Our Technologies

CeleX Sensor

We develop an imager architecture that allows pixel-parallel image processing at the focal plane and event-driven readout. Each pixel in our sensor can individually monitor the slope of change in light intensity and report an event if a threshold is reached. Row and column arbitration circuits process the pixel events and make sure only one is granted to access the output port at a time in a fairly ordered manner when they receive multiple requests simultaneously. The response time to the pixel event is at nanosecond scale. As such, the sensor can be tuned to capture motion objects with speed faster than a certain threshold. The speed of the sensor is not limited by any traditional concept such as exposure time, frame rate, etc. It can detect fast motion which is traditionally captured by expensive, high speed cameras running at tens of thousands frames per second and at the same time produces 1000x less of data.

CeleX Chipset

We offer integrated sensory platforms that incorporate various components and technologies, including a processing chipset and an image sensor. CeleX Chipset is a hardware implemented video analytics system, which perceives stream of pixels from the sensor and conveys value-added signal processing. The resulting system will be a software-hardware co-processing platform, enabling high speed implementation of video analytic tasks such as optical flow and convolution. The platform features standard interface to existing vision systems. It overcomes the over demanding computing power requirement of the existing vision based systems which are difficult to be realized in mobile computing platforms.

We develop world-leading Smart Camera. Our product performs real-time interpretations and immediate analysis of high-speed motions

Features

CeleX is a new family of high speed dynamic vision sensors (DVS) featuring continuous motion tracking in both space and time domain.

thumb_up

Efficiency

The sensor is built on an architecture that allows pixel-parallel image processing at the focal plane and straightforward event-driven readout.

import_export

Low Data Rate

Only active pixels matter. The sensor can capture ultra-fast motion and reduce the data amount by 1,000 times.

loop

Continuous

Each and every pixel along the motion's trajectory will be captured, stamped with accurate time information at nanosecond resolution.

flash_on

Fast Reaction

The speed of the sensor is not limited by any traditional concept such as exposure time, frame rate, etc. Actually, CeleX has no exposure time.

High Dynamic Range

CeleX has a high dynamic range of >120 dB. It also supports a wide lighting range from moonlight to daylight.

Compatibility

CeleX is compatible to existing image sensors, as it can easily produce full-frame pictures on demand.

Comparison With Traditional Sensors

CeleX Traditional Sensors
Data Rate MP/s spot of interests with no redundancy GP/s of data with redundancy
Response Time nanoseconds > milliseconds
Frame No frames, continuous tracking in both time and spatial domain Discrete, thus fast motion tracking requires more frames

  • today Ultrafast camera for self-driving vehicles and drones

    Unlike typical optical cameras, which can be blinded by bright light and unable to make out details in the dark, NTU's new smart camera can record the slightest movements and objects in real time. The new camera records the changes in light intensity between scenes at nanosecond intervals, much faster than conventional video, and it stores the images in a data format that is many times smaller as well..
