| 1. A beam light scanning device comprising:
an image data processor configured to output data of neighboring pixels while dividing for distribution the data into first
pixel data and second pixel data;
an adjuster device configured to perform specified adjustment with respect to the first pixel data and the second pixel data
as output from said image data processor;
a synthesis device configured to combine together the adjusted first and second pixel data as output from said adjuster device;
a light emission device responsive to receipt of the pixel data as output from said synthesis device configured to emit light
as a scan beam; and
a horizontal synchronous signal generator configured to generate a horizontal synchronous signal based on detection of pass-through
of the scan beam as emitted from said light emission device,
wherein said adjuster device includes a signal synchronizer to synchronize a reference clock signal based on the horizontal
synchronous signal as generated from said horizontal synchronous signal generator and to output the first and second pixel
data in synchronism with said reference clock signal thus synchronized.
