Apparatus and method for scaling layout of application program in visual display unit

PURPOSE: An apparatus for scaling layout of an application program in an image display device and a method thereof are provided to provide optimum application program layout to a user, by scaling the layout of the application program by considering distance from the user. CONSTITUTION: When layout of an application program is configured, an image display device checks reference pixels per degree (PPD) (101,103). The image display device checks PPD of the image display device (105). The image display device generates scaling variables by considering the reference PPD and the PPD of the image display device (107). The image display device configures the layout of the application program by considering the generated scaling variables (109). [Reference numerals] (101) Is a layout configured?; (103) Confirm a reference PPD; (105) Confirm a PPD of an image display device; (107) Generate scaling variables by considering a reference PPD and a PPD of an image display device; (109) Configure a layout by considering scaling variables; (AA) Start; (BB) No; (CC) Yes; (DD) End
