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.

Integrating research and development, design, production, marketing, and sales, the company takes technological innovation as its core and is committed to providing global customers with high-precision and intelligent testing instruments as well as professional solutions.


The measurement of color varies according to context in several units. Such common units are L*a*b* (CIELAB), RGB (Red-Green-Blue), and color difference (Delta E). In light absorption, there are no units assigned to absorbance. But the quantitative analysis of absorbance obeys Beer's Law in colorimetry.

Color is a qualitative and quantitative measure. Qualitatively, it can be characterized by the hue, the saturation, and the brightness. It is quantified in terms of color spaces, such as L*a*b* or RGB, in terms of numerical values based on devices such as colorimeters or spectrophotometers.

a. If this phenomenon occurred, it means the battery power is not enough. You need to charge the battery.

b. When charge the battery, please insert the battery to the instrument, and plug in the adapter to charge the battery. After 5 minutes, the instrument can be turned on.

c. If the instrument still cannot be turned on after charging 5 minutes, you can pull out the adapter and re-plug in to check it. Or repeat this operation.

d. If the instrument still cannot be turned on after charging 5 minutes, you can turn off the colorimeter and turn on it again to check it. Or repeat this operation.

e. If you have tried all the methods above but the colorimeter still cannot be turned on, please change the battery.

A Spectrophotometer color measuring device objectively determines the color of a surface. It is used wherever accurate color matching, reproducibility or deviation control is needed – for example in quality assurance, product development or incoming goods inspection.

Spectrophotometer color measuring devices primarily perform three key tasks:

Capture color information: They detect light reflected, transmitted, or emitted by a sample using optical sensors.
Quantify color data: They convert the captured optical signals into standardized numerical values, such as RGB, CMYK, or CIELAB coordinates.
Compare color consistency: They compare the measured color data of a sample against a target or standard to assess color accuracy and uniformity.


The gloss of the paint is defined by the measurement of light reflection at the surface of the paint with the help of a gloss meter. The angle and quantity of light reflected determine the level of gloss, with smoother and reflective surfaces having a higher level of gloss.
