Abstract
The present disclosure teaches a method and apparatus for displaying relatively higher resolution image using a lower resolution display element. The preferred embodiment of the invention operates to display a high resolution image by use of a plurality of frames of lower resolution images, with the lower resolution frames being shifted relative to one another by use of an optical element which alters the light path of the display.
Claims11
The method of displaying an image comprising a first number of image elements, said method utilizing a display device which displays said first number of image elements by time sequential display of a plurality of sets of lesser numbers of said image elements, said plurality of sets including a first set and a second set, said method including the steps of:
- a) providing said first set in response to said first number of image elements;
- b) utilizing said display device to display said first set via an optical path having at least one optical element;
- c) providing at least said second set in response to said first number of image elements;
- d) after step b) utilizing said display device to display said second set via an optical path obtained by altering the position of said optical element.
The method of displaying an image made up of a first number of image elements, on a surface, said method utilizing a display device having a second smaller number of display pixels, said method including the steps of:
- a) selecting a first set of said image elements;
- b) with said display device, displaying said first set on said surface via an optical path having at least one optical element;
- c) selecting at least a second set of said image elements;
- d) displaying said second set on said surface via said optical path which is changed by altering the position of said optical element.
The method of displaying an image of a first resolution which is made up of image elements, said method utilizing a display device of lower resolution and including the steps of:
- a) providing a first set of display elements in response to said image elements;
- b) using said first set of display elements to display a first lower resolution image with said display device;
- c) providing at least a second set of display elements in response to said image elements;
- d) using said second set of display elements to display a second lower resolution image with said display device after said display of step b);
- e) optically altering the display of at least one of said first and said second lower resolution images in order that individual image elements of each said set are displaced from each other when displayed.
An apparatus for displaying an image made up of a first number of image elements arranged in an array of lines of elements thereby having a first resolution, said apparatus using a display device which displays a second lower number of display pixels arranged in a frame, said apparatus including:
- a) a frame circuit responsive to said image and providing a plurality of lower resolution frames of said image elements as compared to said first resolution, said plurality of lower resolution frames including a first frame and a second frame;
- b) a display circuit utilizing said display device to sequentially display said plurality of lower resolution frames of image elements via an optical path;
- c) a deflection circuit for moving an optical element in said optical path thereby causing deflection of said display of one or more of said plurality of low resolution frames.
An apparatus for displaying an image made up of a first number of image elements arranged in an array of lines of elements thereby having a first resolution, said apparatus using a display device which displays a second lower number of display pixels arranged in a frame, said apparatus including:
- a) a frame circuit responsive to said image and providing a plurality of lower resolution frames of said image elements as compared to said first resolution, said plurality of lower resolution frames including a first frame and a second frame;
- b) a display circuit utilizing said display device to sequentially display said plurality of lower resolution frames of image elements via an optical path;
- c) a deflection circuit for moving an optical element in said optical path thereby causing said optical element to take on a first position during the display of said first frame of b) and a second position during the display of said second frame of b).
The method of displaying a plurality of images in time sequential fashion at different positions, said images being made up of pixels, said method including the steps of:
- a) providing said plurality of images to a display in time sequential fashion, said plurality including at least said first image and said second image;
- b) displaying said first image along an optical path;
- c) after step b), displaying said second image along said optical path;
- d) altering said optical path to cause said first image and said second image to be displayed at different positions thereby interleaving said pixels thereof.
