An intraocular device includes a handheld component and an interior module. The handheld component includes an input unit, a display unit, and a processing unit. The intra vision module includes an image capturing unit for capturing images, and a gravity sensing unit for sensing gravity. Receiving an activation signal from the input unit, the processing unit controls the image capturing unit to capture an image, and controls the gravity sensing unit to sense gravity, and the processing unit receives the image from the image capturing unit. And the image, and a gravity sensing data from the gravity sensing unit, according to the image is rotated by a correction angle, and the display unit is controlled to display the image after the correction angle is rotated, the gravity sensing data is related to the image The magnitude of the deflection between the gravity sensing unit and the direction of gravity.一種內視裝置包含一手持部件及一內視模組。該手持部件包括一輸入單元、一顯示單元及一處理單元。該內視模組包括一用於擷取影像的影像拍攝單元,以及一用於感測重力的重力感測單元。該處理單元於接收到來自該輸入單元的一啟動信號時,控制該影像拍攝單元擷取影像,以及控制該重力感測單元感測重力,該處理單元並於接收到來自該影像拍攝單元的一影像,以及一來自該重力感測單元的重力感測資料時,據其將該影像旋轉一校正角度,並控制該顯示單元顯示旋轉該校正角度後的該影像,該重力感測資料相關於該重力感測單元與重力方向之間的偏轉幅度。
