Internal Frame Rate
The frame rate is dependent on the window size, and the exposure times are dependent on
the frame rate. For example, decreasing the frame rate allows for a longer exposure time.
To increase the frame rate decrease the window size. Frame rate takes priority over
exposure time. Maximum exposure time can be increased by lowering frame rate.
Faster frame rates can be achieved using by decreasing the number of horizontal pixels (x,
columns) and / or the number of vertical lines (y, rows).
The following chart shows maximum camera speed in fps for different combinations of
resolutions aspect ratios and sensor bit depths (input pixel size).
In addition, an online frame rate calculator is available from the Falcon2 product page on
the Teledyne DALSA site, here .
