Software provides control over defective pixel correction.

Press Release Summary:



DPC Processor utility gives users ability to create pixel-correction tables for company's CCD cameras. Defective Pixel Map (DPM) file stored in camera's internal non-volatile memory will correct values put out for up to 128 defective pixels. System uses correction algorithm based on coefficients in DPM file to calculate digital value camera would have put out for each defective pixel. Main dialog window provides controls required to set thresholds.

Imperx Utility Gives Users Control Over Defective Pixel Correction



9 May 2006 (Boca Raton, Fla.) -- A new DPC Processor utility, available from high-performance machine-vision camera manufacturer Imperx, gives users control over the process for correcting defective pixels in their camera's CCD. All Lynx-series Camera-Link and GigE cameras have on-board defective-pixel correction capability using pixel correction tables developed at the factory from final-test measurements. Some power users, however, want to create their own pixel-correction tables because their application requires modified pixel-selection criteria.

Defective pixels are classified as "dark" (low sensitivity), "light" (high sensitivity) or "hot" (sensitivity increases with exposure time) relative to the average responsiveness of all pixels on the CCD. Such variations are usually at least annoying, and can be devastating, depending on their application's requirements.

Imperx camera software allows the use of a Defective Pixel Map (DPM) file stored in the camera's internal non-volatile memory (NVM) to correct the values put out for up to 128 defective pixels. The system uses a correction algorithm based on coefficients in the DPM file to calculate the digital value the camera would have put out for each defective pixel, had that pixel worked properly.

While all Imperx Lynx cameras are capable of making these defective-pixel corrections, the factory-developed DPM files use criteria (such as thresholds for classifying pixels as "dark") that work well for most applications, but may not be ideal for a given application. Imperx' DPC Processor utility steps users through the process of building their own DPM files. All the user has to do is set the camera up to view a blank screen lit evenly with an adjustable illumination level. The DPC Processor main dialog window provides all of the controls required to set thresholds and control the test. Additional dialog windows allow the user to upload the new DPM File to the camera's NVM.

About Imperx
Imperx, Inc. designs, develops and manufactures advanced, state-of-the-art imaging products used in the machine vision, medical, defense, surveillance and astronomy markets - wherever there is a need to capture high-resolution digital color or black/white images for both still and full-rate motion processing.

Imperx' product portfolio is focused in four core areas: cameras, frame grabbers, adapters and repeaters. The LYNX mega-pixel camera line features rich, high resolution, high speed, color and monochrome image-capture devices, and offers unprecedented performance for today's demanding machine vision and surveillance applications. The VCE series of analog frame grabbers have achieved number-one market share. Framelink(TM) digital frame grabbers for Camera Link® cameras are the only products of their kind on the market! The Adapt-A-Link(TM) series of adapters allows customers to leverage their investment in existing cameras or frame grabbers with dissimilar interfaces by performing the necessary adaptation. The Imperx series of Adapt-A-Link(TM) repeaters overcomes distance limits imposed by the Camera Link® and LVDS standards, providing virtually unlimited physical reach for distributed image-sensing systems.
