Claim Text:
1. A scanning laser microscope comprising: a scanner that two-dimensionally scans laser light emitted from a light source on a specimen; a detector that detects light from the specimen on which the laser light is scanned by the scanner and that outputs a light intensity signal that corresponds to a light intensity of the detected light; a computer that converts the light intensity signal output from the detector to brightness information at each pixel corresponding to a scanning position of the scanner and that generates an image of the specimen; an integrating circuit that calculates light intensity information corresponding to a total light intensity signal output from the detector within a given time; a comparator that determines whether or not the light intensity information calculated by the integrating circuit exceeds a prescribed threshold; and a controller that stops detection of light by the detector when it is determined by the comparator that the light intensity information exceeds the prescribed threshold, wherein the computer generates the image of the specimen by accumulating the brightness information converted at each pixel at a prescribed pixel clock; and wherein the integrating circuit sets, as the light intensity information, an integrated value obtained by integrating, over a period longer than the pixel clock of the computer, the light intensity signal output from the detector within the given time.
