When scores of classifiers for discriminating an image to be discriminated are sequentially obtained in a predetermined order, positions of saturated pixels in the image to be discriminated are detected. For each classifier which outputs the score based on pixel values at the detected position, the score is obtained by obtaining a value determined based on a difference between a discontinuing threshold set in advance correspondingly to the identified classifier and a discontinuing threshold set in advance correspondingly to a classifier immediately before the identified classifier. For each of the other classifiers, the score is obtained by obtaining an output obtained by applying the classifier to the image to be discriminated. A sum of the scores obtained so far is compared with the discontinuing threshold. If the sum exceeds the discontinuing threshold, the score of the next classifier is obtained. |
