| 摘要 | An encoding apparatus for encoding progressive image data and interlace image data corresponding to this progressive image data, having a first encoding unit configured to encode picture data composing the interlace image data to generate first encoded data and decoding and recomposing the first encoded data to generate recomposed image data, an up sample processing unit configured to up sample the generated recomposed image data to generate image data having the same resolution as that of the progressive image data, and a second encoding unit configured to encode the picture data composing the progressive image data to generate second encoded data using the generated image data as predictive image data. | ||

| 主权项 | 1. A hardware encoding apparatus for encoding progressive image data and interlace image data corresponding to the progressive image data, the hardware encoding apparatus comprising: a first encoding unit configured to: encode the interlace image data to generate first encoded data; andgenerate recomposed image data based on the interlace image data; an up sample processing unit configured to up sample the recomposed image data generated by the first encoding unit to generate predictive image data having a same resolution as that of the progressive image data, wherein the up sample processing unit includes: a first predictive image generation unit configured to generate the predictive image data of a first kind based on intra-field interpolation; anda second predictive image generation unit configured to generate the predictive image data of a second kind that is different from the predictive image data of the first kind;wherein the up sample processing unit is configured to select one of the first and second predictive image generation units to generate the predictive image data based on flag data; and a second encoding unit configured to encode the progressive image data based on the predictive image data generated by the up sample processing unit to generate second encoded data. | ||
