camera1394
[Drivers]

Collaboration diagram for camera1394:

The camera1394 driver captures images from IEEE1394 (Firewire, iLink) cameras.

Compile-time dependencies

libraw1394
libdc1394_control

Provides

camera

Requires

none

Configuration requests

none

Configuration file options

port (integer)
- Default: 0
- The 1394 port the camera is attached to.

node (integer)
- Default: 0
- The node within the port

framerate (float)
- Default: 15
- Requested frame rate (frames/second)

mode (string)
- Default: "640x480_yuv422"
- Capture mode (size and color layour). Valid modes are:
  - "320x240_yuv422"
  - "640x480_mono"
  - "640x480_yuv422"
  - "640x480_rgb"
  - "800x600_mono"
  - "800x600_yuv422" - will be rescaled to 600x450
  - "1024x768_mono"
  - "1024x768_yuv422" - will be rescaled to 512x384
  - "1280x960_mono"
  - "1280x960_yuv422" - will be rescaled to 640x480
  - "FORMAT7_MODE0" - only available with libdc1394 >= 2.0
- Currently, all mono modes will produce 8-bit monochrome images unless a color decoding option is provided (see bayer).
- All yuv422 modes are converted to RGB24

force_raw (integer)
- Default: 0
- Force the driver to use (slow) memory capture instead of DMA transfer (for buggy 1394 drivers).

save (integer)
- Default: 0
- Debugging option: set this to write each frame as an image file on disk.

bayer (string)
- Default: None.
- Bayer color decoding options for cameras such as the Point Grey Dragonfly and Bummblebee. Option activates color decoding and specifies the Bayer color pattern. Valid modes are:
  - "BGGR"
  - "GRBG"
  - "RGGB"
  - "GBRG"

method (string)
- Default: None (or "DownSample" if bayer option is specified)
- Determines the algorithm used for Bayer coloro decoding. Valid modes are:
  - "DownSample"
  - "Nearest"
  - "Edge"

brightness (string or unsigned int)
- Default: None
- Sets the camera brightness setting. Valid modes are:
  - "auto"
  - any suitable unsigned integer

exposure (string or unsigned int)
- Default: None
- Sets the camera exposure setting. Valid modes are:
  - "auto"
  - any suitable unsigned integer

shutter (string or unsigned int)
- Default: None
- Sets the camera shutter setting. Valid modes are:
  - "auto"
  - any suitable unsigned integer

gain (string or unsigned int)
- Default: None
- Sets the camera gain setting. Valid modes are:
  - "auto"
  - any suitable unsigned integer

whitebalance (string)
- Default: None
- Sets the manual camera white balance setting. Only valid option:
  - a string containing two suitable blue and red value unsigned integers

dma_buffers
- Default: 4
- the number of DMA buffers to use

iso_speed (unsigned int)
- Default: 400
- Sets the data rate of the 1394 bus. Valid rates are 100, 200, 400, 800, 1600, 3200.
  Example
```
driver
(
  name "camera1394"
  provides ["camera:0"]
)
```
