摘要： A ring oscillator setting apparatus and method depending on an environmental change of an image formation apparatus is provided. The apparatus includes a plurality of ring oscillators for generating different oscillation frequencies. The apparatus further includes a loopspeed detection unit to detect a loopspeed representing the number of pulses generated at the oscillation frequency by one of the ring oscillators selected from the plurality of ring oscillators for a predetermined unit time. Moreover, a state sensing unit is provided to detect a state of system environment of the image formation apparatus. A setting control unit is also provided to select and set one of the ring oscillators selected corresponding to change of the loopspeed detected from the loopspeed detection unit among the plurality of ring oscillators in response to the detected state of the state sensing unit. Therefore, even when external environment changes such as temperature and voltage of the image formation apparatus change, the one of the ring oscillators selected having the optimal loopspeed to generate a video clock can be set. Therefore, it is possible to minimize degradation of image quality caused by environmental changes.
