Abstract
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.
