Time Diagram for Image Grabbing
The camera ANPVC 1210 is a black-and-white progressive scan CCD camera. The camera is
suitable for grabbing images of moving objects. The image grabbing is triggered by a signal
from the frame grabber. With a delay of only a few
 s the sensor will be completely exposed
according to the shutter speed (exposure time) you have set. Immediately afterwards the
frame grabber starts the transfer of the digital image signal to the memory of the Im-
agechecker, where it will be processed and evaluated.
There are 30 different settings between 1/15 seconds and 1/12500 seconds available for the
shutter speed. The transfer time for an image from the camera to the memory is about 34ms
for a full image with 1200 lines. This means a maximum image rate of about 30 full images
per second.
When you are using partial scan mode, only a reduced number of image lines will be trans-
ferred and this reduces the transfer time. This helps you to increase the image or inspection
