ABSTRACT:
A light metering system for obtaining a light value by scanning the brightness distribution of the object space within a predetermined field of view. Of the thus-produced brightness signals, those which correspond to a particular target area in the view-field are given respective predetermined weights. The light value is derived on the basis of these weighted signals and the remaining signals.
