Someone told me about a digital camera from the mid nineties which has Infinite Depth of Field. So the technique of the FocOz camera can be that ew after all?
‘Early’ digital cameras of the mid nineties had wideangel lenses of such short focal length and small sensors with so few pixels that depth of field limitations within a range of 1 meter up to infinity tended to be obscured by the generally poor image resolution, constituting a more severe restraint. The depth of field of these cameras was therefore ‘extended’ due to system limitations rather than image processing. As a corollary Depth of Field problems are now escalating for cameras with increasing numbers of pixels and extended use of telephoto lenses..
