.SH NAME
sonic-snap \- webcam application for sn9c102 devices.
.SH SYNOPSIS
.B sonic-snap 
.RI [ options ] 
.br
.B sonic-snap-gui
.RI [ devicefilename ]
.RI [ width\ height ]
.SH DESCRIPTION
\fBsonic-snap\fP is a program that captures images and movies from an sn9c102 camera. It requires a kernel module for the device.
.PP
The gui version can display histograms, and output mpeg video.
The commandline version simply captures one or more images, and exits.
.SH OPTIONS
.B gain=[0.0..1.0]
.br
Higher gain setting gives brighter images.
.sp 2
.B normalize=[0|1]
.br
When set to 1, the darkest pixels in the captured image will be mapped onto black, and the lightest pixels to white.
.sp 2
.B autogain=[0|1]
.br
Automatically set the gain based on the histogram of captured images.
.sp 2
.B compression=[0|1]
.br
When set to 1, a higher fps can be reached, at the cost of artefacts in the image (bug in decompressor code).
.sp 2
.B count=[1..n]
.br
The number of images to capture.
.sp 2
.B skip=[1..n]
.br
When high, time-lapse photography is performed.
.sp 2
.B prefix=xxxx
.br
The prefix for writing to disk. Captured images will be called xxxx0000.ppm, x0001.ppm, ...
.sp 2
.B device=/dev/video0
.br
The videoforlinux2 device to use.
.sp 2
.SH EXAMPLES
sonic-snap gain=0.5 normalize=1 autogain=0 compression=1 count=1 skip=1 prefix=sonicsnap device=/dev/video0
.sp 2
sonic-snap-gui /dev/video0 352 288
.sp 2
.SH BUGS
Compression induces artefacts, due to unknown huffman codes.
This is a bug in the decompression library.
