Electronic endoscope system provided with a means of imaging frozen pictures having few picture image smears

An electronic endoscope system comprising:

• an electronic endoscope provided with an elongate insertable part, an objective optical system provided on the tip side of said insertable part and forming an image of an object, an imaging device photoelectrically converting the image based on said objective optical system and an illuminating light emitting means emitting an illuminating light from the tip side of said insertable part;
• a driving signal outputting means outputting a driving signal outputting a picture image signal from said imaging device;
• a video signal processing means producing a video signal from said picture image signal;
• a displaying means displaying said video signal on a monitor picture surface;
• a picture image recording means which can write-in/read-out said picture image signal or said video signal;
• a movement detecting means whereby picture image signals imaged by said imaging device at different times are input and the movement amounts of the respective picture image signals are detected;
• a frozen picture memory judging means judging whether said movement amount detected by said movement detecting means is adapted to the frozen picture memorizing condition or not;
• a frozen picture memorizing signal outputting means outputting a control signal making said picture image memorizing means hold the picture image signal of the frozen picture by the judging signal judged by said judging means to be adapted to said memorizing condition;
• and
• a frozen picture directing means directing the memorization of the frozen picture adapted to said memorizing condition.
