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

Gloss levels are usually of five types, namely, matte, eggshell, satin, semi-gloss, and high gloss. These categories are of rising levels of reflectivity of the surface and are utilized to characterize the completion of paints, coatings, and other substances.


Of course! Many portable, battery operated, and lightweight coating thickness gauges are available for on-site and field inspections. They provide quick and accurate results and portable gauges are ideal for construction, automotive, and industrial environments.


Measurement Accuracy (dE/ΔE): The smaller the value, the higher the match between the color measured by the colorimeter instrument and human visual perception. Generally, dE < 1.0 is regarded as the industrial passing line, while dE < 0.5 falls into the high-precision level. 

Measurement Structure: D/8 (integrating sphere structure) is the universal standard, which includes two modes: SCI (Specular Component Included, with specular reflection light) and SCE (Specular Component Excluded, excluding specular reflection light). 45/0 (ring illumination) simulates the human eye's viewing angle and is more suitable for judging reflective materials. 

Repeatability: It refers to the difference in color results when measuring the same point multiple times. The equipment can achieve ΔE < 0.08, ensuring highly reliable measurement results. 

Illumination Source and Viewing Angle: It is recommended to choose the combination of CIE standard light source D65 (simulating daylight) and a 10° viewing angle. 

Application Scenario Requirements: It is necessary to clarify the purchase purpose (quality inspection? R&D? material evaluation?) and the usage environment (laboratory, workshop or field work?).


CIELAB L*a*b* values are the most standardized units in the use of color measurement. These determine values of lightness (L*), red-green (a*), and blue-yellow (b*). The color differences between the two samples can be measured through ΔE.

Standard models are available in a range of sizes, starting from small desktop units which are roughly the size of 60 x 40 x 40 cm, and extending to larger units which are about 120 x 60 x 80 cm based on what you need them for.


A colorimeter is a scientific instrument used to measure and analyze the color characteristics of objects or materials. It quantifies color by evaluating specific parameters related to human visual perception and standardized color spaces.
