Abstract: A capsule endoscope, an endoscope system, and an image correction method are provided. The capsule endoscope includes an image sensor and a posture sensor. The image sensor is coupled to a processor and obtains a sensed image. The posture sensor is coupled to the processor and obtains three-axis data. The processor calculates a screen rotation angle according to the three-axis data and corrects the sensed image according to the screen rotation angle. A first axis and a second axis of the corrected sensed image rotate toward an actual vertical axis and an actual horizontal axis.

Abstract: An endoscope includes a control module, a lens module, a cover, and an encapsulation. The lens module is electrically connected to the control module. The cover has a transparent area, and the cover covers the lens module in a sealing manner. The encapsulation encapsulates the cover and the control module, and exposes the transparent area, such that the encapsulation serves as a shell of the endoscope.
