• fifth program code storing the processed document data so that a document is displayed on the display unit in accordance with the processed document data;
• and
• sixth program code facilitating switching between controlling a display layout of the display unit based on the detected display specification data and the detected layout data, so that a display size is appropriate for readability of text data elements in the document data is readable when being displayed on the display unit and controlling the display unit based on user input such that an image of at least one portion of the display layout is displayed on the display unit with a user-determined display size.

A display system in which a processed document data from original document data, in conformity with a display specification data stored in a storage device and a layout data contained in the original document data, is displayed on a monitor of a display unit, comprising:

• a central processing unit comprising:
• a display specification detection unit detecting a display specification data related to the display unit, the display specification data representing specifications of the display unit;
• a layout data detection unit detecting the layout data of the original document data, identifying text/image data elements through classification of the original document data, reading a maximum display resolution from text data elements, including an optimum font size;
• an operation unit utilized by a user to input a desired font type;
• the display memory storing the processed document data so that a document is displayed on the display unit in accordance with the processed document data,
• wherein the central processing unit reads document font data, calculates a font size of displayed text data in accordance with readability of the displayed text data, calculates a display size based on the calculated font size, generates the processed document data that reflects the display size calculated and the calculated font size in the desired font type, stores the processed document data into the storage device, transfers the processed document data from the storage device to the central processing unit, and supplies the processed document data to a display memory in the display unit so that the document data is displayed on the display unit in conformity with the display specification data and the layout data, such that data elements of the processed document data displayed on the monitor are allocated on the monitor according to a user-determined display layout based on the detected display specification data and the detected layout data page, and layout processing is carried out for data elements of the processed document data;
• and
• a display control unit facilitating switching between controlling the display layout of the display unit based on the detected display specification data and the detected layout data, so that a display size is appropriate for readability of text data elements in the processed document data when being displayed on the monitor and controlling the display unit, based on user input, such that an image of at least one portion of the display layout is displayed on the display unit with a user-determined display size.

A display system in which a processed document data from original document data, in conformity with a display specification data stored in a storage device and a layout data contained in the original document data, is displayed on a display unit, comprising:

• a display device, comprising:
• the display unit, receiving processed document data from a display memory;
• a display memory storing a processed document data so that a document is displayed on the display unit in accordance with the processed document data, wherein when a first display method is selected, an entire document data is displayed on the display unit with an original display size, and when the second display method is selected, at least one of the data elements of the document data is displayed with a user-determined display size on the display unit;
• a memory storing layout data, text data elements, and image data elements and display specification data;
• a central processing unit receiving the original document data, processing the original document data to provide layout data of the original document data, identify text/image data elements through classification of the original document data, read a maximum display resolution from text data elements, including an optimum font size, wherein the layout data contain layout information, comprised of data element identifiers, data element positions and page format data and are integrally stored with the document data and represent a page layout of data elements of the document data that are displayed, text data elements, and image data elements, and storing the layout data, text data elements, and image data elements in the memory detecting a display specification data related to the display unit, the display specification data representing specifications of the display unit, storing the display specification data in the memory, detecting display method instructions from a user, and selecting a display method based on user instructions;
