Image Sensor

ET2-GS-FC

ETReadOUT Board

The ETReadOUT board is included with the sensor and serves as an extension module that integrates the ET-1080 and ET2-GSA sensors. It includes the necessary conversion and control electronics for facilitating communication between the sensors and the FPGA (Field-Programmable Gate Array). This board controls and converts the two differential outputs into digital signals, which are then sent to the ZCU104 board via the onboard FMC connector.

The board operates at 100 MHz, allowing a maximum achievable frame rate of 12 frames per second (fps) in full-frame mode. To achieve a higher frame rate, sub-windowing is required.

Why Eye2Drive Sensors?

Adaptive HDR

With the EYE2DRIVE imaging sensor, High Dynamic Range (HDR) can be adjusted from low to very high, providing an optimal balance of contrast.

Tuned Sensitivity

If lighting is low in the current context, EYE2DRIVE’s imaging sensor can increase sensitivity in real time, providing the critical, reliable information needed.

No Artefacts

Eliminate flickering and ghosting! Everything is displayed natively in a single image, resulting in a zero data payload and no artifacts or ghosting when moving objects are present.

Low Power

The EYE2DRIVE E2D-1080 and ET2-GS image sensors are designed for low-power applications, such as autonomous car navigation systems, and are built around a standard linear pixel.

EYE2DRIVE hardware technology for adaptive HDR is protected by a patent family that the company owns:

United States Patent Office

Patent US9918026

Photodetector device for electro-optical sensors with variable light dynamics

The US Patent Office has officially registered patent US9918026, which is also listed under WO2013046003, EP2761657, and ITUD20110149. This patent was filed in 2012 and describes a mechanism for photodetection in electro-optical sensors. It features a pixel that converts light into a voltage output. The mechanism includes a charge dissipation system and a specialized circuit that regulates the reset voltage. This regulation circuit is designed to alternately connect the reset terminal and the externally programmable reference terminal. Additionally, it can be used by multiple pixels simultaneously, enhancing the device’s functionality and flexibility in capturing light information.

Patent US11184568

Pixel charge control circuit in digital devices for image acquisition

Patent US2014204189, also registered as WO2018229645, EP3639512, and IT201700066147, has been officially registered with the United States Patent Office. It was filed in 2012 and describes a photodetector device for electro-optical sensors. The device features a pixel that converts light into a voltage signal. In addition, it includes a mechanism for controlling charge dissipation and a circuit that adjusts the reset voltage. This circuit can switch connections between the reset terminal and an external programmable reference terminal, which can be shared among multiple pixels to enhance the device’s efficiency and adaptability in photo-detection

European Patent Office

EP4154517.A1

Multi-dynamic vision sensor

The EYE2DRIVE patent, EP4154517, also registered as WO2021234566, has been officially registered with the European Patent Office. This patent describes an electro-optical image acquisition device that incorporates multiple light-sensing sub-blocks. It employs pixel discharge control circuitry to generate a range of reset curves, which are dynamically selected for each photosensitive element. This method allows for the capture of “multi-dynamic” images with varying light conditions, thereby enhancing image quality and enabling advanced information extraction. Additionally, the patent details a process that applies reset curves line by line, ensuring effective operation under any lighting circumstances.
