  • Patent number: 10701330
    Abstract: An image capturing unit captures an image including an embedded image that is printed on the basis of image data in which at least a color component has been modulated according to additional information. An adjustment unit adjusts a white balance of the image captured by the image capturing unit on the basis of an adjustment value associated with the embedded image. A processing unit processes image data of the image captured by the image capturing unit whose white balance has been adjusted by the adjustment unit to read the additional information in the image captured by the image capturing unit.

  • Publication number: 20200174316
    Abstract: The present invention provides a liquid crystal display device which has a high luminance and consumes less power by increasing the utilization efficiency of light. The liquid crystal display device includes: a first absorptive polarizing plate; a liquid crystal panel including a first substrate, a liquid crystal layer, and a second substrate in order from the first absorptive polarizing plate side; a second polarizing plate; and a backlight unit including a reflector in the stated order. The second substrate includes a reflective layer facing the second polarizing plate. A transmittance of polarized light vibrating in a direction parallel to a transmission axis of the second polarizing plate is greater than a transmittance of polarized light vibrating in a direction parallel to a transmission axis of the first absorptive polarizing plate.

  • Patent number: 10628123
    Abstract: After starting output of an audio guidance at a first volume, a control portion judges whether or not an image of a user is contained in image data, and also judges whether or not a cover has been opened, such that if no image of the user is contained in the image data and the cover is in a closed state, the control portion maintains the volume of the audio guidance at a first volume, whereas even if no image of the user is contained in the image data, when the cover is opened, the control portion changes the volume of the audio guidance to a second volume.

  • Publication number: 20200099821
    Abstract: An image processing apparatus generates a binary image from a multivalue input image, detects a character region and a non-character region from the binary image, and clips regions surrounding each of characters included in the detected character region as character clipping rectangles. The apparatus determines, on the basis of a black pixel density of the binary image included in the character clipping rectangle, whether or not the character clipping rectangle is a character region and determines, on the basis of a number of pixels included in the character clipping rectangle determined to be a non-character region, whether or not the character clipping rectangle determined to be a non-character region is a character region.

  • Patent number: 10522080
    Abstract: In a data line drive/current measurement circuit, m measurement units are disposed in a plurality of semiconductor chips such that the m measurement units are distributed among the plurality of semiconductor chips. A display apparatus includes transistors such that one transistor is provided for two adjacent semiconductor chips. Inter-chip correction data indicating a variation among the semiconductor chips in terms of characteristics of elements in the measurement units is determined based on a result of a current measurement performed for the same transistor using measurement units disposed in different semiconductor chips. The inter-chip correction data is stored in a storage unit and is used in correcting an image signal. The inter-chip correction data may be determined based on a result of measuring a current flowing through a common cathode of organic EL elements for each semiconductor chip.
