Light measuring system |
摘要 |
A light measuring system is specified for obtaining an exposure value by scanning the brightness distribution of the object space within a specific visual field. Those of the brightness signals produced in this way which correspond to a particular target area in the visual field are respectively provided with predetermined evaluating weights. The exposure value is derived from these evaluated signals and the remaining signals.
