  • Publication number: 20040208380
    Abstract: A system is disclosed for reproducing a moving image encoded into an encoded data stream in accordance with JPEG 2000 that includes a reproduction apparatus and a transmission apparatus. The reproduction apparatus transmits a reproduction condition being set by a setting unit provided therein, the reproduction condition set in accordance with the user's operation, to the transmission apparatus. The transmission apparatus transmits an encoded data stream reconfigured by a reconfiguration unit based on the reconfiguration method determined by a determination unit based on the reproduction condition. When determining the reconfiguration condition, the determination unit may take a traffic condition of a communication channel into consideration. According to the above embodiments, the system does not need to transmit an original encoded data stream via the communication channel but can transmit the reconfigured encoded data stream that contains only encoded data for satisfying a user's requirement.

  • Publication number: 20040131264
    Abstract: An image processing apparatus includes a condition setting unit with which a user sets a post-quantization condition. A partial decoding and decompression unit partially decodes and decompresses coded data according to the post-quantization condition set by the user, thereby reproducing image data the same as that reproduced by decoding and decompressing coded data after post-quantization processing in accordance with the post-quantization condition. An image data displaying unit displays on a display unit the image data reproduced by the partial decoding and decompression unit.

  • Publication number: 20040130570
    Abstract: Upon browsing an image stored in an image data source, coded data used for display of the image is acquired from the image data source. The acquired coded data used for the display is decoded/extended, and the image is displayed on a display unit. A user inputs a direction for saving the image displayed on the display unit via a user interface unit. Coded data for the saving of the image directed by the user is acquired from the image data source, such as by additionally acquiring coded data equivalent to a difference between the coded data for the saving and the coded data used for the display from the image data source, and synthesizing the coded data for the saving from the additionally acquired coded data and the coded data used for the display. The acquired coded data for the saving is saved in a storage unit.

  • Publication number: 20040100654
    Abstract: Efficient utilization of a memory medium is enhanced in an image-processing apparatus, in which encoded data of JPEG 2000 or Motion-JPEG 2000 are stored in the memory medium as a file. File size of the encoded data is adjusted close to, but not to exceed an integer multiple of a memory domain management unit (sector size) of the memory medium. Thereby, a memory domain assigned to the image file in its entirety, or almost in its entirety, is used effectively, improving the efficient utilization of the memory medium.

  • Publication number: 20040095477
    Abstract: An ROI setting apparatus including an ROI recognition unit and an ROI control unit is provided. In one embodiment, the ROI recognition unit contains multiple ROI recognition modules for recognizing an ROI of image data according to various methods to obtain a recognition result. The ROI control unit selects one ROI recognition module out of the ROI recognition modules and sets ROI information based on the recognition result. The ROI recognition module may be selected according to an instruction from a user input via an operation unit, or a scene type selected by a scene selection switch of an image capture unit. The ROI control unit may perform operations such as selecting, enlarging, or reducing the ROI recognized by the ROI recognition module, or changing the ROI recognition conditions according to the respective instructions from the user input via the operation unit.

  • Patent number: 6579083
    Abstract: A mold for producing a fuel cell separator with which a flash, even if it occurs, does not cause a thickness unevenness. The mold includes a plurality of molds 2, 4 and 10, and a fuel cell molding cavity 5 for separator being defined among the molds. At least one of the molds is provided with a flash reservoir cavity 11 which is communicated with the cavity 5. An amount of material in excess of the volume of the cavity 5 is charged, and melted by the application of pressure and heat. The melted material fills up the entire cavity 5, with the excess thereof entering the cavity 11. Since the molds 2 and 10 maintain a direct contact with each other, it is possible to obtain a separator molded with a high accuracy.
