Abstract
Abstract A surface analysis instrument such as an electron probe microanalyzer. The instrument makes surface analyses of different regions on a sample and displays images of the regions according to the obtained information at different positions on the viewing screen of a display unit. The instrument creates a mixed histogram of the regions from the information about the regions. A level assortment is carried out according to the mixed histogram. Information about the level assortment is stored in a memory. Colors are assigned to images of the different regions according to the information about the level assortment. The images are displayed at different positions on the viewing screen.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
140 words
A surface analysis instrument comprising: a means for making surface analyses of different regions on a sample to obtain information about said regions in the format of a two dimension distribution of intensity data for each region; a means for creating a mixed histogram of said intensity data for said regions from said information obtained by said surface analyses; a means for determining the dynamic range of the mixed histogram and based thereon performing an assortment by intensity level from said mixed histogram; a storage means in which information about said intensity level assortment is stored; an assorting means for assorting images of said regions according to said intensity levels based on said information about said intensity level assortment; and a display means having a viewing screen on which said images of said different regions are displayed at different positions.
Claim 2
Dependent Claim
140 words
A surface analysis instrument comprising: a means for making surface analyses of different regions on a sample to obtain information about said regions in the format of a two dimension distribution of intensity data for each region; a means for creating a mixed histogram of said intensity data for said regions from said information obtained by said surface analyses; a means for determining the dynamic range of the mixed histogram and based thereon performing an assortment by intensity level from said mixed histogram; a storage means in which information about said intensity level assortment is stored; an assorting means for assorting images of said regions according to said intensity levels based on said information about said intensity level assortment; and a display means having a viewing screen on which said images of said different regions are displayed at different positions.
