  • Patent number: 9623671
    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.

  • Publication number: 20160275076
    Abstract: In a wearable translation device, the control circuit obtains an audio signal of the second language, which has been converted from a first audio signal of the first language, and obtains a second audio signal of the first language reconverted from the audio signal of the second language. The first speaker device converts the audio signal of the second language into a first voice and outputs the first voice. The second speaker device converts the second audio signal of the first language into a second voice and outputs the second voice. The audio processing circuit executes such a process that the second voice from the second speaker device is directed toward an auditory part of a user, based on a position of the auditory part relative to the second speaker device.
