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种头戴式双目电子放大镜，该放大镜将非常有效、有吸引力、重量轻，并且对用户其他活动的干扰最小。 MicroOptical 开发了视野高达 16 度的双目观察器，在紧凑的封装中提供高质量、高对比度的双目图像，对用户外围设备的影响最小 想象。对于这里提出的设备，我们将开发一个视野扩大到 20-24 度的观察器，并将微型 CMOS 相机集成到设备的桥中。相机镜头将设计为提供 2 倍放大倍率。驱动电子设备将提供电子放大、亮度和对比度，以及可能的其他图像增强功能，以提高用户辨别图像细节的能力。简单的用户控制将允许在 1 倍、2 倍和 4 倍数字变焦级别之间方便地切换，以便将感兴趣的物体放大至 8 倍。试点试验将用于评估系统的人体工程学、实用性以及用户接受的潜力。
