Abstract
The present invention provides an electronic device and the like that can prevent the leakage of information related to a display image through an observation signal of an electromagnetic signal emitted from an electronic device or the like. The electronic device (10) includes a display control unit (11a) that causes a display unit (15) to display a display image that has been formed based on information, and a modification control unit (11b) that performs modification processing on a modification-target image element specified by a character code or vector information included in the information. The display control unit (11a) causes the display unit (15) to display the display image after the modification processing has been performed on the modification-target image element by the modification control unit (11b).

23. An electronic device comprising:
-
a display unit; a display control unit that forms a display image based on information, and causes the display unit to display the display image; and a modification control unit that performs modification processing on a modification-target image element specified by a character code or vector information included in the information, wherein the display control unit causes the display unit to display the display image after the modification processing has been performed on the modification-target image element by the modification control unit, and the modification processing is processing that performs modification on an outline portion of the modification-target image element, or processing that replaces the modification-target image element with a preprovided modified image element in which the outline portion has been modified. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 38, 39)

34. An image modification method for modifying a display image displayed on a display unit of an electronic device, the method comprising the steps of:
-
performing modification processing on a modification-target image element specified by a character code or vector information included in a display image that is formed based on information; and causing the display unit to display the display image after the modification processing has been performed on the modification-target image element, wherein the modification processing is processing that performs modification on an outline portion of the modification-target image element, or processing that replaces the modification-target image element with a preprovided modified image element in which the outline portion has been modified.

35. An information processing device that performs processing on a file having an information item including image formation information used for forming a display image, the device comprising:
-
an information moving unit that moves at least a portion of the image formation information included in the information item of the file that is supplied, from the information item to an item included in the file other than the information item or to a predetermined storage location outside the file; and an information adding unit that adds, to the information item of the file, alternate image formation information that can be processed using software capable of opening the file, in place of the at least a portion of the image formation information that has been moved. - View Dependent Claims (36, 37)

40. An information processing method for performing processing on a file having an information item including image formation information used for forming a display image, the method comprising the steps of
moving at least a portion of the image formation information included in the information item of the file that is supplied, from the information item to an item in the file other than the information item or to a predetermined storage location outside the file; - and
adding to the information item of the file, pre-defined alternate image formation information that can be processed using software capable of opening the file, in place of the at least a portion of the image formation information that has been moved.

41. An image modification method for performing alteration on an information image in an electronic device including an image display device such that an electromagnetic signal correlated with the information image included in a display image displayed on a display screen of the image display device will not be emitted,
wherein a modification portion is added to an outline portion of the information image as the alteration.
