SU1667146A1 - Device for displaying graphic information - Google Patents

Abstract

The invention relates to automatic and computer technology and can be used to display graphic information from a computer. The purpose of the invention is to expand the field of application of the device due to the possibility of horizontal scaling of the graphic image horizontally - the introduction of the first register 3, second register 9, counter 10, third register 11, second switch 12, converter 13 codes, group 15 of switches 16, group 17 of triggers 18 and corresponding functional relationships. The invention allows for displaying graphic information to transform information corresponding to a panoramic zoom. 4 il.
