摘要： Electronic devices having image-based data input systems are described. In one aspect, an electronic device includes a window, multiple indicia, an image sensor, and a data input processor. The window has a contact surface with an input region. The multiple indicia are viewable in the input region of the contact surface. The image sensor is constructed and arranged to produce image signals corresponding to images of the input region. The data input processor is coupled to the image sensor and is operable to produce input signals based on image signals produced by the image sensor and a mapping between areas of the input region images and locations of the input indicia.

摘要： A three-dimensional optical inspection system reconstructs a three-dimensional image of the shape of the surface of an at least partially specular object resident on a printed circuit board by capturing two or more two-dimensional images of the object under different illumination configurations. The diffuse reflection, as well as the specular reflection can be used to reconstruct the three-dimensional image using any reconstruction method, such as photometric stereo. The different illumination configurations can be achieved using an illumination source including light-emitting elements arranged in concentric circular arrays, in which each of the circular arrays is divided into sections. Each section is independently controlled to selectively activate the sections to illuminate the object in a pre-established illumination pattern.

摘要： A system and method for processing mosaiced or raw data images operates to concurrently demosaic and resize the mosaiced images in a combined process. The combined demosaic/resize process allows the system to perform demosaicing and resizing more efficiently than conventional systems, which perform these processes separately and sequentially. Furthermore, the combined demosaic/resize process allows the system to produce demosaiced and resized images of higher quality as compared to demosaiced and resized images produced by the conventional systems.

摘要： A two-color photo-detector capable of sensing two colors at a single photo-detector location is provided having a lower photo-detector element resident in the bulk silicon and an upper photo-detector element elevated above the lower photo-detector element. The color sensitivity of each of the photo-detector elements is determined according to the absorption curve of the upper photo-detector element, the thickness of the upper photo-detector element and the color filter array, if any. The elevated upper photo-detector element overlies the circuitry needed for both the upper photo-detector element and the lower photo-detector element. In order to accurately sample color within an array of two-color photo-detectors without a color filter array, two different thicknesses for the upper photo-detector elements of adjacent two-color photo-detectors are used. Therefore, each pair of two-color photo-detectors within the array senses four different colors (i.e., blue and the complement of blue and red and the complement of red). To process the raw color values for compression and storage, a simple color-conversion matrix can be used on a 2×2 block of two-color photo-detectors to convert the four colors (eight color values) to a new color space, such as YCbCr (4:1:1), without traditional demosaicing neighborhood operations.

摘要： A digital image system is disclosed having a sensor with an elevated two-color photo-detector for sensing two different color values in combination with a single-color photo-detector for sensing a third color value. Minimal demosaicing is performed to obtain at least one luminance value at each photo-detector location. The sampled chrominance values and sampled and demosaiced luminance values are directly compressed without converting between color spaces and with minimal or no processing required. With a reduced amount of image processing prior to image compression, all of the pre-compression image processing may be performed on the image sensor itself instead of on a separate image processing system.

摘要： A digital color image sensor is disclosed having an elevated two-color photo-detector in combination with a single-color photo-detector. At least part of the circuitry associated with the two-color photo-detector may be integrated under the single-color photo-detector, which results in a smaller and less expensive photo-detector for a color image sensor. In addition, the two-color photo-detector photo-detectors are electrically isolated from each other, thereby improving the dynamic range of each photo-detector. The isolation is achieved by implementing one of the photo-detectors of the two-color photo-detector within the bulk silicon and elevating the other photo-detector of the two-color photo-detector above the bulk silicon.
