The invention provides an apparatus and method for processing an image. An image processing apparatus includes an image processor and an encoder. The image processor enhances an edge of an input image, removes noise from the input image, synthesizes the edge-enhanced image and the noise-removed image, and removes a high frequency from the synthesized image. The encoder pre-encodes a downsized synthesized image, obtains a pre-bit rate of the pre-encoded image, sets a quantization parameter value based on a reference bit rate and the pre-bit rate, and compresses the high-frequency removed imagebased on the quantization parameter value. 提供种用于处理图像的设备和方法。种图像处理设备包括：图像处理器和编码器。图像处理器增强输入图像的边缘，从输入图像去除噪声，将边缘增强的图像和去除噪声的图像进行合成，并从合成的图像去除高频。编码器对缩小的合成的图像预编码，得到预编码的图像的预比特率，基于参考比特率和预比特率设置量化参数值，并基于量化参数值对去除高频的图像进行压缩。
