摘要： Aspects of the subject matter described herein relate to reducing error in images obtained from an image-acquiring system. An image-acquiring system may be modeled as light received from a primary path, light received from a secondary path, and light received from all other paths. Light received from the secondary and other paths may cause error in images captured by the image-acquiring system. By compensating for this light, the error may be reduced. Other aspects are described in the specification.

摘要翻译： 本文描述的主题的方面涉及减少从图像采集系统获得的图像中的误差。 图像获取系统可以被建模为从主路径接收的光，从次路径接收的光以及从所有其他路径接收的光。 从次要路径和其他路径接收的光线可能会导致由图像采集系统捕获的图像错误。 通过补偿该光，可能会降低误差。 其他方面在说明书中描述。
