Scout S Handset HS-1
Handset For Advanced Camera Control
The Scout S Camera system has been designed to allow access to advanced functions within the camera. The
advanced functions allow the user to manually set up the camera to specific conditions where the cameras
automatic setting may not quite match what the user desires.
The HS-1 eighteen key Handset gives control over lens functions such as Zoom, Focus, Aperture and Iris.
Internal camera functions are accessable too, Shutter Speeds, Wide Dynamic Range on/off, Auto focus on/off,
Automatic Exposure on/off, Digital Zoom and Brightness can be adjusted and saved using the HS-1 Handset.
In testing the HS-1 Handset is connected between the Scout S Camera head and its supply source, typically
a Shielded Battery Pack, the Scout S Camera is adjusted for the desired picture and the setting is saved using
the Custom Preset button. The HS-1 Handset is then removed and the power source reconnected so EMC Testing
Applications include heads up display testing, LCD displays, Aircraft display panels and Car dash boards.
The Zoom function will allow the user to manually Zoom in and out. At the end of the optical zoom the
Digital Zoom will engage. The Digital Zoom when used with the optical Zoom will give up to 324 times Zoom.
The overall resolution will deteriorate as the effective picture elements (pixels) are progressively reduced
at the extreme end of the Digital Zoom.
Focus On / Off
Auto focusing can be enabled using the Focus on/off function, the minimum focus distance is 10mm at the
optical wide end and 1500mm at the optical tele end and is independent of the digital zoom. The Auto Focus
function automatically adjusts the focus position to maximise the high frequency content of the picture in
a centre measurement area taking into consideration the high luminance and strong contrast components. The
system can be set back to manual focusing if required. Near and far focusing can be achieved by using the
allocated buttons when using manual focusing.
Auto / Manual Exposure
In full Auto Exposure mode the Iris and Gain are automatically varied and the shutter speed is fixed at
50Hz(PAL) or 60Hz(NTSC).
Auto / Manual Exposure
In Manual Exposure mode the Iris, Shutter and Brightness functions can be accessed.
The variable shutter has 16 speeds varying from 1/1 to 1/10,000 sec. The shutter can be varied to
eliminate or minimise flicker of the Device Under Test. For example the
Shutter would be set to 1/100 for NTSC in Countries using a 50Hz power supply and 1/120 for PAL in
Countries using a 60Hz power supply. More detail on available shutter speeds can be seen in the Specification
The Iris can be freely set by the user in 18 steps from F1.35 through to close. When in Auto Exposure the
shutter speed and camera gain are set automatically as the Iris is adjusted. Iris adjustment is used when
varying light conditions are encountered.
The Bright control function adjusts both Gain and Iris using an internal algorithm, according to a
brightness level freely set by the user. Exposure is controlled by gain when dark and by iris when bright.
Only when the Auto Exposure mode is switched to Full Auto or Shutter Priority, can you select Bright.
The Aperture Control is a function which adjusts the enhancement of the edges of objects in a picture.
There are 16 levels of adjustment, starting from ‘no enhancement’. When shooting text this control may help
by making the text ‘sharper’.
Wide Dynamic Range Mode
The Wide Dynamic Range mode is a function that divides the Image into several blocks and correcting blocked
up shadows and blown out highlights in accordance with the intensity differences. It enables the user to obtain
images in which portions ranging from dark to light can be recognised, even when capturing a subject with a
large intensity difference that is backlit or includes extremely light portions.
In the Scout S Camera head a CCD for shooting a wide dynamic range is employed, and an image processor
combines a long exposure signal (normal shutter) and a signal of the high intensity portions obtained by a
short exposure (high speed shutter) to achieve images with a Wide Dynamic Range.
When all the changes are made and the picture is as desired the Custom Preset function can be selected,
the camera will save the settings and the camera will start up with these settings every time the camera
is switched on.
When activated the On Screen Display (OSD) displays any selected functions current status, for example the
level of zoom will be displayed as a bar in the top left hand corner of the screen. Once the desired functions
have been ‘set’ the display can then be switched off as desired.
