  • Dispenser bottle including a conduit partition assembly, and an image forming device including the same
    Patent number: 7116930
    Abstract: Dispenser conduit partitions are used to improve the discharge flow of toner particles from a toner dispenser bottle in a host image forming device. A dispenser conduit partition assembly is inserted into the funnel-like dispenser conduit of the toner dispenser bottle. The conduit partition assembly is arranged with multiple partition members. The multiple partition members act to partition the single symmetric dispenser conduit into a corresponding multiplicity of asymmetric dispenser component conduits. As a result, the toner particles are dispensed by the multiple dispenser component conduits to thereby form a corresponding multiplicity of asymmetric toner particle discharge flows, thus reducing toner bridging.

  • System and method for measuring and quantizing document quality
    Patent number: 7116802
    Abstract: Text, images, and/or graphics of electronic documents should be organized and laid out in a two-dimensional format for presentation to the viewer. The best such layout depends upon the content present, the creator's intent, the output device, and the viewer's interests. To analyze the qualitative nature of the layout in quantifiable terms, the electronic document is measure using various quantifiable factors; such as, balance, uniformity, white space management, alignment, consistency, legibility, etc.; that impact a qualitative nature of a document. Such quantifiable factors are then used to quantize the aesthetics, ease of use, eye-catching ability, interest, communicability, comfort, and convenience of the document.

  • Apparatus for correcting ink droplets placement errors for recording apparatus, recording apparatus having apparatus for correcting ink droplets placement errors, and method for correcting ink droplets placement errors
    Patent number: 7114792
    Abstract: Ink droplets placement errors of a recording apparatus is to be corrected with high accuracy. Ink droplets placement errors in a subsidiary scanning direction of recording head units of a recording head array are obtained based on a result identified by reading a test chart for adjusting head alignment for detecting the errors, and it is then determined as to whether or not the errors identified is in a prescribed tolerance level (i.e., whether or not the printing result is good). In the case where it is judged that the printing result is not good, adjustment of alignment is carried out based on the errors identified. That is, the ink discharging timing of the recording head units is controlled per the period of the printing pulses, and the ink discharging timing of the recording head units is then controlled per the period of the controlling pulses.

  • Neutral pixel detection using color space feature vectors wherein one color space coordinate represents lightness
    Patent number: 7116443
    Abstract: A method for neutral pixel detection using color space feature vectors wherein one color space coordinate represents lightness is provided. The method includes the following steps: a) receiving an input image represented in a first color space; b) converting the input image to a second color space wherein one coordinate represents lightness; c) selecting a pixel in the second color space representation to be classified; d) computing second color space feature vectors associated with the selected pixel; and e) classifying the selected pixel between neutral and color classes based on the values computed for the second color space feature vectors. Typically, the input image is processed using a smoothing filter to create a smoothed input image prior to the conversion to the second color space. The method can be adapted to page processing or strip processing schemes with respect to the input image.

  • Image processing apparatus and image processing method
    Publication number: 20060215187
    Abstract: An image processing apparatus sequentially reduces a document, while changing the reduction factor step-by-step. Next, the image processing apparatus refers to the characters that constitute the document that has been reduced with the respective reduction factors, and specifies a reduction factor at which blank regions surrounded by line portions that express each character do not disappear. When an appropriate reduction factor is specified, the image processing apparatus specifies a resolution of the characters for that reduction factor, and converts the resolution of the document data to that specified resolution. Then, the image processing apparatus performs various processing for the document data whose resolution has been converted. Thus the resolution of document data is converted such that the document is reduced with a reduction factor suitable for computer processing.
