摘要： A system for coding an I-picture that satisfies a predetermined condition using parameter information. When it is determined that a picture type is the I-picture, it is determined whether or not the phase of a macro block in previous coding agrees with that of the macro block of present coding. When the phases of the macro blocks agree with each other, it is determined whether or not amount of generated code in a unit of picture in decoding≦target amount of code×α is satisfied. When the condition is satisfied, it is determined whether or not an image frame of previous coding is the same as that of previous coding. When the image frames are not the same, the information of a picture type, motion vector, and a quantized value included in the parameter information is reused, whereas when the image frames are the same, the stream data input to a decoder is output. When the above condition is not satisfied, the parameters are not reused. The present invention can be applied to a coder, a coding apparatus, an information recording apparatus, an information reproducing apparatus, or a transcoder.

摘要： To generate coded data including additional coding information, non-compressed image data is first supplied. The number of predetermined units (i.e.: frame) of the non-compressed image data is counted. Coding is performed on the supplied non-compressed image data. Information for specifying a coding device stored in a memory and the unit count number are obtained and are combined to generate additional coding information. The additional coding information is added to coded data and the resulting data is then output. It is predetermined whether the supply of the non-compressed image data is completed. If not, the number of frames is counted and the following steps are repeated. If the supply of the non-compressed image data is completed, the process is completed.

摘要： A reusable quantization value Qref included in history information or parameter information is obtained in step S21. In step S22, it is judged whether or not the quantization value Qref obtained in step S21 is smaller than a predetermined minimum quantization value Qmin. If it has been judged that the quantization value Qref is smaller than the predetermined minimum quantization value Qmin, the process proceeds to step S23, where the quantization value Q is set at Qmin, and then the process is completed. If it has been judged that the quantization value Qref is not smaller than the predetermined minimum quantization value Qmin, the process proceeds to step S24, where the quantization value Qref is reused and is set as the quantization value Q, and then the process is completed. The present invention can be applied to an SDTI CP-ASI converter or a long GOP encoder.

摘要： The present invention can suppress the decline in video quality during encoding. The present invention generates, for each of the nine intra image prediction modes preset according to the AVC standard, a difference image data item containing a difference value from pixels surrounding a process-target pixel. Then, an encoding device (10) ranks the intra image prediction modes depending on the sum of absolute difference (SAD), which is the sum of differences that is based on the sum of absolute values of each process-target pixel of the difference image data item and a preference order of offset[n] preset for the intra image prediction mode.

The present invention multiplies a decoding rescaling factor (RFr) possibly used in the decoding process by only a transformation matrix (D), which is scale change, to calculate a rescaling factor (RF), which is a plurality of division factors, and then calculates, for each detection unit, the sum (ΣY) of evaluation values (Y) based on a residue (r) obtained as a result of dividing an element of a DCT coefficient by a plurality of rescaling factors (RF). Moreover, the present invention compares correlations of the sum (ΣY) of the evaluation values (Y) with a plurality of rescaling factors (RF), and detects, based on the rescaling factor (RF) whose sum (ΣY) of the evaluation values (Y) is a minimum value, a quantization factor used in the previous process of encoding the input image data.

摘要： The present invention can code an I-picture that satisfies a predetermined condition using parameter information. When it is determined at step S1 that a picture type is the I-picture, it is determined at step S2 whether or not the phase of a macro block in previous coding agrees with that of the macro block of present coding. When the phases of the macro blocks agree with each other, it is determined at step S3 whether or not amount of generated code in a unit of picture in decoding≦target amount of code×α is satisfied. When the condition is satisfied, it is determined at step S4 whether or not an image frame of previous coding is the same as that of previous coding. When the image frames are not the same, the information of a picture type, motion vector, and a quantized value included in the parameter information is reused, whereas when the image frames are the same, the stream data input to a decoder is output. When the above condition is not satisfied, the parameters are not reused. The present invention can be applied to a coder, a coding apparatus, an information recording apparatus, an information reproducing apparatus, or a transcoder.
