e2v Introduces New CMOS Image Sensor With Embedded Features For Industrial Imaging
Featuring dual 'true global' and 'rolling' shutter modes, the EV76C560 is the first in a family of high-sensitivity CMOS imagers aimed specifically at industrial machine vision, barcode scanning, surveillance and other demanding imaging applications.
This new device is ideal for applications requiring superior low-light performance or where very short integration times are necessary (for example in high speed video streaming applications), or where illumination power must be minimised. The 1280 x 1024 imager comprises 5.3ยต pixels with a unique architecture that assures very high efficiency global shuttering (3000:1) while maintaining excellent quantum efficiency (QE). It outputs full resolution images in a 10bit parallel format at 60 frames per second. Furthermore, with the ability to switch 'on the fly' to a true 4T electronic rolling shutter mode, users can optimise the signal to noise ratio (SNR) performance against available lighting and scene motion content capture requirements.
Novel pixel integration/readout modes and embedded image pre-processing deliver superior performance parameters including a bi-frame wide dynamic range (>100dB) free of the artefacts normally encountered with non-linear WDR techniques, to enable imaging of day-lit scenes with excellent colour and contrast ratio in both shaded and bright regions of the image.
Image analysis algorithms and multi-tasking video applications perform like never before due to unique features such as multiple regions of interest (i.e. 4 separate windows) that provide users with unprecedented control. Each window frame output carries its own image histogram encoded in the image data stream footer. In addition to the size and position of each window, the EV76C560 offers the user control of the integration time, gain, sub-sampling, repetition rate and other uniquely configured parameters; rather like having up to 4 different sensors under the same lens.
Gareth Powell, Marketing Manager of e2v's Industrial Imaging Group said, "We have received great feedback from tests on initial sample devices by our partners and customers; that the EV76C560 is the only device of its kind serving professional imaging markets which has been specifically designed with the performance and features demanded by these markets and to the right price."
