Environmental considerations

This section explains how to carry out basic adjustments and simple tests to ensure that you send and receive the best possible image and audio quality when using your Vision 5000.

Iris control and lighting

By default the Vision 5000 camera will use an automatic iris to compensate for changes in lighting. In addition to this feature you may further assist the Vision 5000 to maintain the best possible image quality by paying special attention to environmental lighting and background colours as described below. Remember the Vision 5000 will send live images of yourself and your immediate surroundings.

Avoid direct sunlight on the subject matter i.e. yourself, the background or onto the camera lens as this will create harsh contrasts.

If light levels are too low you may need to consider using artificial lighting. As above avoid direct illumination of the subject matter and camera lens.

When using artificial lighting, ‘daylight’ type lamps will produce the most effective results. Avoid coloured lighting.

Indirect light from shaded sources or reflected light from pale walls, often produces excellent results.

Avoid harsh side lighting or strong light from above, for example: strong sunlight from a window or skylight, as this may put part or all of the subject matter in shadow or cause silhouetting.

If you still have problems with the iris and lighting, manual adjustment of the camera parameters might help - see ‘Camera adjustments’ in ‘Video Input’ menu.

Dim scenes can also be improved by manually adjusting the camera brightness setting.

Background

The appearance of the picture background is very important but easily overlooked. It is important to remember that the camera also shows what’s behind you when in a videoconference. To ensure a suitable background we recommend you consider the following:

Use a neutrally coloured background with a medium contrast and a soft texture, e.g. a plain curtain with no heavy patterns or strong colours that may adversely tint the whole scene.
