Patent ID: 7280125

Claim:
An image display apparatus, comprising: multiple image-forming devices connected to multiple row lines and column lines and disposed in the form of a matrix; scanning means connected to the row lines; modulating means connected to the column lines; image-forming members severally associated with the image-forming devices and having a nonlinear characteristic with respect to a driving condition of the image-forming devices; gradation converting means for converting a gradation characteristic of inputted image data in accordance with the characteristic of the image-forming members; compensated image data computing means for computing compensated image data by compensating the output of the gradation converting means for at least an effect of voltage drop arising due to resistance of the row lines; amplitude regulating means for applying a gain for regulating the amplitude of the compensated image data so that the amplitude of the compensated image data corresponds with an input range of the modulating means; and a scene change detecting portion for detecting a change of a scene displayed on the image display apparatus, wherein the gradation converting means performs a gradation conversion corresponding to the gain, the amplitude regulating means has filtering means for carrying out different filter processing in accordance with the output of the scene change detecting portion on the gain computed for each frame, the modulating means receives the compensated image data amplitude-regulated by the amplitude regulating means as input and outputs a modulating signal to the column lines, and the filtering means does not perform filter processing with respect to a predetermined frame immediately after a scene change is detected by the scene change detecting portion and operates as a low pass filter with respect to frames other than the predetermined frame immediately after the scene change is detected.
