Abstract: An endoscope apparatus includes: an imaging portion imaging a subject to generate image data; a designation portion designating a position in an image based on the image data; an image processing portion processing the image data such that an enlarged image obtained by enlarging an image in a second region including the designated position overlaps a first region including the designated position designated by the designation portion; a display portion displaying the enlarged image and the image of the subject based on the image data processed by the image processing portion and displays a cursor at the designated position on the enlarged image; and a measurement processing portion performing measurement on the basis of a measurement position indicated by the cursor by using the image data generated by the imaging portion. The enlarged image displayed on the display portion moves according to movement of the cursor.

Abstract: A nondestructive testing apparatus includes a display section and a storage section which stores predetermined executable functions. Each of the predetermined functions is initially set to one of a permitted state and a disabled state, and one of a display state and a non-display state on the display section. In an initial state, at least one of the predetermined functions is set to the disabled state and the non-display state. The nondestructive testing apparatus can receive permission information which unlocks at least one of the predetermined functions initially set to the disabled state so as to be set to the permitted state, and unlocks at least one of the predetermined functions initially set in the non-display state so as to be in the display state. The apparatus displays an operation icon only with respect to all of the predetermined functions set to the display state.
