ABSTRACT:
A color separating optical apparatus is provided with a compensating members in order to compensate for the differences in output energy of the separated colors which is attributable to the particular spectral characteristics of the light source and the light receiver. In various embodiments, selectable masks are used to control the light flux, or the light source itself is controlled as to the number of lamps energized for each color.
