摘要： PROBLEM TO BE SOLVED: To provide an information processing apparatus, an information processing method and its program, for carrying out the compression encoding of a plurality of focus face images whose focus positions are different with a high compressibility, and for decoding the focus face images in a short processing time. SOLUTION: From among MB5 of a plurality of focus face images I(z), a representative best-focused MB6 is selected so that an all-in-focus image I all_focused can be generated. For every representative MB6 of the all-in-focus images I all_focused , a blur compensation filter PSF (Point Spread Function) corresponding to the position coordinate z of the focus face image I(z) is superimposed, and a blur compensation predicted image 9 is generated with high accuracy. A difference image 10 between the blur compensation predicted image 9 and the focus face image I(z) is generated so that the compression encoding of the focus face image I(z) can be carried out with a high compressibility. Also, the blur compensation predicated image 9 and the difference image 10 are added so that the arbitrary focus face image I(z) can be decoded in a short processing time.

摘要： PROBLEM TO BE SOLVED: To substantially equalize the quality of an obtained decoded image to the quality of an input image. SOLUTION: An encoder so generates the difference-value data of image data from its input data, and so processes this data a discrete-cosine-transform-wise at an arbitrary output-bit accuracy as to generate the discrete-cosine-transform factors of the input image data. Then, the discrete-cosine-transform factors are quantized by using an expanded quantizing scale, based on at least one of the output-bit accuracy and an input-bit accuracy of the input image data. Thereafter, the obtained quantized factors are so compression-coded by using a variable-length coding table as to be able to perform the compression-coding while preventing the degrading of the image quality. Also, the compression-coded quantized factors are compression-decoded by using the variable-length coding table. Then, the obtained quantized factors are so processed inverse-quantization-wise by using the expanded quantization scale, based on at least one of the input-bit accuracy of the input image data and the output-bit accuracy of the discrete-cosine-transform factors as to be able to perform the decoding while preventing the degrading of the image quality.

摘要： PROBLEM TO BE SOLVED: To provide a method using a non-initialized buffer that can be simplified.
SOLUTION: A timing scenario is explained using an example. In the example, an encoder generates again a random access point after a fifth picture. In the example, in order to achieve picture quality as high as possible (frequently in such a scenario), a first picture after the random access point should be a relatively large picture (for performing intra-encoding). By using such a modification model, since there is no limitation where a buffer is made empty at the point, a relatively large data amount can be allocated to the first picture after the random access point, in place of the fifth picture.

摘要翻译：要解决的问题：提供一种使用可以简化的非初始化缓冲器的方法。
解决方案：使用示例说明时序情景。在该示例中，编码器在第五图像之后再次生成随机接入点。在该示例中，为了尽可能高地实现图像质量（频繁地在这种情况下），随机接入点之后的第一图像应该是相对较大的图像（用于执行帧内编码）。通过使用这样的修改模型，由于在该点处没有限制使缓冲器为空，所以可以在随机接入点之后的第一图像中分配相对大的数据量来代替第五图像。版权所有（C）2009，JPO＆INPIT
