    摘要： An inter-frame motion detector detects the presence or absence of motion between frames on the basis of judgment whether or not an inter-frame difference is not more than a set value. A vertical edge continuity detector calculates difference values between an object pixel and pixels above or below the object pixel in an inlaid picture, and detects whether or not there is horizontal continuity of an inter-field vertical edge on the basis of judgment whether or not the signs of the difference values are the same continuously over not less than a predetermined number of pixels, in the horizontal direction, including the object pixel. When it is detected that there is no motion between frames, and it is detected that there is horizontal continuity of the inter-field vertical edge, it is judged that a picture is in a completely still state.

    摘要： A binarizer binarizes a video signal input from an A/D converter and a video signal output from a line memory using an average luminance value provided from a detection window video signal processor as a threshold value, and outputs a binary pattern. A reference pattern generater generates a plurality of reference patterns. An angle detector compares the binary pattern with each of the plurality of reference patterns, and outputs the angle of a matched reference pattern as angle information. An arc shape detector outputs the edge angle information of a picture based on a combination of the angle information of an interpolation scanning line including an object interpolation pixel and the angle information of interpolation scanning lines above and below the interpolation scanning line.

    摘要： A vertical interpolation circuit interpolates an interpolated pixel with pixels located on upper and lower vertical positions, and outputs a vertical interpolated value. An oblique averaging part averages pixels obliquely located with respect to the interpolated pixel on the basis of an oblique edge angle signal, and outputs the result of calculation as an oblique average. An oblique difference absolute value operation part calculates the absolute value of the difference between the values of the pixels obliquely located with respect to the interpolated pixel on the basis of the oblique edge angle signal, and outputs the result of calculation as an oblique difference absolute value. A mixing part outputs the vertical interpolated value, the oblique average or a mixed value thereof as an interpolated pixel value on the basis of the oblique difference absolute value.

    摘要： A video display monitor, such as a plasma monitor, which uses a subfield method which overlaps weighted multiple binary video images in a time base for display. The stable driving of a plasma display panel may be assured and display in the 256 grey-level may be maintained although vertical synchronizing frequency of the input video signal changes. A vertical synchronizing measurement unit measures the vertical synchronizing frequency of the video signal, and a subfield number adjustment unit adjusts the number of subfields in accordance with a measured vertical synchronizing frequency. The stable driving of the plasma display panel and display in grey levels may be assured by selecting a ROM table with an output bit width equivalent to the number of subfields to be output from multiple ROM tables used for converting the number of bits in the input signal.

The supporting bar (7) extends along the article display bar and is positioned above the same. The supporting bar (7) is connected to the engaging piece or the rear end of the article display bar. The urging body (12) is slidably supported by the supporting bar. The at least one article is moved along the article display bar toward the front end of the article display bar by the urging body. The manipulation bar (17) has a rear portion attached to the urging body and extends along the supporting bar.
