Abstract
Embodiments of the invention provide an image display mode for displays, such as a television, that do not use the entire display field for displaying an image. A user selectable modification of the image display is provided, where the image may be stepped a predefined column of pixels, or predefined row of pixels, depending on viewing format, at a time at a very slow rate. The image may be stepped a predefined column of pixels per predefined time period until it is entirely to one side of the display, at which point it may be slowly stepped back to the other side of the display.
Claims16
A method for enabling viewing of a smaller format image on a larger format display, comprising:
- determining that a user has selected a dither function;
- in response to the dither function being selected, determining image position on the display, display limits and a predefined step size;
- and
- moving the image across the display at intervals according to the predefined step size until the user exits the dither function, wherein the predefined step size is based on a line frequency, and wherein the image movement is imperceptible to viewers.
A computer-readable medium encoded with instructions capable of being executed by a computer, cause a computer to:
- determine that a user has selected a dither function;
- in response to the dither function being selected, determine image position on the display, display limits and a predefined step size;
- and
- move the image across the display at intervals according to the predefined step size until the user exits the dither function, wherein the predefined step size is based on a line frequency, and wherein the image movement is imperceptible to viewers.
An apparatus, comprising:
- a display device to determine that a user has selected a dither function and in response to the dither function being selected, to determine image position on the display, display limits and a predefined step size and move the image across the display at intervals according to the predefined step size until the user exits the dither function, wherein the predefined step size is based on a line frequency, and wherein the image movement is imperceptible to viewers.
A system comprising:
- a memory;
- a clock;
- and
- a controller to determine that a user has selected a dither function and in response to the dither function being selected, to determine image position on the display, display limits and a predefined step size and move the image across the display at intervals according to the predefined step size until the user exits the dither function, wherein the predefined step size is based on a line frequency, and wherein display parameters are stored in memory and step size is determined in accordance with the clock.
