Abstract: An information processing apparatus is provided including a first display control unit for controlling display of an area to which to paste an image representing a content and selected to start reproduction of the content. A second display control unit displays a list of images when a display instruction to display the list of the images is given. Under control of the first display control unit, one screen including a different number of layers according to a category of data created in the area to which to paste the image is displayed in the area.

Abstract: An information processing apparatus according to the present invention includes: first display control unit for controlling display of an area to which to paste an image representing a content and selected to start reproduction of the content; and second display control unit for displaying a list of images when a display instruction to display the list of the images is given. Under control of the first display control unit, one screen including a different number of layers according to a category of data created in the area to which to paste the image is displayed in the area.

Abstract: To reduce the time for verification in lithographic data and reduce the turn-around-time in preparation of lithographic data, a first lithographic input data and a second lithographic input data are compared in their data formats to extract data of the first lithographic input data excluding data common to the second lithographic input data as a first difference data, or to extract data of the second lithographic input data excluding data common to the first lithographic input data as a second difference data. If the first difference data and the second difference data contain data, they are compared graphically to extract different data as a third difference data. If the third difference data contains data, the first lithographic input data and the second lithographic input data are acknowledged to have a difference therebetween.

Abstract: A method of generating mask pattern data for graphics and an apparatus for the same are provided wherein each line segment as a processing unit for graphic arithmetic processing is stored as data in tree structure evenly divided into two for every partial region obtained by plurally dividing the overall pattern data, and this partial region is formed by equally dividing the pattern data by m in an X axis direction, and among the regions, those which includes line segments intensively are further divided to form data of tree structure evenly divided into two for every divided region.
