Document Feedback NanEye / NanEye Stereo General Description 1 General Description NanEye is a miniature sized image sensor vision applications where size is a critical factor. The ability of the camera head to drive a signal through long cables makes this the ideal component for minimal diameter endoscopes. With a footprint of a just 1 mmx1 mm, it features a 249x250 resolution with a high sensitive 3-micron rolling shutter pixel, with large full well capacitance. The sensor has been specially designed for medical endoscopic applications where high SNR is mandatory. The sensor has a high...

Document Feedback Functional Description NanEye / NanEye Stereo Functional Description Sensor Architecture Figure 2 shows the image sensor architecture. The internal state machine generates the necessary signals for image acquisition. The image is stored in the pixels (rolling shutter) and is read out sequentially, row-by-row. On the pixel output, an analog gain is possible. The pixel values then passes to a column ADC cell, in which ADC conversion is performed. The digital signals are then read out over a LVDS channel. Pixel Array The pixel array consists of 249 x 250 square rolling...

Document Feedback NanEye / NanEye Stereo Functional Description 7.1.2 Analog Front End The analog front end consists of 2 major parts, a column amplifier block and a column ADC block. The column amplifier prepares the pixel signal for the column ADC. The column ADC converts the analog pixel value to a 10 bit value and can apply a gain. All gain and offset settings can be programmed using the I2C interface. The LVDS block converts the digital data coming from the column ADC into standard serial LVDS data running at around 30 Mbps. During transfer of the image data, the pixel values are...
