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： An optical disc drive includes a light source, a lens, a focusing section, a spherical aberration corrector, a focus signal generator, a gain calculator and a processor. The focusing section forms a beam spot in a focusing state on the information storage layer of an optical disc by controlling the position of the lens. The spherical aberration corrector changes a spherical aberration with the beam spot in a focusing state according to a drive value of a driving signal supplied to the spherical aberration corrector. The focus signal generator generates a focus signal representing the focusing state of the beam spot. The gain calculator calculates a loop gain of a focus control system in response to the focus signal. The processor determines the drive value for the spherical aberration corrector by the loop gain.

摘要： An optical disk apparatus includes an optical detector which has light receiving areas divided nearly concentrically with an optical beam and outputs a signal corresponding to the amount of the reflected light from an optical disk. A surface vicinity detecting section adds up signals from all the light-receiving areas of the optical detector and outputs a detection signal. The detection signal continuously varies so as to have one maximum level while a beam spot of the optical beam moves from the surface of the information medium to the information plane. An information plane detecting section judges that the focus or the beam spot of the optical beam comes closer to the information plane of the optical disk by detecting the gradient of the detection signal. An approach of a condensing lens and the optical disk is judged based on the judgment results, and thus a collision of the condensing lens and the optical disk can be prevented.

摘要： The present technology relates to an encoding device and an encoding method, and a decoding device and a decoding method that are capable of reducing the calculation amount of orthogonal transform processing or inverse orthogonal transform processing. A DWT unit (91) performs a DWT of which the calculation amount is smaller than that of a KLT for residual information. KLT units (92-0 to 92-8) perform separable-type KLTs for a low-frequency component of the residual information that is acquired as a result of the DWT using bases of KLTs of the corresponding intra prediction modes. A coefficient acquired as a result of the KLT and a high-frequency component of the residual information that is acquired as a result of the DWT are losslessly encoded. The present technology can be applied to, for example, an image encoding device.

摘要： The present invention relates to an image processing device and method whereby deterioration of effects of filter processing due to local control of filter processing when encoding or decoding can be suppressed. A boundary control flag generating unit 132 of a control information generating unit 112 generates boundary control flags based on system specification information which a system specification managing unit 141 manages. A control unit 171 of an adaptive filter processing unit 113 determines a processing method for filter processing to be performed as to pixels nearby a slice boundary following the value of the boundary control flag. For example, selection is made to perform filter processing straddling slices or to perform filter processing closed at the present slice. The present invention can be applied to an image processing device, for example.

摘要： The present invention relates to an image processing device, an image processing method, and a program that can reduce processing loads and delays while suppressing decreases in inter prediction precision when motion compensation operations with fractional precision are performed in inter predictions. When a pixel of a predicted image in an inter prediction has a fractional pixel position that is not a ½ pixel position in the horizontal direction and the vertical direction in a reference image, a reference image read unit 41 reads predetermined reference pixels including reference pixels aligned in two oblique directions perpendicular to each other. A FIR filter 42 calculates a pixel in a fractional position in the reference image as the pixel of the predicted image, by using the read predetermined reference pixels. The present invention can be applied to encoding devices that perform compression encoding by H.264/AVC, for example.
