Abstract
PURPOSE: To quicken both sequential row-by-row access and column-by-column access in a picture memory unit, by changing the data format of picture information in the memory unit.
CONSTITUTION: A sequential shift on a row unit is controlled by counter 16 and if a block inside of memory part 1 overflows, a column unit is shifted by counter 15. For the purpose, the output of pulse generator 11 is inputted to both counters 15 and 16 at the same time, whose counting phases are changed synchronizing with the shift of the shift register inside of memory part 1, so that addresses of the column and row will be changed one by one.
