Patent ID: 7385625

Claim:
A printer comprising: An exposing liquid crystal display unit having a transmissive liquid crystal panel having a number of pixels arranged on a two-dimensional basis, on which an image is formed, and a light source unit emitting beams of light of a plurality of luminescent colors for irradiating said liquid crystal panel from back; an interface circuit for separating an entered color image signal to a plurality of color image signals associated with a plurality of luminescent colors of said light source unit, respectively, to sequentially form on said liquid crystal panel a plurality of separation images associated with the plurality of color image signals, said interface circuit causing said light source unit to flash with a luminescent color associated with a separation image formed on said liquid crystal panel in synchronism with a sequential formation of the separation images onto said liquid crystal panel; and an exposing optical system for magnifying and projecting an image formed on said exposing liquid crystal display unit to provide imaging on a sensitive plane of a sensitive material.
