    • An image processing apparatus includes a multiplying unit configured to multiply an original image by a coefficient α used for α blending, thereby generating an α-fold original image, a quantizing unit configured to quantize the α-fold original image and output a quantized α-fold original image obtained through the quantization, a gradation converting unit configured to perform gradation conversion on the α-fold original image by performing a dithering process, thereby generating a gradation-converted α-fold original image, and a difference calculating unit configured to calculate a difference between the gradation-converted α-fold original image and the quantized α-fold original image, thereby obtaining a high-frequency component in the gradation-converted α-fold original image, the high-frequency component being added to a quantized composite image, which is generated by quantizing a composite image obtained through α blending with a quantized image generated by quantizing the original image.
    • 一种图像处理装置,包括:乘法单元,被配置为将原始图像乘以用于α混合的系数α,从而生成α倍原始图像;量化单元,被配置为量化所述α倍原始图像,并输出量化的α- 灰度转换单元,被配置为通过执行抖动处理对所述α折叠原始图像执行灰度转换,从而生成灰度转换的α折叠原始图像,以及差分计算单元,被配置为计算 灰度转换的α倍原始图像和量化的α折叠原始图像之间的差异,从而获得灰度转换的α倍原始图像中的高频分量,将高频分量添加到量化复合物 图像,其通过量化通过α混合获得的合成图像与通过量化生成的量化图像而生成 原始图像。
