Abstract
A camera is provided having a line-of-sight detecting device for detecting a line of sight of an observer, photometric means for detecting luminances of subareas into which a luminance detection area is partitioned, a selecting means for selecting a specific subarea from the plurality of subareas on the basis of information on the line of sight detected by the line-of-sight detecting means, and a calculating means for weighting the luminances of the plurality of subareas on the basis of the specific subarea selected by the selecting means.
