Patent number: 7801384Abstract: An image sensor array of active pixel elements is arranged in rows and columns. Each column has an output circuit for reading out pixel image signals. The output circuit includes a pair of sample capacitors, a switching circuit operable based upon pixel switches for applying pixel voltages to the pair of sample capacitors. At least one optically masked pixel is provided so that output image signals obtained therefrom represent substantially only the column fixed pattern noise (FPN). An image processing circuit records the column FPN for each column from the optically masked pixels, records the image signal from the sensor array of active pixels, and subtracts the column FPN column-wise from the image signal.Type: GrantFiled: May 7, 2004Date of Patent: September 21, 2010Assignee: STMicroelectronics Ltd.Inventors: Keith Findlater, Angelo Bosco

Patent number: 7792358Abstract: A color image sensor has a first, second, and third color component pixels. The third color component pixel includes more intensity information than the first and second color component pixels. A difference estimating section estimates difference in a signal level exerted on a pixel signal of the third color component pixel, using the pixel signal of a pixel peripheral to the third color component pixel. A correcting section corrects the pixel signal of the third color component pixel on the basis of the estimated difference. Accordingly, when the third color component is green in a Bayer array, a pixel signal of a green pixel in a row of red pixels becomes equal to the pixel signal of a green pixel in a row of blue pixels. Therefore, line crawling can be suppressed without smoothing an image.Type: GrantFiled: October 17, 2008Date of Patent: September 7, 2010Assignee: Nikon CorporationInventor: Masahiro Suzuki

Patent number: 7787707Abstract: Image-processing device for ROP is disclosed. Upon receiving a ROP command, the image-processing device determines whether the size of the brush data is required to be modified through a size modifying operation, based on the printing resolution of the printing device. If the size modifying operation is necessary, the image-processing device performs a process to enlarge or reduce the brush data, depending on the printing resolution. The image-processing device converts the ROP code associated with the operational expression using brush data to a combination of ROP codes associated with operational expressions using the source bitmap, but not brush data. The image-processing device controls a ROP processor to perform the ROP processes corresponding to these ROP codes using the enlarged or reduced brush data as the source bitmap in order to implement a ROP process equivalent to the ROP code inputted with the ROP command.Type: GrantFiled: August 10, 2005Date of Patent: August 31, 2010Assignee: Brother Kogyo Kabushiki KaishaInventors: Yuji Miyata, Kenichi Watanabe

Patent number: 7724961Abstract: A computer implemented method constructs a classifier for classifying test data. High-level features are generated from low-level features extracted from training data. The high level features are positive definite matrices in a form of an analytical manifold. A subset of the high-level features is selected. An intrinsic mean matrix is determined from the subset of the selected high-level features. Each high-level feature is mapped to a feature vector onto a tangent space of the analytical manifold using the intrinsic mean matrix. Then, an untrained classifier model can be trained with the feature vectors to obtain a trained classifier. Subsequently, the trained classifier can classify unknown test data.Type: GrantFiled: September 8, 2006Date of Patent: May 25, 2010Assignee: Mitsubishi Electric Research Laboratories, Inc.Inventors: Fatih M.

Patent number: 7689048Abstract: Image data is efficiently encoded using a predict coding unit and a run-length coding unit. The predict coding unit encodes a target pixel X on the basis of difference between the value of the target pixel and a predict value calculated from pixels neighboring the target pixel. The run-length coding unit starts the measuring the run when the number of colors contained in four pixels “a”, “b”, “c”, and “d” near the target pixel X is 1, and outputs encoded data of the run when the target pixel is different from an immediately preceding pixel “a”. Then, the predict coding unit starts the encoding. At this time, since the target pixel is different from the preceding pixel, the preceding pixel is excluded from references for generating the predict value. Instead of the preceding pixel, an pixel, which has been encoded, satisfying a specific condition is referred to.Type: GrantFiled: May 2, 2006Date of Patent: March 30, 2010Assignee: Canon Kabushiki KaishaInventors: Yuki Matsumoto, Hiroshi Kajiwara
