Digital camera with variable size delete buffer

摘要

A digital camera and method that provide the ability to dynamically partition memory (both internal and removable) into memory dedicated for saved images and memory dedicated for deleted images. Deleted images may occupy as much memory as is available down to a user or factory selectable minimum. When a user deletes an image it is moved from a saved memory partion into a deleted memory partition, and when the memory partition dedicated to deleted images is full, then images are automatically and permanently deleted. In a preferred embodiment, the deleted images are automatically and permanently deleted on a first-in first-deleted basis. The deleted memory partition may be a physical memory partition or may correspond to indexed memory locations of the deleted images.
