摘要： An error diffusion process adds an error value to an input grey image value to produce a modified input grey image value before comparing the modified input grey image value with a predetermined threshold value. A rendering value and error is generated based on the comparison. An error equal to the modified input grey value is generated when the modified input grey value is less than the predetermined threshold value, and an error equal to the modified input grey value minus a black reference value is generated when the modified input grey value is equal to or greater than the predetermined threshold value. This error value is further compensation for pixel growth when the output of the previously processed pixel is not equal to the output of the presently processed pixel.

摘要： A method and system electronically fuzzy classify a pixel belonging to a set of digital image data with respect to a membership of the pixel in a plurality of image classes. This process determines a fuzzy classification of the pixel and generates an effect tag for the pixel based on the fuzzy classification determination. Each class is defined by a set of heuristic rules such that the image classes are non-mutually exclusive. The heuristic rules are a set of conditions that define the membership value of the pixel within a certain class, thereby allowing a pixel to have a membership value in every possible image class.

摘要： A method and apparatus is presented for registering a plurality of color images formed on a photoconductive member in a process direction. The registration is enabled by a feedback loop wherein the phase and frequency of start-of-scan signals and a stable reference output signal are compared to produce an error signal representing frequency differences between the rotating polygons associated with each Raster Output Scanner. In one embodiment, the stable reference frequency is generated as a digital value by a microcontroller. In another embodiment, the digital value to be compared with the start-of-scan signal is generated by an encoder which provides a signal representing the motion of the moving photoconductive member. With either reference frequency, an error signal is generated which is applied as a pulse width modulated signal to the polygon drive motors to change the speed and frequency of the associated rotating polygon and, the speed, in turn, changing the SOS signals to complete the feedback loop. The process is iterative with pulse width modulated correction signals being applied until the comparison of the digital values representing the reference frequency and the SOS signals is reduced to zero. In a third embodiment, a phase correction circuit is described to enable subpixel registration.

摘要： A system for determining the cumulative position and periodic average velocity of a rotating body having an incremental encoder, operatively connected to the body, for generating a series of periodic signals indicative of rotation of the body. The system also includes a high frequency clock for generating clock pulses at a frequency greater than the maximum frequency of the encoder signal, and a timer for controlling the total time of a predetermined sample interval. Also included in the device is a counter for accumulating the number of integral encoder signal cycles that have been completed, an arithmetic logic unit for determining the size of a fractional portion of an encoder signal cycle that was completed between the last integral encoder cycle and the end of the sample interval. Subsequently, the number of integral encoder signal cycles is added to the fractional portion of an encoder cycle to determine the total number of encoder signal cycles completed, whereby the total is then multiplied by an encoder position conversion factor to determine the cumulative position of the rotating body or belt driven therefrom.

摘要： Disclosed is a processor-implemented method for processing images. The processor receives image data of a color space defined by input provided to a system by a user, determines at least one color attribute of the pixels in the received image correlating to at least perceptual image characteristics, determines statistics using the attribute(s), and analyzes the statistics to classify the image into a category. Based on at least the category, a billing structure for the image is determined. For example, chroma and/or hue of pixels can be used to create histograms, whose data is used to determine a degree of color and/or content of an image, which is categorized. Color space components of received pixels can also be statistically analyzed. Such determinations consider billing based on human perception of use of color. Billing for color images in this manner satisfies the user and increases use of color output (e.g., printing).

摘要： When estimating distance to an object in an image using a single camera, data acquired by an onboard accelerometer is analyzed to determine camera speed as the user takes a video of the object of interest. The compression that results during video processing is used to derive motion vectors for the object of interest in the scene. The motion vectors have an opposite direction to the camera motion and a magnitude that is a function of the unknown object distance and a known magnification level. The object distance is calculated from the estimated velocity and motion vector magnitude.

摘要： A system determines the noise level of image data by high pass filtering image data. Absolutes values of the high pass filtered image data are determined. Thereafter, multiple mean values for absolute values less than a predetermined number of threshold values are determined. Based upon the determined mean values, a plurality of estimated mean values is calculated, each estimated mean value being calculated from a combination of two determined mean values. The noise of the image is determined from a combination of the minimum estimated mean value and the maximum estimated mean value. This noise can be optionally used by a sigma filter, at Step S740, to sigma filter the image data.

摘要： A method adapts image data using more than eight bits per pixel to be compatible with devices using only 8-bit per pixel data. The method separates the higher bit depth data into an 8-bit image data stream, the balance of the bits are carried in a separate tag data stream. The 8-bit image data stream can be used in legacy devices that can handle only 8-bit data, and the tag data stream can be used in legacy devices that incorporate a tag data stream for their internal image processing.
