A scanning laser microscope includes a laser generation unit which
generates a laser beam, a light modulation unit which modulates the laser
beam, a scanning unit which scans a sample, a light receiving unit which
receives a light from the sample, a control unit which controls the light
modulation unit for each pixel of a scanning image acquired by the light
receiving of the light receiving unit, and a storage unit which stores a
plurality of controlled patterns. The number of pixels of the patterns
correspond to the number of pixels of the scanned image. A modulation
information of the laser beam is set for each pixel. The control unit
reads the control patterns stored in the storage unit, controls the light
modulation unit based on the modulation information of each pixel, and
performs such control that the control patterns are changed at an
arbitrary timing.
