ColorSpace Completes Security Camera Image Quality Lab for Aztech in Malaysia

Evaluating the imaging quality of a security camera requires controllable illumination, test charts and target motion. For products built at volume, a laboratory has to measure sharpness, colour and noise under static conditions as well as verify imaging behaviour in dynamic scenes.

ColorSpace has completed the construction of an image quality test laboratory at Aztech Group Ltd's security camera production base in Malaysia.

The project addressed the image quality evaluation and performance verification requirements of security cameras, integrating test charts, lighting environments, chart switching, image analysis and dynamic testing so that product development, imaging performance verification and production quality management all have consistent test conditions.

01 | Building multi-dimensional image quality testing capability

The imaging performance of a security camera depends not only on the lens and sensor, but also on illumination, target motion and image processing. A laboratory therefore needs testing capability across several dimensions to evaluate products under different conditions.

The laboratory was built around three areas of testing capability:

Static image quality analysis: sharpness, colour, noise, dynamic range and distortion, providing quantitative data for performance evaluation and ISP tuning.

Dynamic performance testing: moving rails and automated motion mechanisms simulate dynamic targets, providing controllable conditions for motion blur, image smear and autofocus related tests, and helping evaluate imaging performance in dynamic scenes.

Test environment simulation: different lighting conditions and test distances support performance evaluation across imaging scenarios and improve the controllability and repeatability of test conditions.

Standardised test charts, lighting systems, an automatic chart switching device and image analysis software were integrated into a single cooperative test environment covering everything from test execution to data analysis.

02 | From equipment integration to testing capability

Building an image quality laboratory is not only about installing equipment: the test environment, test methods and analysis tools have to be planned around the product requirements so that the resources work together.

With this delivery, Aztech has strengthened its image quality testing and verification capability for security cameras and established a laboratory environment covering a wide range of test requirements.

03 | Supporting global imaging test requirements

From static image quality evaluation to dynamic performance verification, ColorSpace provides image quality laboratory solutions, automated test solutions and related technical services for a wide range of imaging products.

ColorSpace will continue to apply its experience in image quality testing to help customers improve test conditions and testing efficiency in product development and quality management.
