Flare is unwanted light in an image caused by light reflecting off various surfaces within the lens and camera. Flare generates a diffuse veil over the image field, significantly degrading image quality and leading to a decrease in contrast. The TE281 is a flare measurement chart designed in accordance with the ISO 18844 standard for measuring flare (Image Flare) in digital cameras. The TE281 features a total of 17 holes arranged diagonally across the chart, and light traps (super black holes) are attached to each hole from the back of the chart for use. The super black hole acts like a blackout curtain to emphasize black, absorbing a high percentage of light to produce the lowest possible black level. The ideal light source for the TE281 is a standard lighting system for reflective charts, such as Studio Lights. *Flare measurement with the TE281 only targets flare caused by light within the field of view of the test camera module. **The TE281 standard is a reflective chart of size A1066, but custom charts in a transmissive version can also be provided upon request.

For the various applications of cameras in industrial image processing, the necessary conditions for cameras change depending on the application. Image processing, which demonstrates a wide range of true capabilities, provides data to verify quality, identify parts, read codes, and optimize manufacturing processes, while also controlling machines. Recommended products for machine vision evaluation allow for testing of key quality criteria such as dynamic range, resolution, sensitivity, noise, and frame rate, including optical systems and sensors. In machine vision, lighting is usually controllable. Therefore, a normal contrast of 10,000:1 is sufficient for the OECF chart. However, since tone levels are used for automatic detection and evaluation of various elements in images, it is helpful to measure the OECF in as much detail as possible. For this reason, the iQ-LED equipped lighting device (integrating sphere) LE7 for transmission charts and the 36 gray patch chart TE269B are recommended. For color, resolution, distortion, and shading, standard charts (TE253 9x, TE230, TE251, TE255) can be analyzed using the image analysis software iQ-Analyzer-X.

The continuous development of camera technology is expanding the requirements for image technology in the security field. New features such as motion and facial recognition have been added as standard. The amount of data transferred continues to increase, and consequently, the quality of image materials is required to be high. This enables software-based evaluation systems. Security cameras must operate under various conditions, utilizing LED lights and other means, from direct sunlight to extremely low brightness levels. Since they must function under high contrast levels in direct sunlight, cameras need to have a high dynamic range, and it is optimal to use TE269C (compliant with IEC62676-5 video surveillance camera standards) in front of high-intensity flicker lighting devices like LG3.

When testing digital cameras, an important metric is resolution. The resolution that complies with ISO standard 12233 (digital still cameras) and ISO standard 16067 (scanners) refers to the ability of an image capture device to reproduce the details of the scene being photographed. What is important here is that the number of pixels is not the same as resolution. The number of pixels is necessary to achieve the required resolution, but not only optical components such as lenses and aliasing removal filters, but also image processing significantly affects the camera's resolution. Additionally, the smaller the number of pixels, the greater the impact of optical components on the resulting resolution. We offer the "TE253" sine wave Siemens star chart, which allows resolution analysis at nine positions within the image, as well as the "TE268" in our lineup.

OECF measurements can be conducted based on ISO standards 14524 and 15739, using one of the well-known charts: "TE264," "TE269," or "TE270." These standard charts use a halftone process to create gray levels on lithographic film. For waveform monitors, "TE223" with a horizontal grayscale is recommended. Cameras without manual exposure control can be tested using "TE270X." 【Main OECF Charts】 ■TE269: OECF Chart (Compliant with ISO standard 15739) ■TE264: OECF20 Chart (Compliant with ISO standards 14524 / 15739) ■TE223: HDTV Logarithmic Grayscale Test Chart ■TE270X: OECF Chart (Compliant with ISO standards 14524 / 15739) *For more details, please refer to the PDF materials or feel free to contact us.

The color reproduction test chart (color chart) is used to check the quality of a camera's color correction (reproducibility). On the other hand, this can also be seen as a subjective analysis of preferred colors and a measurement of color reproduction. In the latter case, the image is converted to the CIELAB space, and the color values are compared with the measured colors of the original target. A good method is to use the camSPECS device to measure spectral sensitivity. A commonly used chart for cameras in this field is the X-Rite ColorChecker, but ImageEngineering sells it as "TE188," while the IT8 for scanners is sold as "TE258." "TE226" is a transparent extended version of the ColorChecker. For cameras, the extended version becomes the X-Rite ColorChecker SG, which is sold as "TE230" and has become the standard test chart.
