Course Description
This course describes the color imaging challenges created by the unique characteristics of compact camera modules, including AR/VR, automotive, machine vision, and consumer applications. First introduced are the fundamentals of camera optics in small formats for which the availability of suitable materials impacts color quality. Steep chief ray angles result in spatially varying spectral sensitivity and interact with the goniometric properties of IR-cut filters, dielectric materials, sensor microlenses, color filter array crosstalk, and color shading. Also covered are spherical aberration, spherochromatism, extended-depth-of-field imaging, sharpness transport algorithms, and the design of lenses in which axial color is used to ensure all color planes are in focus. The course gives the attendee an understanding of the physics and interaction of light, optics, and color as well as the algorithmic foundations for image signal processors in which the optics and ISP are jointly designed with the goal of improving the overall system image quality.

Intended Audience: engineers, project leaders, and managers involved in camera image processing, pipeline development, image quality engineering, and production-line quality assurance, and those who want to understand the challenges of compact camera optics.
