  • Publication number: 20130155042
    Abstract: An image correction data generating system for a display panel that uses unpolished glass is equipped with a signal generator, an imager, and a controller. The signal generator supplies the display panel with a signal for causing that display panel to output an image. The imager captures an output image. The imager is able to resolve an area smaller than the individual pixel sizes of a plurality of pixels. The controller is equipped with an instructing unit, an image acquirer, a high-pass filter, and a correction data generator. The instructing unit outputs instructions for supplying a signal value shared across the entire surface of the display panel to the signal generator. The image acquirer acquires output image data from the imager. The high-pass filter computes high-pass data by applying high-pass filtering to the output image data. The correction data generator outputs an image correction table corresponding to the high-pass data.

  • Publication number: 20120251767
    Abstract: A honeycomb structure includes a plurality of honeycomb fired bodies. Each of the plurality of honeycomb fired bodies is combined with one another by an adhesive layer interposed between the honeycomb fired bodies to form a ceramic body. Each of the honeycomb fired bodies has a peripheral wall around each of the honeycomb fired bodies and has a plurality of cells each of which extends along a longitudinal direction of the honeycomb fired body and in parallel with one another. The cells are separated from one another with a cell wall disposed between the cells. The ceramic body includes at least one center-high-heat-capacity honeycomb fired body which is a honeycomb fired body having a heat capacity per unit volume in a central part in a plane perpendicular to the longitudinal direction larger than a heat capacity per unit volume in a peripheral part in the plane.
