Method For Automatic Detection And Correction Of Halo Artifacts In Images

View page
US Patent:
8090214, Jan 3, 2012
Filed:
Dec 21, 2007
Appl. No.:
12/004855
Inventors:
Florian Ciurea - San Jose CA, US
Assignee:
Sony Corporation - Tokyo
Sony Electronics Inc. - San Diego CA
International Classification:
G06K 9/40
G06K 9/48
US Classification:
382275, 382242, 382266
Abstract:
A method of automatically detecting and correcting halo artifacts within a processed image is described. The method computes a two-dimensional (2D) gradient field of the original image and a 2D gradient field of the processed image. Each gradient field includes a gradient vector corresponding to each pixel. To detect halo artifacts, the gradient vector at each pixel of the original image is compared to the gradient vector at the corresponding pixel of the processed image. A halo artifact is determined to exist at a given pixel if a direction of the two corresponding gradient vectors differs by at least a specified threshold. To correct the halo artifacts, a composite gradient field is generated using one of three correction methods. A final image is generated by integrating the newly generated composite gradient field using known integration methods from a 2D gradient field such as ones based on the Fast Fourier Transform.

Method Of High Dynamic Range Compression With Detail Preservation And Noise Constraints

US Patent:
8144985, Mar 27, 2012
Filed:
Dec 21, 2007
Appl. No.:
12/004928
Inventors:
Florian Ciurea - San Jose CA, US
Alexander Berestov - San Jose CA, US
Assignee:
Sony Corporation - Tokyo
Sony Electronics Inc. - Park Ridge NJ
International Classification:
G06K 9/00
G06K 9/40
G03F 3/08
US Classification:
382168, 382274, 358520
Abstract:
A method for high dynamic range compression uses a modified cumulative histogram as a compression curve. This curve is computed from the cumulative histogram of the image with constraints that the local derivative on the curve does not exceed a certain limit. The limit is fixed along the curve or the limit is variable, taking into account noise characteristics at various pixel values. To provide appropriate detail preservation, a smoothing filter is used to separate the image into an illumination image, referred to as a base image, and a detail image, and the compression curve is applied to the base image only. The compression method provides high dynamic range compression of the image while preserving the global contrast perception. Conventional global algorithms for high dynamic range compression are not capable of achieving this result. The proposed high dynamic range compression method also minimizes noise amplification while lightening the dark areas during image compression.

View page
US Patent:
8259208, Sep 4, 2012
Filed:
Apr 15, 2008
Appl. No.:
12/103501
Inventors:
Florian Ciurea - San Jose CA, US
Alexander Berestov - San Jose CA, US
Assignee:
Sony Corporation - Tokyo
Sony Electronics Inc. - Park Ridge NJ
International Classification:
H04N 5/222
G06F 3/041
US Classification:
34833302, 345173
Abstract:
A camera and method which selectively applies image content adjustments to elements contained in the image material. By way of example, the method involves registration of user touch screen input and determination of the arbitrary extent of a specific element in the captured image material at the location at which touch input was registered. Once selected, the element can be highlighted on the display, and additional user input may be optionally input to control what type of adjustment is to be applied. Then the element within the captured image material is processed to apply automatic, or user-selected, adjustments to the content of said element in relation to the remainder of the captured image. The adjustments to the image element may comprise any conventional forms of image editing, such as saturation, white balance, exposure, sizing, noise reduction, sharpening, blurring, deleting and so forth.

International Classification:
G06K 9/00
US Classification:
382254, 382260
Abstract:

Detection Of Low Contrast For Image Processing

View page
US Patent:
8463037, Jun 11, 2013
Filed:
Mar 31, 2011
Appl. No.:
13/077404
Inventors:
Kensuke Miyagi - Sunnyvale CA, US
Florian Ciurea - San Jose CA, US
Pingshan Li - Sunnyvale CA, US
Assignee:
Sony Corporation - Tokyo
International Classification:
G06K 9/00
US Classification:
382172
Abstract:
There are many applications that conduct both generation of contrast or complexity level and motion estimation for video processing. The applications often use a block matching technique. An embedded system such as a personal digital camera is an example of such an application. Additionally, comparison of error differences around the location of minimum error in a motion estimation error table is able to be used to determine low contrast in a scene.

Adjustable Neutral Density Filter System For Dynamic Range Compression From Scene To Imaging Sensor

View page
US Patent:
20070242141, Oct 18, 2007
Filed:
Apr 14, 2006
Appl. No.:
11/404653
Inventors:
Florian Ciurea - San Jose CA, US
International Classification:
H04N 5/262
US Classification:
348239000
Abstract:
An apparatus and method that extend the graduated neutral density filter approach by implementing an in-camera adjustable neutral density filter are described. The adjustable neutral density filter is implemented by the means of a transmissive LCD. The transmissive LCD is controlled to form a mask image. This mask image is able to be computed using an acquired signal wherein the acquired signal is then inverted and blurred. In an embodiment, a splitter and an additional sensor are utilized to acquire a split signal and then modify the split signal for use as the mask image. The other split signal is filtered through the mask image and transmissive LCD. Images with a high dynamic range compression are ultimately captured.
