Subjective real scene test chart is based on personal subjective feelings, building a test scene, taking photos with a camera, and then subjectively judging the performance of the camera in all aspects through the photos.

The YE0670 real scene test chart elements include charcoal, feathers, sponge, fabric, yarn, hemp rope, etc., which can be used to analyze the performance of the lens in reproducing the texture of different materials. 24 color cards with rich colors, fruits, flowers, color ratios, and children's toys can be used to analyze the color performance of the lens. Resolution cards, newspapers, QR codes, labels on wine bottles, and more can be used to analyze the resolution capability of the lens.

FAQs About  Other Charts

The LAB color space defines colors in a three-dimensional model: Lightness (L), red–green axis (a), and blue–yellow axis (b). It's a globally recognized standard supported by most modern color measuring devices. CIELAB is a standardized, device-independent system designed to map all visible colors that the human eye can perceive.

The LAB color space uses three values to define any color, each representing a specific dimension:


L (Lightness): Ranges from 0 to 100. It measures the brightness of the color, where 0 is pure black and 100 is pure white.
A (Red-Green Axis): Ranges from approximately -128 to +127. Positive values represent red tones, while negative values represent green tones.
B (Yellow-Blue Axis): Ranges from approximately -128 to +127. Positive values represent yellow tones, while negative values represent blue tones.


The "accuracy" of a colorimeter refers to how closely its measurement results align with the true values, primarily influenced by systematic errors and random errors, how closely its measured color data (e.g., Lab values, density) aligns with the true color properties of a sample or certified standard. Specifically, it includes key indicators such as color coordinate accuracy, luminance accuracy, and data repeatability.

It reflects the instrument’s ability to minimize deviations caused by component variations, environmental factors, or calibration drift—ensuring results reliably represent the actual color, which is critical for quality control and brand consistency in industries like printing, food, textiles, paint and coatings.

Haze Meters are utilized in production and quality assurance in the plastics, glass, films, and coatings industries, where transparency and example are essential.


Testing metamerism helps to identify color matches that look the same but are different in different lighting. This helps in ensuring that materials are of the same quality in all light settings.


Keep light booths clean, maintain the light source lamps, readjust the calibrated light source, and ensure that dust and fingerprints do not settle on the viewing area.


Take L*a*b* readings of two samples using a colorimeter or spectrophotometer and calculate color difference using the 3 formula (Delta E). The difference in 0 is the reported Delta-E, which shows how visible the change is, whereas the thresholds define the acceptability as per the application requirements.
