Observation apparatus

摘要

An observation apparatus including: a light source unit that generates illumination light by using a plurality of solid-state illumination devices; an image-acquisition device that acquires an image of an object illuminated with the illumination light; an image processing unit that processes acquired image signals; and a control unit that controls the light source unit and/or the image processing unit. One of the illumination devices has a peak in a G channel, another one of the illumination devices has a peak in an R channel, and, when increasing and reducing the amount of the illumination light, the control unit performs control so as to satisfy ΔSr/ΔSg>1 and ΔSr/ΔSg<1, respectively, where ΔSr and ΔSg are rates of change of system gains applied to the R and G channels, respectively.

1. An observation apparatus comprising:
a light source unit that generates illumination light by using a plurality of solid-state illumination devices; an image-acquisition device that acquires an image of an object illuminated with the illumination light generated by the light source unit; an image processing unit that processes image signals acquired by the image-acquisition device; and a control unit that controls at least one of the light source unit and the image processing unit, wherein at least one of the solid-state illumination devices of the light source unit has a peak in a G channel, at least another one of the solid-state illumination devices of the light source unit has a peak in an R channel, and, when the control unit increases an amount of the illumination light emitted from the light source unit, the control unit performs control so as to satisfy Conditional Expression (1), and, when the control unit reduces the amount of the illumination light emitted from the light source unit, the control unit performs control so as to satisfy Conditional Expression (2):
ΔSr/ΔSg>1  (1)ΔSr/ΔSg<1  (2)where ΔSr is a rate of change of a system gain applied to an R-channel image signal among the image signals, and ΔSg is a rate of change of a system gain applied to a G-channel image signal among the image signals.
