Q3 – Operation Manual

Detail

Detail will increase or decrease the picture sharpness but will also affect the noise in the

picture.

Chroma affects the amount of colour saturation in the picture. This can be used to good

effect when matching Q3 to other makes of camera.

IR stands for 'Infra-Red' and switches the camera to monochrome and greatly increases the

sensitivity in low light levels. An Infra-Red lamp may also be used to illuminate the viewing

area. Note that when using purely infra-red light to illuminate a scene the focus may not be

correct. An option in the OSD screen can be set to correct the focus in this case. Select

OSD>Mode>AutoICR>FocusAdj ON/OFF to change this setting. Note this should only be

changed when the lighting is entirely from an Infra-Red lamp. There is also an 'Auto IR'

setting which will enable the camera to automatically switch to IR when the light level drops

to a point where the 'auto gain' has increased beyond 36db. The 'Auto IR' option is only

available in 'Auto Iris' mode.

AWC mode sets how the colour of the camera is controlled. The default is 'Manual' which

gives control to the red and blue colour knobs on the RCP. Other settings include 'ATW'

which automatically adjusts the camera colour depending on the picture content. Also, fixed

colour settings for 5600k and 3200k lighting types.

Gamma controls the picture brightness in dark areas of the image. A lower gamma setting

increases the brightness in dark areas and a high gamma value reduces the brightness in

dark areas. The picture noise is increased for low gamma settings.

There are three settings here On, Off and Auto. The effect is to decrease the picture noise

using a 'Median Filter' at the expense of a slight reduction in resolution. The 'Auto' setting

will automatically insert the noise filter as the gain level is increased.

The Iris area setting is used by the 'Auto Iris' function to determine which area of the picture

is used to set the auto iris level. As the up/down function buttons are pressed, a brief

display of a rectangle on the screen will show the area selected for the auto iris adjustment.

Iris speed sets the speed at which the iris responds when in auto mode. This will probably

need to be 'Slow' when there is a lot of light and the iris is nearly closed to prevent 'hunting'.
