ABSTRACT:
The present invention relates to an exposure computation circuit by means of which a computation is carried out with the values inversely proportional to all the exposure factors excepting the diaphragm value of the APEX system so as to obtain computation results in proportional relation with the actual shutter time value or the actual diaphragm value in order to control the exposure basing upon the computation results.
