  • Patent number: 10425645
    Abstract: The invention relates to the encoding of pixel blocks. To apply some encoding tools, an input 4:2:0 block is upsampled into a 4:4:4 block. Each color component of the 4:4:4 block has thus the same importance when evaluating a distortion measure. To vary the influence of the color components depending on their impact on the decoding, the invention provides assigning weights to the color components of pixels of the 4:4:4 block depending on whether the corresponding color components exist in the 4:2:0 block, due to the subsampling. In such a case, any measure is evaluated using the weighted color components. This approach may apply to the palette coding mode, for instance when updating the color component values of a palette entry upon building, or selecting the closest palette entry to a pixel currently considered, or also determining whether a palette entry predictor may be used instead of a palette entry.

    Abstract: Techniques are disclosed to identify a form document in an image using a digital fingerprint of the form document. To do so, the image is evaluated to detect features of the image and generate a boundary around each feature. For each boundary, dimensions of the boundary may be stored in a color channel of a pixel in a second image. Thus, the color of the pixel represents the size of the boundary. The second image is the digital fingerprint of the form. To identify the form corresponding to the digital fingerprint, the digital fingerprint may be compared to digital fingerprints of known forms.

  • Patent number: 9569808
    Abstract: A printing apparatus is provided with a plurality of analyzing units, and a control unit. Each of the plurality of analyzing units analyzes each of different pages of print data, and notifies an error in a case that an analysis error occurs. The control unit receives the error notification from the analyzing unit, at which the analysis error occurs, among the plurality of analyzing units. And, the control unit notifies a cancel to another analyzing unit at which the analysis error does not occur. The control unit is further configured to notify, on a condition that a printing of all pages before a page at which the analysis error occurs is completed, the cancel to the another analyzing unit.

  • Patent number: 9444950
    Abstract: A white reference plate includes in addition to a rectangular portion disposed at an optical adjustment position, white reference portions between an optical adjustment position and a document size detection position outside a document reading region (i.e., outside contact glass) in a main scanning direction. In response to an opening and closing detecting section detecting opening and closing of a document conveyance unit during optical adjustment, a drive section moves a scanning section from the optical adjustment position to the document size detection position. The white reference portions are disposed at locations above respective opposite end parts of the scanning section in a main scanning direction, so that optical adjustment can be performed using an output value that the scanning section obtains by reading the white reference portions without interruption even during or after the movement.

  • Patent number: 9387666
    Abstract: A method is provided for processing a relief raster image, comprising customary color channels for indicating a color of each pixel and a height channel for indicating a height of each pixel into several pass images that are printed using a printer with several colorants including a white colorant. For each pixel a relief part, a white part and a skin part are discriminated in order to combine the demands for height and color variation across the surface of the image. The skin part comprises pixels for which a colorant composition based on the color channels of the relief raster image is established. In order to print a color in the skin part that is independent of a height of the pixel, the relief part comprises an arbitrary colorant composition and the white part comprises mainly white colorant.
