7 - 20 PC Camera Module

BisonCap (for 1.3M pixel camera module)

BisonCap is a video viewer useful for general purpose video viewing and testing,

and can capture video files to .avi format.

1. Run the BisonCap program from the Start > Programs/All Programs > Bison-

Cam menu (it is recommended that you set the capture file before the capture

process - see Set Capture File below).

2. Go to the Capture menu heading (if you wish to capture audio check “PC Camera

Audio Setup (all camera modules)” on page 7 - 18) and select Start Capture.

3. On the first run of the program (if you have not set the captured file) you will be

asked to choose a file name and size (see the sidebar - Pre-Allocating File

Space) for the captured file. Click Start Capture again.

4. Click OK to start capturing the video, and press Esc to stop the capture.

5. If you wish to, you may go to the File menu and select Save Captured Video

As..., choose a file name and location, and then click Open (you can view the file

using the Windows Media Player).

Set Capture File

In the BisonCap program you will only be asked to set the capture file name on the

first run of the program. When you run the program the next time the file will auto-

matically be overwritten with the newly captured file. To avoid overwriting files you

can go to the Set Capture File.. option in the File menu, and set the file name and

location before capture. Set the name and location then click Open

(you can choose

Cancel to ignore the file size if prompted).

Pre-Allocating File

Space

You may pre-allocate the

file size for the capture file

in the

BisonCap

pro-

gram. You can choose to

ignore this by clicking

Cancel

Pre-allocating space on

the hard disk can improve

the capture quality (par-

ticularly of large capture

files), by reducing the

amount of work the hard

disk has to do in finding

space for the video data

as it is being captured.
