Latest Patents

Nagashima holds a patent for a "Backlight luminance control apparatus and video display apparatus." This invention involves a video display apparatus where the backlight illuminating a liquid crystal panel is segmented into multiple areas. A frequency distribution processing unit calculates the dark pixel amount based on the frequency distribution of the gradation values of pixels in a video image. The backlight control unit then determines a lower limit of luminance for each area, which increases as the dark pixel amount decreases. This technology allows for individual adjustment of luminance in each area according to the gradation values, reducing luminance blur and enhancing image clarity.
