ASX340AT_16 Datasheet, PDF (12/54 Pages) ON Semiconductor – 1/4‐inch Color CMOS NTSC/PAL Digital Image SOC

ASX340AT
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.
