    • An apparatus for enhancing the visibility of color images includes: a luminance value cumulative distribution calculator that calculates a cumulative distribution function of the number of pixels from a minimum value of luminance values; a baseband signal determining unit that determines baseband signal pixels having luminance values smaller than a threshold level; a luminance compensation value generator that generates luminance compensation values to apply the lower-level luminance compensation values as the pixels have higher-level luminance values, for the pixels having the luminance values larger than the threshold level; a luminance gain generator that determines a luminance gain applied to the luminance compensation values according to a mean luminance values of the input images and the level of the luminance values of the pixels to which the luminance compensation values are applied; and a luminance value enhancing unit that summing the luminance compensation values including the gain with the luminance values.
    • 用于提高彩色图像的可见度的装置包括:亮度累积分布计算器,从亮度值的最小值计算像素数的累积分布函数; 基带信号确定单元,确定具有小于阈值电平的亮度值的基带信号像素; 对于具有大于阈值水平的亮度值的像素,产生用于将作为像素的下位亮度补偿值应用于更高亮度的亮度补偿值的亮度补偿值发生器; 亮度增益发生器,其根据输入图像的平均亮度值和施加了亮度补偿值的像素的亮度值的电平来确定施加到亮度补偿值的亮度增益; 以及亮度值增强单元,其将包括增益的亮度补偿值与亮度值相加。
