Abstract
A pixel clock generator device includes a high frequency clock generator, a phase shift data generator to generate phase shift data for controlling a phase shift amount of a pixel clock, a phase shift data pattern generator to read the phase shift data from the phase shift data generator, generate a pattern of the phase shift data for output, and when outputting a same phase shift data pattern for consecutive scan lines, generate, for a next scan line, a phase shift data pattern in which a pixel clock at a position moved by a random number of pixel clocks from a phase-shift position of a pixel clock in a phase shift data pattern for a current scan line is phase-shifted, and a pixel clock generator to generate, on the basis of a high frequency clock, a pixel clock phase-shifted in accordance with the generated phase shift data pattern.
