Coded exposure photography

Coded exposure photography, also known as a flutter shutter, is the name given to any mathematical algorithm that reduces the effects of motion blur in photography. The key element of the coded exposure process is the mathematical formula that affects the shutter frequency. This involves the calculation of the relationship between the photon exposure of the light sensor and the randomized code. The camera is made to take a series of snapshots with random time intervals using a simple computer, this creates a blurred image that can be reconciled into a clear image using the algorithm. Motion de-blurring technology grew due to increasing demand for clearer images in sporting events and other digital media. The relative inexpensiveness of the coded exposure technology makes it a viable alternative to expensive cameras and equipment that are built to take millions of images per second.
