Chroma key (Green Screen)

The chroma-key feature is provided in Phoyo by the “decor format” and the “background (green screen)” filter.

Decor format options

The “Chroma key” background detection mode must be selected and the other settings must be adjusted.

IMPORTANT: You can select the background color (generally green). It must be as closest as possible to the actual background color.

Green screen filter

Ideally the its settings should be set to colorRadius=64 and amount=100. You can then make them evolve according to your actual setup.

IMPORTANT: You can select the background color (generally green). It must be as closest as possible to the actual background color.

How does a photo booth software work

Phoyo is built around these components:

An image acquisition module responsible for producing the input image in the first place by retrieving it from a hardware-based source (webcam or DSLR camera) connected to the photo booth PC
An image processing unit that uses mathematical operations to transform the acquired images and achieve desired results. This can involve image enhancement techniques such as the adjustment of colors, contrast, sharpness, etc or creative retouching such as chroma key, image distortion, etc.
An audio engine that execute algorithms related to the sound reproduction and synchronization
A printing management system that handles communication with printing devices
A payment module that handles communication with the coin devices
A database in which events are logged and from which usage statistics are calculated
A presentation layer that contains the building blocks of user interface and holds the global execution logic of photo booth sessions

We believe

that making it possible for everyone to express themselves through digital photography, with tools that they can own and improve, is the way to go.

A Photo Booth operating Phoyo

Phoyo was installed in 2013 in an unattended photo booth. The booth was built with a PC, a screen, a printer, a webcam and a coin acceptor. It was setup to produce identity photographs. More information here.
