摘要:
A color changing device which is used to correct the variation of the hue without narrowing the color reproduction range, has a small circuit scale, and does not need many memory resources. A primary area sensor (10) judges to what area out of six areas classified according to the magnitude relationship of the RGB the input RGB values belong and outputs the minimum RGB values. A boundary coefficient table (11) outputs a coefficient determining the boundary to bisect the six primary areas according to the parameter indicating the primary area. The coefficient and the RGB values are multiplied and then added. A comparator (12) compares the sum with the RGB minimum values outputted from the primary area sensor (10), and the result is inputted into a matrix coefficient table (13). The matrix coefficient table (13) outputs the coefficient of a matrix operation to convert the RGB value to output R', G', B' values corresponding to the area to which the input RGB values belong according to the parameter indicating the primary area and the result of the comparison by the comparator (12).

用于校正色相的变化而不使颜色再现范围变窄的变色装置具有小的电路规模,并且不需要许多存储器资源。 主区域传感器(10)根据输入RGB值所属的RGB的大小关系来判断六个区域中的哪个区域,并输出最小的RGB值。 边界系数表(11)根据指示主区域的参数,输出确定边界的系数,以平分六个主要区域。 系数和RGB值相乘,然后相加。 比较器(12)将和与主区域传感器(10)输出的RGB最小值进行比较,并将结果输入矩阵系数表(13)。 矩阵系数表(13)根据表示主区域的参数输出矩阵运算的系数,将RGB值转换为与输入RGB值所属的区域对应的输出R',G',B'值, 比较器(12)的比较结果。
