A mammary gland content rate r(x, y) is calculated for each pixel of a mammogram obtained by a radiation imaging apparatus. Thereafter, an average value rave of the mammary gland content rates within a breast region MR is calculated, using the mammary gland content rates r(x, y) of each pixel. Abnormal pixels that constitute abnormal patterns are detected, employing the mammary gland content rates r(x, y), the average value rave, and a set reference value Rref.
