Patent ID: 7053926

Claim:
An electronic endoscope apparatus comprising: an image signal processing circuit which forms a still image signal of an object from an output signal of an image pickup device in response to a freeze switch; an image memory which stores the still image signal outputted from this image signal processing circuit; an electronic variable power circuit which reads the still image signal in the image memory on the basis of operation of an electronic variable power switch and forms a still image signal which is electronically enlarged; a control circuit which performs control of displaying the still image to a display unit by the freeze switch, wherein control of recording the still image in a recording device by the record trigger signal which occurs by the operation of a recording operation switch, wherein control of operating the electronic variable power circuit is based on the electronic variable power switch, wherein control of enlarging the still image which is stored to the image memory by the electronic variable power circuit and displaying this enlargement still image to the display unit when the electronic variable power switch is operated during the display of the still image; wherein control is such that a record trigger signal, used for recording the enlargement still image in the recording device is made to be generated when the recording operation switch is operated during the display of the enlargement still image, generation of this record trigger signal is prohibited after this generation to then prevent repeated duplicated recording of the enlargement still images of the same magnification, and wherein control is such that generation of the record trigger signal is made to be ready when the electronic variable power switch is operated after the generation of the record trigger signal is prohibited and the new enlargement still image is recorded in the recording device when a record trigger signal is generated on the basis of operation of the recording operation switch.
