​Color reproduction from digital cameras is taken for granted by most people. Today’s digital consumer cameras capture sharp, color-enhanced images with the help of their integrated automated features.

However, these automated features are not suitable in areas demanding exact color reproduction for reproducibility, including diagnosis, research and manufacturing applications.

The Challenge

Accurate color matching poses challenges for consumer product manufacturers. They are often manufacturing products that demand color consistency from the start of the process to the final product off the line.

Products manufactured at different months need to have exactly the same color as a previously built product.

Hence, manufacturers have to ensure that their products are in line with the exact color requirements of their customers. In addition, they must ensure the color consistency in all parts of a product over its life cycle.

A great challenge for manufacturers of consumer products is accurate color matching.

A great challenge for manufacturers of consumer products is accurate color matching.

The Solution

The solution is a pantone color matching validation system employing high resolution, quality cameras that can deliver outstanding, consistent color reproduction in images captured by the camera.

The outputs are high-resolution images to a central computer equipped with custom software. An accurate color matching analysis is then performed using the custom software.

Requirements of High Performance Cameras

The following are the requirements of these high performance cameras:

  • Advanced demosaicing techniques for truer color reproduction
  • Multi-point controls for modulating color parameters
  • Accurate color correction matrices (CCM) for high color accuracy
  • Customized matrices might be needed in some cases
  • Low noise and high dynamic range for detection of color hues and intensities
  • Exact representation of colors in captured images, thanks to outstanding color/white balance functions

Exact color reproduction is an essential capability in life science applications for valid research data or diagnosis. In addition, it is essential to select and configure an appropriate camera (for instance, white balance) prior to capturing images.

Conclusion

The cameras designed and manufactured by Lumenera provide accurate and consistent color reproduction by meeting these requirements. The company ensures reliable imaging results for applications where color is critical, irrespective of factors that are not under the control of manufacturers such as working environments and lighting conditions.
