Disclosed are a primer composition having photochromic property and impact resistance for coating transparent materials and a photochromic transparent material having a primer layer formed by coating and curing the primer composition. The primer composition for coating transparent materials comprises: a) 5-90 parts by weight of a polyurethane containing Brønsted salt; b) 5-50 parts by weight of a polyepoxy resin; and c) 140 parts by weight of a photochromic dye, based on 100 parts by weight of the total primer composition. The photochromic transparent material having a primer layer formed by coating and curing the primer composition shows excellent photochromic property and impact resistance.
摘要:
An image processing apparatus and method are provided in which a reduced image is generated by removing some of a plurality of pixels of an original image. A pixel value of a pixel to be removed is reflected into a pixel value of an adjacent pixel and a reduced image is generated using the reflection result and the removal result.
摘要:
A method of estimating a mass of a vehicle. If a yaw rate is smaller than a reference value, a straight direction model algorithm is applied to obtain an estimated mass. If a measured speed and a measured steering angle are larger than reference values, a lateral direction model algorithm is applied to obtain another estimated mass. If a measured vertical acceleration is larger than a reference value, a vertical direction model algorithm is applied to obtain yet another estimated mass. If each of the estimated masses is in an allowable range, and is constant for a given time period, the masses are applied to a recursive least square method, thereby estimating the mass of the vehicle.

An image quality improving apparatus and method that distinguish an edge of an actual outline imagely recognized in an image inputted via an image input unit from those printed according to dither patterns, to emphasize the actual outline, and thereby acquire the image without distortion. The image quality improving apparatus comprises: a first unit estimating edge pixels of a text area in a predetermined detection area to be edge-detected from an input picture data containing a text and an image; and a second unit judging actual edge pixels based upon a number of edge-estimated pixels in a multiple window area and saturation values of individual edge-estimated pixels, and emphasizing individual actual edge pixels with different edge emphasis coefficients according to saturation values of the actual edge pixels.

Provided is a plasma display panel (PDP). The PDP includes a first substrate; a second substrate disposed parallel to the first substrate; partition walls disposed between the first and second substrates and for defining discharge cells in which gas discharge occurs; phosphor layers, each phosphor layer disposed in one of the discharge cells and formed by coating any one of red, green, and blue phosphors; and discharge electrodes for provoking gas discharge. In a unit pixel including three discharge cells in which respectively different phosphor layers are disposed, a pair of discharge electrodes, which cause gas discharge, are disposed such that the discharge electrodes cross the respective discharge cells positioned in the unit pixel, and the area in which the discharge electrodes cross at least one discharge cell is different from the area in which the discharge electrodes cross the other discharge cells.
