    Abstract: Systems and methods for down-scaling are provided. In one example, a method for processing image data includes determining a plurality of output pixel locations using a position value stored by a position register, using the current position value to select a center input pixel from the image data and selecting an index value, selecting a set of input pixels adjacent to the center input pixel, selecting a set of filtering coefficients from a filter coefficient lookup table using the index value, filtering the set of source input pixels to apply a respective one of the set of filtering coefficients to each of the set of source input pixels to determine an output value for the current output pixel at the current position value, and correcting chromatic aberrations in the set of source input pixels.

    Abstract translation: 提供了缩小比例的系统和方法。 在一个示例中，用于处理图像数据的方法包括使用位置寄存器存储的位置值来确定多个输出像素位置，使用当前位置值从图像数据中选择中心输入像素并选择索引值，选择 与中心输入像素相邻的一组输入像素，使用索引值从滤波器系数查找表中选择一组滤波系数，对源输入像素组进行滤波，以将滤波系数集合中的相应一个应用于 所述源输入像素的集合以确定当前位置值处的当前输出像素的输出值，以及校正所述源输入像素集合中的色差。
