Abstract

PURPOSE: To make it possible to display a picture pattern at any place on a CRT by equipping a pattern memory, picture position processor, pattern assignment memory, and sequential reader for pattern assignment memories.
CONSTITUTION: By computing the position of a picture pattern on the CRT, picture position processor 3 outputs signals for picture position relation and horizontal occupancy length ΔX assignment via the address line and a pattern-code assignment signal of the pitcure pattern via the data line to pattern assignment memory 4. Data in memory 4 are read out line by line in sequence by pattern-assignment-memory sequential reader 5; data on ΔX are stored in horizontal occupancy length memory circuit 14, and data on pattern codes are in pattern memory 7. When the data on ΔX agrees with the value obtained by increasing a pattern sending clock from timing generating circuit 6, horizontal occupancy length comparator circuit 15 generates a coincidence pulse and a picture signal is sent out from memory 7 via shift register 8. As a result, assigning ΔX makes it possible to display a picture at any position freely.
