Claims (8)

記憶手段に記憶されている消去対象の画像データの一部のみを消去する第１の消去手段と、 前記記憶手段に記憶されている消去対象の画像データの全領域を消去する第２の消去手段と、 画像データの消去に際し、装置の動作状態に応じて、前記第１，第２の消去手段のうちのいずれかを選択する選択手段と、 前記選択手段により選択した消去手段による消去処理を実行させる制御手段と、 を備えたことを特徴とする画像処理装置。 A first erasing unit for erasing only a part of the image data to be erased stored in the storage unit; and a second erasing unit for erasing the entire area of the image data to be erased stored in the storage unit. When erasing image data, a selection unit that selects one of the first and second erasing units according to the operating state of the apparatus, and an erasing process by the erasing unit selected by the selection unit are executed. An image processing apparatus comprising: control means for causing 前記記憶手段に記憶される画像データがＪＢＩＧ形式で圧縮された画像データであり、 前記第１の消去手段は、前記圧縮された画像データの復元情報を有する各プレーンの先頭データのみを消去することにより画像データを復元不可能とし、 前記第２の消去手段は、前記圧縮された画像データの全領域を消去することにより画像データを復元不可能とする請求項１に記載の画像処理装置。   The image data stored in the storage means is image data compressed in JBIG format, and the first erasure means erases only the head data of each plane having restoration information of the compressed image data. 2. The image processing apparatus according to claim 1, wherein the image data cannot be restored by the second erasure unit, and the second erasure unit cannot erase the image data by erasing the entire area of the compressed image data. 装置の動作状態が、データ消去に係るジョブ以外の未処理ジョブが有るか否かであり、 前記選択手段は、データ消去に係るジョブ以外の未処理ジョブが有る場合には第１の消去手段を選択し、未処理ジョブが無い場合には第２の消去手段を選択する請求項１または２に記載の画像処理装置。   The operation state of the apparatus is whether or not there is an unprocessed job other than the job related to data erasure, and the selection unit selects the first erasure unit when there is an unprocessed job other than the job related to data erasure The image processing apparatus according to claim 1, wherein the second erasing unit is selected when there is no unprocessed job selected. 装置の動作状態が、データ消去に係るジョブ以外の未処理ジョブが有るか否か及びこの未処理ジョブの処理優先レベルであり、 前記選択手段は、処理優先レベルの高い未処理ジョブが有る場合には第１の消去手段を選択し、無い場合には第２の消去手段を選択する請求項１または２に記載の画像処理装置。   The operation state of the apparatus is whether or not there is an unprocessed job other than the job related to data erasure and the processing priority level of this unprocessed job. 3. The image processing apparatus according to claim 1, wherein the first erasing unit is selected, and if there is no second erasing unit, the second erasing unit is selected. 記憶手段に記憶されている消去対象の画像データの一部のみを消去する第１の消去方法により消去するか、全領域を消去する第2の消去方法により消去するかを、ジョブの状況に応じて選択するステップと、 選択した消去処理方法で画像データを消去するステップと、 を備えたことを特徴とする画像処理方法。 Whether to erase by the first erasing method for erasing only a part of the image data to be erased stored in the storage means or by the second erasing method for erasing the entire area according to the job status An image processing method comprising: a step of selecting the image data; and a step of erasing the image data with the selected erasure processing method. 前記記憶手段に記憶される画像データがＪＢＩＧ形式で圧縮された画像データであり、 前記第１の消去方法は、前記圧縮された画像データの復元情報を有する各プレーンの先頭データのみを消去することにより画像データを復元不可能とする方法であり、 前記第２の消去方法は、前記圧縮された画像データの全領域を消去することにより画像データを復元不可能とする方法である請求項５に記載の画像処理方法。   The image data stored in the storage means is image data compressed in JBIG format, and the first erasing method erases only the head data of each plane having restoration information of the compressed image data 6. The method according to claim 5, wherein the second erasing method is a method of making the image data unrecoverable by erasing the entire area of the compressed image data. The image processing method as described. データ消去に係るジョブ以外の未処理ジョブが有る場合には第１の消去方法を選択し、未処理ジョブが無い場合には第２の消去方法を選択する請求項５または６に記載の画像処理方法。   The image processing according to claim 5 or 6, wherein when there is an unprocessed job other than a job related to data erasure, the first erasing method is selected, and when there is no unprocessed job, the second erasing method is selected. Method. データ消去に係るジョブ以外に処理優先レベルの高い未処理ジョブが有る場合には、第１の消去方法を選択し、無い場合には、第２の消去方法を選択する請求項５または６に記載の画像処理方法。   7. The first erasing method is selected when there is an unprocessed job with a high processing priority level other than the data erasing job, and the second erasing method is selected when there is no unprocessed job. Image processing method.
