Abstract:
1. An electronic endoscopic apparatus comprising: an endoscope; and an image processor, wherein the endoscope includes: the image processor includes: an imaging-side clock generating unit that generates an imaging-side clock; a second multiplying/dividing unit that multiplies and/or divide the imaging-side clock to generate the transmission clock; a display-side clock generating unit that generates a display-side clock; an imaging-side synchronization signal generating unit that generates an imaging-side synchronization signal in the image processor; a display-side synchronization signal generating unit that generates a display-side synchronization signal in the image processor based on the display-side clock; a phase comparing unit that compares a phase of the imaging-side synchronization signal with a phase of the display-side clock and control an oscillation of the display-side clock generating unit based on a result of the comparison; and a display timing adjusting unit that receives the video signal output from the endoscope at a timing based on the imaging-side synchronization signal and adjust a synchronization timing of the received video signal to a synchronization timing based on the display-side synchronization signal, and a frequency of the display-side clock is M/N times a frequency of the imaging-side clock (M and N are arbitrary natural numbers).
