Abstract

An image processing device comprises an image data input means 2, an image data storage means 12 for storing the image data being input, an image data processing means 6 having multiple processing modes for outputting the stored image data, and a image data erasing means for erasing the image data stored in the storage means 12. The device further comprises erase count control means 8, 14 for controlling the number of times for erasing image data capable of having the number of times of erase set arbitrarily according to the security level required for each mode, and capable of having the set number of times of erase changed in mid-flow. Confidentiality is protected by performing erase operations repeatedly to the region storing the unnecessary image data according to the security level.

Description

TECHNICAL FIELD [0001] The present invention relates to an image processing device such as a digital multifunctional device including a scanner and a printer, and preferably relates to an image processing device connected to a communication path such as a network and having, in addition to the copier function mentioned above, an image communicating function and a printer function, and more specifically, relates to an image processing device that temporarily stores the image data inputted to the multifunctional device in a memory equipped thereto so as to process the input image data, and erases the stored image data from the memory when the processing is completed. DESCRIPTION OF THE BACKGROUND ART [0002] Conventionally, digital multifunctional devices are available in the market for electronically scanning a document image by a scanner and outputting the image data transmitted from the scanner through a printer. Recently, improved digital multifunctional devices have appeared, equi...
