Advances in CCD and CMOS imaging sensor technology, coupled with the ability to leverage imaging technology needed to manufacture high-volume consumer products such as cell phones and flat panel displays (TVs & Computer Monitors), are driving development of ultra-high-resolution (UHR) imaging cameras. These cameras offer the performance that today’s vision applications demand such as a larger field of view (FOV), greater accuracy, and faster throughput.
Pixel shift technology is used to significantly extend an industrial camera’s resolution beyond that of its native resolution by nano-shifting the sensor a fraction of a pixel or what is commonly called subpixel rendering. A full resolution image is captured and saved for each shift.
What is Pixel Shifting?
As industrial imaging applications such as automated optical inspection (AOI) and document scanning demand greater precision, higher throughput, and lower build costs, developers must rely upon ultra high-resolution cameras to reduce the complexity and cost of deploying these systems.
Machine Vision vs. High Speed Video
When you read that a camera is high speed do you every question why? What qualifies a camera to be high speed? This is a fair question since so many cameras with a vast difference in performance all are described as “high speed”.
