Christian Perwaß, Lennart Wietzke. Single Lens 3D-Camera with Extended Depth-of-Field

Christian Perwaß, Lennart Wietzke. 2010. 15 p.Placing a microlens array in front of an image sensor transforms a regular camera into a single-lens 3D camera, allowing the user to change the focus and the point of view after a picture has been taken. While the concept of such plenoptic cameras is known since 1908, only recently the increased computing power of low-cost hardware and the advances in microlens array production, has made the application of plenoptic cameras feasible. This text presents a detailed analysis of plenoptic cameras as well as introduces a new type of plenoptic camera with an extended depth of field and a maximal effective resolution of up to a quarter of the sensor resolution.
