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. ## Claims ### Claim at position 1 -17. (canceled) ### Claim 18 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 storing 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. ### Claim 19 (depends on 18) The image processing device according to claim 18, wherein the erase frequency information displayed by the display unit is the erase frequency information that is currently set, and the settable range information of the erase processing frequency. ### Claim 20 (depends on 18) The image processing device according to claim 18, wherein the erase control unit includes an input unit such as a tablet and a group of keys, and controls the change of each processing frequency with an instruction from the input unit. ### Claim 21 (depends on 18) The image processing device according to claim 18, wherein an erase processing of the image data by the erase control unit is overwriting the image data stored in the image data storage unit that became unnecessary. ### Claim 22 (depends on 18) The image processing device according to claim 18, wherein an erase processing of the image data by the erase control unit is overwriting a white data to the image data stored in the image data storage unit that became unnecessary. ### Claim 23 (depends on 18) The image processing device according to claim 18, wherein the erase processing frequency which is set by the erase control unit is a frequency of overwriting an unspecified pattern image formed by random number generation to the image data stored in the image data storage unit that became unnecessary. ### Claim 24 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 storing 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, wherein the erase control unit further comprises a changing unit which changes an image erase processing frequency for executing an initialization of the image data storing unit during power activation, and the display unit displays a range information of the image erase processing frequency that is capable of being set by the changing unit. ### Claim 25 (depends on 24) The image processing device according to claim 24, wherein the erase frequency information displayed by the display unit is the erase frequency information for executing the initialization that is currently set, and the settable range information of the image erase processing frequency. ### Claim 26 (depends on 24) The image processing device according to claim 24, wherein the erase control unit includes an input unit such as a tablet and a group of keys, and controls the change of each processing frequency with an instruction from the input unit. ### Claim 27 (depends on 24) The image processing device according to claim 24, wherein an erase processing of the image data by the erase control unit is overwriting the image data stored in the image data storage unit that became unnecessary. ### Claim 28 (depends on 24) The image processing device according to claim 24, wherein an erase processing of the image data by the erase control unit is overwriting a white data to the image data stored in the image data storage unit that became unnecessary. ### Claim 29 (depends on 24) The image processing device according to claim 24, wherein the erase processing frequency which is set by the erase control unit is a frequency of overwriting an unspecified pattern image formed by random number generation to the image data stored in the image data storage unit that became unnecessary.
