The TE42-LL is a multipurpose test chart used for measuring digital cameras' low-light performance and other image quality factors based on ISO 19093.
ISO 19093 describes a protocol to measure the low light performance of a digital camera (including mobile phones). It includes the proper test setup and illumination with the spectrally tunable iQ-Flatlights.
The TE42-LL chart is based on the original TE42 multipurpose chart and is the chart that is used in the standard itself. The main difference between the two charts is the layout at the center. The low-light version has all of the important structures, such as the low-light Siemens stars and slanted edges, at the center of the layout to avoid fall off at the corners and to ensure all of the targets are equal distance to each other.
Using the TE42-LL, you can analyze all of the critical low-light and image quality factors in one image. ISO 19093 recommends using this chart for the best measurement results.
There are various sampling rates for the chart. Our sales team will be happy to provide you with further information on this.
The TE42-LL is compatible with the iQ-Analyzer-X image evaluation software.
