Endoscope system, image processing device, image processing method, and program

An image processing device for image stabilization of an image signal input from an endoscope device including an objective lens provided at a distal end, the objective lens being disposed such that an optical axis of the objective lens and longitudinal axis of the objective lens intersect a predetermined angle, an endoscope head provided at a proximal end, and a gyro sensor provided on the endoscope head and configured to detect an angular velocity of movement of the endoscope head, image processing device comprising:

• circuitry configured to
• calculate a shift amount of the distal end of the endoscope device using the detected angular velocity of movement of the endoscope head provided at the proximal end, and
• implement the image stabilization of the image signal input from the endoscope device based on the calculated shift amount of the distal end of the endoscope device.
