Image process apparatus with hologram lenses arranged in a concentric form or a spiral form

An image processing apparatus comprising:

• a spatial light modulator;
• a digital reading system for digitally reading an image data written on said spatial light modulator by two-dimensionally moving a laser beam on said spatial light modulator for scanning;
• a processing unit for processing the read image data;
• and
• a digital writing system for digitally writing the processed image data on said spatial light modulator by two-dimensionally moving the laser beam on said spatial light modulator;
• wherein at least one of said digital reading and writing systems provides a hologram disk, the hologram disk having a plurality of hologram lenses located in at differing radial distances from a center of the hologram disk.
