistance component of said row wiring for image data; and a modulator that outputs a modulation signal applied to said column wiring based on said adjusted image data, wherein said adjusted image data calculation unit comprises a discrete adjusted image data calculation unit that sets a plurality of discrete image data reference values for image data and calculates discrete adjusted image data for said image data reference value, and an adjusted image data interpolation unit that interpolates the output of the discrete adjusted image data calculation unit and adjusted image data that corresponds to the size of the image data, wherein said discrete adjusted image data calculation unit splits the one horizontal scan interval into a plurality of time areas corresponding to said image data reference value, expands the respective time areas so that the total amount of the emission brightness amount emitted in the respective time areas can be made equal when no influence of the voltage drop takes place, integrates an expanded result of the respective time areas, and calculates said discrete adjusted image data.
