I have a situation where I want to take digital photos (snapshots -
not video) of the contents of boxes as they move along on a conveyor.
I'm thinking that a photo would be taken at the same time that I scan
in a barcode that's on the side of the box. I'd then associate the
barcode with the .jpg image file and store it on a computer's hard
drive for later manual viewing.

Does anyone know of a camera that can be set up such that I can take
the picture under computer control and that can then immediately send
the resulting picture to the computer?

Any thoughts or suggestions will be greatly appreciated.

Any webcam can do this, or you could use a frame grabber and any RS-170
video camera. You don't specify resolution, or if color is required, but
you may want to look at www.electrim.com for some reasonably priced USB
2.0 cameras.


Jeff -

Thanks for the link.

I'm beginning to think that maybe going the "frame grabber" route
might be a better way. Do you know of a particular camera and
software that you could recommend?

Yes, the resulting photos need to be in color. I have no idea as to
the resolution that's needed. The idea is for someone to be able to
look at the picture and see what's in the box. I don't even know yet
what exactly it is that they're looking for.

The software that's going to control all this (receive the barcode
from the scanner, trigger the acquisition of the picture and process
and store the picture) will be custom written using Visual basic 6.
I've found an OCX that supposedly does frame grabbing (VideoCapX at
www.fathsoft.com). Would you happen to know of any other software that
I should look at?



Our previous systems used a monochrome camera and I have used both
National Instruments, and Data Translation frame grabbers. They work
well. The new system I am working on will use the Electronic Imaging
USB2.0 camera both for higher performance (resolution and speed) and for
lower cost. It will also be programmed under VB6.0 due to some
constraints on some legacy portions of our system. I will be using their
device drivers.

Is "Electronic Imaging" a brand name? I just googled that and didn't
come up with a camera by that name.
