19. An image acquiring method for an encapsulated endoscope comprising the steps of:
-
generating a control signal of the direction of the encapsulated endoscope; rotating the encapsulated endoscope based on the control signal; acquiring n-th image data using the encapsulated endoscope and storing the n-th image in a memory; acquiring n+1-th image data using the encapsulated endoscope; calculating the rotational phase of the encapsulated endoscope based on the control signal attained when the n+1-th image data is acquired; rotating the n+1-th image data corresponding to the rotational phase; determining a correction to the rotation by comparing the rotated n+1-th image data with the stored n-th image data; providing a corrected rotation to the rotated n+1-th image data; and storing the image data, which has been corrected as the n+1-th image in the memory.
