Apparatus and method for converting an object display description document
First Claim
1. An apparatus for converting an original set of source objects by reducing the number of objects required to display a description document, said apparatus comprising a generating means for generating a set of new objects, from said original set of source objects in the document, a number of new objects in said set of new objects being fewer than a number of objects in said original set of source objects, said fewer objects obtaining a display image equivalent to the display of an image obtained from said original set of source objects,wherein said generating means generates said new objects from a semi-transparent source object and other source objects located at a layer lower than a layer including said semi-transparent source object and spatially overlapping said semi-transparent source object,wherein said generating means generates a new merged object including at least a first source object having an area and a second source object having an area and superimposed on said first source object.

Abstract
There is provided an apparatus for converting an object display description document, which enables to reduce load for displaying an image and a capacity necessary for storing document data. A browser including the apparatus is also provided. The apparatus comprises a generating means for generating, from a set of source objects in a document, a set of new objects to obtain a display image equivalent to a display image obtained from the set of source objects. The new objects are fewer than the set of source objects.

1. An apparatus for converting an original set of source objects by reducing the number of objects required to display a description document, said apparatus comprising a generating means for generating a set of new objects, from said original set of source objects in the document, a number of new objects in said set of new objects being fewer than a number of objects in said original set of source objects, said fewer objects obtaining a display image equivalent to the display of an image obtained from said original set of source objects,
wherein said generating means generates said new objects from a semi-transparent source object and other source objects located at a layer lower than a layer including said semi-transparent source object and spatially overlapping said semi-transparent source object, wherein said generating means generates a new merged object including at least a first source object having an area and a second source object having an area and superimposed on said first source object.

9. A method for converting an original set of source objects by reducing the number of objects required to display a description document, said method comprising a step of using a processor to generate a set of new objects, from said original set of source objects in the document, a number of said new objects forming a set of new objects fewer than a number of said source objects forming said original set of source objects, to obtain a display image equivalent to the display image obtained from said set of source objects,
wherein said generation step generates said new objects from a semi-transparent source object and other source objects located at a layer lower than a layer including said semi-transparent source object and spatially overlapping said semi-transparent source object, wherein said generating step generates a new merged object including at least a first source object having an area and a second source object having an area and superimposed on said first source object.

17. A storage device having stored thereon a computer program for causing a computer to execute a method for converting an object display description document by reducing the number of objects required for the display, said method comprising a generation step of generating, from an original set of source objects in the document, a set of new objects which are fewer than a number of said objects forming said original set of source objects, in order to obtain a display image equivalent to the display image obtained from said original set of source objects,
wherein said generation step generates new objects from a semi-transparent source object and other source objects located at a layer lower than a layer including said semi-transparent source object and spatially overlapping said semi-transparent source object, wherein said generating step generates a new merged object including at least a first source object having an area and a second source object having an area and superimposed on said first source object.

25. An apparatus for converting an original set of source objects by reducing the number of objects required to display a description document, said apparatus comprising a generating means for generating a set of new objects, from said original set of source objects in the document, a number of new objects in said set of new objects being fewer than a number of objects in said original set of source objects, said fewer objects obtaining a display image equivalent to the display of an image obtained from said original set of source objects,
wherein said generating means generates said new objects from a semi-transparent source object and other source objects not semi-transparent and located at a layer lower than a layer including said semi-transparent source object and spatially overlapping said semi-transparent source objects, wherein said generating means generates a new merged object including at least a first source object and a second source object superimposed on said first source object.

26. A method for converting an original set of source objects by reducing the number of objects required to display a description document, said method comprising a step of using a processor to generate a set of new objects, from said original set of source objects in the document, a number of said new objects forming a set of new objects fewer than a number of said source objects forming said original set of source objects, to obtain a display image equivalent to the display image obtained from said set of source objects,
wherein said generation step generates said new objects from a semi-transparent source object and other source objects not semi-transparent and located at a layer lower than a layer including said semi-transparent source object and spatially overlapping said semi-transparent source object, wherein said generating step generates a new merged object including at least a first source object and a second source object superimposed on said first source object.
