An image processing device comprises an image data input means, an image data storage meansfor storing the image data being input, an image data processing meanshaving 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. The device further comprises erase count control meansfor 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.

Image processing device

The subject invention offers data deletion operation with respect to the area storing image data for security purpose, and also offers a function for suspending the deletion operation by a specific condition so as to accept a request of processing new image data. The image processing device includes image data inputting means for inputting image data; image data storing means for storing the image data inputted by the image data inputting means; image data processing (outputting) means for processing (outputting) the image data stored in the image data storing means; image data invalidating (deleting) means for performing invalidation (deletion) of the image data stored in the image data storing means; directing means for directing cutoff of the invalidation performed by the image data invalidating means; and permitting means for permitting the cutoff of the invalidation directed by the directing means.

A digital multifunctional devicecomprises an image reading unita hard diskan image forming unitand a device control unitWhen there is input of a new image data through the image reading unitwhile the device control unitis invalidating a preceding image data stored in the hard diskthe invalidation by the device control unitof the preceding image data in the hard diskis interrupted, and the new image data being input is utilized to invalidate the preceding image data.

A digital multifunctional devicecomprises a control panelwith a LCD panelfor manipulating various settings, an auxiliary memoryfor temporarily storing the image data to be processed, an image data destruction means for destructing the image data stored in the auxiliary memory, and an operation restriction means for restricting the image data processing operation. When the digital multifunctional deviceis to be replaced or discarded, the image data destruction means destructs the image data stored in the auxiliary memory. When the stored image data is destructed by the image data destruction means, the operation restriction means restricts the subsequent image data processing operation and notifies the completion of destruction to a specified administrator.
