What is the output format of a webcam? I want to create a microcontroller device which can capture a frame from a USB webcam and I need to know what format the output from the webcam is in.

Thanks in advance.

It depends on the webcam, it can be in RGB, BGR, YUV and various others, even JPEG. You might be better looking for a CCD module that you can interface to your micro rather then a USB solution as you will need to engineer a compatible USB driver as there is no standard for webcams like there is for storage devices (mass storage device).

Something like this: http://www.jrobot.net/Projects/AVRcam.html

Or probably even better: http://www.sparkfun.com/products/8668 (i2c for control, 8bit parallel for data and supports RGB, YUV and JPEG compressed formats)

Depends on the camera, really. But most sensors output in YUV (or YCbCr) and it's variants

Basically in Windows Operating System. When you are using a webcamera it stores the clip in the AVI(.avi) format.

I am using Intext IT-305WC web-cam & using windows xp. I am using a software ( from intex itself ) & its download link is - http://amcap.en.softonic.com/download.

This software provides recording a video in avi format.
