8.6.4 Partial Scanning
The timing for the partial scan mode in normal continuous mode is shown below.
Vertical Timing
The diagram below provides the vertical timing information.
Frame rate calculation formula
The frame rate can be calculated using the following formula.
In this formula, “Ceil” is round up. And(Top_Dum Partial lines +
Bottom_Dump_line)=3248
Total lines = 59 + Partial lines + 20
Frame Rate (fps) = 1 / (2960 * Total lines * 33.333333 / 1000000000)
Where,
A _line Ceil{(Top_Dum 3)/12}, If Top_Dump_Line is 0, A_line is 0.
B_line Ceil{(Bottom_Dum 3)/12}, If Bottom_Dump_line is 0, B_line is 0.
