<P>PROBLEM TO BE SOLVED: To provide an image display device for displaying a high quality image without making a buffer memory for storing image data into the buffer memory having large capacity and capable of performing a high-speed processing. <P>SOLUTION: A laser projector 1 includes a frame buffer 25 storing image data for every color, and laser data buffers provided for every color of a laser beam and having a writing area for writing image data for one horizontal line and a reading area for storing the written image data for one horizonal line. Vertical and horizontal displacement of the laser beam on the face S onto which the laser beam is projected is corrected by transferring the image data for one horizontal line corresponding to the vertical displacement from the frame buffer 25 to the laser data buffer and making such adjustment as to drive the laser at the timing corresponding to the horizontal displacement on the basis of displacement information stored in a displacement information table 331. <P>COPYRIGHT: (C)2011,JPO&INPIT |
