20080205510 | Apparatus and method for converting a compressed video stream with preview of converted stream - An apparatus by which a user can easily set a parameter for conversion when a compression encoding system of video stream is converted is provided. A particular period in a first video stream is repeatedly reproduced to convert the reproduced portion into a second video stream in real time. At that time, the user checks the image quality after conversion on a preview screen and sets a desired conversion parameter. A local decode image is output to the preview screen. Thus, the circuit configuration is simplified. | 08-28-2008 |
20090028447 | IMAGE COMPRESSION METHOD AND IMAGE PROCESSING APPARATUS - When a motion image is to be compressed, the present invention divides a high-resolution still image into image segments to perform a motion image encoding process on each image segment. In this instance, the importance of each image segment and the relativity of each image segment with another image segment are computed. The image segments are then aligned in the order of importance to determine a picture type for motion image encoding in accordance with the computed relativity. Encoding is performed in accordance with a determined encoding sequence and picture type. Further, the rate control bit allocation amount for motion image encoding is increased for highly important image segments. Therefore, the present invention makes it possible to exhibit a high overall image compression efficiency while avoiding image quality deterioration in an important portion of a still image by using a motion image compression technology for still image compression. | 01-29-2009 |
20090034625 | Image Decoder - The present invention relates to an image decoder which implements high speed image decoding with a low cost and simple configuration. By a stream dividing module, an input video stream is divided in units of frames as a plurality of frame rows for distribution. Each of plural decoders generates decoded images by decoding a distributed frame row. Of the decoded images generated by the decoders, reference images to be referred to when a subsequent frame is decoded is stored in a reference image frame memory. A timing control module receives information about stream distribution from the stream dividing module and controls the respective timings of decoding frames distributed to the decoders. | 02-05-2009 |
20090232471 | Information Recording Apparatus - An information recording/reproducing apparatus capable of simplifying settings of a scene breakpoint includes a voice recognition unit and a control unit. At a timing when the voice recognition unit extracts a feature during recording, the control units sets a scene breakpoint and generates a thumbnail at the same time. During reproduction, the thumbnail and voices when the feature was extracted are output at the same time. | 09-17-2009 |
20090297051 | Image Processing Apparatus - An image processing apparatus is configured to have units for compressing and expanding image data and an arbitrating unit for arbitrating control units for executing image processing so that the compressing and expanding units are located between the arbitrating unit and the control units respectively. The apparatus further includes the circuits for compressing and expanding the image data in a reversible manner and a nonreversible manner so that the compressing and expanding manner may be switched according to the image processing condition. When treating a large amount of image data, this configuration makes it possible to reduce the number of accesses to memory and make effective use of a bandwidth, thereby being able to reduce the power consumption. Since the bandwidth is reduced and the random access to memory is made possible, more image processing capabilities may be provided so that the operability of this apparatus is enhanced. | 12-03-2009 |

A refreshing area in which image refreshing is performed by intra coding is established. The refreshing area is shifted in an equal increment every frame such that the refreshing area traverses through the whole frame periodically. Where a macroblock that have passed through the refreshing area is interframe coded, a motion compensation vector of the macroblock is selected such that an image which has passed through the refreshing area is referenced. | 09-29-2011 |
