Output Data Format
The sensor core image data are read out in progressive scan order. Valid image data are
surrounded by horizontal and vertical blanking, shown in Figure 8.
For NTSC output, the horizontal size is stretched from 640 to 720 pixels. The vertical size
is 243 pixels per field; 240 image pixels and 3 dark pixels that are located at the bottom of
the image field.
For PAL output, the horizontal size is also stretched from 640 to 720 pixels. The vertical
size is 288 pixels per field.
