Abstract: Conventional cameras and other optical instruments produce images upon one plane only. Objects at differing ranges from the lens of such cameras cannot appear upon that plane in-focus simultaneously, and the operator, hence the viewer, is obliged to choose one primary plane of interest in which the major subject lies; all other objects at other ranges will be out of focus.The invention described produces photographic images that are in-focus at all ranges.This is achieved by dividing the original scene into two or more images focussed upon different ranges, and eliminating from each image those parts that are out-of-focus. The remaining in-focus parts of each image are then reconstituted into a single image for presentation.The elimination of blurred parts may be done by comparison of one sub-image with another, or by the subjective intervention of an operator using a mathmatical support system.The images described may be applied to still or motion photography, film or electronic.
