Dealing with the Operating Range in the MultiCam Environment

Besides the LinePitch and EncoderPitch MultiCam parameters, you may have to take care of two additional parameters: PixelClk_Hz and MaxSpeed.

PixelClk_Hz is an inherent attribute of the camera you are using. You will not have to change it, unless you are defining a brand new camera, with a non standard clock frequency. This parameter corresponds to the pixel frequency of the camera.

MaxSpeed is set by default to the speed limit of the camera. The limit line frequency is linked to the camera attributes in the following way:

You will change the MaxSpeed parameter only if the default value does not suit your needs.

Once a maximum line frequency is chosen, the MultiCam environment computes for you the corresponding minimum line frequency.

This value is returned through the read-only parameter MinSpeed.

You will use this value to appreciate the operating range of the rate encoder, and determine if it covers your requirements in term of web speed variation.

If your application is working significantly lower than the speed limitation imposed by the camera, it may happen that you have to lower the maximum line frequency.

All the MultiCam parameters representing frequencies are expressed as an integer number of Hertz.
