Light field cameras have been extensively used in a variety of applications, thanks to their snapshot three-dimensional imaging capability. However, little is known regarding their pros and cons for a given application. Herein we report a fundamental comparison between two types of light field cameras-focused and unfocused. Our results indicate that the unfocused light field camera outperforms its focused counterpart in depth range and number of resolvable depth steps, while the focused light field camera has an edge in lateral resolution and reconstruction accuracy.
由于具有快照三维成像能力，光场相机已在各种应用中得到广泛使用。然而，对于给定的应用，其优缺点却鲜为人知。在此，我们报告了两种类型的光场相机——聚焦型和非聚焦型——之间的基本比较。我们的结果表明，非聚焦光场相机在深度范围和可分辨深度步数方面优于其聚焦对应物，而聚焦光场相机在横向分辨率和重建精度方面具有优势。
