摘要： A next input image selector 8 specifies a time at which an input image to be processed next is to be input immediately after finishing an encoding of one image. An input video capture 1 obtains an image of which input time has been specified and sends this image to an input image information detector 2. The input image information detector 2 makes a decision as to whether or not the input image is an image to be processed based on an image variance between this input image and an input image processed immediately before stored in a frame memory 3. If this decision is negative, an input image re-selector 4 re-selects an image to be processed, and if the decision is affirmative, this input image is sent as an image to be processed to a target output bits setter 5 and a motion predictor 11. An output bits controller 6 determines a quantizing level of a quantizer 14 from target output bits and actual output bits obtained from an encoder 15. A video encoder capable of encoding images in uniform picture quality with realtime processing feature can be provided.

摘要： A variance between sequential video pictures is extracted, and then, a GOP boundary position is decided based on inter-frame variance information. Furthermore, simple motion estimation is carried out with respect to video pictures inside one GOP. If a motion variation between the video pictures is large, a small predictive frame interval is taken; to the contrary, if the motion variation is small, a large predictive frame interval is taken. The simple motion estimation is carried out between two downscaled feature planes at a timewise fixed interval with respect to a video picture which is discriminated to be an interlaced video picture, wherein a motion compensatory prediction error at that time is output as image variance information. If the image variance is small, coding is conducted by a frame structure; to the contrary, if the image variance is large, the coding is conducted by a field structure. With the above-described processing, it is possible to provide a video coding apparatus for deciding a GOP size and the predictive frame interval according to the feature of the input video picture, and another video coding apparatus for adaptively switching the coding by the frame/field structures according to the feature of the input video picture.

摘要： The present invention intends to provide a classification apparatus for broadcasted sport videos for classifying various scenes constituting a sport video, depending on the importance level without being limited to any particular sport video by using visual and audio features. A sport video classification processing portion determines and classifies a play scene, a close-up shot and the like using an audio and a color feature extracted from motion picture data. Because the determination of the most frequent color can be changed adaptively for each inputted sport video, it is not necessary to determine any particular color to the most frequent color previously.

摘要： A coding parameter extracting unit extracts predictive-coded mode information, motion vectors, and coded transformed coefficients from video-signal-demultiplexed information. An abrupt scene change judging unit uses a characteristic that scenes change greatly before and after an abrupt scene change, to classify blocks on the basis of the predictive-coded mode information among the compressed moving picture data, so that an abrupt scene change is detected. A special effect judging unit detects dissolve from motion characteristic values calculated from the values of motion vectors, predictive-coded picture characteristic values derived from coefficients on frequency domains in blocks, and the number of blocks each having a motion vector that is larger than a threshold; and detects wipe by motion characteristic values calculated from the values of motion vectors, and predictive-coded picture characteristic values derived from coefficients on frequency domains in blocks. According to this architecture, scene changes including special effects such as dissolve or wipe can be detected at high speed and high accuracy by a processing which is far less than that of the prior art.
