A capsule camera with onboard data storage includes a camera capable of capturing images including an initial image frame and a next image frame. The onboard data storage is capable of storing image data associated with the images. The capsule camera also includes a volatile memory unit capable of temporarily storing the image frames, a control subsystem capable of comparing the image frames, and transmitting the next image frame to the onboard data storage if the next image frame differs from the initial image frame. A method for recording video with a capsule camera includes capturing an initial image frame using a camera, capturing a next image frame at an initial duration after capturing the initial image frame, and comparing the initial image frame and the next image frame, and optionally transmitting the next image frame to the onboard data storage.一種具有機載資料儲存器的膠囊相機包括一相機，所述相機能夠捕捉包括初始影像圖框及下一影像圖框的影像。所述機載資料儲存器能夠儲存與所述影像相關聯的影像資料。所述膠囊相機亦包括：揮發性記憶體單元，其能夠暫時性地儲存所述影像圖框；控制子系統，其能夠比較所述影像圖框，且在所述下一影像圖框不同於所述初始影像圖框的情況下將所述下一影像圖框傳輸至所述機載資料儲存器。一種用於用膠囊相機記錄視訊的方法包括：使用相機捕捉初始影像圖框；在捕捉所述初始影像圖框之後以初始持續時間捕捉下一影像圖框；及比較所述初始影像圖框與所述下一影像圖框；及視情況將所述下一影像圖框傳輸至機載資料儲存器。
