Test chart for flare measurement compliant with ISO18844! Introducing the selected test chart from ImageEngineering!
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.

basic information
【Features】 ■Compliant with ISO 18844 ■17 light traps (super black hole) ■Analysis using image analysis software iQ-Analyzer (Version 6.1 or later) * *TE281 can be analyzed using the flare module of the image analysis software iQ-Analyzer (Version 6.1 or later). (Currently, analysis with iQ-Analyzer-X is not supported.) The flare module of iQ-Analyzer can compare the white level and black level of test images to calculate the proportion of scattered light and indicate the amount of flare.
