    摘要: An image processing device carries out processing in a processing unit of 3-blocks. Data of 192(=64×3)-pixels is required in the processing of 3-blocks. This is an amount of data corresponding to 16-cells. When 3-blocks and 16-cells are arranged along an scanning direction of an image, both ends of them in the scanning direction are aligned.

    摘要: A first look-up table (10) outputs a result of dividing a horizontal component of a pixel address in the block by number of pixels in a horizontal component of the cell. A second look-up table (12) outputs a result of dividing a vertical component of a pixel address in the block by number of pixels in a vertical component of the cell. A third look-up table (14) outputs a residue as a result of dividing a horizontal component of a pixel address in the block by number of pixels in a horizontal component of the cell. A fourth look-up table (16) outputs a residue as a result of dividing a vertical component of a pixel address in the block by number of pixels in a vertical component of the cell. The output values of the first and second look-up tables (10,12) are addresses of the cell for burst access to the memory. The output values of the third and fourth look-up tables (14,16) are used as pixel addresses in the cell.

    摘要: An object of the present invention is to provide a binary arithmetic coding device that allows real-time processing with a higher image quality. At a timing at which a ternary data string for a target bit is outputted, an updated coding range width and an updated range width of less probability are outputted. For that reason, while a binary conversion unit (32) and an f value retention processor (33) convert the ternary data string into a binary data string to output a coded bit, a binary arithmetic re-normalization unit (31) is allowed to perform a processing of binary arithmetic coding for the next bit.
