3-5. Shutter speed calculation formula
1. High-speed shutter
• NTSC (L16 = load value)
T = [26210 – (1FF16 – L16) ] × 63.56µs + 34.9µs
• PAL (L16= load value)
T = [31210 – (1FF16 – L16) ] × 64.00µs + 35.0µs

2. Low-speed shutter (Valid during field accumulation mode only)
Shutter speed calculation formula
N = 2 × (1FF16 – L16) FLD
However, "FF" cannot be used as the load value.
