ABSTRACT:
An endoscopic imaging system for producing a flatly deployed expansion image of a tubular body cavity. The endoscopic imaging system essentially includes a photoelectric line sensor rotatably mounted on a distal end portion of an endoscopic insertion instrument for picking up a series of slit images around inner periphery of a tubular intracavitary wall sequentially at predetermined angular positions within an axial range commensurate with axial length of the line sensor; and an expansion image generating means arranged to produce a frame of picture signals for a flatly deployed expansion image of the tubular intracavitary wall from picture signals of slit images sequentially received from the image sensor.
