20080309775 | Information Recording/Reproducing Apparatus - A video camera is provided not only with means for receiving any general captured images but also with means for receiving images from any other video input source. The video camera is also provided with an image input arbitration section that captures, after arbitration, video data coming from these two input means, and stores the resulting data into a memory. As such, when the video input source is a video output terminal of a car navigation system, the screen of the car navigation system, i.e., map information, can be stored in a memory together with a user's captured image. When the video camera is used for monitoring, data capturing into a memory is also enabled when the video input source is a medium already carrying therein map image data, e.g., USB flash memory and SD card, and means for reading the map image data from the medium. The data in the memory is subjected to a process of compression and encoding as moving images so that the image of position information and the user's captured image can be processed as a set of moving images. This accordingly enables to provide a system and method for recording and reproducing a set of moving images of the combination of an image of position information and a user-captured image with no need for a complicated process. | 12-18-2008 |
20090016437 | INFORMATION PROCESSING APPARATUS - During re-encoding, the picture type before frame-by-frame decoding and the picture type during re-encoding are matched thus enhancing an image quality during the re-encoding operation. Further, by making variable the data volumes that need to be matched between picture information before decoding and picture information during re-encoding, it is possible to realize re-encoding of optimal processing volumes (volumes of picture information that need to be matched in units of frame) for a variety of systems. Further, during re-encoding, the bit volume information used in decoding is used by the encoding unit. The encoding unit uses this bit volume information by combining the bit volume information with the bit allocation target value or I, P, B picture used during re-encoding and performing arithmetic operations on the bit volume information-based bit allocation target value. | 01-15-2009 |
