  • Patent number: 10022983
    Abstract: An image processor, a printing apparatus, and an image processing method are provided that can reduce, when a plurality of types of inks are used to print an image, the color unevenness that is caused by the variation of ejecting characteristics among a pluralities of nozzles. To realize this, for a color formed by overlapping at least two colors of inks, parameters are prepared that are determined so as to reduce the color difference in the printing medium due to the variation of the ejecting characteristic among the respective pluralities of nozzles. During printing, the parameters are used to correct the first color signal owned by the individual pixels to the second color signal.

  • Patent number: 10013626
    Abstract: An acquisition unit acquires image data resulting from reading an image printed sequentially in a first direction. A setting unit sets a division size in the first direction and a second direction of a division area for dividing the image data, the second direction crossing the first direction, as well as a shift amount in the first direction and the second direction of the division area. A processing unit performs a predetermined process including an averaging process on the image data in accordance with the division size and the shift amount. An extraction unit extracts a unique portion from image data on which the predetermined process has been performed. The setting unit sets (i) the division size greater in the second direction than in the first direction, and/or (ii) the shift amount greater in the second direction than in the first direction.

  • Publication number: 20180096218
    Abstract: A signal processing method includes addition of noise obtained by multiplying generated random number by K to the input pixel signal I(x), a binarization process of comparing the result of the addition with two thresholds, and a process of calculating a probability. The binarization process includes a first nonlinear process and a second nonlinear process. The first nonlinear process outputs “P” in a case where I(x) after the addition of the noise is greater than the threshold T1 and less than the second threshold T2. The second nonlinear determines “1” or “0” for a processing target pixel, in which the result of the first nonlinear process is “P,” based on input pixel signals of pixels around the processing target pixel. The process of calculating a probability calculates a probability J(x) that the result of the first nonlinear process is “1,” or the result of the first nonlinear process is “P” and the result of the second nonlinear process is “1”.

  • Publication number: 20180039625
    Abstract: A translation device includes an input unit, a controller, a notification unit, an output unit, and a memory. The input unit inputs an utterance of a speaker to generate utterance data. The controller determines accuracy of a translation result when translated utterance data from the utterance data is obtained. The notification unit notifies the speaker of the determination result of the controller. The output unit outputs a translated utterance according to the translated utterance data. The memory stores dictionary data associating utterance data with translated utterance data. The controller performs translation based on the dictionary data. When the controller determines that the accuracy of the translation result is lower than a predetermined value, the controller controls the output unit not to output the translated utterance, and controls the notification unit to issue a notification regarding the determination result.
