Abstract: PURPOSE:To reduce the number of quantizing errors and shorten the operating time of a picture compressing device, by providing a preprocessing means which pre-processes original- picture data and a rearranging section which rearranges an orthogonally transformed output in blocks of the same frequency component each to the device. CONSTITUTION:Firstly, an original picture is divided into plural blocks under the control the an address control section 3 and the blocks are sent to an arithmetic section 4. The differential output obtained at the arithmetic section is sent to a picture compressing means 7 as a pre-processed output and further sent to a rearranging section 17 after the pre-processed output is orthogonally transformed at every prescribed block by means of a 1st orthogonally transforming section 13. At the rearranging section 17, the orthogonally transformed blocks are rearranging in blocks of the same frequency component each under the control of an address controller 18. The rearranged blocks are fetched by a block selecting section 21 and divided into two groups, with the one group being composed of blocks on which orthogonal transformation is required and the other group being composed of those on which orthogonal transformation is not required. The blocks on which orthogonal transformation is required are subjected to one-dimension orthogonal transformation at a 2nd orthogonally transforming section 20. Therefore, operating time can be shortened sharply and number of quantizing errors can be reduced.
