Patent number: 9536284Abstract: A method and a system are described where the quality of an image can be modified, using formatted information related to the defects of the appliances of the chain of appliances. The method may include compiling directories of sources of formatted information related to the said appliances, searching automatically for this formatted information related to the appliances of the said chain of appliances, modifying the said image automatically by image-processing software or components by taking into account the formatted information. Additionally, the formatted information may be modified as a function of variable characteristics of the image to be processed and of the chain of appliances. Thus, it is possible to process the images derived from appliances that may be of diverse origins and that have been commercialized gradually over time, such as photographic or video images in optical instrumentation, industrial controls, robotics, metrology, etc.Type: GrantFiled: September 9, 2013Date of Patent: January 3, 2017Assignee: DxO LabsInventors: Bruno Liege, Frederic Guichard, Jean-Marc Lavest

Patent number: 8994873Abstract: A system for capturing at least one image of a scene. The system estimates at least one value representative of the sharpness in at least one area of at least one initial captured image of a scene. The autofocus module captures the initial image with a predefined focus. On the basis of at least the value representative of the estimated sharpness, the system selects a first operating mode or a second operating mode. In the first mode, the autofocus module controls the focus of the system to capture a sharper image of the scene. In the second mode, the initial captured image or another captured image is processed by the digital processing unit, the other image being captured with the predefined focus.Type: GrantFiled: August 6, 2010Date of Patent: March 31, 2015Assignee: DXO LabsInventors: Ghislain Devaux, Frédéric Guichard, Etienne Knauer, Bruno Liege, Hoang-Phi Nguyen, Regis Tessieres

Patent number: 8331030Abstract: In order to increase the depth of field of an optical system, there is provision to add a phase object, interposed between an object (O) to be imaged and an image plane (8) of the optical system. The phase object is interposed although a chromatic aberration of the system is not yet corrected. After interposition, the measured optical signal is corrected complementarily so as to eliminate the chromatic aberrations therefrom. It is shown that if a parameter of the expansion of the expression, a function of pupil dependency, that the difference in path length of the optical system possesses a significant value of higher order than that of the defocus, then an increase in the depth of field is obtained.Type: GrantFiled: July 9, 2008Date of Patent: December 11, 2012Assignee: DXO LabsInventors: Bruno Liege, Regis Tessieres, Frederic Guichard, Etienne Knauer, Hoang-Phi Nguyen

Patent number: 8270083Abstract: To increase the depth of field of an optical system, an inversion of the chromatism is produced. This accommodates the fact that, in natural light, users prefer, for their photographs, taking long distance shots outdoors, where the illuminant is mostly composed of blue, and short-distance shots indoors, where the illuminant is mostly composed of red. While optical devices naturally focus the blue components at a shorter distance than the red components, which is unfavorable, with an inversion of the chromatism, a focus more in keeping with what is required is restored.Type: GrantFiled: July 7, 2008Date of Patent: September 18, 2012Assignee: DXO LabsInventors: Bruno Liege, Regis Tessieres, Frederic Guichard, Etienne Knauer, Hoang-Phi Nguyen

Publication number: 20120127360Abstract: The invention relates to a system for capturing at least one image of a scene. The system comprises: an optical system, a sensor, an autofocus module for adjusting the focus of the system, and a digital processing means. The system estimates at least one value representative of the sharpness in at least one area of at least one initial captured image of a scene. The autofocus module captures the initial image with a predefined focus. On the basis of at least the value representative of the estimated sharpness, the system selects a first operating mode or a second operating mode. In the first mode, the autofocus module controls the focus of the system to capture a sharper image of the scene. In the second mode, the initial captured image or another captured image is processed by the digital processing means, the other image being captured with the predefined focus.Type: ApplicationFiled: August 6, 2010Publication date: May 24, 2012Inventors: Ghislain Devaux, Frédérie Guichard, Etienne Knauer, Bruno Liege, Hoang-Phi Nguyen, Regis Tessieres
