Patent application numberDescriptionPublished
20080232693Image processing apparatus, image processing method, and computer program product - An image processing apparatus that detects a face area from image information includes a pattern database, a face-direction determining unit, and a face-area detector. The face-direction determining unit determines, as a face direction, a direction in which a face image in image information is upright based on determination pattern information stored in the pattern database. The face-area detector matches the direction of the image information with the direction of the determination pattern information based on the face direction, and detects a face area from the image information.09-25-2008
20080232698Object image detection method and object image detection device - An object image detection device is disclosed that is able to rapidly detect an object image from an input image. The object image detection device includes an image block generation unit to generate plural image blocks from the input image for detecting the object images, an image classification unit to determine whether each of the image blocks includes one or more of the object images by using one or more features of the object images, and acquire the image blocks including the object images to be object image candidates; and a detection unit to sequentially detect the object images from the object image candidates. The image classification unit acquires the object image candidates based on a relative positional relationship between the image blocks and already-acquired object image candidates.09-25-2008
20080253664Object image detection method and object image detection device - An object image detection device is disclosed that is able to rapidly detect an object image from an input image without a great deal of computation. The object image detection device includes an object image classification unit for determining whether the object images are included in an image having a given orientation, an image orientation detection unit for detecting orientation of the input image, an image rotation unit for rotating the object image classification unit according to the detected orientation of the input image, and a detection unit for detecting the object images from the input image by using the rotated object image classification unit.10-16-2008
20090109304Image processing device, image processing method, and computer program product - In an image capturing device, an image acquiring unit acquires image data captured for a subject, a distance information acquiring unit acquires a distance from the subject included within each region to a capturing position for the image data for each of a plurality of regions constituting the acquired image data, a distinguishing information acquiring unit acquires distinguishing information for distinguishing the subject from the image data, and a generating unit generates object regions the subject within the image data is divided up into each processing target from the image data based on the shooting distances and the distinguishing information.04-30-2009
20100027906Image processing unit, noise reduction method, program and storage medium - An image processing unit is disclosed that smoothens a notice pixel of input image data with pixel values of pixels around the notice pixel to reduce noise in the image data. The image processing unit includes an edge extraction unit that extracts an edge based on the pixel values of the image data; a region determination unit that determines a region to be processed where a sum of edge intensities of the pixels including the notice pixel becomes greater than or equal to a threshold; and a smoothening unit that changes a smoothening intensity in accordance with a size of the region to be processed to smoothen the notice pixel corresponding to the region to be processed.02-04-2010
20110122264IMAGING APPARATUS, IMAGE PROCESSING METHOD, AND COMPUTER PROGRAM PRODUCT - An imaging apparatus includes: an imaging unit that captures an image by photoelectrically converting a subject image; a feature calculating unit that calculates, per region included in the image, a feature value related to suitability for motion detection; a region-motion detecting unit that detects a motion vector per the region; and a whole-motion calculating unit that calculates a motion quantity of a whole image from the feature value and the motion vector.05-26-2011

20090147292Apparatus, system, and method for image processing - A confidential document is generated by encoding distribution destination information specifying a destination to which the confidential document will be distributed.06-11-2009
20090190182Apparatus, system, and method for image processing - An image processing apparatus includes an image information acquisition device, an embedment information acquisition device, an embedment mode information acquisition device, an embeddability determination device, and an embeddability information output device. The image information acquisition device acquires image information on a target image into which supplemental information is to be embedded. The embedment information acquisition device acquires embedment information on the supplemental information. The embedment mode information acquisition device acquires embedment mode information on an embedment mode in which the supplemental information is embedded in the image information. The embeddability determination device determines embeddability of the supplemental information into the image information based on the embedment mode information, the embedment information, and the image information. The embeddability information output device outputs determination-result information on a determination result of the embeddability determined by the embeddability determination device.07-30-2009
