OPTICAL-SCANNING-TYPE OBSERVATION DEVICE

摘要

The present invention makes it possible to reduce electrical-current consumption while suppressing a decline in image resolution. This optical-scanning-type observation device (10) is equipped with: a light source for selectively emitting light of a plurality of different colors; a light-emission-timing control unit (32) for controlling light-emission timing on the basis of a prescribed light-emission frequency ratio for each color of light from the light source; a fiber (11) for optically guiding the light from the light source; a drive unit (21) for oscillating and driving the tip of the fiber; optical systems (25a, 25b) for radiating the light emitted by the optical fiber; a photodetection unit (35); and a signal processing unit (37).
