Abstract

PURPOSE: To obtain a detailed picture easily by adding a detailed-picture shift register without increasing the capacity of a picture memory.
CONSTITUTION: With address counter 4 in mode W, detailed-picture shift register 8 is in a data write mode and coded picture data of the detailed-picture memory part of picture memory 2 are transferred as coded and detailed picture data to each line address part. With address counter 4 in mode R, on the other hand, line address multiplexer 7 supplies the coded picture data of picture memory 2 to the line address of detailed-picture shift register 8. When bits of the coded picture data outputted from picture memory 2 are all zero, line addresses are selected corresponding to the data and coded and detailed picture data in detailed-picture shift register 8 are outputted.
