Abstract:
1. A digital camera having a memory and an operational scan mode wherein: the camera takes a sequence of still pictures, which are temporarily stored in a cache, while sweeping the camera along a path; a first picture is stored in the memory; the amount of overlap between a next one of the pictures, from the cache, and said first picture is determined, wherein said next one of the pictures, from the cache, in the sequence is selected for being stored in the memory based on the amount of overlap regarding a picture content with said first picture stored in the memory; and the camera processes the pictures stored in the memory so as to create a composite picture and determines whether said composite picture includes an area lacking coverage by the pictures stored in said memory, wherein a content of said area is determined by interpolating-pixel data from edges of said area of said composite picture lacking coverage; and providing directions of said camera to a position to take at least one extra still picture to cover said area lacking coverage when interpolating pixel data from edges of said area of said composite picture lacking coverage fails to provide coverage of said area; and integrating said at least one extra still picture into said composite picture.
