Code processing device, code processing method, program, and recording medium
First Claim
1. A code processing device which generates, from original codes having sets of partial codes with quality attributes and resolution attributes, output codes having a quality according to a specified quality value, the code processing device comprising:
- a rank assignment unit to assign ranks to the sets of partial codes respectively, wherein, when the sets of partial codes have different quality levels, a high rank is assigned to a set of partial codes having a low quality level, and when the sets of partial codes have a same quality level and different resolution levels, a high rank is assigned to a set of partial codes having a low resolution level;
a partial code selecting unit to select sets of partial codes from among the original codes, which have the quality according to the specified quality value and are included in the output codes, in order of the ranks assigned by the rank assignment unit; and
a code forming unit to form the output codes in which the sets of partial codes selected by the partial code selecting unit are included.

Abstract
In a code processing device, a rank assignment unit assigns ranks to sets of partial codes of original codes respectively, wherein, when the sets have different quality levels, a high rank is assigned to a set of partial codes having a low quality level, and when the sets have a same quality level and different resolution levels, a high rank is assigned to a set of partial codes having a low resolution level. A partial code selecting unit selecting sets of partial codes that have a quality specified by a specified quality value and are included in output codes, in order of the assigned ranks. A code forming unit forms the output codes in which the sets of selected partial codes are included.
