Abstract: The present invention provides a movement correction frame count transformation apparatus for carrying out frame count transformation processing on a picture signal. In the apparatus, an input picture signal (S1) of interlaced scanning is converted into a signal (S2) of sequential scanning by an IP conversion unit (1). A movement detecting unit (3) detects movement detection signals (MD1 and MD2). A block unit movement vector searching unit (4) detects a block unit movement vector (BMV) by carrying out block matching processing. A movement vector correcting unit (5) carries out miniblock division processing to generate a movement vector (BV) if a movement correction error is equal to or greater than a threshold value. A pixel unit movement vector generating unit (6) generates a movement vector with a smallest error component between a frame signal of a current frame and a frame signal of an immediately preceding frame as a movement vector of a pixel. An MC interpolation frame signal generating unit (7) generates an interpolation frame in movement correction processing carried out by a median filter in order to produce a signal (S4) of sequential scanning as a result of frame count transformation based on movement correction.

Abstract: An area control section individually sets illumination intensity (light control value) of each backlight cell corresponding to each area of the display screen. A spatial filter corrects the light control values so that spatial distribution of the light control values becomes more moderate between adjoining areas. A black area control section sets the minimum value of the light control value based on a “black area” in the screen. A power control section corrects the light control values so that power consumption of the backlight does not exceed a limit value. A shading control section corrects the light control values to relatively lower brightness in the peripheral part of the screen compared to the central part of the screen. A micro-controller switches the operations of the above light control value correcting sections according to an image display mode selected by the user.

Abstract: A direct type backlight unit used in a liquid crystal display device is provided which can suppress lowering of luminance at an electrode portion of a linear light source. A reflecting plate is formed on a side wall of a box-shaped reflector close to an end of a linear light source. The reflector reflects light beams from the linear light source to be guided toward a liquid crystal panel. The reflecting plate on the side wall has at least two inclined surfaces. The inclined surfaces may have a stepped shape or a convex ridge shape. According to this arrangement, it is possible to reduce or eliminate decrease of the luminance level at ends of an effective display area of a liquid crystal panel.
