    • Devices, methods, and software are disclosed for capturing a frame of image data having a representation of a feature. In an illustrative embodiment, a device includes an imaging subsystem, one or more memory components, and a processor. The imaging subsystem is capable of providing image data representative of light incident on said imaging subsystem. The one or more memory components include at least a first memory component operatively capable of storing an input frame of the image data. The processor is in communicative connection with executable instructions for enabling the processor for various steps. One step includes receiving the input frame from the first memory component. Another step includes generating a reduced resolution frame based on the input frame, the reduced resolution frame comprising fewer pixels than the input frame, in which a pixel in the reduced resolution frame combines information from two or more pixels in the input frame.
    • 公开了用于捕获具有特征表示的图像数据的帧的装置,方法和软件。 在说明性实施例中,设备包括成像子系统,一个或多个存储器组件和处理器。 成像子系统能够提供表示入射在所述成像子系统上的光的图像数据。 一个或多个存储器组件至少包括可操作地存储图像数据的输入帧的第一存储器组件。 处理器与可执行指令通信连接,以使处理器能够进行各种步骤。 一步包括从第一存储器组件接收输入帧。 另一步骤包括基于输入帧生成降低分辨率的帧,所述缩小分辨率帧包括比输入帧少的像素,其中所述降低分辨率帧中的像素组合来自所述输入帧中的两个或更多像素的信息。

    • Devices, methods, and software are disclosed for an interactive user interface for capturing a frame of image data having a representation of a feature. In an illustrative embodiment, a device includes an imaging subsystem, one or more memory components, and one or more processors. The imaging subsystem is capable of providing image data representative of light incident on said imaging subsystem. The one or more memory components include at least a first memory component operatively capable of storing an input frame of the image data. The one or more processors may be enabled for performing various steps. One step may include receiving the image data from the first memory component. Another step may include attempting to identify linear features defining a candidate quadrilateral form in the image data. Another step may include providing user-perceptible hints for guiding a user to alter positioning of the device to enhance a capability for identifying the linear features defining a candidate quadrilateral form in the image data.
    • 公开了用于捕获具有特征表示的图像数据的帧的交互式用户界面的装置,方法和软件。 在说明性实施例中,设备包括成像子系统,一个或多个存储器组件以及一个或多个处理器。 成像子系统能够提供表示入射在所述成像子系统上的光的图像数据。 一个或多个存储器组件至少包括可操作地存储图像数据的输入帧的第一存储器组件。 一个或多个处理器可以被启用以执行各种步骤。 一步可以包括从第一存储器组件接收图像数据。 另一步骤可以包括尝试识别在图像数据中定义候选四边形形式的线性特征。 另一步骤可以包括提供用户可感知的提示,用于引导用户改变设备的定位以增强用于识别在图像数据中定义候选四边形形式的线性特征的能力。
