6.8 Frame Rates
Frame rates from the STH-MD1/-C depend on two factors: decimation and
the number of image lines in a subwindow. It does not depend on the
length of a line, since the CMOS imagers always use the same time to
output a line, no matter how many pixels it contains.
Table 6-1 shows the frame rates for maximum frame sizes in each of the
decimation modes. To calculate an actual frame rate, divide the frame rate
by the fraction of lines in the actual subwindow. For example, at
decimation x2, a subwindow of size N x 240 would have a frame rate of 53
fps (26 / (240/512)).

x2 (644 x 512) 25
