The present invention discloses an endoscope and a control method thereof. The endoscope comprises a tube, an emitting module, an image capturing module and a control module. The emitting module is disposed on one side or one end of the tube, and emits lights to an object with a first emitting mode. The image capturing module is disposed on the side or the end of the tube, and captures the reflect light from the object to generate a first image with a first capturing mode. The control module is disposed in the tube and electronically connects to the emitting module and the image capturing module, and controls the emitting module to emit lights to the object with a second emitting mode, and controls the image capturing module to capture the reflect light from the object to generate a second image with a second capturing mode.本發明係揭露一種內視鏡裝置及其控制方法,其中該內視鏡裝置包含一管體、一發光模組、一影像擷取模組以及一控制模組。發光模組係設於管體之一端或一側,並以一第一發光模式發射光線照亮一待攝物;影像擷取模組係設於管體之該端或該側,並以一第一擷取模式擷取待攝物之反射光以形成一第一影像;控制模組係設於管體中並電性連接發光模組及影像擷取模組,且於接收一切換訊號後,控制發光模組以一第二發光模式發射光線照亮待攝物,並控制影像擷取模組以一第二擷取模式擷取待攝物之反射光以形成一第二影像。
