PROBLEM TO BE SOLVED: To provide an electronic endoscopic apparatus for securing synchronization between imaging and display.SOLUTION: A CMOS sensor 106 converts optical information into an electric signal and outputs the converted electric signal as an image signal 107. An imaging clock generating unit 101 generates an imaging clock 102 acting as the source of a drive signal that drives the CMOS sensor 106. A drive signal generating unit 103 generates an imaging synchronization signal 105 and a drive signal 104 based on the imaging clock 102. A display clock generating unit 215 generates a display clock 216. A display synchronization signal generating unit 217 generates a display synchronization signal 218 based on the display clock 216. A phase comparing unit 213 compares the phase of the imaging synchronization signal 105 with the phase of the display clock 216 and controls oscillation of the display clock generating unit 215 based on the result of the comparison.COPYRIGHT: (C)2013,JPO&INPIT
