Title:
- Multi-Focal Compound Eye: Liquid Lens Array for Computational Photography
Presenter(s):
Description:
We developed a novel imaging system that captures images through an array of variable-focus lenses. Since the focal length of each lens can be controlled independently, the system is called a ”Multi-focal compound eye”.
Several compound-eye cameras were developed for various applications such as image-based rendering and digital refocusing [Yamamoto et al. 2004; Ng et al. 2005; Georgiev et al. 2006]. However, those systems were implemented by using fixed-focus lenses. Furthermore, by using dynamic optical devices, our system introduces the concept of Programmable Imaging [Nayar 2006] to compoundeye cameras.
