Claim One:
1. An indoor-outdoor detection method, the method comprising: constructing a first indoor-outdoor detector; constructing a second indoor-outdoor detector; determining a normalized brightness of a subject image; generating a comparison result based on the determined normalized brightness and a threshold brightness value; selecting one of the first detector or the second detector, based on the comparison result; applying the selected detector to the subject image to generate a detection result; and performing image signal processing on the subject image based on the detection result, wherein selecting one of the first detector and the second detector includes selecting the first detector if the normalized brightness of the subject image exceeds the threshold brightness value and selecting the second detector if the normalized brightness of the subject image is less than or equal to the threshold brightness value, the first indoor-outdoor detector being a high brightness indoor-outdoor detector, the second indoor-outdoor detector being a low brightness indoor-outdoor detector.
