The present invention provides an image display apparatus capable of suppressing deterioration in picture quality resulting from precision of detection of a motion vector at the time of performing a predetermined video signal process to improve picture quality. In consideration of reliability in detection of a motion vector mv by a motion vector detector 44, a video signal process in an interpolation section 45, an imaging blur suppression processor 13, and an overdrive processor 10 is performed. Concretely, the video signal process is performed so that a degree of the video signal process rises as reliability increases and, on the other hand, a degree of the video signal process falls off as the reliability decreases. In the case of performing the video signal process using a motion vector, even when a motion vector lies out of a motion vector search range (block matching range), the video signal process according to the motion vector detection precision can be performed.

The present invention relates to a shredder having a thickness triggering device. During the shredding operation, the trembling of the article is minimized or eliminated by using the shredder. The shredder includes a sustaining mechanism and a driving assembly. Since the sustaining mechanism is sustained against the shredding article, the amplitude of the trembling article is largely reduced. As a consequence, the influence of the shredding article on the thickness triggering device is reduced so as to prevent interruption of the shredder.

The invention discloses a lighting energy-saving control method based on a variable-gain Newton extremum search algorithm. The illumination requirement is maintained through PID closed-loop control, and at the same time, the lowest energy consumption of the lighting system is quickly found through continuous iteration through the variable-gain Newton extremum search algorithm. value, and keep the lowest value for stable output; in the variable gain Newton extreme value search algorithm, a positive signal is introduced to change the size of the gain, and the new gain obtained is a positive value of change, and the trend of change is to increase first and then decrease , when it is increased, the output of the algorithm will quickly approach the extreme point, and when it is decreased, the jitter degree of the output near the extreme point will be reduced, which not only shortens the search time, but also reduces the jitter degree when it tends to be stable ; At the same time, by adding a self-closed loop system, you can adjust the parameters to make the output more stable and fast. By adopting the invention, the speed and accuracy of the Newton extremum search algorithm can be improved, thereby improving the overall performance of the lighting energy-saving control method.
