    摘要: A color temperature correction device corrects, in a display device that represents brightness of RGB of a video signal by a plurality of levels of gray scales, a color temperature of the video signal. The color temperature correction device includes: a recording means of storing a gray scale value conversion table for an input gray scale value of a video signal to set gray scale values for respective RGB, so that a consistent color temperature is maintained; and a gray scale value converting unit that converts the input gray scale value to set gray scale values, based on the gray scale value conversion table.

    摘要: A first video signal generation circuit newly generates pixels between pixels in a first progressive video field signal outputted by a first progressive video generation circuit, and outputs a third progressive video field signal. A second video signal generation circuit newly generates pixels between pixels in a second progressive video field signal outputted by a second progressive video generation circuit, and outputs a fourth progressive video field signal. A comparison circuit compares the third progressive video field signal and the fourth progressive video field signal, and outputs the result of the comparison as motion amount information. An output circuit synthesizes an intra-field interpolation signal and a frame interfiled interpolation signal on the basis of the motion amount information, and outputs a composite signal as a progressive video signal.

    摘要: An exhaust emission control device for an internal combustion engine, which is capable of accurately estimating the amount of NOx trapped by a NOx catalyst even when a catalyst is provided on an upstream side of the NOx catalyst. A catalyst having the function of purifying NOx and a NOx catalyst for trapping NOx under an oxidizing atmosphere are disposed in an exhaust system. The amount of NOx contained in exhaust gases is estimated. A NOx purification performance of the catalyst is calculated. The NOx emission amount is corrected based on the purification performance. An amount of NOx trapped in the NOx catalyst is calculated based on the corrected NOx emission amount. A reducing agent is supplied to an upstream side of the catalyst based on the trapped NOx amount, thereby causing the NOx catalyst to carry out a NOx reducing operation.
