INFORMATION PROCESSING DEVICE AND METHOD

The present disclosure relates to an information processing device and a method enabling suppression of reduction in subjective image quality while suppressing reduction in coding efficiency. An influence on a subjective image quality of a decoded image by applying ZeroOut to quantization coefficients corresponding to an image when coding the image is estimated, and division of a block is controlled on the basis of the estimated influence when setting a size of the block serving as a unit of processing in the coding of the image. The present disclosure may be applied to, for example, an information processing device, a coding device, an electronic device, an information processing method, a program or the like.
