Abstract
A video clock generation apparatus and method are provided. The apparatus comprises a ring oscillator for generating an oscillation frequency; a loopspeed detection unit for detecting a loopspeed that represents the number of pulses generated at the oscillation frequency when the ring oscillator oscillates for a predetermined time; and a video clock generation unit for suppressing generation of front-end video clock signals for a predetermined initial time, and after a first predetermined time following initialization of the effective video clock signals, maintaining a clock state of back-end video clock signals for a second predetermined time, wherein the front-end video clock signals precede effective video clock signals for image formation and the back-end video clock signals follow the effective video clock signals, and wherein the maintained clock state is the clock state prior to the second predetermined time clock signals.
