摘要： An imaging device (114) is installed on a scope distal portion (110), and captures an image based on an imaging clock. An image processor portion (120) performs image processing on the image captured by the imaging device (114), and displays the corresponding image based on a display clock on a monitor. A scope cable portion (130) transmits data between the scope distal portion (110) and the image processor portion (120). A clock oscillator (111) generates a master clock. A first multiplying/dividing circuit (112) multiplies and/or divides the master clock by (natural number/natural number), and generates a transmission clock whose frequency is lower than that of the imaging clock and is (natural number) times the frequency of a vertical synchronization signal.

摘要： 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 a 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 a phase of the imaging synchronization signal (105) with a phase of the display clock (216), and controls oscillation of the display clock generating unit (215) based on a result of the comparison.
