20090279801 | DECODING DEVICE, DECODING METHOD, DECODING PROGRAM, AND INTEGRATED CIRCUIT - A decoding device that improves the cache hit rate in the decoding process of compressed encoded image data. The decoding device, before the decoding process, generates a sort table for each reference picture for a plurality of MPEG data streams included in a GOP and having a frame type of P- or B-picture. The decoding device, by using the generated sort table, selects a group of pictures composed of a plurality of decoding target macro blocks that refer to the same reference macro block. The decoding device obtains, from the reference picture, four macro blocks including the same reference macro block referred to by the selected picture group, and stores the four macro blocks into the cache memory. The decoding device sequentially decodes each decoding target macro block included in the selected picture group, by using the four macro blocks stored in the cache memory. | 11-12-2009 |
20100007751 | IMAGE CORRECTION DEVICE, METHOD, PROGRAM, INTEGRATED CIRCUIT, AND SYSTEM - An image correction device trims an image, which has been captured by a camera provided in a moving object, in accordance with a predetermined image frame to generate a corrected image that is enclosed by the predetermined image frame, and then outputs the corrected image as an output image. Even when there is an error between an actual camera position in which the camera is actually positioned and a scheduled camera position in which the camera is scheduled to be positioned, the image correction device (i) decomposes the error into a first component that extends along an imaging direction of the camera and a second component that extends along a plane orthogonal to the imaging direction, (ii) shifts the image frame in accordance with the first component, and (iii) enlarges or shrinks a size of the image frame in accordance with the second component. | 01-14-2010 |

20120105578 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - Both tilt information included in an image and positional information are acquired in order to calculate a relative tilt angle between at least two images. Whether the tilt information can be used to estimate the tilt angle (whether the tilt information is fake information) is determined from a distribution characteristic in the image of the acquired positional information. The tilt angle is estimated from the tilt information determined to be able to be used. A tilt included in the acquired image is corrected using the estimation result, and the image having the correct orientation can be produced. | 05-03-2012 |
