2. Overview

2.1. The Videology USB Camera Family

Videology USB Cameras provide a quick and easy means of displaying and capturing high quality video
and images on any USB 2.0 equipped desktop or laptop computer running a supported Microsoft

Designed with flexibility in mind, each camera model has its own distinct advantage, whether speed,
resolution, image quality, sensitivity or price. Because they are USB based, there is no need for a frame
grabber. Instead, a single USB cable provides power, video frames, control and data transfer.

 All cameras share the same simple, powerful API allowing easy migration from one camera to

another.

 SDKs are available for OEMs (for an additional fee).
 Housings: Mechanical design options can be quoted for OEMs

This fixed lens camera family can utilize any CS mount lens. The lens may be changed out for a more
optimal focal length. Varifocal lenses allow a wider range of focal lengths within one lens.

Note: Use a Megapixel lens with the Megapixel 24C7.38USB camera in order to maintain the fu ll
resolution.

OS.

2.2. Contents

This camera package has two CDs in it.

1. SFT-07019-WHQL (WDM device drivers are Microsoft
o or SFT-07019 (Videology Viewer software and USB drivers)

2. SFT-10011 (TWAIN data source)

To check for updated software, please go to www.videologyinc.com/download.htm
The Videology viewer (SFT-07019-WHQL) can operate this camera family without a need for any third

party software. It will auto recognize which camera is plugged in and show the corresponding controls and
features for that camera.

Note: All cameras stream video and have a still capture mode.
Many users wish to utilize a Photo ID card software management platform. In this case a separate TWAIN

driver is needed (SFT-10011). ALL third party software packages allow a camera to be recognized thru
their TWAIN (or Scanner) drop down camera source choices. This TWAIN interface is recommended as the
primary method to integrate with the Videology camera.

If the software photo ID management program has a standards based DirectShow compliant interface, the
camera will work with that interface. However, we have found many third party software platforms do not
conform to DirectShow on all operating systems.

4. Mounting Method

y

The cameras (20K758USB and 24C7.38USB) are fitted with a ¼-twenty screw thread so that any
common tripod can be used.

The 20K758USB-SYS has a unique stand
that integrates the camera with a stand that
can withstand a 40 degree tilt and still
stabilize upright. The camera cannot
dissemble from the stand, as it is totally
integrated with cabling that threads within
the assembly.

The cable neatly emerges from the base of
the stand (eliminating the potential to
entwine around a tripod’s legs or to pull the
camera down if accidentally twisted).

Tabs are provided to attach the base of the
stand to a table, thereby fully immobilizing
the stand.

8.1. MODELS 2XK1XXUSB-C

To launch the viewer software, simply click on the Videology Icon on the Desktop. A window will appear
displaying the camera image.

8.1.1. Using the Control Panel

Clicking on the Control option on the menu bar will display the control panel. The control panel can be
used to make changes to the camera settings. The various control features are discussed in more detail in
the following pages.

Revision: A Preliminary Page 16 of 42

8.1.2. Shutter Mode

For this type of camera, the shutter speed refers to an electronic shutter, which determines the length of
time over which charge is accumulated on the image sensor. There is no physical shutter.

In low-light conditions, a slow shutter speed (long integration time) is required in order to get a quality
image. However, if there is significant motion in the scen e, a slow shutter speed will result in significant
blurring of the image, and a faster shutter speed will be needed to get a clear sharp image.

The shutter speed of Videology USB cameras can be varied from 1/50 second to 1/10000 second.
There is an automatic setting (Electric Iris), in which the shutter speed is adjusted automatically according

to the overall light level.
There is also “flickerless” shutter speed, which is used to prevent fluctuations in image brightness when

operating under fluorescent lighting.

8.1.3. Back Light Compensation (BLC Control)

Under normal lighting conditions, with the Electronic Iris control activated, the camera will automatically
adjust the image brightness so that all parts of the image are visible.

However when the background illumination is very bright – for example, when someone is standing in
front of a window – the shutter speed will automatically reduce which will cause the foreground image to
appear darkened. Faces may appear as if in silhouette making it difficult to see any detail.

In this situation, Back Light Compensation (BLC) can be used to increase the brightness of certain parts of
the image.

Back Light Compensation effectively limits the area of the screen in which the AGC operates, thus
ensuring that details within the area will not be lost. As a consequence, regions of the image outside of
the BLC area may become very bright and washed out.

To enable BLC simply click on the BLC Check box.
To display and/or change the BLC area, click on the On Screen Display box.
An 8 x 8 grid will appear over the image with

a red box drawn around the active BLC
window. To move the BLC window, you can
either drag it with the mouse, or enter the X
and Y co-ordinates in the control panel.

The size of the BLC window can vary in both
size and shape. The BLC window controls the
size and the BLC window posn controls
where the BLC area is within the grid.

The level of BLC can be adjusted using the
WEIGHT function on the BLC control panel.

Doc # INS-07019 rev A Issue Date: 07/22/2011
Revision: A Preliminary Page 17 of 42

NOTE: Videology supplies the camera's default option in BLC with a center weighting.
BLC will only function when the shutter speed is set to “Electric Iris.”

The effect of Back Light Compensation is shown in the following images.

Back Light Compensation OFF (top image) and Back Light Compensation ON (Bottom Image).

Revision: A Preliminary Page 18 of 42

8.1.4. Mirror Mode

The mirror mode option is simply used to provide a mirror inversion of the image. This feature is used
when the camera is viewing the subject through a mirror.

8.1.5. Reset

The Reset feature is used to restore all the settings to the factory default values.

Revision: A Preliminary Page 19 of 42

8.1.6. Edge Enhancement

Edge enhancement is used to make the edges of lines appear sharper and more distinct. It gives the
appearance of increased resolution, but in reality the resolution is determin ed purely by the number of
pixels, and is fixed.

The effect of edge enhancement is illustrated below.

Edge Enhancement OFF (top image) and ON (bottom image)

Revision: A Preliminary Page 20 of 42

8.1.7. Manual Gain

Manual Gain provides a means of controlling the overall image brightness.

8.1.8. White Balance (WB) Mode

Under varying lighting conditions, (sunlight, fluorescent lighting etc) the perceived color of objects will
change. This is true for the human eye and also for the video camera.

The color spectrum of a light source varies according to its’
temperature. A tungsten lamp for example operates at a
relatively low temperature of about 2800K (~3000˚C)
whereas the sun has an equivalent color temperature of
about 5500K (~5800˚C).

We typically classify light sources by their “color
temperature” which is a measure of the temperature of a
perfect black body that would radiate light with the same
spectral (color) content.

As the color temperature of a light source increases, the
spectrum of the emitted light moves from red to blue. Thus
a piece of white paper viewed under a tungsten lamp would
have a slightly reddish hue, whereas when viewed under
sunlight it would appear to be slightly blue by comparison.

Fluorescent lamps operate very differently from
incandescent lamps, and can have color temperatures
ranging from 3000K to 5000K.

The White Balance control function is used to change the
color settings within the camera so that white appears white.

There is an Automatic White Balance mode, in which the
camera automatically adjusts according to the scene
content.

In addition to the automatic white balance, there are three
fixed white balance settings, WB mode1, WB mode2 and WB
mode3.

Mode 1 is user configurable, using the Rgain and Bgain controls within the control panel, and can be
used to give the desired color reproduction under specific lighting conditions.

Modes 2 and 3 are preset for indoor (fluorescent lighting) and Outdoor (sunlight) use.

8.1.9.1. Isochronous and Bulk transfer modes.

There are two basic transmission modes for data on the USB bus. These are referred to as Isochronous
and Bulk Transfer.

Under the Isochronous Transfer mode a fixed bandwidth (up to a maximum of 40% of the total
available) is assigned to the camera, ensuring a minimum speed of transmission. In this transfer mode,
there is no error correction and any dropped data will not be re-transmitted. This mode is typically used
for time sensitive data such as video and speech where there is little utility in repeating lost information.

Under the Bulk Transfer mode there is no fixed (upper or lower) limit to the available bandwidth, and
data is simply transmitted whenever the bus is av a ilable. Bulk transfer includes error correction and
dropped data packets, which are retransmitted.

Doc # INS-07019 rev A Issue Date: 07/22/2011
Revision: A Preliminary Page 23 of 42

If multiple USB cameras are operated simultaneously, it is possible that th e data rate from the camera will
be reduced; resulting in a slower frame rate for the displayed image, and under this situation the
isochronous display should be used.

If only one camera is being used, then the bulk transfer mode will probably provide the fastest display.
NOTE:

When changing the transfer mode from Isochronous to Bulk, it is necessary to close the application,
unplug and reconnect the camera, and restart the application.

8.1.10. Still Image Capture (Snap Feature)

The Image Snap feature is located under the File menu and is used to acquire and store still images from
the video display. The “Set Snap Image Folder…” button is used to change the location where snapshot
images will be saved. The files are saved to the user’s desktop by default. The files are stored as Bitmap
(BMP) files.

8.2.1.3. Shutter Speed

The camera’s shutter speed is analogous to the shutter speed of a conventional camera, although for a
solid state imager there is no physical shutter. For this type of camera, shutter speed refers to an
electronic shutter, which determines the length of time over which charge is accumulated on the image
sensor.

In low light conditions, a slow shutter speed (long integration time) is required in order to get a good
quality image.

Shutter speed for the 24B1.3XUSB-C camera can be varied from 0.6 second to 1/5000 second. The
camera utilizes a rolling shutter, which operates in a fashion similar to a f ocal plane shutter on a
conventional camera.

With this type of shutter, different parts of the sensor are exposed at different times, which can result in
distortion of moving objects.

Note: Faster shutter speeds should not be used when operating the camera under fluorescent lighting. The
intensity of the light varies at the AC line frequency (60Hz) and causes dark bands to appear across the
image.

8.2.1.4. Mirror and Flip Mode

The Mirror and Flip options are used to create images which are mirrored about the Vertical and Horizontal

8.3.1.3.1. Shutter Speed
The camera’s shutter speed is analogous to the shutter speed of a conventional camera, although for a

solid state imager there is no physical shutter. For this type of camera “shutter speed” refers to an
electronic shutter, which determines the length of time over which charge is accumulated on the image
sensor.

In low light conditions, a slow shutter speed (long integration time) is required in order to get a good
quality image.

This camera’s shutter speed can be varied from 1/15 sec. to 1/120 sec. The camera ut ilizes a rolling
shutter, which operates in a fashion similar to a focal plane shutter on a conventional camera.

With this type of shutter, different parts of the sensor are exposed at different times, which can result in
distortion of moving objects.

There is also an automatic setting (AUTO), in which the shutter speed is adjusted automatically according
to the overall light level.

Note: Faster shutter speeds should not be used when operating the camera under fluorescent lighting. The
intensity of the light varies at the AC line frequency (60Hz) and causes dark bands to appear across the
image.

8.3.1.4. Gain Control

Gain can be set to automatic (unchecked), in which case the camera will automatically adjust to variation
in illumination and subject matter or to manual (checked) in which the user controls the variation in
illumination and subject matter.

8.3.1.5. Gamma Correction

Gamma correction switches between 0.45 and 1.0 to accommodate various monitors.

8.3.1.11. Manual White Balance

When Manual mode is selected, Red and Blue levels can be adjusted from 0 to 255.

8.3.1.12. Edge Enhancement

Edge enhancement is used to make the edges of lines appear sharper and more distinct. It gives the
appearance of increased resolution, but in reality the resolution is determin ed purely by the number of
pixels, and is fixed.

8.3.1.13. Back Light Compensation (BLC Control)

Under normal lighting conditions, with the Electronic Iris control activated, the camera will automatically
adjust the image brightness so that all parts of the image are visible.

However when the background illumination is very bright, as when someone is standing in front of a
window for example, the shutter speed will automatically be reduced causing the foreground image to
appear darkened. With the image appearing in this way, faces may look almost in silhouette making it
difficult to see any detail.

In this situation, Back Light Compensation (BLC) can be used to increase the brightness of certain parts of
the image.

Back Light Compensation effectively limits the area of the screen in which the AGC operates, thus
ensuring that details within the area will not be lost. As a consequence, regions of the image outside of
the BLC area may become very bright and washed out.

To enable BLC simply click on the Enable Backlight Compensation Check box.
The size of the BLC window can vary in both size and shape. To change the BLC size, click on the Region

Width and/or the Region Height radial buttons and choose 1/8, ¼, ½, or Full.
To change the X or Y position, click on the arrows provided above and/or to the left of the 8 x 8 grid.

With Isochronous Transfer mode a fixed bandwidth (up to a maximum of 40% of the total available) is
assigned to the camera, ensuring a minimum transmission speed. In this transfer mode, there is no error
correction and any dropped data will not be re-transmitted. This mode is typically used for time sensitive

packets, which are retransmitted.

If multiple USB cameras are being operated simultaneously, it is possible that the data rate from the
camera will be reduced, resulting in a slower frame rate for the displayed image. In this situation the
isochronous display should be used.

If a single camera is being used, then the bulk transfer mode will likely provide the fastest display.

9. ALL MODELS - Using the TWAIN Interface

If the Twain interface (SFT-10011) is installed the camera can be used with any TWAIN Compliant
Application.

The TWAIN interface will attach itself to the first Videology camera it finds connected to the computer. For
best operation, run the TWAIN Interface on a system that has only one Videology camera installed.

Any application that supports a TWAIN Data Source as a capture device can access the camera. The
camera's image will appear as shown below:

10. Troubleshooting

10.1. Focus Issues

If the video appears out of focus, check that the lens is focused properly. Typically , a lens is pre-installed
and is pre-focused for an optimal head shot distance of 3.5 to 7 feet from the camera. If your subject is
out of that range then you will need to make a slight adjustment to the lens.

Unlock the locking screw on the lens and rotate the lens very slightly watching to see if the subject comes
in to focus. When you have the proper focus for the distance, lock the locking screw securely. It is possible
for a very tight locking twist to cause a slight focus shift, so take care to lock the screw gently and to
recheck that the image is still property focused.

10.2. Noisy or Grainy Video

Be certain that there is enough light in the room where the images are snapped and that your subject is
not located directly under a bright spotlight.

10.3. Poor Color Reproduction

Try the various white balance choices in the event that you have strange lighting conditions. The camera’s
default setting is set for standard fluorescent lighting. If the camera is setup outdoors, you may require a
more optimal white balance.

10.4. Dark faces

Subjects should not be placed in front of overly bright backgrounds, such as a window with sunlight
streaming through it. At the same time, be certain that the environment provides enough overall light.
Additionally, a solid light grey backdrop is preferred for headshots.

Doc # INS-07019 rev A Issue Date: 07/22/2011
Revision: A Preliminary Page 40 of 42

10.5. Reflections



Take care that the camera lens is at approximately the same height as the subject’s nose. There should
not be a high light point source in the ceiling angled in to the subjects face. This may cause glasses to
reflect or shadows to appear on the face. A hot white dispersed light aimed directly on to the face is
sometimes needed for an ideal image capture.

10.6. Video display shows a green or black color

For Win XP and Win 2000, update USB 2.0 Host driver to the latest driver from the Microsoft
For Win 98 SE and Win Me, an OS upgrade to either Win XP or Win 2000 with latest Microsoft
Host driver is necessary.
