Abstract
Abstract The present invention relates to apparatus for converting an image data stream into output data for use in printing or displaying the image in a page comprising dividing means for dividing the image data into blocks of data, and processing means for processing the blocks of data so as to generate the output data. According to the invention the apparatus is characterised in that the dividing means comprises means (14) for selecting independent items of image data to form the blocks of data (16), and in that the processing means comprises first converting means (22) for converting each item of image data in the blocks into an intermediate form object (20), selecting means (24) for selecting the intermediate form objects so as to form groups of objects (26) each group relating to a geographical area of a page in which a portion of the image is to be printed or displayed, and second converting means (30) for converting the groups of objects into output data (13) for use in printing or displaying each portion of the image in the corresponding geographical area of the page. The invention also relates to a method for converting an image data stream into output data for use in printing or displaying the image using apparatus as above.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
173 words
Apparatus for converting an image data stream into output data for use in printing or displaying the image in a page comprising dividing means for dividing said image data into blocks of data, and processing means for processing said blocks of data so as to generate said output data, characterised in that said dividing means comprises means (14) for selecting independent items of image data to form said blocks of data (16), and in that said processing means comprises first converting means (22) for converting each item of image data in said blocks into an intermediate form object (20), selecting means (24) for selecting said intermediate form objects so as to form groups of objects (26) each group relating to a geographical area of a page in which a portion of said image is to be printed or displayed, and second converting means (30) for converting said groups of objects into output data (13) for use in printing or displaying each portion of said image in the corresponding geographical area of said page.
Claim 2
Dependent Claim
173 words
Apparatus for converting an image data stream into output data for use in printing or displaying the image in a page comprising dividing means for dividing said image data into blocks of data, and processing means for processing said blocks of data so as to generate said output data, characterised in that said dividing means comprises means (14) for selecting independent items of image data to form said blocks of data (16), and in that said processing means comprises first converting means (22) for converting each item of image data in said blocks into an intermediate form object (20), selecting means (24) for selecting said intermediate form objects so as to form groups of objects (26) each group relating to a geographical area of a page in which a portion of said image is to be printed or displayed, and second converting means (30) for converting said groups of objects into output data (13) for use in printing or displaying each portion of said image in the corresponding geographical area of said page.
