Abstract: A scanning endoscope apparatus includes: a light source unit; an illumination fiber inserted inside an insertion portion of an endoscope, the illumination fiber being configured to guide illuminating light from a proximal end to a distal end; an actuator configured to drive the distal end of the optical fiber so that the illuminating light outputted from the illumination fiber is scanned on a subject; a memory configured to store correlation coefficient information on a correlation coefficient between a drive signal for driving the actuator and a displacement amount of the actuator; and a controller, and the controller detects a current of the drive signal for driving the actuator and corrects the drive signal for driving the actuator based on the correlation coefficient information and a value of the detected current so that the displacement amount of the actuator becomes a predetermined value.

Abstract: An endoscope system includes: an illumination unit configured to irradiate a visual field area with illumination light that produces return light from a specific substance; a sensor unit having a two-dimensional surface on which a plurality of pixels is arranged for receiving the return light from the visual field area and photoelectrically converting the return light to generate electrical signals; a reading unit configured to read out the electrical signals per a specified frame cycle; a reset pulse generation unit configured to generate reset pulses for releasing electric charges accumulated in the plurality of pixels; a reset pulse controller configured to adjust timing of generating the reset pulses such that a plurality of frame cycles is included in a period between generation of two consecutive reset pulses; and an illumination controller configured to cause the illumination unit to emit the illumination light in each of the plurality of frame cycles.
