Camera

Abstract

A camera is provided with an exposure arithmetic apparatus for patterning a field to calculate an amount of exposure. The exposure arithmetic apparatus has a light amount measuring portion for measuring amounts of light for a plurality of segmental zones of the field, a pattern generating portion for generating a plurality of patterns for spatially pattern-classifying the field, a correlation arithmetic portion for calculating correlation values each indicating a degree of correlation of each pattern with the field, based on outputs from the light amount measuring portion and the pattern generating portion, a pattern luminance calculating portion for performing an arithmetic process based on an output from the pattern generating portion, of the output from the light amount measuring portion, and an exposure arithmetic portion for calculating correct exposure, based on outputs from the correlation arithmetic portion and pattern luminance calculating portion.
