Method and apparatus for displaying images
First Claim
1. An apparatus for displaying a digital image of at least a portion of an object displayed in a film transparency corresponding to the position of a selected point of interest on the film transparency, the film transparency being of a type having object and alignment identifying indicia thereon, the apparatus comprising:
- a position sensitive panel having a surface for supporting the film transparency and further having an output for providing an output signal corresponding to a two dimensional spatial position of a selected point of interest on the panel;
an object identifying indicia reader having an output for providing an output signal corresponding to object identifying indicia read from the film transparency;
a storage device for storing data corresponding to a digital image of the object displayed in the film transparency; and
a display device for displaying digital images;
the apparatus further characterized in that it includes;
means for determining the horizontal, vertical and angular alignment of the film transparency relative to the position sensitive panel; and
a computer controller operatively connected to the position sensitive panel output, the object identifying indicia reader output, the storage device and the display device, and wherein the controller is adapted to receive output signals from the indicia reader and the position sensitive panel, to recall data corresponding to the object in the film transparency from the data storage device based upon the output signals received and the determined horizontal, vertical and angular alignment of the film transparency relative to the panel, and to display a digital image on the display of at least a portion of the object displayed in the film transparency corresponding to a selected point of interest on the transparency.

Abstract
A method and apparatus for displaying a digital image of at least a portion of an object displayed in a film transparency having object identifying indicia thereon is provided. The apparatus uses a position sensitive panel having a surface for supporting the film transparency and further having an output for providing an output signal corresponding to the two dimensional spatial position of a selected point of interest on the panel. The apparatus is further provided with an object identifying indicia reader having an output for providing an output signal corresponding to object identifying indicia on the film transparency. In one embodiment, a digital image of the object depicted on a film transparency can be displayed by simply touching the transparency which causes an associated computer controller to identify the transparency through the indicia thereon and recall corresponding digital image data. In another embodiment, a digital image of a selected point of interest on the film transparency can be displayed by touching the transparency at the desired location. The coordinates of the point touched on the panel together with the information contained in the indicia are provided to the associated computer controller to create the digital image display. The apparatus and method is particularly useful for fast screening of medical images with the added benefit of digital image enhancement capabilities when needed.

10. A method for displaying a digital image of a selected portion of an object displayed in a film transparency having object and alignment identifying indicia thereon, the method comprising the steps of:
-
(a) storing data corresponding to a digital image of an object on a storage device; (b) providing a film transparency displaying an image of the object and having object and alignment identifying indicia on a position sensitive panel having a surface for supporting the film transparency and further having an output for providing an output signal corresponding to the two dimensional spatial position of a selected point of interest on the panel; (c) reading the object identifying indicia on the film transparency to identify the object; (d) recalling the stored data from the storage device corresponding to the object identified by the identifying indicia read in step (c); (e) selecting a point of interest on the film transparency; (f) determining the horizontal, vertical and angular alignment of the transparency relative to the position sensitive panel and the coordinates of the selected point of interest on the film transparency; and (g) displaying a digital image of at least a portion of the object corresponding to the selected point of interest on the film transparency from the data recalled in step (d) and the horizontal, vertical, and angular alignment and the coordinates determined in step (f). - View Dependent Claims (11, 12)
