Abstract
An image storage device includes a storing unit, a background recognizing unit, an attribute-information generating unit, and an image-data processing unit. The storing unit stores therein image data and first attribute information for each pixel. The background recognizing unit recognizes a background of the image. The attribute-information generating unit generates second attribute information for each pixel based on the background of the image recognized by the background recognizing unit. The image-data processing unit processes the image data based on the second attribute information generated by the attribute-information generating unit.
Claims12
An image storage device comprising:
- a storing unit that stores therein image data of an image compressed by using a lossy compression method, and stores therein attribute information for each pixel of the image compressed by using a lossless compression method, the attribute information including a plurality of pieces of sub-attribute information;
- a background recognizing unit that recognizes a background of the image;
- an attribute-information generating unit that generates and updates sub-attribute information in the attribute information stored in the storing unit for each pixel based on the background of the image recognized by the background recognizing unit thereby updating the attribute information;
- and
- an image-data processing unit that processes the image data based on updated second attribute information.
A method of storing image data, the method comprising:
- storing image data of an image compressed by using a lossy compression method in a storing unit;
- storing attribute information for each pixel of the image compressed by using a lossless compression method in the storing unit, the attribute information including a plurality of pieces of sub-attribute information;
- recognizing a background of the image;
- generating and updating sub-attribute information in the attribute information stored in the storing unit for each pixel based on the background of the image recognized at the recognizing;
- and
- processing the image data in the storing unit based on the sub-attribute information generated at the generating.
A computer program product that includes a computer-readable recording medium that stores therein a computer program that causes a computer to implement a method of storing image data, the computer program causing the computer to execute:
- storing attribute information for each pixel of the image compressed by using a lossless compression method in the storing unit, the attribute information including a plurality of pieces of sub-attribute information;
- recognizing a background of the image;
- generating and updating sub-attribute information in the attribute information stored in the storing unit for each pixel based on the background of the image recognized at the recognizing;
- and
- processing the image data in the storing unit based on the sub-attribute information generated at the generating.
