ENLARGEMENT DISPLAY CONTROL SYSTEM FOR IMAGE DATA

摘要: PURPOSE:To enable a smooth scroll processing by equipping an enlargement control part with offset latch means which latches display frequency information on start data and generating for address enabling signal counting clock integral value of magnification. CONSTITUTION:The 6 the starts decreasing from magnification as its starting value. When is are displayed excessively according to small magnification, they inputted counter 4, setting 8 sets corresponding in 1st 2nd 10 12 11 13, 7 synchronism horizontal synchronizing image data, AND gate 9 inputs 4 when outputted 6. Then various enlarging processes performed carried out.
