Title:
IMAGE PROCESSING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/162540
Kind Code:
A1
Abstract:
The present disclosure pertains to an image processing device and method that enable a reduction in encoding efficiency degradation. The present invention involves: setting an upper limit value of the number of bins that are allocated to a processing target subblock by distributing the number of bins to non-zero subblocks; deriving a syntax element value for the processing target subblock by using coefficient data derived from image data so that the number of bins does not exceed the upper limit value; and encoding the derived syntax element value to generate encoded data. The present disclosure is applicable, for example, to an image processing device, an image encoding device, an image decoding device, a transmission device, a reception device, a transmission and reception device, an information processing device, an imaging device, a reproduction device, an electronic device, an image processing method, or an information processing method.
