Abstract: An adaptive depth sensing system (ADSS) illuminates a scene with a pattern that is constructed based on an analysis of at least one prior-generated depth map. In one implementation, the pattern is a composite pattern that includes two or more component patterns associated with different depth regions in the depth map. The composite pattern may also include different illumination intensities associated with the different depth regions. By using this composite pattern, the ADSS can illuminate different objects in a scene with different component patterns and different illumination intensities, where those objects are located at different depths in the scene. This process, in turn, can reduce the occurrence of defocus blur, underexposure, and overexposure in the image information.

Abstract translation: 自适应深度感测系统（ADSS）利用基于至少一个先前生成的深度图的分析构建的图案来照亮场景。 在一个实现中，该图案是包括与深度图中的不同深度区域相关联的两个或多个分量图案的复合图案。 复合图案还可以包括与不同深度区域相关联的不同照明强度。 通过使用这种复合图案，ADSS可以照亮具有不同组件图案和不同照明强度的场景中的不同对象，其中这些对象位于场景中的不同深度。 这个过程又可以减少图像信息中散焦模糊，曝光不足和过度曝光的发生。
