(EN) During an information-extraction technique, a user of an electronic device may be instructed by an application executed by the electronic device (such as a software application) to acquire images, with different orientations (which are known to the user), of a target location on a document using an imaging sensor, which is integrated into the electronic device. After the user has taken a first image and before the user takes a second image in a different orientation of the electronic device (and, thus, the imaging sensor), the electronic device captures multiple images of the document. Then, the electronic device stores the images with associated timestamps. Moreover, after the user has taken the second image, the electronic device analyzes one or more of the first image, the second imageand at least a subset of the images to extract information proximate to the target location on the document.
(ZH) 在信息提取技术期间,可以通过由电子设备执行的应用程序(诸如软件应用程序)指示所述电子设备的用户使用被集成到电子设备中的成像传感器,来以不同取向(其对于用户是已知的)获取文件上目标位置的图像。在所述用户已经拍摄第一图像之后并且在所述用户拍摄所述电子设备(以及从而成像传感器)的不同取向中的第二图像之前,所述电子设备捕获所述文件的多个图像。然后,所述电子设备存储所述图像与关联的时间戳。而且,在用户已经拍摄所述第二图像之后,所述电子设备分析所述第一图像、所述第二图像和至少所述图像的子集其中的一个或多个,以提取接近于所述文件上的目标位置的信息。
