Image sensor addresses latest surveillance applications

ON Semiconductor is extending capabilities for critical high resolution industrial imaging with the introduction of a new 43 MegaPixel (MP) resolution, Charge-Coupled Device (CCD) image sensor in the convenient 35mm optical format. The KAI-43140 is suitable for use in applications where both very high resolution image capture and image uniformity is required, such as end of line inspection of High Definition (HD) and Ultra-High-Definition (UHD) flat panel displays and aerial photography.

The KAI-43140 utilises a new 4.5µm Interline Transfer CCD (ITCCD) pixel that increases resolution by 50% compared to the prior 5.5µm design while preserving critical imaging performance. Featuring a true electric 'global' shutter, the device supports full resolution frame rates up to 4fps through the use of flexible 1, 2, or 4 output readout architecture.

The KAI-43140 shares the same package and pin definitions as the popular 29MP KAI-29050 and KAI-29052 image sensors, allowing it to be incorporated into existing camera designs with only minor electrical changes - speeding time-to-market for adoption of the new device while retaining continuity with existing camera and lens installations.

The KAI-43140 provides very high resolution with high quality, highly uniform image capture across a wide range of exposure times, a combination that is critical for applications such as flat panel inspection, where the resolution demands of the inspection system track with the ever-increasing resolutions of displays themselves. The new device also enables surveillance and aerial photography systems to capture more detailed imagery, or capture at a higher altitude to speed acquisition time and lower costs. 

“Many industrial imaging applications demand the image uniformity currently only available from CCD technology, while needing the resolution increases that require continued pixel development,” said Herb Erhardt, Vice President and General Manager, Industrial Solutions Division, Image Sensor Group at ON Semiconductor.

“With the KAI-43140, camera manufacturers and end customers can continue to push the boundaries of high resolution image capture without sacrificing the image quality their applications require.”
