This short course covers the process of establishing baseline colorimetric camera characterization transforms along with subsequent individual unit production-line calibration to increase quality and yield while lowering cost. The need for camera characterization and calibration and the impact on general image quality is first reviewed. Known issues in traditional approaches are discussed. Methodology for building camera colorimetric transforms and profiles are detailed step-by-step. State-of-the-art solutions using current technology are presented including monochromators, multispectral LED light sources, in situ measurements of spectral radiances of natural objects, and modern color transform methods including multidimensional color look up tables. Practical considerations and methods for high-speed production-line camera module calibration are detailed. This short course provides the basis needed to implement advanced color correction in cameras and software as well as updating the relevant parameters in a production-line environment.
Learning Outcomes
- Understand the need for camera colorimetric characterization and the impact of color calibration on image quality and manufacturing yield.
- Perform target-based and spectral-based camera characterization.
- Solve for colorimetric camera transforms and build profiles using linear and nonlinear techniques.
- Evaluate current colorimetric camera characterization hardware and software technology and products.
- Implement production-line per-module camera color calibration solutions.
Intended Audience
Engineers, project leaders, and managers involved in camera image processing pipeline development, image quality engineering, and production-line quality assurance.
