Abstract
Abstract A mode designation section selectively designates a normal image scanning mode and an adjustment mode. An operation section can designate a first operation item associated with a normal image scanning operation by an image scanner section and a signal processing section when the normal image scanning mode is designated, or can designate a second operation item associated with at least one of the image scanner section and the signal processing section when the adjustment mode is designated. A display can display the first operation item when the normal image scanning mode is designated and can display the second operation item when the adjustment mode is designated. A controller supplies control signals for the normal image scanning operation or the adjustment operation to the image scanner section and the signal processing section when the normal image scanning mode or the adjustment mode is designated and the first or second operation item is designated, and supplies display signals for displaying first or second content in association with the designated first or second operation item to the display.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
137 words
An image information processing apparatus comprising: image information processing means including a plurality of elements to process image information under predetermined conditions; element testing means for outputting a number of characteristic value data corresponding to a number of said elements in order to test the plurality of elements; mode designating means for selectively designating one of a first mode for processing the image information using the image information processing means, or a second mode for testing the plurality of elements using the element testing means; and display means for displaying said predetermined conditions for processing said image by said image information processing means when said mode is designated by said mode designating means, and displaying characteristic value data corresponding to said plurality of elements output by said element testing means when said second mode is designated thereby.
Claim 2
Dependent Claim
137 words
An image information processing apparatus comprising: image information processing means including a plurality of elements to process image information under predetermined conditions; element testing means for outputting a number of characteristic value data corresponding to a number of said elements in order to test the plurality of elements; mode designating means for selectively designating one of a first mode for processing the image information using the image information processing means, or a second mode for testing the plurality of elements using the element testing means; and display means for displaying said predetermined conditions for processing said image by said image information processing means when said mode is designated by said mode designating means, and displaying characteristic value data corresponding to said plurality of elements output by said element testing means when said second mode is designated thereby.
Claim 3
Dependent Claim
35 words
