  1. Security camera performance testing

    the most important KPIs for security video camera systems, including resolution, minimum illumination/low-light, dynamic range, infrared illumination, geometric distortion, veiling flare, and maximum frame rate. Other factors contributing to the overall...

  2. Units and conversions for dynamic range and noise values

    The Dynamic Range is the maximum contrast a camera is able to reproduce from the point the camera reaches it’s maximum output level (saturation) down to the point where the signal is just as high as the noise level so that noise and signal cannot be...

  3. Dynamic range - focal plane vs. scene based

    The dynamic range (DR) describes the maximum contrast ratio, which can be captured by a digital camera without highlight clipping and a signal in the dark patches which can be divided from noise. The dynamic range is a primary characteristic value of...

  4. Image Quality News - August 2021

    solution for analyzing your camera system's timing and autofocus performance. Learn more about iQ-Near Focus LE7-E A dynamic range of up to 1:100.000 for accurate low-light testing The LE7 is an iQ-LED-powered uniform lightbox for transparent test...

  5. Measuring Scanner Dynamic Range

    scanners to provide digital image files is rapidly growing. Currently there is no standardized method to determine the dynamic range of scanners. Therefore the data reported in technical specifications can be determined using different methods. An ISO...

  6. iQ lab - Camera Test

    mainly because the higher the ISO speed, the more noise found in the image. Higher noise potentially leads to a lower dynamic range. The predefined lens for image quality testing is always set to aperture 5.6. For each of these settings following...

  7. Contrast Detection Probability (CDP)

    to describe a camera's performance when reproducing the contrast of a scene. However, for a setting with extremely high dynamic range, such as those often encountered by ADAS (e.g., a scene with flickering light), the SNR value is not the best indicator...

  8. iQ lab - Mobile Test

    used by Vodafone to generate the VCX-score. The test procedure “iQ lab - Mobile Test” covers measurements of resolution, dynamic range, visual noise, distortion, sharpening, texture loss, color reproduction and shading under different light conditions...

  9. LG3

    technology, the LG3 creates new possibilities in image laboratories by considerably expanding the test areas for dynamic range measurements. The LG3 is capable of illuminating a high contrast test target with over 150000 lx (for the LG3 to make an exact...

  10. Solutions for Testing Flicker

    box on the market with flicker capabilities. Based on iQ-LED technology, the LG3 greatly expands the test areas for dynamic range measurements with the ability to illuminate a high contrast test target with over 150,000 lx. It is used with transparent...

  11. Multipurpose test charts

    includes evaluating the camera's performance for various image quality factors such as resolution, texture loss, noise, dynamic range, color accuracy, distortion, shading, chromatic aberration, etc. A camera system will usually need to be evaluated for...

  12. LE7

    380 – 1050 nm. The control software and API do not change. LE7-E The LE7-E version gives you the possibility to create a dynamic range of up to 1:100.000. Such a wide dynamic range greatly expands the testing possibilities especially when testing in low...

  13. A potential way "auto exposure" can work in digital cameras

    contrast range it was able to reproduce. That range was typically limited to a 6 to 8 stop contrast variation. For high dynamic range scenes the photographer had to choose by varying the exposure which part of the scene he wanted to be reproduced and...

  14. An overview of camera flickering light response

    lightbox on the market with flicker capabilities. Based on iQ-LED technology, the LG3 greatly expands the test areas for dynamic range measurements with the ability to illuminate a high contrast test target with over 150,000 lx. It is used with...

  15. TE240

    ISO 21550 Scanner Dynamic Range Chart The TE240 is designed to check the 35 mm-scanner dynamic range. It has 24 graypatches with a density range of 4.0 or 6.0. The reflective version consists of a 2.4 density range. The TE240 is supported by the...

  16. Using the dead leaves pattern for more than spatial frequency response measurements

    In this paper, we present results from experiments that use the pattern and different analysis approaches to measure the dynamic range of a camera system as well as to describe the dependency of the SFR on object contrast and light intensity. The...
