Latest Patents

Fujimura holds a patent for a video contrast enhancer. This invention enhances luminance contrast by dividing each video frame or field into blocks. It calculates a mean luminance level for each block and selects mapping functions based on these mean luminance levels over a series of frames or fields. The video luminance levels are then mapped according to the selected mapping functions. Additionally, color-saturation contrast is enhanced by modifying the amplitude of the modulated chrominance signal using the histogram equalization method. This method ensures that the color phase remains unaffected while enhancing the visual quality of the video.
