This lecture overviews Image Formation, which is of primary importance in ensuring image quality and enabling image processing. It covers the following topics in detail: Light reflection models. Camera structure and models, e.g., Pinhole Camera. Camera Lenses. Image Formation Models. Optical sensors, e.g., CCDs. Image scanners. Image acquisition issues: gamma correction, while balance. Image quantisation and digitisation. Probabilistic Image Description. Image noise and noise generators.
