The optimal multipurpose test chart for low light characteristic measurement! Introducing the carefully selected test chart from ImageEngineering!
The "TE42-LL" is a test chart modified from ImageEngineering's multipurpose test chart "TE42" for low light measurement, compliant with the ISO 19093 standard for measuring digital cameras' low light performance. Like the "TE42," it can be analyzed using the image analysis software "iQ-Analyzer" and "iQ-Analyzer-X." The main difference from the "TE42" is the central layout, where the "TE42-LL" positions all critical targets, such as low light Siemens stars and inclined edges, in the center to avoid performance degradation at the corners, ensuring that all targets are equidistant from each other. ISO 19093 - low light performance Given the importance of developing an international standard that addresses optimal analysis methods for digital cameras' low light performance, ISO 19093 is a standard compiled by the ISO/TC42 working group, detailing protocols for measuring the low light performance of digital cameras, including mobile phones.

basic information
ISO 19093 defines the test setup, lighting equipment, and test charts necessary for properly analyzing low-light characteristics, with 'TE42-LL' being cited as the optimal test chart. Additionally, the 'iQ-Flatlight', a spectrum-adjustable diffusion light panel equipped with 10 iQ-LED V2 light sources, is recommended as the optimal light source for low-light characteristic measurements using 'TE42-LL'.
