3 1 Overview NanEye is a tiny camera module which consists of a CMOS image sensor with a footprint size of 1mm x 1mm and, optionally, an adapted miniature optics. The device is mounted on a flat ribbon cable measuring up to 2m in length. Other cable lengths, up to 3m are possible upon request. The Evaluation set consists of the NanEye base station which receives the NanEye sensors LVDS bit serial data stream and translates it to a USBII protocol that will interface over a standard USBII connection to a PC. The supplied viewer software controls the NanEye camera, and displays the video images. Figure 1: NanEye evaluation set overview block diagram Page: 3/15

4 2 NanoUSB2 Evaluation Board NanoUSB2 base station is a miniaturized FPGA USB2.2 control board that is able to deserialize and communicate with AWAIBA NanEye sensor, and transfer the data via USB2 to a host PC. The base station is powered over the USB 5V supply and creates a regulated power supply for the sensor. Finally, the base station handles the upstream configuration data for the configuration of the sensor registers, such as the exposure time, offset and gain.

11 4 Evaluation Software The Evaluation system comes with the USB evaluation unit that receives data from the FPGAModule with one Nan Eye and the windows software to run the camera on a PC in real-time. Image display and storage is provided. It has the following features: Possibility to adjust white balance automatically Possibility to save directly to compressed.avi streams of either the processed or the raw data Possibility to save snapshots in PNG and in PGM (saving the 10 bit raw data) Possibility to acquire black and white gain masks Dynamic Gain and Offset switching Load in runtime a new configuration and change the sensor/board to receive images Possibility to control the LED intensity This software also contains some Image processing algorithms: Colour Reconstruction Gamma Correction (only for colour version) Pixel linear correction Adjust colour saturation Adjust brightness An API interface to the data stream is available for easy integration in existing display systems and evaluation of image processing algorithms.
