The YE0175 is designed for measurement of the disturbance caused by the video level in black areas to the right of or below the areas. Horizontal white lines are positioned on a black background.

Definition of streaking measurements

Measurement of the disturbance caused by the video level in black areas to the right of or below the areas.The disturbance is characterized by measuring the duration of the delay before the video level corresponding to the normal video level of the black is restored.

Measuring equipment

Video level meter; B/W monitor, oscilloscope, low-pass filter: 500 KHz

Measurement conditions

The chart illumination must be adjusted so that the white bars give a signal of 100% with average iris setting.

Gain: 0dB

FAQs About  Other Charts

A visual colorimeter is a type of colorimeter that uses the human eye to compare the color depth of a sample with that of a standard solution for semi-quantitative or quantitative analysis of substances. This method is commonly used for quick, rough evaluations in industries such as petroleum, transparent liquids, varnishes, chemicals and printing, as well as for visual color grading in quality control. Its working principle is to compare the sample with a standard and provide visual color measurement results, rather than relying on electronic sensors.

Visual Colorimeters vs. Photoelectric Colorimeters

Visual colorimeters rely on human eye observation, whereas photoelectric colorimeters use sensors to deliver higher precision, complete the measurement automatically through electronic circuits, less subjective color measurement and faster results. They are generally more suitable for rapid, on-line or portable color difference measurement.

Working principle of a photoelectric colorimeter

A light source emits light at specific wavelengths, which interacts with the object surface through reflection and transmission. The light is reflected or absorbed by the sample, and the reflected light or remaining transmitted light is received by a photoelectric sensor (photocell or photodiode). The instrument converts the light intensity signal into an electrical signal, thereby measuring the LAB color values of the sample.

Many people might answer "with the human eye", but this is actually not comprehensive. The human eye cannot accurately distinguish the colors of similar objects. Furthermore, everyone's perception of color varies. Therefore, people have developed color measurement tools based on the CIE color system. 

Currently, there are two main types of commonly used colorimeters, as follows: 

Colorimeter - It is an ideal choice for quality control (QC) on production lines, used to detect color differences. 

Spectrophotometer - It is suitable for the development of color characteristics and color analysis in laboratories.

Pick a haze meter that correlates with your materials, precision needs, and applicable testing protocols. For lab-level precision, a bench-top version is advisable; for a rapid field check, a portable haze meter is appropriate. International standards must be met at all times.


Inaccurate color rendering, mismatched results, and noncompliance with ISO 3664 or ASTM D1729 can occur when there are deviations.

D65, TL84, A light, CWF, and UV are the most common standardized sources used for precise color matching.

L*a*b* is an L*a*b* color space. The L* is a measure of lightness (as 0 = black, 100 = white), a* indicates the green to red axis, and b* indicates the blue to yellow axis. It is also common in color measurement in terms of precision and reliability.
