Capture high resolution camera / webcam images from browser

I need a Java applet / flash file to capture high resolution images in a browser based application. 1. Check the resolution of a connected camera 2. Capture live still image (Potential enhancement -> capture video) I now have a flash file (Actionscript 2 SWF, decompiled sources) to capture images (usb camera / webcam) and upload to server. It is working perfectly but is not the highest possible resolution. I need to enhance this script OR get some other way to detect the resolution of a selected camera connected to the client browser machine and upload pictures in the best resolution. If there is a ready solution, I maybe able to work with it. Will need to update the piece where my code calls a particular PHP controller responsible for storing and updating the relevant records in database. Posted similar project earlier but most responders mentioned that the highest resolution based on connected camera may not be possible in flash, hence the addition of Java applet as an acceptable alternative solution. Thank you!! M
