The EyeCAM camera

The EyeCam system : A compact embedded system for motion analysis

Real time picture compression
Integrated light, red and near-infrared to improve markers detection accuracy
FPGA component for embedded processing
Using with a common laptop thanks to embedded processing
Fast USB 2 streaming
Up to 6 EyeCams connected to a common laptop

Thanks to our specific algorithms, the EyeCam system can detect marker placed on the body and calculate their position with high accuracy.

As actual PCs almost always have at least 3 USB ports, we use USB connection to plug easily several EyeCam on the same laptop.

Technical features of the acquisition system

The EyeCam device uses a fast CMOS sensor. It allows to do acquisitions up to 250fps with a 640x480 picture size(VGA). The other characteristics of this sensor are summed up inside the following board :

Parameters	Values
Optical format	1/2 inch
Active Pixels	640 (H) x 480 (V)
Pixel size	9.9 µm x 9.9 µm
Shutter type	Electronic Snapshot
Maximum data rate	80 MPS/80 MHz
Frame rate	240fps (640x480)
ADC resolution	10-bit, on-chip
Responsivity	3200 V.m2/W.s
-	17 V/lux.a
Dynamic range	61 dB
Supply voltage	Analog. 2.5V-3.3V
-	Digital. 2.5V I/O:2.5V
Power comsuption	190 mWatt
Temperature Op	-40°C to 70°C
Color filter array	Mono RGB Bayer Pattern

Using this sensors at their maximum capcities, allows EyeNetics to propose efficient devices for concurrential prices.
