摘要： According to the present invention, an image coding apparatus (103) that encodes quantized coefficients corresponding to an image signal as target data to be processed is provided with a run-length encoding unit (RLE2) that assigns variable length codes to the quantized coefficients using code tables. The run-length encoding unit (RLE2) forms a second code table by optimizing a first code table to the target data to be processed, and selects one of the first and the second code tables as a code table that is to be employed for the assignment of the variable length codes in accordance with a quantization parameter (QP) or a variable length coding selection signal (VlcSel), whereby redundancy of information included in the target data to be processed can be effectively eliminated, and the compression ratio for the image signal or the like can be further increased.

摘要： In a picture coding method for generating a coded signal corresponding to each picture by coding a plurality of coded signals, a switching picture which is capable of switching a plurality of coded signals and subsequent pictures of the switching picture can refer to only a group of pictures of the same time in the coded signals. More specifically, the case where picture numbers of an adjacent picture of an S picture and the S picture are not continuous is not considered as an error.

摘要： A moving picture coding apparatus (10a) according to the present invention includes a level analyzer (100a) that decides the maximum number of intra frame pixels which can be coded (Nfpx) and the maximum number of storage pixels which can be stored in a picture memory of a decoding apparatus (Nspx) on the basis of a level identifier (Lst) indicating a coding level that is designated by the user, thereby judging whether coding of an input image is possible or not and calculating the maximum number of reference pictures (Nrpn) as the number of reference candidate pictures which can be referred to at inter picture prediction coding, on the basis of the maximum number of intra frame pixels (Nfpx) and the input image size (the number of vertical pixels (Nhpx) and the number of horizontal pixels (Nwpx)). A decoding apparatus to which a bit stream from the moving picture coding apparatus (10a) is supplied can always decode the bit stream satisfactorily, and perform inter picture prediction decoding corresponding to the inter picture prediction coding on the coding end. Consequently, memory areas of a coding apparatus and a decoding apparatus that are adapted to a coding method in which there is no restraint on the capacity of the memory area can be designed.
