NOTE: This experiment/code is obsolete and no longer supported,
unless you are a developer trying to understand the quickcam express, go away

OpenQCE stands for "Open QuickCam Express", it intend to drive your Logitech Quickcam Express from OpenBSD userland (using ugen(4)). The Logitech Quickcam Express is a little USB webcam with a 360x296 CMOS sensor (Agilent/HP HSDC1000) and an undocumented STV0600 ASIC. OpenQCE is currently only compatible with one version of this product as I only own one Quickcam Express, I might add support for other webcams in the future. OpenQCE is a cheap and ugly piece of code, I welcome generous donations in good BSD-Licensed code, patches or money.

documentation

I got most of my information from reverse-engineering and reading websites about similar drivers or similar webcams.

faq

What can OpenQCE do:

• Displays what your webcam sees, live with libSDL and X11 or on sequences of pnm files (openqce_shot and openqce_sdl).
• You can specify a delay and let openqce run in the background, it will shoot every x seconds (-p).
• You can select three resolution : 376x312 (with borders), 360x296 and 352x288 (-s).
• You can see raw data from the sensor or a fast interpolated image (-f).
• You can dump all the registers of your webcam (openqce_dump).

What OpenQCE can't do:

• Have a dynamic gain/exposure control.. or even a manual one. For right now it's static and unpractical, it will be fixed in the next version.
• There is no white balance correction.
• It doesn't feature a interpolation-sharpen-killer-filter, picture is good but could be better.
• Save files as .png or .jpg.
• Add text with ttf fonts.
• Interpolate with another png (OSD).
