摘要： PROBLEM TO BE SOLVED: To display impressive TV images on a television set without using a lighting unit while reducing power. SOLUTION: A liquid crystal display device is installed in a television set 1, and a liquid crystal display panel serves as a display screen 2 of the television set. A part of backlight of the liquid crystal display device is guided to the outside of the television set 1, and is used as background luminance of the television set. The light from backlight used as the background luminance is emitted to the rear of the television set 1. Since light quantity of the backlight is constant, the background luminance is adjusted by controlling the area of open/close windows 61. The area of the open/close windows 61 is automatically adjusted by a linear motor or the like in response to the brightness of the display screen, thus obtaining background luminance according to the images.

摘要： PROBLEM TO BE SOLVED: To enable frame rate conversion with a higher degree of accuracy by means of a simpler circuitry. SOLUTION: A searching area SA +1 , a searching area SA -1 for defining, as a central pixel, a pixel rightly opposite to the interpolation position P 0 of an interpolation frame pixel are set using a present frame and the last frame of image signals. Pixel groups in each searching area SA -1 , SA +1 having a point-symmetry relationship with respect to the interpolation position P 0 are made to be paired pixel and differences between luminance values of each pixel of the paired pixel are determined for all the paired pixel. Then, the paired pixel with the smallest absolute value of the difference is selected as a interpolation paired pixel from among these paired pixels or a plurality of the pixels is selected as a provisional interpolation paired pixel in the order of starting with the paired pixel of the smaller absolute value of the difference. Among the provisional interpolation paired pixel, one paired pixel for satisfying an edge condition or the like is made as the interpolation paired pixel to produce the interpolation frame from the present frame and the last frame together with interpolation pixel vectors of these interpolation paired pixel.
