Abstract
An image processing apparatus disclosed herein includes an extracting unit that extracts a pixel cluster of a predetermined size from input image data, and a coding unit that codes the input image data, based on correlation between pixel clusters extracted by the extracting unit.
Claims19
An image processing apparatus comprising:
- an extracting unit that extracts a pixel cluster of a predetermined size from input image data;
- and
- a coding unit that codes the input image data, based on correlation between pixel clusters extracted by the extracting unit.
An image processing apparatus comprising:
- an extracting unit that extracts a pixel cluster of a predetermined number of pixels from input image data;
- and
- a resolution changing unit that changes resolution of some of a plurality of color components of the input image data, by each pixel cluster extracted by the extracting unit.
An image processing apparatus comprising:
- a decoding unit that decodes a coded image data to generates a data set, which represents gradation values of pixels of image data, based on correlation between the decoded data;
- and
- a data dividing unit that divides values of the data set to extract gradation values of a plurality of pixels.
An image processing method comprising:
- extracting a pixel cluster of a predetermined number of pixels from input image data;
- and
- generating a data set which represents gradation values of pixels of image data;
- wherein
- the data set includes a plurality of gradation values of a first color component, and a fewer number of gradation values of a second color component than the gradation values of the first color component.
An image processing method comprising:
- extracting a pixel cluster of a predetermined-size from input image data;
- and
- coding the input image data, based on correlation between pixel clusters extracted.
An image processing method comprising:
- decoding a coded data to generate a data set, which represents gradation values of pixels of image data, based on correlation between the decoded data;
- and
- dividing values of the data set to extract gradation values of a plurality of pixels.
A storage medium readable by a computer, the storage medium storing a program executable by the computer to perform a function comprising:
- extracting a pixel cluster of a predetermined size from input image data;
- and
- coding the input image data, based on correlation between pixel clusters extracted.
A storage medium readable by a computer, the storage medium storing a program of instructions executable by the computer to perform a function comprising:
- decoding a coded data to generate a data set, which represents gradation values of pixels of image data, based on correlation between the decoded data;
- and
- dividing values of the data set to extract gradation values of a plurality of pixels.
An image processing method comprising:
- extracting a pixel cluster of a predetermined number of pixels from input image data;
- and
- changing resolution of some of a plurality of color components of the image data, by each pixel cluster extracted by the extracting unit.
A storage medium readable by a computer, the storage medium storing a program of instruction executable by the computer to perform the computer a function comprising:
- extracting a pixel cluster of a predetermined number of pixels from input image data;
- and
- changing resolution of some of a plurality of color components of the image data, by each pixel cluster extracted by the extracting unit.
