SIMULTANEOUS DISPLAY DEVICE FOR GRAPHIC BEFORE AND AFTER ANALYSIS

摘要

PURPOSE:To enhance analysis efficiency by displaying the images before the analysis and after the analysis in superposition and further displaying only the image after the analysis on the superposed part. CONSTITUTION:A coordinate conversion section 42 of an arithmetic unit 4 executes coordinate conversion processing in such a manner that the coordinate data of the images before and after the analysis coincide. An overlap processing section 43 detects the overlap part of the two images and displays only the image after the analysis there. The image displays before and after the analysis are selectively displayed and the plural image parts after the analysis are successively selectively displayed only in the superposed part. Further, the size and visual field direction of the images before and after the analysis are assigned by assigning the display conditions of the images before and after the analysis and the color tones of the result of the analyses are calculated by assigning the basic colors to be analyzed.
