Abstract: An image processing apparatus executes quantization of a plurality of types of coefficients for respective transform processing blocks for residual data that indicates a difference between original image data and predicted image data calculated by a computing part 12. For example, a transform coefficient produced by an orthogonal-transforming part 14 is quantized by a quantizing part 15 to produce transform quantized data, and the residual data is quantized by a quantizing part 16 by using transform skipping that skips orthogonal transform to produce transform-skipping quantized data. An entropy coding part 28 codes the transform quantized data and the transform-skipping quantized data to produce a coded stream. Degradation in image quality of a decoded image generated by using the transform skipping can be suppressed using the decoding result of the transform coefficient quantized data.

Abstract: A workpiece holding method for a workpiece having a bowl-shaped warp includes a mounting step of mounting the workpiece on a holding unit having a holding surface, a suction hole opening to the holding surface, and a suction passage for making selective communication between the suction hole and a vacuum source for producing a suction force, the workpiece being mounted on the holding surface of the holding unit, a liquid supplying step of supplying a liquid to the workpiece held on the holding surface so that the liquid flows into a gap defined between the holding surface and the workpiece to fill the gap, and a suction step of bringing the suction hole into communication with the vacuum source to suck the liquid and the workpiece and thereby hold the workpiece through the liquid on the holding surface under suction, after performing the liquid supplying step.

Abstract: A filter processing section 352 performs a filter process for applying an offset to pixels of a decoded image. A filter controller 351 inhibits the offset from being applied to an edge portion depending on occurrence of a transform unit in a transformation skip mode in which orthogonal transformation is not performed on a predicted residual. Furthermore, the filter controller 351 determines whether an offset for gradation adjustment using the decoded image is to be applied in the filter processing section 352 or not, and sets an offset in case the offset is to be applied. It is possible to make less conspicuous in the boundary between a transform unit where orthogonal transformation is performed by the offset for gradation adjustment and the transform unit where orthogonal transformation is skipped. The image quality of the decoded image is restrained from being lowered.
