<p><P>PROBLEM TO BE SOLVED: To provide a high efficiency coding recorder for carrying out optimum coding processing with a small code amount by controlling coding for each scene. <P>SOLUTION: A database management circuit 108 acquires a correction value of a parameter for controlling the coding processing from a scene information database 104 on the basis of information associated with a genre of a video image being an object of the coding processing obtained by a genre/keyword searching circuit 103, scene characteristic information representing the characteristic of each scene separated by a scene separation circuit 107, on the basis of image characteristic information obtained by an image characteristic calculation circuit 105 from digital image data of the video image, and coding result information associated with a code amount obtained by a code amount control circuit 219 through the application of the coding processing to the digital image data, and a coded parameter correction circuit 109 corrects the parameter in the high efficiency coding recorder 10 on the basis of the acquired correction value. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
