Real-Time Liquid Lens Focusing
Speed of traditional focusing algorithms is often limited by a bottleneck which is a mechanical movement of stepper motor, that moves a lens towards or away from cameras image sensor. The liquid lens technology promises to solve that issue by eliminating the need for mechanical movement, speeding up systems using it significantly. The main purpose of this thesis is to confirm or disprove that claim and to state the exact figures obtained from testing. To put the liquid lens to a practical test, an image-based auto-focus algorithm will be implemented and executed on camera systems using liquid and electromechanical lenses. An image-based auto-focus algorithm captures and processes the images at different focus values in order to calculate score of their sharpness and find its maximum.
