NAME
qcam, xqcam - get pictures from B&W Connectix QuickCam(tm)
SYNOPSIS
DESCRIPTION
sqcam is a program that displays the output of a QuickCam on a system using svgalib.
OPTIONS
- -sscale
- scale can be 1, 2, or 4. It specifies what fraction of the QuickCam data should be discarded. scale of 1 indicates that all the data should be sent. scale of 2 indicates that half of the pixels on each line and half of the lines should be discarded, resulting in 1/4 as much data being transferred. scale of 4 likewise means a fourfold shrinking in each direction.
- -Bbpp
- Bits per pixel. Valid values are 4 (giving sixteen shades of gray) and 6 (giving 64 shades of gray).
- -bbrightness
- Exposure time. Useful values are 1-254, with low numbers indicating short exposures (for use in bright light) and high numbers indicating long exposures (dim light). brightness of 255 puts the Cam in "bulb mode", which is not useful with qcam and xqcam.
- -ccontrast
- contrast is normally set at 104. Low numbers indicate low contrast. Valid values are 0-255.
- -h
- Print usage information.

BUGS
Autodetection is very brittle.
The new Color QuickCam is not handled with this software, although there are Color Cam drivers available from the web site.
The wide-angle lens of the QuickCam gives an ugly barrel distortion. Michael Herf has written warp(1) to fix this, but since warp(1) doesn't know what part of the CCD is in the image, it only works on images whose center is the center of the CCD.
