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.
The Grab (v18.104.22.168_171218), hereafter referred to as "Grab" LabVIEW software is an example program designed to demonstrate the various functions and operation of the Vieworks pixel shift cameras such as the VN-25MX-M72AO 25MP pixel shift coaxpress mono 72fps camera connected to a Euresys Quad G3 coaxpress board in a Win 7 computer running LabVIEW Full version or higher. This software was developed using National Instruments LabVIEW 2015 and should run on LabVIEW 2015 or more recent
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.
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.
