The present invention relates to an endoscopic device with one to many synchronous displays, including an endoscopic unit and at least one display device, the endoscopic unit takes a image via a lens and produces a digital image data. The digital image data can send to the display device via the wireless, and can display on the screen of the display device. The screen is a touch screen, and it can be generated a touch trajectory data by touching the screen. The touch trajectory data can send to the other display devices via the wireless, and can display on the screen of these display devices.本發明係提供一種一對多同步顯示之內視鏡裝置,其包含一內視鏡單元以及至少一以上之顯示裝置,該內視鏡單元透過一鏡頭攝取一影像並產生一影像數位資料,透過無線傳輸方式進行發送至顯示裝置,並顯示在顯示裝置之螢幕上,該螢幕可為觸控式螢幕,其可藉由觸控產生一觸控軌跡資料,並透過無線傳輸方式將該觸控軌跡資料進行發送至其他顯示裝置,並顯示在其他顯示裝置之螢幕上。20...內視鏡單元21...鏡頭22...影像感測單元23...第一無線發射單元24...第一電池25...系統處理單元30...顯示裝置31...第一無線接收單元32...螢幕33...第二電池34...第二無線發射單元
