PAPILLON: UP-TO-DATE BIOMETRIC SOLUTIONS
from Russia

The reason for using the PAPILLON TVC-9.1 USB camera is its ample capabilities including macro- and microphotography, as well as advanced software controls for the shooting process, e.g. adjusting the exposure, brightness, contrast, color, etc.

The RASTR software allows you to change the exposure over a wide range through accumulating signal on the camera image sensor. In comparison with standard video cameras, this feature makes it possible to enhance the signal-to-noise ratio or to reduce the lighting requirements.

The camera has a color sensor embedded and a programmable mode of black-and-white emulation embodied. The camera is simply attached to the USB port of the computer and it requires neither special video board nor individual power source.

For taking photos, a PAPILLON camera-and-object holder is used. The camera ensures the imaging in a wide rage of linear dimensions, including the shooting of close-ups of small objects by means of extension rings that maximize its focal distance up to 30 mm (when using all the 3 extension rings), providing thereby the image capture with ten times magnification.

Capturing microimages is available through a microscope attached to the camera via special connector and equipped with a photomicrographic unit.

Color shooting is also available through an embedded infrared-cut filter that cuts the infrared component of light. This method of image capture enables the color images of higher quality than those captured in standard environment.

The PAPILLON TVC-9.1 USB camera is capable of taking pictures in infrared light, i.e. with infrared backlight or in conditions of natural or artificial light sufficiently intensive.

When using the PAPILLON TVC-9.1 USB, the following image parameters can be adjusted through the application window:

• image scale in the preview window
• image size to be recorded (2048 х 1536 or 1024 х 768 pixels)
• dynamic range of the image (8 or 10 bits) 
• chromatic level (color or grayscale image)
• exposure (program auto-exposure or manual exposure control)
• brightness and color balance

To shoot moving objects, the mode of recording a number of frames into the accumulation buffer is used. Then a needed frame is selected for further operation.

Live video of the object on the computer screen helps the user to achieve a better quality of the image by applying various adjusting tools.
