OECF test chart
Introducing the selected test chart from ImageEngineering!
Measuring the camera's characteristic curve is one of the important tests. The function obtained as a result is called the Optical-Electrical Conversion Function (OECF). 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.
