Control Of Artificial Lighting Of A Scene To Reduce Effects Of Motion In The Scene On An Image Being Acquired

View page
US Patent:
7697836, Apr 13, 2010
Filed:
Oct 25, 2006
Appl. No.:
11/552717
Inventors:
Eli Pozniansky - Santa Clara CA, US
Shimon Pertsel - Sunnyvale CA, US
Assignee:
Zoran Corporation - Sunnyvale CA
International Classification:
G03B 15/03
US Classification:
396159, 396153, 396263
Abstract:
Motion of an image of a scene being captured by a digital image acquisition device is detected and used to control parameters of illumination of the scene by a flash lamp that is typically built into the device. Parameters that may be controlled include the intensity, duration and timing of light emitted by the flash lamp. Such control of the flash illumination is preferably performed in conjunction with adjusting one or more exposure parameters used to capture an image. Such exposure parameters include duration, aperture and sensor gain. Motion blur caused by movement of the camera or by movement of an object within the scene being photographed is reduced by selecting appropriate exposure parameters and flash light characteristics.

US Patent:
7714903, May 11, 2010
Filed:
Aug 29, 2006
Appl. No.:
11/467993
Inventors:
Shimon Pertsel - Sunnyvale CA, US
Ohad Meitav - Cupertino CA, US
Assignee:
Zoran Corporation - Sunnyvale CA
International Classification:
H04N 5/235
US Classification:
3482291
Abstract:
An image capture system is presented where the dynamic range of photo imaging devices, such as a still or video camera, is increased by varying sensor exposure time on a pixel-by-pixel basis under digital camera processor control. The systems photo sensors are continuously illuminated without reset over the exposure interval. In addition to being interrogated at the end of the exposure interval, the pixels are also non-destructively interrogated at one or more intermediate times during the interval. At each interrogation, the image capture system determines individually whether the pixels have saturated and if not, the parameter value is recorded; if the pixel has saturated, the previously stored value from the preceding interval is maintained. To produce the final sensor value for the whole exposure interval, the data for pixels that reached the saturation level are adjusted to compensate for their shortened exposure.

US Patent:
7719579, May 18, 2010
Filed:
May 24, 2005
Appl. No.:
11/137303
Inventors:
Alex Fishman - San Jose CA, US
Shimon Pertsel - Sunnyvale CA, US
Victor Pinto - Zychron-Yaakov, IL
Michael Shalev - Zichron Yaacov, IL
Assignee:
Zoran Corporation - Sunnyvale CA
International Classification:
H04N 5/76
H04N 5/228
US Classification:
34823199, 3482221, 382239
Abstract:
A digital camera acquires a first image in a sequence of images by loading it into a unified memory space of the digital camera in a first order and processing it in a second order. Before the first image is completely processed, the digital camera starts acquiring a second image and overwriting at least a processed portion of the first image in the unified memory space with image data of the second image.

Techniques For Modifying Image Field Data Obtained Using Illumination Sources

US Patent:
7755672, Jul 13, 2010
Filed:
May 15, 2006
Appl. No.:
11/383417
Inventors:
Shimon Pertsel - Sunnyvale CA, US
Assignee:
Zoran Corporation - Sunnyvale CA
International Classification:
H04N 9/73
H04N 5/235
H04N 5/222
G06K 9/40
US Classification:
3482241, 3482221, 348370, 382274
Abstract:
Techniques for modifying data of an image that can be implemented in a digital camera, video image capturing device and other optical systems are provided to correct for non-uniform illumination and/or effects of saturation appearing in data obtained using one or more artificial illumination sources. In an implementation, correction factors are derived using data from at least two images that have been captured with different illumination levels of the object scene and close in time to the capture of the image of interest. Typically, the image of interest is of higher resolution than at least one of the at least two images.

US Patent:
8189057, May 29, 2012
Filed:
Jun 5, 2009
Appl. No.:
12/479703
Inventors:
Shimon Pertsel - Sunnyvale CA, US
Eli Pozniansky - Santa Clara CA, US
Ohad Meitav - Cupertino CA, US
Assignee:
CSR Technology Inc. - San Jose CA
International Classification:
H04N 5/228
H04N 5/235
US Classification:
34820816, 348362, 348154
Abstract:
Quantities of motion regarding an imaging device such as an electronic camera are calculated and used to adjust the exposure time and one or more other exposure parameters used to capture an image to improve the quality of the image. Motion blur caused by movement of the camera or by movement of an object within the scene being photographed is reduced by selecting appropriate exposure parameters. Further, when there is little or no motion detected, the exposure parameters may be selected to improve the depth of field and reduce the noise in the captured image.
