DESCRIPTION (provided by applicant): The goal of the program proposed here is to create a head mounted binocular electronic magnifier which will be highly effective, attractive, lightweight, and which will offer minimal interference with the user's other activities. MicroOptical has developed binocular viewers with up to 16 degrees field of view which are offer a high quality, high contrast binocular image in a compact package with minimal impact on the user's peripheral vision. For the device proposed here we will develop a viewer with an expanded field of view of 20-24 degrees and incorporate a miniature CMOS camera into the bridge of the device. The camera lens will be designed to give 2x magnification. The drive electronics will provide electronic magnification, brightness and contrast, and potentially other image enhancements to improve the user's ability to discern details in the image. Simple user controls will allow convenient switching between digital zoom levels of 1, 2, and 4x for up to 8x magnification of the object of interest. Pilot trials will be used to evaluate the system's ergonomics, utility, and the potential for user acceptance.

描述（由申请人提供）：此处提出的计划的目标是创建一个头部安装的双眼电子放大器，该放大器将非常有效，有吸引力，轻量级，并且对用户的其他活动的干扰最少。微型电流已经开发了双眼观众，最多可见16度的视野，在紧凑的包装中提供高质量，高对比度的双眼图像，对用户外围的影响很小 想象。对于此处提出的设备，我们将开发一个查看器，其视野扩展为20-24度，并将微型CMOS摄像机置于设备的桥梁中。相机镜头将设计为2倍放大。驱动电子设备将提供电子放大，亮度和对比度，并可能提高其他图像增强功能，以提高用户在图像中识别细节的能力。简单的用户控件将允许在数字变焦级别1、2和4倍之间方便切换，以最大8倍的倍率放大。试验试验将用于评估系统的人体工程学，实用程序和用户接受的潜力。
