Information processing device, information processing method, and program

An information processing method comprising:

• calculating, for an image divided into a plurality of blocks, a depth value for determining presence or absence of processing of a deblocking filter and determining strength of the deblocking filter based on a division state of respective blocks adjacent to a block boundary;
• determining whether or not to cause the deblocking filter to operate on the block boundary based on the depth value;
• setting the strength of the deblocking filter to operate on the block boundary based on the depth value;
• and
• calculating a division depth value of the block boundary based on a position of the block boundary in the image.

A non-transitory computer-readable medium having stored thereon computer-executable instructions that, when executed by a computer processor of an information processing device, cause the information processing device to function as:

• a depth value calculation unit configured to calculate, for an image divided into a plurality of blocks, a depth value to determine presence or absence of processing of a deblocking filter and determine strength of the deblocking filter based on a division state of respective blocks adjacent to a block boundary;
• a filter processing execution determination unit configured to determine whether or not to cause the deblocking filter to operate on the block boundary based on the depth value;
• and
• a filter strength setting unit that sets the strength of the deblocking filter to operate on the block boundary based on the depth value, wherein the depth value calculation unit is further configured to calculate a division depth value of the block boundary based on a position of the block boundary in the image.
