Patent number: 8934140Abstract: A color gamut of image data is appropriately subjected to a smoothing processing to print an image of favorable color reproduction and gradation reproduction. Specifically, when an average lightness is equal to or lower than a blacking lightness, the object pixel is not subjected to the smoothing processing.

In this manner, a pixel for which the object pixel has the average lightness equal to or lower than the blacking lightness is blacked and a pixel having a signal value higher than the blacking lightness is not compressed to the black point. The resultant image has no deteriorated gradation characteristic when being macroscopically observed.Type: GrantFiled: March 27, 2008Date of Patent: January 13, 2015Assignee: Canon Kabushiki KaishaInventors: Ayumi Hori, Fumihiro Goto, Yusuke Hashii, Tetsuya Suwa, Fumitaka Goto

The first attribute image generation unit is configured to determine a first attribute value from an input image to generate a first attribute image. The second attribute image generation unit is configured to determine a second attribute value from the input image to generate a second attribute image. The foreground image generation unit is configured to generate a foreground image expressing color information in the specific region according to the input image, the first attribute image, and the second attribute image. Further, the foreground image generation unit is configured to switch a method of determining a pixel value of a target pixel of the foreground image according to contents of the first attribute image and the second attribute image in a reference region.Type: GrantFiled: September 26, 2013Date of Patent: October 28, 2014Assignee: Oki Data CorporationInventor: Tetsuaki Kuwano

Publication number: 20140314312Abstract: An edge graph in which a pixel of an image is set as a node and an edge is set between nodes is generated. The dissimilarity or similarity between nodes at the two ends of the edge is used as the feature amount of the edge, and the edge is classified into one of a plurality of classes based on the feature amount. The edge of interest is selected in ascending class order of the feature amount, and it is determined whether to merge determination target regions to which the nodes at the two ends of the edge of interest belong. Determination target regions determined to be able to be merged are merged, and a feature amount in the merged region is updated.Type: ApplicationFiled: April 9, 2014Publication date: October 23, 2014Inventors: Noriyasu Hashiguchi, Yusuke Yachide

Patent number: 8867832Abstract: A method for detecting and removing scrolling texts comprising a step of using an adaptive transient difference processing of video communication to conduct frame calculation, wherein the adaptive transient difference processing takes first N frames fjkt?N and a current frame fjkt, and subtracts them to obtain a frame difference; and if the frame difference is greater than a threshold value, it is determined that the current frame fjkt has scrolling texts; and interpolates the first N frames before the current position of the scrolling texts to replace the current frame fjkt to achieve the goal of hiding the scrolling texts during video communication to enhance the viewing effect.Type: GrantFiled: February 1, 2013Date of Patent: October 21, 2014Assignee: National Yunlin University of Science and TechnologyInventors: Shih-Chang Hsia, Chien-Hung Liu

Patent number: 8861845Abstract: Systems and methods of detecting and correcting redeye in an image are described. In one aspect, pixels of the input image are segmented based on projections of color values of the pixels onto two-dimensional thresholding planes. Candidate redeye pixel areas are identified in the input image based on the segmented pixels of the input image.Type: GrantFiled: January 21, 2008Date of Patent: October 14, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: Huitao Luo, Jonathan Yen, Daniel Tretter

Patent number: 8861847Abstract: A system and method for detecting human skin tone in one or more images. The system includes an image processing module configured to receive an image and provide contrast enhancement of the image so as to compensate for background illumination in the image. The image processing module is further configured to detect and identify regions of the contrast-enhanced image containing human skin tone based, at least in part, on the utilization of multiple color spaces and adaptively generated thresholds for each color space. A system and method consistent with the present disclosure is configure to provide accurate detection of human skin tone while accounting for variations in skin appearance due to a variety of factors, including background illumination and objects.Type: GrantFiled: December 21, 2012Date of Patent: October 14, 2014Assignee: Intel CorporationInventors: Sadagopan Srinivasan, Michael E. Kounavis, Rameshkumar G. Illikkal, Ravishankar Iyer

Patent number: 8855412Abstract: Embodiments include a method of image processing including decomposing a reflectance spectrum for a test surface into a linear combination of reflectance spectra of a set of test targets. The coefficient vector calculated in this decomposition is used to predict a response of an imaging sensor to the test surface. A plurality of such predicted responses may be used for various applications involving color detection and/or classification, including human skin tone detection.Type: GrantFiled: March 20, 2012Date of Patent: October 7, 2014Assignee: QUALCOMM IncorporatedInventors: Shuxue Quan, Chinchuan Andrew Chiu, Xiaoyun Jiang
