Abstract
A signal processing device that generates an output signal from image data by using a clock corresponding to the pixels of the image data, the signal processing device includes: a delayed signal group generating unit that generates a group of delayed signals with a delay element group formed with stages of delay elements; a clock adjusting unit that generates a modulation/synchronization clock from the group of delayed signals by referring to phase data matching the clock with a predetermined phase and frequency modulation coefficient data converting the clock to a predetermined frequency; and a PWM processing unit that generates a PWM signal from the group of delayed signals by referring to the phase data, the frequency modulation coefficient data, the modulation/synchronization clock, and the image data, the PWM signal having a pulse width corresponding to the value of the image data.
