Image Quality Testing Solutions


As a global leader in image quality testing, we leverage our expertise in image quality testing, equipment, and knowledge to help companies across industries worldwide improve their imaging devices.

Standard camera testing typically covers multiple image quality metrics such as resolution, texture detail retention, noise, dynamic range, color accuracy, distortion, shading non-uniformity, and chromatic aberration. Camera systems often require comprehensive multi-dimensional evaluation.

Through the efforts of our R&D department and the introduction of high-precision production equipment, Threenh has gained the capability to customize various types of test charts. We can produce all kinds of transmission-type test charts (e.g., film charts) and reflection-type test charts according to clients’ specified drawings. Commonly used camera testing charts such as resolution charts, color bar charts, distortion test charts, grayscale charts, and dynamic range test charts can all be customized, significantly reducing costs for high-tech enterprises globally.

FAQs About  Test Charts

Who are we? Threenh Technology: 22-Year Professional Color Measurement Solution Provider

Threenh Technology is a Chinese professional Measurement Instrument manufacturer with 22 years of industry experience, specializing in the field of color measurement and surface gloss detection. 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.


Ambient light may affect the test results and must therefore be kept to a low level for accurate haze meter results. 


Gloss is a broad term to describe the reflectivity of a surface. Whereas high gloss is a specific term that has the highest reflectance (usually more than 70 GU). High gloss finishes are shiny, mirror-like, and exhibit more surface blemishes than lower gloss finishes.


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.

In the study of chemical reactions, calorimetry deals with changes in heat (energy and enthalpy). Spectrophotometry is the measurement of the light absorbance or light transmittance to determine the concentration or color of a solution. The first one monitors the thermal processes, whereas the second one addresses the aspects of light and color.


The gloss meter is used to measure the gloss level: it is a device that directs the light at a fixed angle and reads the intensity of the reflected light. The angles, such as 60°, 20°, or 85°, are applied depending on the type of surface and the range of gloss.
