Abstract: The present technology relates to an image processing device and an image processing method which allow a deblocking filtering process to apply filtering appropriately. A pixel (p0i) of which the value is 255 (solid line) before a deblocking process changes greatly to 159 (dot line) after a conventional deblocking process. Therefore, a clipping process having a clipping value of 10 is performed in strong filtering, whereby the pixel (p0j) of which the value is 255 (solid line) before the deblocking process becomes 245 (bold line). Thus, a change in the pixel value occurring in the conventional technique can be suppressed as much as possible. This disclosure can be applied to an image processing device, for example.

Abstract: The present technology relates to an encoding device, an encoding method, a decoding device, and a decoding method that make it possible to accurately restore an image. The encoding device generates a filter image by performing, on a decoded image locally decoded, filter processing of applying a prediction equation including a second-order or higher higher-order term and performing a product-sum calculation of predetermined tap coefficients and pixels of the decoded image. Moreover, the encoding device encodes an original image by using the filter image. The decoding device decodes coded data included in an encoded bit stream by using a filter image, to generate a decoded image. Moreover, the decoding device generates the filter image by performing, on the decoded image, filter processing of applying a prediction equation. The present technology can be applied to a case where encoding and decoding of an image are performed.

Abstract: An image processing device and method capable of suppressing block noise.
A β LUT_input calculation unit and a clipping unit calculate β LUT_input that is a value input to an existing β generation unit and an extended β generation unit. When the value of β LUT_input qp from the clipping unit is equal to or less than 51, the existing β generation unit calculates β using the LUT defined in the HEVC method and supplies the calculated β to a filtering determination unit. When the value of β LUT_input qp from the clipping unit is larger than 51, the extended β generation unit calculates extended β and supplies the calculated β to the filtering determination unit. The device can be applied to an image processing device, for example.

Abstract: An imaging device and method for P-phase data compression are provided. The imaging device includes one or more circuits configured to receive a plurality of blocks of P-phase data values from an image sensor. A predictor value is determined for a first input block of the plurality of blocks of P-phase data values. A reconstructed first block of P-phase data values is generated, based on the P-phase data values of the first input block and the determined predictor value. The determined predictor value is then updated for a second block of P-phase data values based on the P-phase data values of the generated reconstructed first block. Compressed P-phase data values that correspond to the received plurality of blocks of P-phase data values are generated, based on the reconstructed first block and at least a reconstructed second block.

Abstract: Implementations generally relate to data-charge phase data compression. In one implementation, a method includes computing prediction values for image data, where the image data is data-charge phase data, where the computing of prediction values is based on inter-block prediction, and where an additional bit-budget is assigned to a first block of the image data. The method also includes computing residual data based on the prediction values. The method also includes quantizing the residual data. The method also includes entropy encoding the quantized residual data. The method also includes refining an inverse quantized residual data based on one or more of the residual data and a number of left-over bit-budget after entropy encoding.
