Digital Judging System

The Digital Judging System (DJS)  is a photo competition judging system designed for judging in front of a live audience. Using multiple USB Keypads, judges can cast votes on photographs as they are projected. There are two types of competitions Digital projections, and Print.

DJSDigitalScoring2

With the Digital Judging system you can run an entire projection competition from a single computer. Once all the judges have cast their vote the image score is displayed in the lower right corner of the image. Optionally, the each judge score is also displayed after all votes have been cast. The Digital Judging System will manage the following from a single laptop computer:

  • Projecting digital images onto a screen for judges to cast a vote.
  • Manage the judges voting keypads and scores.
  • Tally results and assist in tie-breaking rounds.
  • Calculate overall top maker and top club scores.

Since the Digital Judging System is managing both the projected image and the judging keypads, scores are directly tied to the image. This ensures that images and scores cannot be out-of-sync.

Merrimack Valley Camera Club has been using the Digital Judging System for real-time judging of our George W. Glennie Nature Salon for the last 5 years.  Setup and judging of almost 1,000 images is a snap with this software.  It makes the actual judging the easiest part of the whole competition.  Our judges are always impressed on how easy it is to use.  I can’t imagine running the Glennie without it.

We also use it for real-time judging of our Carlson Black & White print competition and PSA and NECCC Digital / Projected Image competitions that we host.

USB Hub

Targus 4-Port USB 1.1 Hub PA055U (Black)

  • Form Factor – External
  • Dimensions WxDxH – 3.75″ x 1.66″ x 0.75″
  • Weight – 3.0 oz

I like this hub because it light up when a keypad is attached correctly so you can quickly diagnose any issues. The most common being a judge pulls the keyboard cable and it becomes dislodged.

Short USB Extension Cable

51YZDmERoeL._SL1500_Waltzmart Premium 5FT USB 3.0 Type A Male to Female Extension Cable Cord Wire

  • Brand New and high quality
  • USB 3.0 Type A Male to Female device cables
  • Double-shielded, twisted-pair data wiring minimizes cross talk for error free SuperSpeed data transfer rates
  • Support data transfer rates up to 4.8Gbps
  • Backwards compatible with computer USB 2.0 and USB 1.1 ports
  • Color: Black

Any short extension cable will due, this gives the judges more room to move around while judging. The one thing I like about this cable is that it is black. Other than that any USB extension cable will do. You can tell if you have a USB extension cable as one end of the cable can plug into the other end of the cable.

10m / 33 feet USB 2.0 Active Extension Cable

It should be an Active Extension USB cable, is it exceeds the maximum length for  a standard USB cable. I have had issues with non-active versions.
