SCREEN NUMBER GIVING METHOD AND CIRCUITS

摘要

The circuit includes a multi-picture memory means and a line memory means (10) for reading picture data in accordance with picture addresses to continuously output a plurality of pictures. A picture number input switching means (64) selects a picture input mode, and a comparing means receives a picture memory address designation signals to compare them with a reference address, and outputs the relevant address upon finding the correspondence between the two addresses. A numeral data generating means (62) generates numeral data in accordance with the output address of the comparing means, and a gate means (63) logic-combines the picture data of the multi-picture memory means and the numeral data of the numeral data generating means (62) to output them to the line memory means (10).
