摘要： An image display device includes: an interpolation phase generator that generates an interpolation phase on the basis of downsampling frame information representing a downsampling timing at which at least one frame image of the image signal is thinned, and an interpolation frame generator that generates an interpolation frame image corresponding to the interpolation phase. The interpolation phase generator generates the interpolation phase such that a phase distance between a first interpolation frame image from among a plurality of interpolation frame images within one period of downsampling periods, and a second interpolation frame image that follows the first interpolation frame image becomes equal to a phase distance between mutually adjacent interpolation frame images obtained when phase distances between a plurality of interpolation frame images are equalized within one period of the downsampling periods.

摘要： In a control device for an internal combustion engine provided with a NOx catalytic converter in an exhaust passage thereof, the progress of an undesired substance removal process is computed from the consumption of the reducing agent contained in the exhaust gas in the NOx catalytic converter. The undesired substance may include sulfur contents and NOx captured in the NOx catalytic converter. This computation may be based on the air fuel ratio of the exhaust gas upstream of the NOx catalytic converter and the estimated consumption of the reducing agent contained in the exhaust gas or on the difference between the air fuel ratios of the exhaust gas upstream and downstream of the NOx catalytic converter. In either case, the accuracy can be improved by taking into account the space velocity of the exhaust gas.

摘要： An exhaust emission control device for an internal combustion engine, which is capable of supplying a just enough amount of reducing agent to a NOx catalyst, thereby reducing exhaust emission and improving fuel economy. The device includes a three-way catalyst, a NOx catalyst provided downstream of the three-way catalyst, and an ECU. The ECU carries out rich spike control such that exhaust gases flowing into the NOx catalyst form a reducing atmosphere. During the control, the ECU calculates a reducing agent consumption amount of reducing agent in the exhaust gases consumed by the three-way catalyst, calculates a cumulative reducing agent amount as a total amount of reducing agent supplied to the NOx catalyst, depending on the reducing agent consumption amount, and terminates the control when the cumulative reducing agent amount becomes larger than a predetermined value.

摘要： An exhaust emission control device for an internal combustion engine, which is capable of supplying a just enough amount of reducing agent to the NOx catalyst even when a catalyst is provided on an upstream side of the NOx catalyst. A catalyst and a NOx catalyst are disposed at respective upstream and downstream locations in an exhaust system, for purifying NOx and for trapping NOx under an oxidizing atmosphere and reducing the NOx under a reducing atmosphere, respectively. An air-fuel sensor is disposed between the catalyst and the NOx catalyst. A reducing agent is supplied to an upstream side of the catalyst, to control exhaust gases such that the gases form the reducing atmosphere. To determine time of termination of NOx reduction control, an amount of reducing agent supplied to the NOx catalyst is calculated, and calculation of the amount of reducing agent is started when the air-fuel ratio has converged within a vicinity of a target air-fuel ratio.

摘要： An exhaust emission control device for an internal combustion engine which is capable of supplying a just enough amount of reducing agent to a NOx catalyst while causing the consumption amount of reducing agent dependent on the degradation degree of an upstream catalyst to be reflected thereon. A NOx catalyst is disposed at a location downstream of a catalyst having an oxidation function for purifying exhaust gases, for trapping NOx contained in exhaust gases in an oxidizing atmosphere, and reducing the trapped NOx in a reducing atmosphere to thereby purify the trapped NOx. Exhaust gases flowing into the NOx catalyst are controlled to the reducing atmosphere, by supplying reducing agent to an upstream side of the catalyst. The degradation degree of the catalyst is estimated, and a time period over which the reduction control should be executed is corrected according to the estimated degradation degree.
