java webcam adjust shutter speed

Question

I want to (manually) adjust the "shutter speed" of my webcam with Java code.

1. Is it possible to do this (with java) ?
2. How do I realize it ?

Extra info:

• Windows vista and NetBeans IDE 7.3.1
• Webcam : Logitech webcam pro 4000
• Driver : Quickcam v11
• Language : java
• Library : LTI-CIVIL with example code for image capturing
• I think I need to adjust somewhere the time between the command for the camera to collect light and stop collecting light. (half thinking of an SLR camera).

Answer 1

There are certain available API's that can be used to control your webcam using java.

• Java Media Framework (JMF)

The Java Media Framework API (JMF) enables audio, video and other time-based media to be added to applications and applets built on Java technology. This optional package, which can capture, playback, stream, and transcode multiple media formats, extends the Java 2 Platform, Standard Edition (J2SE) for multimedia developers by providing a powerful toolkit to develop scalable, cross-platform technology.

• Freedom for Media in Java (FMJ)

FMJ is an open-source project with the goal of providing an alternative to Java Media Framework (JMF), while remaining API-compatible with JMF. It aims to produce a single API/Framework which can be used to capture, playback, process, and stream media across multiple platforms.Since FMJ is API-compatible with latest JMF, you may use existing JMF codes and run them.

• Xuggler

Xuggler is the easy way to uncompress, modify, and re-compress any media file (or stream) from Java. This is more widely used for manipulation of media files and related operations.

You can refer the following links:

• Java Media Framework
• Freedom for Media in Java
• Xuggler

You can find tons of tutorials on them. I'm sure you can figure out an efficient way to control the shutter speed of your webcam using any of these API's. :)
