Abstract: The present invention is directed to provide a signal discriminating device realizing signal discrimination which enables a more appropriate signal process to be performed according to a signal source and a state of an input video signal. The signal discriminating device includes: a comparing section comparing a motion magnitude between two fields of an input video signal with one or more predetermined motion magnitude patterns which are provided in correspondence with one or more signal sources, so as to determine one or more degrees of match or mismatch between the motion magnitude and the motion magnitude patterns; and a discriminating section discriminating a signal source of the input video signal in consideration of the degree of certainty or uncertainty of discrimination, the degree of certainty or uncertainty being determined on the basis of the degrees of match or mismatch determined in the comparing section.

Abstract: An object of the present invention is to provide a phosphor capable of improving the light emitting efficiency of a plasma display panel and restraining the deterioration of luminance and a change in chromaticity with the passage of time, and also provide a manufacturing method of this phosphor and the plasma display panel using this phosphor. To achieve this object, the surfaces of phosphor particles for a plasma display panel are covered with a metallic oxide generated by the hydrolysis of a metallic alkoxide. A manufacturing method of the phosphor particles for the plasma display panel is characterized in that the metallic alkoxide is attached to the phosphor particle surfaces and is burned. In this manufacturing method, the phosphor particle surfaces are covered with a close film of the metallic oxide. The plasma display panel uses the phosphor particles having surfaces covered with the metallic oxide.
