<p>An image compression apparatus and method for producing and using an assistant image for deblocking processing. The image compression apparatus has an assistant image generation unit for generating an assistant image by using an original image, an image compression part for compressing the generated original image and assistant image, and a deblocking processing part for applying the deblocking processing to the compressed original image by using the compressed assistant image. Since the deblocking processing is carried out in the image compression process, the image compression apparatus can prevent the blocking artifacts even in cases where a consumer's product for decompressing and reproducing the compressed images is not a deblocking means. Further, the existing general image compression encoder can be used without change, and the reduced computation amounts necessary for the deblocking processing can result in reducing the processing load, increasing a processing rate, and reducing power consumption of the processor. <IMAGE></p> |
