Lecture
This lecture covers the importance of gamma correction in image formation systems, explaining the need for gamma correction, the technique involved, and providing a visual example. It discusses how a good image should have proper contrast and illumination, allowing the human eye to discern details clearly. The lecture also delves into the mechanism of gamma distortion, where the relationship between luminance and voltage is non-linear, affecting visual perception. Mathematical expressions and effects of gamma distortion are explored, along with the definition and method of gamma correction to compensate for undesired effects in image formation systems.
