Display apparatus, image post-processing apparatus and method for image post-processing of contents

An image post-processing apparatus comprising:

• a storage which stores condition information to distinguish elements to be post-processed from among elements of the contents;
• a group classifier which classifies elements of the contents into at least two groups based on source information of the contents and condition information stored in the storage;
• an image post-processor which post-processes an image corresponding to at least some of the elements of the contents;
• and
• a controller which determines an image post-processing method for each element of one of the at least two classified groups, and controls the image post-processor to post-process the image of each element according to the determined image post-processing method.

A method of displaying contents comprising:

• determining an image post-processing method for elements of the contents based on source information of the contents received from a server and predetermined condition information;
• post-processing the elements of the contents according to the determined image post-processing method;
• and
• rendering the post-processed elements to generate the post-processed contents for a display, wherein at least one element of the contents is post-processed differently from at least one other element of the contents based on the source information.

A method of performing image post-processing comprising:

• classifying elements of contents into at least two groups based on source information of the contents and condition information to distinguish elements to be post-processed from among elements of the contents;
• determining an image post-processing method for each element of at least one of the two groups;
• and
• performing image post-processing of an image corresponding to a respective element of the contents according to the determined image post-processing method.
