Patent ID: 7254321

Claim:
An image capturing apparatus comprising: a preliminary-emission control unit configured to perform preliminary light emission to a subject; a photometric unit configured to measure brightness of the subject in a picture frame having a plurality of areas at a first timing when the preliminary-emission control unit is not performing preliminary light emission and at a second timing when the preliminary-emission control unit is performing preliminary light emission; a calculating unit calculating a ratio between first photometric information indicating the brightness measured by the photometric unit at the first timing and second photometric information indicating the brightness measured by the photometric unit at the second timing, the calculating unit calculating the ratio for each of the plurality of areas; an extracting unit extracting a reference ratio from among the ratios of the plurality of areas calculated by the calculating unit; an evaluation-value calculating unit comparing the reference ratio extracted by the extracting unit with the ratios of the plurality of areas calculated by the calculating unit, and calculating an evaluation value for each of the plurality of areas based on the comparison; and an actual-emission-light calculating unit evaluating the second photometric information for each area based on the evaluation value of each area calculated by the evaluation-value calculating unit, and calculating an amount of light to be emitted in an exposure operation based on the evaluation.
