Patent ID: 8466956

Claim:
A scanning endoscope processor, the scanning endoscope processor controlling a scanning endoscope having a first transmitter, an actuator, and a second transmitter, the scanning endoscope processor comprising: a photoelectric converter that receives light transmitted from the second transmitter and generates a pixel signal according to the amount of light received, the second transmitter transmitting reflected light and/or fluorescence from a point within an observation area illuminated by the light emitted from a first emission end, the first transmitter transmitting light from a first incident end to the first emission end, the first transmitter emitting the light as a beam from the first emission end, the actuator moving the first emission end along a spiral course, and a controller that adjusts a first angular velocity and a generation cycle so that the multiplication product of the first angular velocity, the generation cycle, and a first distance is within a predetermined range, the first emission end being vibrated along first and second diameter directions which are perpendicular to each other and perpendicular to an axial direction of the first emission end such that the first emission end is moved at the first angular velocity along the spiral course, the generation cycle being a cycle for generating the pixel signal, the first distance being a distance between the position of the first emission end on the spiral course and the center of the spiral course.
