3.6.2 Changes to the Frame Rate with AOI
In general, the maximum frame rate for A602f cameras increases as the size of the AOI
decreases. However, the maximum frame rate can also be limited by any one of three factors:
• The amount of time it takes to read out a captured image from the image sensor to the
frame buffer.
• The amount of time it takes to transmit an image from the frame buffer to the PC via the
IEEE 1394 bus.
• The exposure time setting.
To determine the maximum frame rate for a given AOI, use your AOI and exposure time settings
to calculate a result in each of the three formulas below. These formulas take your AOI size into
account plus the three factors that can limit the frame rate. The formula that returns the lowest
value will determine the maximum frame rate for the given AOI.
Formula 1 calculates the maximum frame rate based on the sensor readout time:
Where: C = 45.84 µs for monochrome cameras
C = 61.12 µs for color cameras
Formula 2 calculates the maximum frame rate based on the frame transmission time:
Formula 3 calculates the frame rate based on the exposure time:
L
This section applies to A602f cameras only. On A601f cameras, the maximum frame
rate is 60 frames per second in 8 bit output modes or 30 frames per second in 16
bit output modes and does not increase when the AOI feature is used.
