Abstract
PURPOSE: To get output which can be indicated by so many functions as a distance to a subject by a method wherein two light sources arranged opposing to the subject keeping an appropriate interval are made to emit light to radiate the subject for comparing luminance.
CONSTITUTION: The first light source 6 and the second light source are arranged to a subject 12 at Do intervals through the lenses 14, 15 provided in front of the second light source 7. And the irradiation scope of the subject 12 by the light source 6 and the light source 7 are made to fall on about the same surface, further a light reception scope of a light reception sensor 13 is made same as or little brighter than the subject face irradiated by the two light sources 6, 7. The reception light quantity of the reception light sensor 13 is converted into an electrical quantity at the reception light part 16 to compare the subject luminance through the brightness of the light source 6 and that through the brightness of the light source 7 by the electrical quantity in an arithmetic circuit 17. And the output of the arithmetic circuit 17 can be indicated through the function only of the distance Dx to the subject 12 as shown in the formula at right by the simple adjustment of circuit constant.
