Notes
• JPEG - 768 × 576 is configured by zooming in a JPEG
- 640 × 480 (VGA) image. You may have the
impression that the image resolution is reduced.
• Video output mode (page 33) is set to NTSC + IP or
PAL + IP, or Iris open is On (page 33), superimpose
and privacy masking are disabled regardless of the
settings. The output image size is fixed at 640 × 480
