    • An image processing apparatus includes a parameter input unit, a tap extraction unit, a predictive coefficient calculation unit, a predictive coefficient calculation unit, and a pixel value operation unit. The parameter input unit receives a parameter including an output phase, the size of an output pixel, and a variable used for a condensing model. The tap extraction unit extracts a tap including a pixel value of a focus pixel which corresponds to the output phase and pixel values of neighboring pixels of the focus pixel. The predictive coefficient calculation unit calculates a predictive coefficient to be multiplied by each of the elements of the tap. The pixel value operation unit calculates a value of the output pixel by performing a product-sum operation of the calculated predictive coefficient and each of the elements of the tap.
    • 图像处理装置包括参数输入单元,抽头提取单元,预测系数计算单元,预测系数计算单元和像素值操作单元。 参数输入单元接收包括输出相位,输出像素的大小和用于冷凝模型的变量的参数。 抽头提取单元提取包括与输出相位对应的焦点像素的像素值和焦点像素的相邻像素的像素值的抽头。 预测系数计算单元计算要与抽头的每个元素相乘的预测系数。 像素值操作单元通过执行计算出的预测系数和抽头的每个元素的乘积和运算来计算输出像素的值。
