Abstract: An information processing system by which it is possible to easily define a lens arrangement and thus make it is possible to easily perform an optical evaluation, wherein a plurality of object positions may be defined for the same focal length of an optical lens system. A lens is designated as the lens used for focusing, and the values to be changed, such as the distances between lenses, are calculated and defined corresponding to the object positions. The arrangement of an optical system may be defined in a plurality of hierarchy levels, and information on decentering may be defined for each decentered configuration of each group including the lens faces.

Abstract: To allow smooth access to such elements as operating knobs for power window switches and a door lock switch provided in a unit panel in the night time lighting condition, the entire surface of an escutcheon panel mounted on the unit panel is defined as a switch operating part for an illuminating lamp which illuminates the elements to be accessed. The illuminating lamp may be lighted up for a prescribed time period to illuminate the escutcheon panel when the switch operating part is touched so that unnecessary consumption of electric power may be avoided. The escutcheon panel may be made of at lease semi-transparent plastic so that light from an illuminating lamp placed behind the escutcheon panel may be transmitted through the escutcheon panel. Alternatively, the element to be accessed such as a switch knob mounted on the escutcheon panel may be made of at lease semi-transparent plastic so that illuminating light may be transmitted therethrough.
