Abstract

PURPOSE: To ensure elimination of the noise on the display pictures by giving correction to the code error word while looking at the displayed pictures by the viewer.
CONSTITUTION: The viwer, when detecting the noise on the displayed picture, operates keyboard KB to display the luminous point on the picture via index circuit IND. Then the luminous point is put in agreement with the noise position to specify the word having occurrence of the code error, and each bit within the word is altered in sequence based on the words set up by the operation of KB to turn the luminous point incomspicuous on the display screen. Under these conditions, a control is given so that the code error word of still picture memory MEMR may be rewritten with the set word. Through these serial operations, the code error can be corrected at one area. The error code frequency is normally about 10-6, and thus the noise is detected at 2 to 3 areas with every display picture. Thus, the noise can be eleiminated through these operations.
