THREE-DIMENSIONAL DISPLAY SYSTEM

摘要

PURPOSE:To make an accurate analysis and a judgement even when data on numbers of density levels coexit complicatedly by displaying only section pattern matching with specific condition. CONSTITUTION:A setting part 11 enters condition for selecting data to be sent from a three-dimensional memory 10 to a frame buffer 18 into the 1st register 12 and the 2nd register 13. Density r1 is inputted to the 1st register 12 and density r2 is inputted to the 2nd register 13. The 1st comparator 14 and the 2nd comparator 15 each generate an output at three terminals selectively according to the relation between a reference value applied to an input terminal A and data applied to an input terminal B. A condition selector 19 selects the condition to be held by a picture element to be set from the three-dimensional memory 10 to the frame buffer 18.
