Title: Image quality estimation device, method, and program
Inventor: YAMAGISHI KAZUHISA
IPC: H04N19/196
Filed: 2008-04-08
Abstract: <P>PROBLEM TO BE SOLVED: To correctly estimate the quality of the image in which a burst packet loss includes occurred.  <P>SOLUTION: A packet loss frequency computation part 102 counts packet losses which have been generated in a predetermined interval expressing the interval of continuous IP packets as packet losses of one time from an extracted packet loss pattern, and computes the counted value as a packet loss frequency. Moreover, the computation part 102 computes a burst packet loss length expressing the number of continuously lost packets from the packet loss pattern. An average packet loss length within a quality estimation interval is computed from the burst packet loss length, and a packet loss variation index computation part 106 derives a packet loss variation index from the average packet loss length. Meanwhile, an encoding quality computation part 103 computes a first image quality value based on an extracted encoding bit rate and frame rate. An image quality estimation part 104 computes a second image quality value based on the first image quality value, the packet loss frequency, and the packet loss variation index.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Filed: 2008-04-11
Abstract: <P>PROBLEM TO BE SOLVED: To prevent breaking of a pinball nail caused by the metal fatigue by disposing a reinforcing part in a nail shaft part in the range not to be hit by a pinball ball.  <P>SOLUTION: The reinforcing part 4 is formed in the shaft part 2 of the nail 1 hammered on a panel 6 of the pinball machine, and in such a range as to be exposed from the surface of the panel 6 and to penetrate into the thick wall of the panel. The outer diameter of the reinforcing part 4 is larger than the diameter of the shaft on the head 2 side from the reinforcing part 4, and the height of exposure of the reinforcing part 4 from the surface of the panel with the nail 1 hammered on the panel 6 to a set depth is such a height and thickness that the pinball ball 7 moving on the surface of the panel can not interfere with the reinforcing part 4. Since the reinforcing part 4 of the nail 1 is formed in the part crossing the surface of the panel 6 where the stress is concentrated when the pinball ball 7 collides with the nail 1, the durability against the metal fatigue can be increased, and therefore, breaking of the nail 1 can be prevented and the life of the nail 1 can be extended.  <P>COPYRIGHT: (C)2010,JPO&INPIT
