Image processing device

摘要

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.

1. An image processing device comprising:
an image data input unit which inputs image data; an image data storage unit which stores the image data inputted through the image data input unit; an image data processing unit which outputs the image data stored in the image data storage unit; and an image data erasing unit which erases the image data stored in the image data storage unit; wherein the image data erasing unit includes an erase control unit which sets an erase processing frequency to be executed to the image data stored in the image data storage unit, and which executes a repetition of the erase processing frequency, and a display unit which displays an erase frequency information set by the erase control unit, the erase processing frequency set by the image data erasing unit includes a settable range, and the display unit displays a settable range information of the erase processing frequency.
