  • Patent number: 7697767
    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.

  • Patent number: 7626733
    Abstract: Efficient utilization of a memory medium is enhanced in an image-processing apparatus, in which encoded data of JPEG 2000 or Motion-JPEG 2000 are stored in the memory medium as a file. File size of the encoded data is adjusted close to, but not to exceed an integer multiple of a memory domain management unit (sector size) of the memory medium. Thereby, a memory domain assigned to the image file in its entirety, or almost in its entirety, is used effectively, improving the efficient utilization of the memory medium.
