The present invention performs image processing to mammography image data with a filter that relatively amplifies an intermediate band component between high frequency and low frequency and/or a filter that increases and decreases components with a predetermined orientation in order to generate processed image data in which architectural distortion due to breast cancer is emphasized. In addition, this printing medium or computer readable recording medium has a processed image for supporting breast cancer diagnosis printed thereon or recorded therein, and the processed image is characterized in that the intermediate band component between high frequency and low frequency in the mammography original image is relatively amplified and/or the components with a predetermined orientation in the mammography original image are increased or decreased.本發明係對乳房攝影影像資料使用令高頻與低頻間的中間頻帶成分相對放大的濾波器及/或令具預定方位性的成分增減的濾波器進行影像處理,藉此產生將因乳癌造成的結構異常予以強調的處理影像資料。此外,本發明的印刷媒體或電腦可讀取的記錄媒體係印刷或記錄有用於輔助乳癌診斷的處理影像;在處理影像中,乳房攝影原影像的高頻與低頻間的中間頻帶成分受到相對放大及/或乳房攝影原影像的具預定方位性的成分受到增減。100‧‧‧影像處理裝置102‧‧‧控制部102a‧‧‧濾波器處理部102b‧‧‧分解部102c‧‧‧重建部102d‧‧‧加權部102e‧‧‧影像尺寸‧輝度調整部102f‧‧‧色空間轉換部102g‧‧‧處理影像輸出部104‧‧‧通訊控制介面部106‧‧‧記憶部106a‧‧‧濾波器檔案106b‧‧‧影像資料檔案108‧‧‧輸出入控制介面部112‧‧‧輸入裝置114‧‧‧輸出裝置200‧‧‧外部系統300‧‧‧網路
