Abstract
An image processing apparatus that generates a code stream that encodes image data and includes a dividing unit that divides the image data into at least one rectangular area, a conversion unit that converts data of the rectangular area into conversion data, an ordering unit that adds the priority order to the conversion data, an encoding unit that rearranges the conversion data based on the priority order and encodes the conversion data into the code stream, and a coupling unit that adds a marker in the header part of the conversion data that identifies the priority order of the conversion data in the code stream.
Claims4
An image processing apparatus for generating a code stream that encodes image data, comprising:
- a dividing unit configured to divide the image data into at least one rectangular area;
- a conversion unit configured to convert the at least one rectangular area divided by the dividing unit into conversion data;
- an ordering unit configured to add a priority order to the conversion data;
- an encoding unit configured to rearrange the conversion data based on the priority order to arrange, adjacently in the code stream, the conversion data of the at least one rectangular area, and to encode the conversion data into the code stream;
- and
- a coupling unit configured to add a same marker in a header part of the conversion data for each of a plurality of resolutions of the at least one rectangular area to identify the priority order of the conversion data in the code stream.
A method of image processing that generates a code stream that encodes image data, comprising:
- dividing the image data into at least one rectangular area;
- converting the at least one rectangular area divided in the dividing into conversion data;
- setting a priority order to the conversion data;
- rearranging the conversion data based on the set priority order to arrange, adjacently in the code stream, the conversion data of the at least one rectangular area, and encoding the conversion data into the code stream;
- and
- adding a same marker that identifies the priority order to the header part of the conversion data in the code stream for each of a plurality of resolutions of the at least one rectangular area.
