Patent number: 7538815Abstract: Described are autofocusing algorithms and system implementations for machine inspection applications. The disclosed algorithms depend neither on the type of image (visual, infrared, spectrometric, scanning, etc.) nor on the type of image detector. Disclosed image filtering techniques, image focus measure functions and adaptive velocity control methods can be used in computer-based inspection systems for many different types of cameras and detectors as well as for a variety of magnification levels. The proposed autofocusing system can utilize the existing imaging hardware of the inspection system and does not require any additional components.Type: GrantFiled: January 23, 2003Date of Patent: May 26, 2009Assignee: Marena Systems CorporationInventors: Sergey Belikov, Marian Enachescu

Patent number: 7538799Abstract: A system and method for detecting flicker in a digital image. The system and method detects flicker by performing a frame-to-frame comparison of image data. The frame-to-frame comparison of image data is based on dividing each image into multiple columns, and performing a weighted sum of the pixel luminance in each column using a pattern of alternating sign weights. The weighted sum of luminance for each column in a first frame is compared to the weighted sum of luminance for that column in a second frame to determine if there is a simultaneous luminance variation in those columns. For example, if the difference between weighted sums of luminance between frames exceeds a threshold value in a predetermined number of columns then there is a simultaneous luminance variation in those columns, and a horizontal pattern of flicker has been detected in the image data.Type: GrantFiled: January 14, 2005Date of Patent: May 26, 2009Assignee: Freescale Semiconductor, Inc.Inventor: Arnold W. Yanof

Patent number: 7532242Abstract: A series of time delay integration TDI stages each integrate a photocurrent from a separate detector such as detectors in an array. In a first stage 20, a first integrator is initialized with a fixed bias 30, and integrates a signal from a first detector 22 during a first time interval. Next, a reset switch 26n causes that integrated first detector signal to bias a second integrator 24n. During a second integration interval, the second integrator integrates a signal from a second detector 22n. Multiple stages may be arranged in series so that an integrated signal from a previous stage biases an integrator in the current stage. At a final stage, an Nth integrator outputs the resulting signal Vfinal. Any bias used to initialize the first integrator is removed from Vfinal to achieve a total integrated signal from the detectors. A bi-directional switch 38 at each stage enables a forward or backward scan of the detectors.Type: GrantFiled: July 26, 2004Date of Patent: May 12, 2009Assignee: Raytheon CompanyInventor: Bryan J. Chen

Patent number: 7525589Abstract: A video outputting method is provided, in which a standard image is displayed, and has a standard aspect ratio. A widescreen (wide) image is displayed, and has a widescreen aspect ratio that is horizontally longer than the standard aspect ratio. Upper and lower blank masked regions are created along and outside upper and lower edges of the standard and widescreen images irrespective of the standard and widescreen aspect ratios. So first and second processed images are created by addition of the upper and lower blank masked regions, for outputting to a widescreen (wide) display device. A lateral blank masked region is created along and outside each one of two lateral edges of the standard image. The first processed image is created further by addition of the lateral blank masked region. The widescreen display device, when the processed images are input, cuts off the upper and lower blank masked regions.Type: GrantFiled: August 26, 2004Date of Patent: April 28, 2009Assignee: FUJIFILM CorporationInventor: Mikio Sasagawa

Patent number: 7525572Abstract: A shake sensor outputs an analog shake detection signal representative of a shake of a camera body. An amplifier operates for amplifying the analog shake detection signal to generate an analog amplification-resultant signal. The analog shake detection signal and the analog amplification-resultant signal are converted into a digital shake detection signal and a first digital amplification-resultant signal, respectively. A signal value represented by the digital shake detection signal is amplified on a digital basis to generate a second digital amplification-resultant signal. A decision is made as to whether or not the signal value represented by the first digital amplification-resultant signal remains greater than a predetermined reference value during at least a prescribed time interval. One is selected from the first and second digital amplification-resultant signals in response to the result of the decision. A shake corrective signal is generated in response to the selected signal.Type: GrantFiled: March 22, 2004Date of Patent: April 28, 2009Assignee: Victor Company of Japan, Ltd.Inventors: Hidehiro Katoh, Yutaka Ichinoi

Patent number: 7518649Abstract: An image pickup apparatus is provided which enables a user to follow up an object while viewing a display screen, and can prevent an image shake from being reflected on the display screen. An image pickup device outputs a signal in response to light received from an object via a lens section unit. A drive ring is rotated by the driving force of the AF motor to enable the lens section unit to move in a direction along the optical axis, to thereby carry out focus adjustment based on the signal output from the pickup device. A LCD displays an image based on the signal output from the image pickup device. The LCD displays the image according to through display when the lens section unit is being moved in a direction of extension, and the through display by the LCD is restrained after the lens section unit is reversed and is moved in a direction of retraction and until it is stopped.Type: GrantFiled: January 31, 2005Date of Patent: April 14, 2009Assignee: Canon Kabushiki KaishaInventor: Taro Murakami

Patent number: 7518642Abstract: A method for conveniently applying various effects to a captured digital image is disclosed. A digital camera to carry out the method includes a reader to image manipulation instructions printed on a card and an image printer for printing manipulated images. The method involves reading the image manipulation instructions from the card and manipulating a pre-captured image on the basis of the instructions. Complex manipulations can be readily carried out by inserting a sequence of the cards in a particular order to apply a desired effect to the captured image. Once the desired image manipulations have been applied the manipulated image is printed out.Type: GrantFiled: December 17, 2004Date of Patent: April 14, 2009Assignee: Silverbrook Research Pty LtdInventor: Kia Silverbrook

Patent number: 7518646Abstract: A solid state imager converts analog pixel values to digital form on an arrayed per-column basis. An N-bit counter supplies an N-bit DAC to produce an analog ramp output with a level that varies corresponding to the contents of the counter. A ripple counter or equivalent is associated with each respective column. A clock supplies clock signals to the counter elements. A comparator in each column gates the counter element when the analog ramp equals the pixel value for that column. The contents of the counters are transferred sequentially to a video output bus to produce the digital video signal. Additional black-level readout counter elements can create and store a digital value that corresponds to a dark or black video level. A subtraction element subtracts the black level value from the pixel value to reduce fixed pattern noise. An additional array of buffer counter/latches can be employed.Type: GrantFiled: September 20, 2005Date of Patent: April 14, 2009Assignee: Panavision Imaging LLCInventors: Jeffrey J. Zarnowski, Ketan V. Karia, Thomas Poonnen
