  • Publication number: 20140337416
    Abstract: The invention relates to an image processing system in which a client apparatus transmits RAW image data to a server apparatus, receives a result developed by the server apparatus, and displays onto a display area. The client apparatus reduces the RAW image data to a size suitable to display, transmits to the server apparatus, and requests a development processing. At this time, the client apparatus also starts a transmission processing of original RAW image data to the server apparatus. While making adjustment of the development processing to reduced RAW image data, the client apparatus and the server apparatus also execute a transmission and reception processing of the original RAW image data in parallel therewith. After the development processing of the reduced RAW image data, if there is a request from the client apparatus, the server apparatus also executes the development processing of the original RAW image data in a manner similar to the reduced RAW image data.

  • Patent number: 7809186
    Abstract: Provided herein is an image processing apparatus comprising: input means for inputting image data, which is obtained by digitalizing an image signal that has been converted from light from an object to an electric signal by an image sensor, and performing no compression or lossless compression; image processing parameter input means for inputting a parameter to be employed in image processing on the image data executed by a user; image processing means for performing luminance-related processing or chrominance-related processing on the image data in accordance with the image processing parameter inputted by the image processing parameter input means; and storage means for storing an intermediate result for each of the luminance-related processing and the chrominance-related processing. By virtue of storing the intermediate results, this invention contributes not only to high-speed RAW image data development processing, but also to a reduced image processing load and increased processing speed.

  • Patent number: 7620271
    Abstract: The invention displays an image that conforms to an editing parameter set by the user and, depending upon the editing parameter requested, shortens the time required for the image to be displayed, thereby enhancing usability. To achieve this, the invention has a processing parameter input unit for inputting an editing-related parameter such as sharpness. If an image data file to be edited is read in from an image file storage unit, photographic condition information within the file is analyzed and the information obtained by analysis is compared with a parameter that has been set. If the two agree, then a display is presented based upon processed image data within the image file. If the two do not agree, then unprocessed image data within the same file is subjected to image processing in accordance with the set parameter and the processed image is displayed.
