Displaying halftone images using a spatial light modulator and a modulated light source

摘要

Gradations are displayed using an image display device (1) having a plurality of on-off type spacial light modulating elements (2), such as microscopic mirror elements, arranged according to pixels of image data. To display gradations using the on-off type spacial light modulating elements (2), a light source (6) whose light intensity can be modulated, or modulating means (7) for modifying the intensity of light from the light source, is utilized, and the gradations are displayed by performing light intensity modulation of the light from the light source (6) in accordance with the gradation for each pixel of the image data.
