Chapter 7 Image Acquisition

7.1 Set Frame Rate

Frame rate refers to the image number that is acquired by the camera per second. The higher
frame rate, and shorter time used for image acquisition will be. The following 4 factors determine
the camera's frame rate in real-time.
 Frame readout time: the frame readout time is related with camera's sensor performance and
image height. The lower the image height and less the frame readout time, and the higher the
frame rate will be.
 Exposure time: if the reciprocal of max. frame rate that the camera supports is t, and when the
configured exposure time is larger than t, the less the exposure time, the higher the frame rate
will be. When the configured exposure time is less than or equal to t, exposure time will not
influence the frame rate.
 Bandwidth: the larger the bandwidth, the higher the frame rate will be.
 Pixel format: the more bytes pixel format occupy, the lower the frame rate will be.
Click Acquisition Control > Acquisition Frame Rate, enter Acquisition Frame Rate, and check
Acquisition Frame Rate Control Enable.
 Here we take KAYA CoaXPress frame grabber client software as an example. For specific
graphical user interface, refer to the actual interface you use.
 True stands for enabling Acquisition Frame Rate Control Enable and false stands for disabling.
 If the camera's current frame rate is smaller than configured frame rate, and the camera
acquires images according to current frame rate. If current frame rate is larger than configured
frame rate, and the camera acquires images according to configured frame rate.
