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.

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.

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.

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.

Abstract: An image processing apparatus for reproducing a moving image from its encoded data is disclosed. The apparatus includes a decoding unit to decode the encoded data, and a control unit to control the decoding by the decoding unit. The control unit inhibits image reproduction by partial decoding in the decoding unit with respect to the encoded data of a moving image having scalability.

Abstract: An image processing method includes obtaining raw image data of an object by generating the object by an imager that generates an image of the object with color decomposition, decomposing the raw image data into a plurality of color planes such that each of the color planes comprises pixel information of a color pertinent to the color plane, and compressing data of each color plane.

Abstract: An image compressing apparatus divides an image into plural tiles, decomposes each tile into plural sub band by frequency conversion, and conducts bit plane encoding of each sub band for each encoding unit, wherein the image compressing apparatus includes a code discarding unit selectively discarding a code obtained by the bit plane encoding for each encoding unit, and wherein the code discarding unit includes a discard amount setting unit that makes generally even the amount of code discarding in the encoding units that are in mutually adjacent relationship across a tile boundary.

Abstract: An image recording apparatus includes means for recording image data in a recording medium; means for obtaining information for determining a data amount reduction remaining force of image data recorded in the recording medium; means for selecting image data determined to have a large data amount reduction remaining force based on the information obtained by the means for obtaining information, with a priority; and means for performing a data amount reduction process against the image data selected by the means for selecting.

Abstract: In response to a partial codestream truncation command, a partial codestream truncation process unit temporarily truncates a code line of encoded data. The partial codestream truncation process unit can also temporarily truncate the code line frame by frame. In response to an undo command, a restoration process unit restores the encoded data that has temporarily truncated code line. The temporarily truncated frames are included in a group of frames of the moving image. In response to an undo releasing command, a code line discarding unit discards the temporarily truncated code line or frames. The encoded data has a form of JPEG2000 or Motion-JPEG2000.

Abstract: An image processing method carries out a compression process which divides an image into a plurality of divided regions and compresses the divided regions in a state where each of the divided regions are independent of one another, and sets boundaries of the divided regions in order to approximately match boundaries of one or a plurality of image regions which are within the image and have aspect ratios and/or sizes different from those of the image.

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.
