It is possible to encode an I picture matched with a predetermined condition by using parameter information. In step S1, if the picture type is judged to be I picture, in step S2 it is judged whether the phases of macro blocks in the previous and the current encoding are matched. If the phases are matched, in step S3, it is judged whether the amount of codes generated in picture unit during decoding <= target code amount x alpha is satisfied. If the condition is satisfied, then in step S4, it is judged whether the image frame of the previous encoding is identical to that of the current encoding. If the image frames are not identical, the picture type, the motion vector, and quantization value information contained in the parameter information are re-used. If the image frames are identical, the stream data inputted to the decoding section is output. If the aforementioned condition is not satisfied, the parameter is not re-used. The present invention can be applied to an encoding section, an encoding device, an information recording device, an information reproduction device, or a transcoder.
