摘要： An encoded bit stream is processed by a lossless decoding unit (52), an inverse quantization unit (53), and an inverse orthogonal transform unit (54) in this order, to obtain orthogonally transformed coefficient data and encoding parameter information. The inverse orthogonal transform unit (54) performs an inverse orthogonal transform on the coefficient data by using bases that are set beforehand in accordance with the locations of transform blocks in a macroblock indicated by the encoding parameter information. In this manner, prediction error data is obtained. An intra prediction unit (62) generates predicted image data. An addition unit (55) adds the predicted image data to the prediction error data, to decode image data. By using bases that are set in accordance with the locations of transform blocks, an optimum inverse orthogonal transform can be performed, and encoding efficiency can be increased.

摘要： The present invention relates to an image processing apparatus and method and a program which can reduce the bit amount included in a stream and a used region of a memory. In an image encoding apparatus 51, when an object slice is a B slice, the tap number of a variable interpolation filter (AIF) is determined, for example, as four taps. Therefore, even in the case where bidirectional prediction of a 4×4 size is carried out, only it is necessary to read in, in addition to pixels of 4×4 blank squares obtained after the interpolation process, pixels of squares to which slanting lines are applied, that is, 98=2×49 pixels from the forward direction and the succeeding direction from a frame memory. In other words, in comparison with a conventional case, 32 pixels indicated by dark squares are not required for the interpolation process any more. The present invention can be applied, for example, to an image encoding apparatus for encoding, for example, on the basis of the H.264/AVC method.

摘要： The optical disc apparatus according to the present invention includes a tilt detecting means; a coma aberration correcting means; and a spherical aberration correcting means. Based on the result of a tilt detection, the amount of the correction performed by the coma aberration correcting means is determined so that the amount of correction is constant for the whole circumference of an optical disc, and then a spherical aberration is corrected by the spherical aberration correcting means. Thus, it is possible to correct the spherical aberration that has occurred due to the coma aberration correcting means, while the tilt margin is secured, thereby improving the reliability of reproduction and recording by the optical disc apparatus. Further, the optical disc apparatus according to the present invention is configured, in the case where a thermal shock tilt has occurred during the activation of the apparatus, to wait until the thermal shock tilt has settled. Thus, it is possible to perform the activation while the influence of the thermal shock tilt is avoided, thereby improving the reliability of the recording and reproduction operations by the optical disc apparatus.

摘要： A polarized image acquisition section shoots a subject through a polarizing element operable to set principal axes of which directions are different from each other. An incident plane specifying section specifies an incident plane of each pixel, and an incident angle computation section computes an incident angle of each pixel. A classifying section clusters pixels similar to each other in both incident plane and incident angle. A reflection component separation section performs reflection component separation on each clustered pixel set on the assumption of probabilistic independence between the diffuse reflection component and the specular reflection component.
