ABSTRACT:
The present invention discloses a clock signal generation circuit for generating one or more clock signals for performing a scanning operation by scanning a light beam from a light source to a scan target. The clock signal generation circuit includes a determination circuit for determining authenticity of start information in accordance with at least one of the length of the start information and the timing at which the start information is input, and a generation circuit for generating the clock signals in synchronization with the start information when the determination circuit determines that the start information is authentic.
