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

To extend the life of a haze meter, keep the instrument dust-free and clean, regularly calibrate it, and control for a stable dry storage. For better results, avoid letting the optics dry, and leave the meters under sunlight. For optimal performance, have the meter professionally serviced once a year.

Since part of the light will pass through the light-transmitting materials, the colorimeter is not suitable for color measurement of such kinds of materials; however, when place a pure color material with uniform texture under the light-transmitting material, we can measure the color difference between the standard and the sample. 

There are many factors that can influence accuracy such as surface roughness, temperature, substrate material, and calibration settings. For ferrous metals, external magnetic fields can also distort measurements. Proper calibration and preparation will help reduce the impact of these factors.


Usually you will find haze and transmittance standards of ASTM D1003, ISO 13468, & JIS K7105.


a. Right click "! USB Device" or "! SCI USB2Serial (COM6)", "Update Driver" -> "Install from a list or specific location (Advanced)" -> "Next" ->"Include this location in the search" -> "Browse", specify USB driver file path "CQCS3USB_Driver", click "Next". Then it will install successfully.

b.Detailed installation information please refers to "2.2 Installing USB Driver" in Color Quality Management System User Manual.doc.

Our haze meters provide consistent and accurate data as per the requirements of ASTM D1003, ISO 13468, and JIS K7105. Due to the high precision, advanced optics, and automatic calibrations, haze meters produce repeatable and precise results for glass, films, and plastics while remaining simple to operate.
