Document Type and Number:
Japanese Patent JPH07113966
Kind Code:
B2
Abstract:
To obtain an enhanced two-dimensional image of a raised, light-reflective reflective feature (12), and its lower height surrounding background such that the contrast between them is enhanced, a line of light having a gradient profile is directed at an acute angle at the feature and its background to illuminate a strip of area thereacross. The reflectance intensity of the illuminated strip will vary in accordance with the height thereof because of the gradient intensity profile of the line of light. When the line of light is spanned across the feature and its background, the resultant image of the feature and its background, captured by spanning a linescan camera (24) thereacross, will exhibit an enhanced contrast between the feature and its background because of the greater height of the feature.
