Embodiment Construction

[0041] For a better understanding, the invention will now be explained in more detail in the following description with reference to the accompanying drawings. It should be understood that the invention is not limited to these exemplary embodiments, but that specified features may be suitably combined and / or modified without departing from the scope of the invention as defined in the appended claims.

[0042] In the following, reference is made to the application of the invention to film scanning. However, the invention is equally applicable to other fields such as plenoptic microscopy, object detection for microfiche and object detection problems in the field of plenoptic still picture imaging.

[0043] figure 1 The schematic layout of a film scanning device 1 for transferring analog images into the digital domain is shown. The device 1 can be divided into three main parts, namely: the light source 2, monochrome or white; the object to be scanned 3, i.e. film; and the light...

Abstract

A method and an apparatus (30) for handling a defect object in an image are described. A light field information retrieving unit (34) retrieves (20) a light field capture of the image. A view generator (35) generates (21) a center view (CV) and two or more side views (SV n ) from the light field capture. A defect determining unit (36) then determines (22) a defect object in the image through a comparison of the center view (CV) and the two or more side views (SV n ).

Description

technical field [0001] The present invention relates to methods and devices for processing defective objects in images. In particular, the present invention relates to methods and apparatus for handling scratched and dirty objects in scanned film. Background technique [0002] Although motion picture distribution via film is declining, there are still a large number of analog film archives that need to be transferred to the digital domain. Long-term archiving of valuable assets is still done on film. There will also be technologies for preserving digital data on film in the future. [0003] Today, technical solutions for transferring image information from analog to the digital domain are available not only for the professional motion picture film industry, but also for the semi-professional and amateur markets. These solutions are usually based on film scanning. [0004] When scanning analog film, there are many issues that affect image quality, such as the presence of ...
