ABSTRACT:
A method for viewing a representation of an overscanned captured image on a display that is incapable of displaying the full image as originally captured. The method comprises the steps of (1) digitizing the image to produce a first block of serial data elements where each data element represents at least one picture element of the image, (2) storing a first data block in a data processing memory, (3) computing a second data element block by removing every nth data element from the first data element block, where n is an integer less than the number of first data block elements and said second data block element represents a reduced size image, and (4) displaying the second data element block overlayed upon at least a portion of the digitized image. The invention also includes an apparatus for viewing a representation of an overscanned captured image. The apparatus consists of a camera for digitizing the image, a data processing means including means for storing a first block of data from the digitizing camera representing the captured and digitized image, computing a second data block from a first data block of the digitized image data by removing every nth data element of the first data block, where n is less then the number of elements in the first data block, and a display for accessing the data processor to display the second data block overlayed upon at least a portion of the digitized image.
