12.1 wxPropView 81
• SingleFrame ("Single Snap")
The frame rate depends on
• the camera,
• the pixel clock of the sensor and
• the "Acquisition Frame Rate".
If you want to have a fixed frame rate using the "Continuous" mode, GenICam (p. 155) offers the property "Setting
-> Base -> Camera -> GenICam -> Acquisition Control -> Acquisition Frame Rate" (from 5 fps to maximum of
the camera in 0.1 increments). Just adapt this property to your needs.
Alternatively, if you need frame rates below 5 fps, you can use Timers. In the use case Creating synchronized
acquisitions using timers (p. 277), for example, a frame rate of 1 fps is generated.
12.1.1.3.1 Record Mode
It is also possible to record image sequences using wxPropView.
1. For this, you have to set the size of the recorder in "System Settings -> RequestCount" e.g. to 100.
This will save the last 100 requests in the request queue of the driver, i.e. the image data inluding the request
info like frame number, time stamp, etc.
2. Afterwards you can start the recording by clicking the Rec. button.
3. With the Next and Prev. buttons you can display the single images.
If you switched on the request info overlay (righ-click on the display area and select the entry to activate this
feature), these information will be displayed on the image, too. With the timestamp you can see the interval of the
single frames in microseconds.
