<P>PROBLEM TO BE SOLVED: To provide a surface light source control device capable of executing accurate light quantity control. <P>SOLUTION: This surface light source control device controls emission quantities of a plurality of light emitting parts arranged in a surface light source. Each of the plurality of light emitting parts includes a plurality of light emitting elements, and an optical sensor. The surface light source control device is provided with: a plurality of first control means for respectively controlling light quantities emitted from the plurality of light emitting parts in response to a timing direction; and a second control means for causing the plurality of first control means to control the light quantities nearly at the same time by respectively outputting the plurality of timing directions to the plurality of first control means nearly at the same time. <P>COPYRIGHT: (C)2007,JPO&INPIT |
