本文介绍了可编程成像系统的概念。这样的成像系统为人类用户或视觉系统提供了对系统的辐射和几何特性的重要控制。这种灵活性是通过可编程微镜阵列实现的。阵列反射镜的方向可以在空间和时间上进行高精度控制。这使系统能够根据手头应用的需要从场景的光场中选择和调制光线。我们实现了一个可编程成像系统，该系统使用数字微镜器件（DMD），用于数字光处理。虽然该设备的镜子只能定位在两种状态中的一种，但我们表明，我们的系统可以用来实现各种各样的成像功能，包括高动态范围成像、特征检测和目标识别。我们还描述了如何允许完全控制其镜子方向的微镜阵列可以用来立即改变成像系统的视场和分辨率特性。最后，我们讨论了可编程成像对计算机视觉的影响。
In this paper, we introduce the notion of a programmable imaging system. Such an imaging system provides a human user or a vision system significant control over the radiometric and geometric characteristics of the system. This flexibility is achieved using a programmable array of micro-mirrors. The orientations of the mirrors of the array can be controlled with high precision over space and time. This enables the system to select and modulate rays from the scene's light field based on the needs of the application at hand.We have implemented a programmable imaging system that uses a digital micro-mirror device (DMD), which is used in digital light processing. Although the mirrors of this device can only be positioned in one of two states, we show that our system can be used to implement a wide variety of imaging functions, including, high dynamic range imaging, feature detection, and object recognition. We also describe how a micro-mirror array that allows full control over the orientations of its mirrors can be used to instantly change the field of view and resolution characteristics of the imaging system. We conclude with a discussion on the implications of programmable imaging for computer vision.
