摘要： A frequency of each gradation in an image for the left eye histogram is compared with a frequency of each gradation in an image for the right eye histogram. An integration histogram is generated using at least a larger one of the frequency of each gradation in the image for the left eye histogram and the frequency of each gradation in the image for the right eye histogram. A gradation correction parameter is set based on the generated integration histogram. The gradations of the image for the left eye and the image for the right eye are corrected using the gradation correction parameter.

摘要： Denoting a maximum value of three primary color signals RGB by Max, a minimum value by Min, and coefficients by a and b, the color temperature of only colors close to achromatic colors is changed by adding (a*Min−b*Max) to the signal B. Denoting a luminance level by Y, and coefficients by c and d, the color temperature of only colors close to achromatic colors is changed by adding (c*Y−d*(Max−Min)) to the signal B. Color temperature of only colors close to achromatic colors is changed by multiplying the signal B by a coefficient based on a value of (Man−Min)/Max, which represents saturation.
摘要翻译：通过将最大值三分之一以RGB表示为最大值，最小值为Min，系数为a和b，通过将（a * Min-b * Max）加到（a * Min-b * Max）中来改变接近无彩色的仅有颜色的色温信号B.通过将亮度等级设为Y，通过c和d表示系数，通过向信号B添加（c * Yd *（Max-Min））来改变接近无彩色的仅有颜色的色温。色温通过将信号B乘以基于表示饱和度的（Man-Min）/ Max的值的系数来改变仅接近消色差的颜色。

摘要： This invention can suppress overshoot/undershoot, and can maintain the improvement effect of the leading edge of an edge portion. For this purpose, a second derivative signal generator (1) generates a second derivative signal (s5) on the basis of time-serially input three successive pixels. A second derivative signal suppression unit (2) generates a signal (s8) obtained by suppressing the second derivative signal, and a signal (s9) indicating the sign of the second derivative signal. The absolute values of the differences between the pixel of interest, and its neighboring pixels are computed, and a smaller one of the absolute values is selected as a signal (s14) by a minimum value selection circuit (18). By multiplying the obtained signals (s8, s9, s14) by a multiplier (19), an edge-emphasizing signal (s15) is generated. The edge-emphasizing signal (s15) is added to the signal of the pixel of interest by an adder (20), thus obtaining an edge-emphasized signal s16.
