Exp1 = 7.2 µs to 274.9 ms (input in units of seconds)
1H = 7.2 µs to 237.6 µs
Exp2 = ROUNDUP (Exp1 / 1H) * Round up to integer
Hn1 = Number of horizontal lines
Output bit depth BW = Interface band width
16 bit 167 473 152
12 bit 223 297 536
8 bit 334 946 304
Vn1 = Number of vertical line
Vn2 = Vn2 = (Vn1 + 6) / 2 + 2
Vn3 = ROUNDUP (Hn1 * (Vn1 + 6) / BW / 1H)
