34 / 60 page  DDP 3310B ADVANCE INFORMATION 34 Micronas 3.3.1. Scaler Adjustment In case of linear scaling, most of the scaler registers need not be set. Only the scaler mode, active video length, and the fixed scaler increments (SCINC1 / SCINC2) must be written. For adjustment of the scaler for non-linear scaling, the parameters given in Table 3–4 should be used. An example for “panorama vision” mode is depicted in Fig. 3–4. It shows the scaling of the input signal and the variation of the scaling factor during the active video line. The scaling factor starts below 1, i.e. for the borders the video data is expanded and after it exceeds 1 it is compressed. When the picture center is reached, the scaling factor is kept constant. At the sec- ond border the scaling factor changes back symmetri- cally.
