<P>PROBLEM TO BE SOLVED: To synchronize a timing of a pixel signal given to each pixel with a clock signal in a drive circuit for driving an LCOS element at a high speed. <P>SOLUTION: The driving circuit of the LCOS element includes: a plurality of D/A converters 21-24 for effecting D/A conversion on image data which is fed to each pixel of the LCOS element on a pixel group-by-pixel group basis; and delay devices 26-29 for delaying clock signals to provide timing for each D/A conversion operation. The clocks to be fed to the respective D/A converters are delayed via the delay devices to cause variation in delay time, so that output pixel signals from the D/A converters 21-24 can be applied to the LCOS element in a synchronized state. This makes it possible to drive the LCOS element at high speed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
