the cropped image on the computer.
Cropping
When the image size is set to 640 × 480 (VGA), you can

image on the computer. Cropping reduces the
transmitting data size and thus the network load, and a
higher frame rate is achieved.
Select On to crop the image, or Off.
Note
Object detection (page 69) operates for an image in the
image size that is not cropped even if Cropping is set to
On.
