PURPOSE:To improve practical resolution in respect to a scan line to be displayed, and to relax the stepwise display of an oblique line or the frickering of a small object. CONSTITUTION:A hiding/appearing processing is executed by the first and second scan lines. The first scan line is corresponding to the conventional scan line, and the second scan line is set between the first scan lines. Data processed by the respective scan lines are processed with double accuracy in comparison with the processing only by the first scan line, stored in the first and second memories and afterwards used for preparing video signals. The video signals corresponding to the respective scan lines are mixed by a mixer circuit 10. |
