APPARATUS AND METHOD FOR PROCESSING 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...

Beschreibung
Zusammenfassung:	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 image based on the quantization parameter value.
