An image processing apparatus includes: a memory configured to store one or more instructions; and at least one processor configured to execute one or more instructions to optimize an estimated pixel value and an estimated gradient value for each pixel of an original image corresponding to the first image based on the first image and a probability model, an estimated original image is obtained based on the optimized estimated pixel value of each pixel of the original image, a decontoured map is obtained based on the optimized estimated pixel value and the estimated gradient value of each pixel of the original image, and a second image is generated by combining the first image with the estimated original image based on the decontoured map. 一种图像处理设备，包括：存储器，被配置为存储一个或更多个指令；以及至少一个处理器，被配置为执行一个或更多个指令以进行以下操作：基于第一图像和概率模型，优化与第一图像对应的原始图像的每个像素的估计像素值和估计梯度值，基于原始图像的每个像素的优化的估计像素值获得估计原始图像，基于原始图像的每个像素的优化的估计像素值和估计梯度值获得去轮廓图，以及通过基于去轮廓图将第一图像与估计原始图像组合来生成第二图像。
