User interface for inspection system with isoluminant regions
First Claim
1. A method of operating an inspection system, comprising:
- determining at least a first characteristic and a second characteristic for each of a plurality of regions in an item under inspection;
for each of the plurality of regions, assigning a color value based on a value of the first characteristic determined for the region and an intensity value based on a value of the second characteristic determined for the region and the color value assigned to the region; and
displaying an image of the item under inspection containing a plurality of pixels, with each pixel having the assigned color and intensity value for at least one region of the plurality of regions.

Abstract
An inspection system having a user friendly operator display. Characteristics of items under inspection are represented in the display by color and brightness. Each pixel on the display is assigned an intensity representation of a first characteristic of a region of an item, such as density. Color is assigned to each pixel based on anther characteristic of the regions, such as atomic number. The intensity assigned to each pixel in the display is based in part on the color assigned to that pixel so that each pixel representing the same value of the first characteristic will appear to a human with the same brightness, regardless of the color assigned to the pixels. Such a display is used in an x-ray inspection system to represent attenuation of x-rays by brightness and effective atomic number by color.

10. An inspection system, comprising:
-
a data acquisition system that acquires, for each of a plurality of regions in an item under inspection, a plurality of measurements indicative of radiation passing through the region and an effective atomic number of material in the region;
a processor coupled to the data acquisition system to receive, for each of the plurality of regions, the plurality of measurements;
a display having a plurality of pixels and an input, coupled to the processor, adapted to receive at least one control signal controlling the plurality of pixels;
computer-readable medium coupled to the processor, the computer-readable medium having computer-executable instructions for;
mapping, for each region, the plurality of measurements to control values for a pixel of the display, the mapping using a color-dependent relationship between the plurality of measurements and intensity, to produce a set of control values representative of an image of an item under inspection; and
generating the at least one control signal from the set of control values. - View Dependent Claims (11, 12, 13)

14. A computer-readable medium having a plurality of computer-executable instructions for:
-
for each of a plurality of regions of an item under inspection;
receiving at least two measured values indicative of attenuation of penetrating radiation through the region;
assigning a color value based on the at least two measured values for the region and an intensity value based on at least one of the at least two measured values for the region and the color value assigned to the region; and
displaying an image of the item under inspection containing a plurality of pixels, with each pixel having an appearance based on the assigned color and intensity value for at least one region of the plurality of regions. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
