In prediction, one of a first mode for deriving, using pixels in an image including a target block, predicted pixels in the target block, a second mode for deriving the predicted pixels in the target block using pixels in an image different from the image including the target block, a third mode for generating the predicted pixels in the target block using both the pixels in the image including the target block and pixels in the different image can be used. If the third mode is used in at least one of the first and second blocks, the intensity of deblocking filter to be performed for the boundary between the first and second blocks is set to the same intensity as in a case in which the first mode is used in at least one of the first and second blocks.

Image encoding apparatus, image encoding method, image decoding apparatus, image decoding method, and non-transitory computer-readable storage medium

An image is divided into rectangular regions each including at least one block row, and the image is divided into rectangular slices or slices to be processed in raster order. In a case where the image is divided into the rectangular slices, based on first information for specifying a rectangular region to be processed first and second information for specifying a rectangular region to be processed last, the rectangular regions in the rectangular slice is specified. Based on the number of blocks in a vertical direction in each of the specified rectangular regions, the number of pieces of information for specifying a start position of coded data of the block row in the rectangular slice is specified. A bitstream in which at least the pieces of information, the first and second information, and the coded data are multiplexed is generated.

Image encoding apparatus, image decoding apparatus, image encoding method, image decoding method, and non-transitory computer-readable storage medium

An image is divided into a plurality of tiles and the tile is divided into rectangular regions each including at least one block row formed from a plurality of blocks each having a size smaller than the tile. If each slice in the image includes only one rectangular region, based on the number of blocks in a vertical direction in the rectangular region, the number of pieces of information for specifying a start position of coded data of the block row in the slice is specified. A bitstream in which at least the pieces of information, whose number is as many as the specified number, information representing that each slice in the image is formed by only one rectangular region, and the coded data of the block row are multiplexed is generated.

An imaging apparatus includes a processor executing instructions which, when executed by the processor, cause the imaging apparatus to detect an object included in an image captured by an imaging unit, generate meta data conforming to annotated regions supplemental enhancement information (ARSEI) including positional information for the object detected from the image, and transmit transmission data including coded data generated by encoding the image and the meta data related to the image to an external apparatus, wherein, in a case where a variation of a parameter of a first object detected from a second image captured after a first image with respect to the parameter of the first object detected from the first image is less than a threshold value, meta data not including positional information for the first object in the second image is generated as meta data related to the second image.

Imaging apparatus, information processing method, and storage medium

An image coding apparatus configured to divide an image into one or more slices each including a plurality of blocks and to code each slice on a block-by-block basis includes a first coding unit configured to code blocks included in a first portion of the slice, and a second coding unit configured to code blocks included in a second portion of the slice, wherein, when the second coding unit codes an initial block in the second portion, the second coding unit codes the initial included in the second portion by referring to a first quantization parameter provided to the slice as an initial value and referred to by the first coding unit when the first coding units codes the initial block in the first portion.
