摘要： Disclosed is an image processing technique which more suitably reduces flicker noise. An image display device is comprised of an input unit which inputs encoded image data containing images encoded by intraframe prediction and interframe prediction, an image decoder which decodes the encoded image data, a filter unit which filters the decoded images output from the image decoder, and a display unit which displays the image after filtering. The filter unit performs at least a process to correct the pixel values in a decoded image decoded by interframe prediction immediately preceding in time a decoded image decoded by intraframe prediction of the decoded images output from the image decoder.

摘要： A lightweight metal mold having a necessary hardness is realized. A plurality of bar-shaped members formed of an evaporative material and a plurality of connecting members formed of an evaporative material are prepared. Each of the connecting members has a spherical shape, and ends of a plurality of the bar-shaped members can be connected to each connecting member. Since a fixing angle of each bar-shaped member with respect to the connecting member can be adjusted freely, a three-dimensional mesh structure having various shapes can be formed. By combining the plurality of bar-shaped members and the plurality of connecting members, an evaporative pattern including the three-dimensional mesh structure can be assembled. By adjusting the shape of the three-dimensional mesh structure, the hardness necessary for the metal mold can be obtained, and the metal mold can be made lighter.
