Product Description

Digital High Dynamic Range Camera Lens Test Chart OECF 36 Chart SineImage YE0269

SineImage YE0269 Digital high dynamic range cameras OECF 36 chart
 
Model YE0269
Type Transparent
Size 280 x 157.5mm
Ratio 16:9
Material Film
 
OECF 36 Chart (following ISO 14524/15739 and upcoming IEC 62676-5)
 
YE0269 version 2 (V2) uses the same data measurements as the original version, but has a different hardware design. The first version of the YE0269 uses two plates of glass built around the chart film. On occasion we encountered a few problems with stray light and reflections from the glass. Version 2 replaces the glass with a metal frame, which greatly reduces the chance of stray light and reflections.
 
When working with high dynamic range cameras, it is normal to use OECF charts with patch densities according to ISO 14524. However, many of these charts have large gaps between the high-density patches because they are calculated using the cube root formula.
 
Our 36 patch OECF YE0269B V2 chart presents a solution for this problem. While these charts still closely follow IS0 14524, it also implements additional steps to address the higher density levels. High dynamic ranges up to 1.000.000:1 / 120 dB are attainable using these charts. In addition, they also benefit from having a stable production process and being strongly neutral.
 
Principle
Transparent gray scale test chart to determine the OECF, noise, SNR and dynamic range especially of digital high dynamic range cameras.
 
Values that can be gathered from analysis
 
• OECF / gamma curve
• dynamic range
• noise
• temporal noise
• visual noise
• SNR
• ISO speed of the camera
 
 
Technical information
These transparent test charts are available in size D280
The aspect ratio of the test pattern is 16:9 with integrated markers for 4:3 and 3:2 formats
36 patches with densities from 0.03 up to more than 6 (for 1.000.000:1 / 120dB and higher)
The standard version of YE0269 V2 uses a screening to form the gray levels
The three variants available are:
 
YE0269A V2
Gray patches according to ISO 14524.
 
YE0269B V2
Better differentiation of the dark patches. The steps are based on the supporting points of the TE264 (20 patch chart) with a spreading of the steps in between.
 
YE0269C V2*
According to the upcoming standard IEC 62676-5: Video surveillance systems for use in security applications – Part 5: Data specifications and image quality performance for camera devices, this chart is adapted to the postulated requirements.
 
*For YE0269C V2 we recommend using with a strong illumination device, such as T25900.
