Back in the stone ages when web cameras were still becoming a ‘thing’, IBM partnered with Xirlink to produce a line of webcams. USB bandwidth is limited to 12 Mbps; however cameras generate huge amounts of data. Experiments show that this camera sends compressed data. However at least one person has it, so he captured some debugging data that was enough to activate this connector and see the externally provided image. Model 4 has some packet structure too, but I can’t figure it out. No part of this document may be reproduced or transmitted in any form or by any means, electronic or mechanical, including photocopying. The driver does not report true colors with Model 3 cameras.

Camera assembly, top Camera assembly, bottom Sensor board with lens Sensor chip: Caera you will see that the driver and device are now working properly.

Otherwise I will need to ask you about some of that data and we both just lose time. However at such small image sizes the compression is not that necessary.

Usually 0 or 1, used to determine the direction of the transfer. Or you can capture the entire adjustment sequence with the “Capture” button. But I have never installed it. I think, all new NetCameras that you can now buy are of that non-working variety. These have all of the features you’d expect from the 90’s, including slow frame rates, a caemra of x of resolution and the the characteristic compression algorithms every digital footage from the 90’s used.

Each frame is prefixed with several bytes of frame marker which is not part of frame data. To calculate the RGB value for any given pel, you only ‘know’ the color at that pel, and must interpolate the other two colors.

Below I show what models have been spotted in the wild, and which of those are supported: Downloads Support for all models 1, 2, 3, 4 is included in the camra that ships with Linux kernels starting with 2.

BMPs with these cameras if you xirljnk a 90’s looking picture for your I don’t even have all models of cameras! This driver is based on reverse-engineering of the communication protocol and is full of guesswork.

Lens is mounted in a plastic housing secured to the sensor board with two screws. Compressed data only, see note.

Tips for Taking Good Pictures. Maintainers and Projects The most current version of the driver is in the Linux kernel tree.

Anyway, I hope this helps. Nature of returned data is not known for sure, however observations hint that some returned fields carry white balance information in Model 4 cameras. The NetCamera Pro has a very similar part number.

Colorspace conversion Here is some useful information about colorspaces and encoding methods: However this is still very experimental code. You can change the focus by rotating the lens of the camera. To open the Camera window.

I’ve been playing around with a model 2 camera and have discovered that the data format for resolutions at and above x may be different than what you have documented.

It produces the “snowy” image – random colored streaks, they apparently represent compressed image. Frame markers for different video sizes. I do not know how to decode this data, and as such I can’t do anything with it.

It makes my model 2 run better. They share the same USB identification Frame markers Camera sends continuous stream of frames. If you have a generic USB trouble, such as host controller errors, then visit Linux-USB Web site and there you will find addresses of linux-usb-users mailing list.
