    • This invention is a hand-held and self-contained electronic scanning apparatus (10) for scanning information on a document (D) disposed outside the apparatus (10) that includes a housing (12) that can be manually positioned adjacent a surface of a document (D) and manually swept across a scanning area on the medium during a scanning sequence. The scanner disposed in the housing (12) contains a scan head with a plurality of scan elements such as light sensitive elements for scanning information such as an image on a document (D) within the scanning area. An electronic control circuit is also disposed in the housing (12) for controlling the scanner to scan information on the document (D) during a scanning sequence. The control circuit comprises compensation means for reducing image distortion based on detecting the position of the light sensitive elements during a scanning sequence.
    • 本发明是一种用于扫描设置在设备(10)外部的文档(D)上的信息的手持且独立的电子扫描设备(10),该文档(D)包括壳体(12),壳体可以手动定位在邻近 文档(D),并且在扫描序列期间手动扫描介质上的扫描区域。 设置在壳体(12)中的扫描仪包含具有多个扫描元件的扫描头,诸如用于扫描扫描区域内的文档(D)上的图像的信息的光敏元件。 电子控制电路还设置在壳体(12)中,用于在扫描顺序期间控制扫描仪扫描文档(D)上的信息。 控制电路包括用于基于在扫描顺序期间检测光敏元件的位置来减少图像失真的补偿装置。
