1. An electronic endoscope apparatus, comprising:

  • various electronic scopes each equipped with a solid state image pickup device with a different image size;

    a processor unit which is removably connected with the electronic scopes and records, on a recording medium, image data of an object under observation formed based on output from the solid state image pickup device;

    a clock signal generator circuit which is mounted on the processor unit and generates clock signals with a plurality of frequencies according to image sizes obtained by the electronic scopes;

    an image storage memory which is mounted on the processor unit, stores image data in response to an image capture command, and transfers the image data to the recording medium; and

    a processor-side control circuit which judges in response to a redisplay command whether the image size for the connected electronic scope matches the image size of the data in the image storage memory, changes the clock signal generated by the clock signal generator circuit to the one suitable for the image size in the image storage memory if no match is found, and redisplays the image data read out of the image storage memory using the clock signal with this frequency on the display device.
