Abstract: A system includes a computing device that includes a memory configured to store instructions. The system also includes a processor to execute the instructions to perform operations that include receiving, at an imaging device, one or more files representing a network asset that is presentable on a display of the imaging device. At least one of the files includes data for presenting textual content of the network asset. Operations also include presenting on the display of the imaging device a portion of the network asset and textual content that corresponds to the portion of the network asset.

Abstract: Provided is a method for font data streaming for time-based video/audio presentations where content is transmitted in small increments and transmission continues while a previously transmitted portion is viewed or played. Different subsets of characters of the same font are assembled together on a device and previously sent characters are reused for rendering subsequent text strings. Font subsets are created to provide only a minimal number of glyphs for the character set coverage, thereby reducing the redundancy of font data transmission and reducing the total number of characters transmitted.

Abstract: A method and apparatus are provided for embedding a font subset in an electronic document. The method in one form includes analyzing a document having characters of a font set where characters may have different forms depending on the location of the character in a word or one or more ligatures represent a combination of characters. A font subset is created corresponding to only the character forms present in the document and the font subset is associated with the document. Advantageously, the embedded font subset only contains the font characters which are used in the document and not all characters which may be present in a complete font set for all font sets referenced in the document.

Abstract: The automatic generation and use of halftone supercell threshold arrays suitable for high addressability output devices, particularly ones with constraints on sub-pixel combinations or geometries is disclosed. An example of a high addressability device is a laser printer using a pulse width modulator. The invention can further extend the usefulness of supercell halftone screening systems.

Abstract: At least two different pixel clock frequencies or pixel pitches are used when generating an image. They are used with periodic halftone patterns in a color scanning printing process. By using different clock frequencies for the different color separations, more options for screen geometry are available, and therefore new screen sets with desirable moiré behavior are possible. This is especially important on low resolution devices, such as 1200 dpi and below. Here there are a limited number of rational tangent screen geometries that are available and moiré canceling or moiré averting combinations are scarce. The different pixel clock frequency are used when writing at least two color channels in order to provide otherwise unavailable halftone geometries.

Abstract: An image sensor system comprises an array of pixels. Each of these pixels includes a light sensitive element that generates a pixel signal that is indicative of the amount of light received by that pixel. A comparator then compares the pixel signal to a reference signal and generates a strobe signal in response to this comparison, while a global counter generates a count across a shutter period. Finally, an array of memory elements is provided. Each of these memory elements stores a count from the global counter in response to receiving the strobe signal from the corresponding pixel of the array of pixels. As a result, the array of pixels has relatively little logic functionality. Each pixel need only contain the light sensitive element and the comparator. Thus, the system can provide a good fill factor. Further, the global counter can be shared across the entire memory array. It is most applicable to implementation in CMOS technology.

Abstract: A method of adaptive spatial filtering for enhancing digital images is presented. A window is applied to a source pixel to generate an array of windowed pixels. An upper threshold value and lower threshold value corresponding to the maximum and minimum pixel values, respectively, in the array of windowed pixels are determined. A spatial frequency filter is applied to the array of windowed pixels to generate a filtered array of pixels including a reference pixel. The values of the source pixel and the reference pixel are scaled by respective weighting factors and then combined to create an enhanced pixel value. If the enhanced pixel value exceeds the upper threshold value, the enhanced pixel value is replaced by the upper threshold value. Similarly, if the enhanced pixel value is less than the lower threshold value, the enhanced pixel value is replaced by the lower threshold value.

Abstract: A method for enhancing a digital image for printing or display on a high resolution device is described. The method includes receiving a digital source image and selecting a block of source pixels from the image. An edge array is generated from edges detected in the block of source pixels and processed with a set of logic operations to detect one of a set of edge patterns. The source coordinate system is transformed into a second coordinate system in response to the detected edge pattern and a transformed source location for the output pixel is determined. A modified transformed source location is determined by applying a modifier function. The modifier function is selected from a set of functions in response to the detected edge pattern. An effective source location is generated by applying a reverse transformation. The value of the output pixel is interpolated from the values of the block of source pixels based on the effective source location.

Abstract: A method of recovering a pixel clock for generating a digital image from an analog video signal is presented. The on and off-transition times for the active video portion of a digital image and the image size defined in a video standard are used to generate a pixel clock. The analog video signal is digitized according to the pixel clock and the image size of the resulting digital image is compared with the image size defined in the video standard. The pixel clock frequency is adjusted in response to the image size comparison. The optimum phase of the pixel clock relative to the analog video signal is determined through a repetitive phase adjustment technique. A first image coordinate is determined for a pixel clock at one phase and a subsequent image coordinate is determined for a pixel clock after decrementing the phase of the pixel clock. The first image coordinate and the subsequent image are compared.
