    摘要: A steel sheet for an inner magnetic shield has a ratio of the anhysteretic magnetic permeability in the rolling direction to the anhysteretic magnetic permeability in the transversal direction, which is not higher than 0.7 or not lower than 1.4, preferably not higher than 0.5 or not lower than 2.0. A higher value of the two anhysteretic magnetic permeability values in the rolling direction and in the transversal direction is not lower than 18000. The inner magnetic shield formed of the particular steel sheet has a substantially truncated pyramid body which has a pair of short side members of a screen and a pair of long side members of a screen. The short side members are joined to the long side members at edge portions of the truncated pyramidal inner magnetic shield. The direction, in which the anhysteretic magnetic permeability of the steel sheet is the higher value, corresponds to the horizontal plane direction of the short side member. In addition, the direction, in which the anhysteretic magnetic permeability of the steel sheet is the higher value, corresponds to as required to the horizontal plane direction of the long side member.

    摘要: A high quality image is achieved by reducing the occurrence of combing noise in a synthesized image having an inserted image of a different frame frequency. A feature amount of a screen produced by an input interlace-scanned video signal is extracted, a film mode on a screen-by-screen basis from the feature amount extracted is detected, the input interlace-scanned video signal to be a synthesized image is decided from a local area in the screen, and the film mode detection is controlled not to output the film mode detection result, based on the decision result.
