7.2.4 Window Display
The L1 layer is used to display the captured video graphics. A part or the whole of the captured
graphics can be displayed as the full screen or as a window.
To capture and display video graphics, set the L1 layer to the capture synchronous mode (L1CS = 1).
In the capture synchronous mode, the L1 layer displays the latest frame in the video capture buffer.
The display addresses used in the normal mode are ignored.
The stride of the L1 layer must match that of the video capture buffer. If they do not match, the
displayed graphics have oblique distortion.
Match the display size of the L1 layer with the reducted graphics size of the video capture. Setting the
display size of the L1 layer larger than the capture image size causes display of invalid data.
The L1 layer supports selection of the RGB display format and YcbCr display format. To capture video
graphics, select the YcbCr display format (WYC = 1).
7.2.5 Interlace Display
The graphics captured in the video capture buffer in the WEAVE mode can be displayed in interlace.
Interlace display setting is the same as WEAVE mode setting. Select ‘Interlace & video display’ for
display scan.
Flicker appears in moving video graphics. To prevent flicker, set the OO (Odd Only) bit of the capture
buffer mode register (CBM) to “1”.
