    Abstract: Exemplary embodiments disclose an image processing method which includes obtaining a binary value by quantizing a value obtained by summing at least one pixel value of an input image and a quantization error value of a neighboring pixel; determining a pixel in which a detail intensity is to be inserted according to the binary value of each pixel; determining the detail intensity to be inserted in the determined pixel; and inserting the determined detail intensity in the determined pixel, wherein the quantization error value of the neighboring pixel is a difference value between an original pixel value of the neighboring pixel and a pixel value quantized with respect to a predetermined constant value.

    Abstract translation: 示例性实施例公开了一种图像处理方法,其包括通过量化通过对输入图像的至少一个像素值和相邻像素的量化误差值求和而获得的值来获得二进制值; 根据每个像素的二进制值确定要插入细节强度的像素; 确定要在所确定的像素中插入的细节强度; 以及将确定的细节强度插入所确定的像素中,其中相邻像素的量化误差值是相邻像素的原始像素值与相对于预定常数值量化的像素值之间的差值。
