Figure 1

In general, the maximum frame rate for the A602fc camera increases as the size of the

AOI decreases because the frame readout time decreases when less information has to be

transmitted. Formula (4) shows the exact relationship (the denominator is the frame

readout time).

maximum frame rate (in fps) =

(AOI Height 3) 15,28µs

+×

(4)

For example, a height of 240 pixels leads to a maximum frame rate 269 fps.

In summary the maximum frame rate depends on the shutter time, the AOI and the bytes

per packet. Use your AOI and exposure time settings to calculate a result in each of the

three formulas below. The formula that gives the lowest value, will determine the

maximum frame rate for the given settings.

Frame rate based on the exposure time

maximum frame rate (in fps) =

maximum exposure time (in µs) 128 µs

(5)

Frame rate based on the frame readout time

maximum frame rate (in fps) =

(AOI Height 3) 15,28µs+×

(6)

Frame rate based on the frame transmission time

maximum frame rate (in fps) =

packets per frame x 125µs
