Abstract

Abstract The display device for reproducing of images on a screen which is installed in an automotive vehicle for displaying the driving direction and location of the automotive vehicle within a graphic pattern, such as a drive map, comprises: a screen device (2), a first memory unit (11) in which data of a graphic pattern to be displayed on said screen device is stored, a second memory unit (10) in which at least one word and mark to be superimposed on the graphic pattern and those positional data on the graphic pattern are stored, a signal generator (3) which outputs a command signal to rotate the graphic pattern on said screen unit by an angle with respect to an original position, a shift circuit (12) which shifts the positions of all words and marks stored in said second memory unit (10) to those rotated at the angle corresponding to the command signal from said signal generator (3), and an image control unit (13) which controls the display of graphic pattern rotated by the angle corresponding to the command signal from said signal generator on said screen unit (2) and controls the superimpose of at least one word and mark stored in said second | memory unit (10) on the position of the graphic pattern shifted by said shift circuit (12).

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 240 words
An image display device having a screen unit, a memory for storing of data and/or image elements to be displayed via said screen unit, a screen control unit, and a signal generator for determining the relative position of graphical data in respect to the other data or image portions on the screen characterized by - a first memory unit (11) in which a graphic pattern to be displayed on said screen unit is stored; - a second memory unit (10) in which a character word to be superimposed on the graphic pattern and the coordinate position on said screen unit are stored; - a signal generator (3) which outputs a command signal to rotate the graphic pattern on said screen unit (2) by an angle with respect to a reference position of the graphic pattern; - a shift circuit (12) which shifts the coordinate position of the character word fetched from said second memory unit (10) on said screen unit to that rotated by the angle corresponding to the command signal from said signal generator (3); and - an image control unit (13) which rotates the graphic pattern displayed on said screen unit (2) by the angle corresponding to the command signal from said signal generator and simultaneously superimposes the character word whose position is shifted by said shift circuit on the rotated graphic pattern so as to always provide an upright view of the word from said screen unit.
Claim 2
Dependent Claim 240 words
An image display device having a screen unit, a memory for storing of data and/or image elements to be displayed via said screen unit, a screen control unit, and a signal generator for determining the relative position of graphical data in respect to the other data or image portions on the screen characterized by - a first memory unit (11) in which a graphic pattern to be displayed on said screen unit is stored; - a second memory unit (10) in which a character word to be superimposed on the graphic pattern and the coordinate position on said screen unit are stored; - a signal generator (3) which outputs a command signal to rotate the graphic pattern on said screen unit (2) by an angle with respect to a reference position of the graphic pattern; - a shift circuit (12) which shifts the coordinate position of the character word fetched from said second memory unit (10) on said screen unit to that rotated by the angle corresponding to the command signal from said signal generator (3); and - an image control unit (13) which rotates the graphic pattern displayed on said screen unit (2) by the angle corresponding to the command signal from said signal generator and simultaneously superimposes the character word whose position is shifted by said shift circuit on the rotated graphic pattern so as to always provide an upright view of the word from said screen unit.
Claim 3
Dependent Claim 39 words
The image display device as set forth in claim 1, which is installed in an automotive vehicle and said signal generator (3) outputs the command signal whose value changes according to a direction toward which the automotive vehicle travels.
Claim 4
Dependent Claim 34 words
The image display device as set forth in claim 2, wherein the graphic pattern is a drive map whose reference position is such that a north-and-south direction coincides vertical position of said screen unit.
