DIGITAL VIDEO CAMERA FOR LOW-VISION AIDS

描述（来自研究者摘要）：一种新型的 摄像机将用于基于计算机的低视力辅助设备。的 相机将能够清晰地成像书籍和弯曲的物体， 聚焦、照明或对比度所需的患者调整。图像 将在低分辨率真实的时间模式下进行数字增强， 更高分辨率的捕获模式。 这些能力将使 数码相机取代电视摄像机和图像扫描仪， 电子放大镜和阅读机的应用，结合 CCTV的优势，如鸟瞰和实时成像与 数字扫描仪的精度和分辨率，成本与 现有的低端商业扫描仪和便携式包装。

DESCRIPTION (from investigator's abstract): A prototype of a new type of camera will be constructed for use in computer based 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 higher resolution capture mode. These capabilities will enable the digital camera to replace both television cameras and image scanners in electronic magnifier and reading machines application, combining the advantages of CCTV-like overhead viewing and real-time imaging with the accuracy and resolution of digital scanners, at cost comparable to existing low-end commercial scanners and in a transportable package.
