    摘要: An input image is subjected to transform by a DCT transforming unit 20. A coefficient analyzing unit 30 compares a predetermined coefficient and coefficient data 120, and obtains low-frequency image data 150 of the input image by a high-frequency coefficient masking unit 50 and an inverse DCT unit 60 on the basis of a result of that comparison. A pixel subsampling unit 70 receives this low-frequency image data 150, and generates a subsampled image on the basis of the aforementioned result of comparison. The subsampled image and coefficient information are transmitted to a decoding side. A decoding apparatus decodes an image on the basis of the subsampled image and the coefficient information.

    摘要: An image processing apparatus includes a count unit, a transform unit, a first calculation unit, a second calculation unit, and a binarization unit. The count unit counts the number of pixels of an original binary image. The transform unit transforms the original binary image into a transformed image based on a given transform level. The first calculation unit calculates the number of pixels of the transformed image, based on the given transform level and the number of pixels of the original binary image. The second calculation unit calculates a threshold level based on the number of pixels for each pixel value of the transformed image and the number of pixels of the transformed image. The binarization unit binarizes the transformed image based on the threshold level.
