Abstract: An upper limit value of the number of bins allocated to a processing target subblock by distributing the number of bins among nonzero subblocks is set, a syntax element value regarding the processing target subblock is derived by using coefficient data derived from image data so that the number of bins does not exceed the upper limit value, and the syntax element value derived is encoded and coded data is generated. The present disclosure can be applied, for example, to an image processing apparatus, an image encode apparatus, an image decode apparatus, a transmitting apparatus, a receiving apparatus, a transmitting/receiving apparatus, an information processing apparatus, an imaging apparatus, a reproducing apparatus, an electronic device, an image processing method, an information processing method, and the like.

Abstract: The present disclosure relates to an image processing apparatus and method capable of suppressing a reduction in encoding efficiency.
An upper limit value of the number of bins allocated to a processing target subblock by distributing the number of bins among nonzero subblocks is set, a syntax element value regarding the processing target subblock is derived by using coefficient data derived from image data so that the number of bins does not exceed the upper limit value, and the syntax element value derived is encoded and coded data is generated. The present disclosure can be applied, for example, to an image processing apparatus, an image encode apparatus, an image decode apparatus, a transmitting apparatus, a receiving apparatus, a transmitting/receiving apparatus, an information processing apparatus, an imaging apparatus, a reproducing apparatus, an electronic device, an image processing method, an information processing method, and the like.
