Note
A
Request
in the mvIMPACT Acquire API represents a buffer where an image with the current device
configuration is captured into. In order to avoid losing images at a high FPS, it's recommended to increase
the number of these request buffers (i.e. '
RequestCount'
in '
SystemSettings'
, by default
the value is set to 4 for MATRIX VISION USB2.0 cameras), so that the driver can continue capturing
image data even if the host application is sometimes slower at processing an image than the camera at
transferring one. As a rule of thumb, the number of capture buffers should be configured roughly within
the range of FPS/2 and FPS/5. In the following test, the
RequestCount
is set to 20 which is roughly
FPS/5.
