A prototype of a new type of video camera will be constructed for use in low-vision aids. The camera will be capable of clearly imaging books and curved objects with no patient adjustment required for focus, illumination or contrast. Images will be digitally enhanced in both low resolution real-time mode and high resolution capture mode. These capabilities will enable the digital camera to replace both television cameras and image scanners in electronic magnifier and reading machine applications, combining the advantages of CCTV-like overhead viewing and real-time imaging with the accuracy and resolution of digital scanners, at a cost comparable to existing low-end commercial scanners, and in a transportable package. The Phase II program will produce a complete prototype camera with integrated "intelligent" magnifier, and will include extensive testing of human factors with low-vision patients.

一种新型摄像机的原型将被建造用于 低视力辅助设备。 该相机将能够清晰地成像书籍， 弯曲的物体，不需要患者调整聚焦， 照明或对比度。 图像将在两个低 分辨率实时模式和高分辨率捕获模式。 这些 数码相机将取代电视， 电子放大镜和阅读机中的照相机和图像扫描仪 应用程序，结合CCTV一样的优势，俯视观看， 具有数字扫描仪的精确度和分辨率的实时成像， 成本与现有的低端商业扫描仪相当， 可运输包装。 第二阶段计划将产生一个完整的 原型相机与集成的“智能”放大镜，并将 包括对低视力患者进行广泛的人为因素测试。
