Free quickcam software for linux

QuickCam VC is a video4linux driver for the Connectix QuickCam VC. This project is intended to provide a linux driver only, it is not intended to (and cannot) substitute Connectix/Logitech Windows drivers.
When Logitech will develop a Linux driver for that cam, the authors of this project will be very happy to live them the scene.
This software is a result of a large work amount of identification/intuition outside the usb port, and it isnt based on Logitech programming documents. So this driver can damage your QuickCam.You can use it at your own risk. Unfortunately there isnt free Logitech specifications about the webcam.
Enhancements:
- Adds support for recent 2.6 kernel versions

Gqcam is a Linux clone of the QuickPict software that comes with the QuickCam. Originally it was written using GTK+ for the frontend, Alex Belits qcread for the backend, and a bunch of C to tie it all together.
It still uses GTK+ for the frontend, but as of version 0.2 it uses the Video4Linux interface as a backend. To compile it you will need GTK+, a Quickcam (one of the old greyscale parallel port ones), and a computer running Linux with Video4Linux support for the Quickcam compiled in or as a module.
It is currently fairly early in development, and now works with both the color and greyscale QuickCam. No, that doesnt include the QuickCam VC or any other ones (that I know of). Unfortunatly, Logitech/Connectix dont want to let us know how their new cameras work..
Main features:
- Brightness Control
- White Balance Control
- Contrast Control
- 3 Size Settings
- 2 Depth Settings
- Freeze Picture
- Snap Picture (saves in png, ppm and jpeg format)
- Command-line interface (good for webcam use)
- Snapping on a timer
- Support for the greyscale and color Quickcam, as well as CPiA based cameras and most any other driver that supports the read() command
The cameras I have gotten gqcam to work with or have had other people tell me it works with are:
- Greyscale Quickcam
- Color Quickcam
- Anything listed below this line I have not tested and know very little about
- Ezonics EZcam
- Creative Web-Cam II
- Philips USB PCVC675K
- Webcam III
- TerraCAM USB
- Plustek OptiCam 300U

Improv is a tool for basic real time image processing at low resolution, e.g. suitable for mobile robots.
Improv program has been developed for PCs with the Linux operating system and runs under X Windows.
Improv works with a number of inexpensive low-resolution digital cameras (no framegrabber required).
Main features:
- Modular design, allowing for easy integration of new functionality.
- Image processing operations are contained within plugins, compiled as statically
- linked files (.so), which can be loaded and unloaded at run time.
- Improved support for still image sequences.
- An abstract Camera class, simplifying the creation of new camera drivers.
- A completely customisable interface, allowing for complex image processing sequences.
- Written using the QT Windowing library.
- Portable autoconf/automake build scripts.
Improv also includes support for the following cameras:
- Quickcam grayscale camera (parallel port) [no longer sold]
- Make sure to set the protocol of your parallel port correctly (boot-up setting to either ECP or EPP should work).
- Quickcam Color V2 camera (parallel port) [no longer sold]
- Sorry, none of the newer QuickCams work - Connectix/Logitech refuses to disclose the low-level interface.
- Various web cameras with cpia driver, e.g. ZoomCam
- Video 4 Linux cameras
- and preliminary support for Video 4 Linux 2 cameras.
Improv displays the source image (from either a still image or a live camera) in the first window, while subsequent image operations can be applied to this image in five more windows. For each sub-window, a sequence of image processing routines may be specified.

Lluzhionne is a very configurable Webcam program that can apply randomly selected captions, dates, and filters to images before uploading them.
Lluzhionne project comes with a default set of filters that use NetPBM and ImageMagick; others can be easily added. Lluzhionne can upload images using SCP.
It supports Casio digital cameras, YUV420P Video4Linux devices, and grabbing images supplied by an external Webcam program.
It does not require X11. It has been tested using the Casio QV-10A digital camera and the Phillips (pwc driver) Logitech QuickCam Pro 4000.
Enhancements:
- Support for at least some cameras supported by gphoto2 has been added (and tested with an "iClick Xtreme" USB camera).
- Sending a running Lluzhionne a SIGHUP now reloads its config file.
- SIGINT is now properly caught.
- Support for layering additional filters atop the image (and any captions) with a --overlay option has been added.
- A verbose option has been added.
- Lluzhionne no longer attempts to upload blank output files if an error occurs.
