    • Methods and devices for implementing hyperacuity sensing are provided. The imaging device comprises a sensor array including sensor elements, each of which provides intracellular spatial intensity distribution information necessary to render images with subpixel accuracy. The method includes the step of hyperacuity sensing implemented using sensors that output signals that are dependent upon the internal intensity distribution of impinging light. The output signals are processed to determine the internal intensity distribution, which can then be used to produce a hyperacuity image. Such a hyperacuity image has enhanced definition of edges, and reduced artifacts such as jaggies and moire effects.

    • Bands of predetectors (92) detect the approach of lines of glyphs (12, 14) within an image being scanned. Linear lines or arrays of glyph detectors (116, 118, 120) are sampled in accordance with the detected approach of lines of glyphs. Each detector array includes a plurality of analog glyph detectors (20, 50) which respond to the presence of glyphs with a characteristic analog output. Preferably, the glyph detectors generate a corresponding analog output of a first polarity or other characteristic in response to glyphs of a first orientation and an output of a second polarity or characteristic in response to glyphs of a second orientation. The analog signals which are characteristic of the detection of a glyph are converted into binary 1's and 0's in accordance with the polarity or other characteristic of the signals. In this manner, glyphs are detected by analog detectors and the information encoded in the glyphs is directly output as a binary signal without computer analysis of the image.

    • A sensor array includes includes multiple sensor elements that each have a collection electrode in contact with a photosensitive layer. The photosensitive layer is configured to produce a detectable response at the collection electrode upon incidence of radiation in a responsive zone of the photosensitive layer. A gate electrode layer is separated from the photosensitive layer by a dielectric layer, with adjustments to voltage applied to the gate electrode layer inducing changes in areal extent of the responsive zone of the photosensitive layer. Changing the size of the responsive zone permits performance of image convolutions for edge detection, data compression, or other Gaussian convolutions by the sensor array, rather than by post-detection electronics.
    • 传感器阵列包括多个传感器元件,每个传感器元件具有与感光层接触的收集电极。 感光层配置成在感光层的响应区域中辐射入射时在收集电极处产生可检测的响应。 通过电介质层将栅极电极层与感光层分开,调整施加到栅电极层的电压,引起感光层响应区的面积范围的变化。 改变响应区域的大小允许通过传感器阵列而不是后检测电子装置执行用于边缘检测,数据压缩或其他高斯卷积的图像卷积。
