Abstract
Official abstract text for this publication.
This display includes a control portion controlling a laser beam generation portion to output a first laser beam including a region of relaxation oscillation to a partial first image forming element included in a plurality of image forming elements and to output a second laser beam including no region of relaxation oscillation to a second image forming element, other than the first image forming element, included in the plurality of image forming elements.
First claim
Opening claim text (preview).
What is claimed is: 1. A projector comprising: a laser beam generation portion outputting laser beams; a projection portion projecting an image formed by a plurality of image forming elements on an arbitrary projection region by scanning said projection region with said laser beams; and a control portion controlling said laser beam generation portion to output a first laser beam including a region of relaxation oscillation where the output of said laser beam is unstabilized in…
