Abstract
Methods and apparatuses are provided for changing the relative size of an image in a display that includes one or more edges that define a display area in which at least a portion of the image is displayed. The methods and apparatus provide for a zoom point, which corresponds to a point in the displayed image that is to be zoomed in the displayed image, to be selected. The relative size of the selected zoom point may then be changed while the selected zoom point is translated along a substantially straight zoom line that passes through the selected zoom point and extends between a central point in the display area and an edge point on the display area that is closest to the selected zoom point.
Claims30
In a display including one or more edges that define a display area in which at least a portion of an image including an image edge point is displayed, a method of changing the relative size of the image, comprising the steps of:
- selecting a zoom point in the displayed image, the zoom point corresponding to a point in the displayed image, the image edge point located at a position on the display area edge that coincides with an edge point on the display area;
- and
- changing the relative size of the displayed image while (i) translating the selected zoom point along a straight zoom line that passes through the selected zoom point and extends between a central point in the display area and the display area edge point and (ii) maintaining the position of the image edge point such that the image edge point remains coincident with the display area edge point,
- wherein, when the selected zoom point coincides with the central point in the display area, the selected zoom point does not translate while the relative size of the displayed image is changing.
A display device, comprising:
- a user interface operable to receive user input and supply one or more command signals;
- a display screen having a display area edge that defines an image display area in which a displayed image may be rendered, the displayed image including an image edge point located at a point on the display area edge;
- and
- a processor coupled receive the commands from the user interface and operable, in response thereto, to (i) select a zoom point in the displayed image that corresponds to a point in the displayed image (ii) change the relative size of the displayed image while translating the selected zoom point along a straight zoom line that passes through the selected zoom point and extends between a central point in the display area and the display area edge point and (iii) maintain the position of the image edge point while the relative size of the displayed image is changing such that the image edge point remains coincident with the display area edge point,
- wherein, when the selected zoom point coincides with the central point in the display area, the selected zoom point does not translate while the relative size of the displayed image is changing.
