1. A wireless endoscope system, comprising:

  • an imaging unit that captures an image and generates imaging data;

    a freeze-instructing unit that generates a still image display signal relevant to an execution of a still image display;

    a data storage unit that stores the imaging data as storage data at a time at which the still image display signal is switched from a first state indicating an execution of a moving image display to a second state indicating the execution of the still image display;

    a moving image-compressing unit that performs a moving image-compressing process on the imaging data and generates moving image data;

    a still image-compressing unit that performs a still image-compressing process on the storage data and generates a plurality of pieces of still image data;

    an image quality control unit that controls image quality of the plurality of pieces of still image data such that image quality of a piece of still image data generated later among the plurality of pieces of still image data becomes higher;

    a data-selecting unit that selects the moving image data when the still image display signal is in the first state, and sequentially selects the plurality of pieces of still image data in an order in which the plurality of pieces of still image data are generated when the still image display signal is in the second state;

    a transmission unit that transmits the moving image data or the plurality of pieces of still image data selected by the data-selecting unit in a wireless manner;

    a reception unit that receives the moving image data or the plurality of pieces of still image data transmitted from the transmission unit in a wireless manner;

    an image-decompressing unit that performs a decompressing process on the moving image data or the plurality of pieces of still image data received by the reception unit and generates display data, the image-decompressing unit generating a plurality of pieces of the display data in an order in which the plurality of pieces of still image data are generated in the decompressing process on the plurality of pieces of still image data;

    an image display unit that performs a display process based on the display data;

    a target image-designating unit that designates the display data as target image data when the image quality of the piece of still image data is equal to or higher than a predetermined image quality;

    an image storage unit that stores the display data designated as the target image data; and

    a high image quality requesting unit that generates a high definition request signal relevant to a request for a piece of still image data with a predetermined highest image quality,wherein the image quality control unit sets the image quality of the piece of still image data to the highest image quality when the still image display signal is in the second state and the high definition request signal is in a third state indicating a request for still image data with the highest image quality before a final piece of still image data among the plurality of pieces of still image data is generated, andthe image quality control unit gradually changes the image quality of the plurality of pieces of still image data such that the image quality of the piece of still image data generated later becomes higher and image quality of a piece of still image data generated finally becomes the highest image quality when the still image display signal is in the second state and the high definition request signal is in a fourth state other than the third state before the final piece of still image data among the plurality of pieces of still image data is generated.
