Abstract: An image processing system includes an image processing apparatus and a decryption server interconnected via a network. When a portable recording medium having an encrypted target file and access information to access a decryption server that decrypts this encrypted target file, recorded therein, is connected to a connector of an image processing apparatus, the image processing apparatus reads out the encrypted target file and the access information from the portable recording medium connected thereto, accesses the decryption server according to the access information, then transmits the encrypted target file to the decryption server. The decryption server decrypts the encrypted target file received therefrom, and returns it to the image processing apparatus. The image processing apparatus executes processing on the decrypted target file that is returned therefrom.

Abstract: Radiation image data obtained by an imaging unit in a radiation irradiation state is stored. Reference image data obtained by the imaging unit in a radiation non-irradiation state is stored. Reduced radiation image data and reduced reference image data as reduced image data of the radiation image data and the reference image data are generated. Offset correction processing is executed between the radiation image data and the reference image data. After output of the reduced radiation image data and the reduced reference image data to the external device is ended, offset-corrected radiation image data is output to an external device.

Abstract: To efficiently generate image data by using correction data. First offset data is obtained in advance for each of a plurality of imaging times, and is stored in a second image storage unit. The imaging time requested by a user is selected from the plurality of imaging times by a control unit, and an object is shot in the selected imaging time so as to store image data in a first image storage unit. A correction processing unit offset-corrects the image data by using first offset data corresponding to the selected imaging time and outputs first image data (preview image). In parallel with an output of the first image data, an imaging operation without irradiation is performed to have second offset data on approximately the same conditions as actual imaging obtained by the control unit, and the image data is offset-corrected by using the obtained second offset data so as to output second image data.

Abstract: Image sensing radiation detection pixels of m (columns)×n (rows) are divided into, e.g., 72 pixel regions. Image sensing radiation detection pixels belonging to one pixel region are connected to the same read TCP and driving TCP. For example, three regions (AEC radiation detection regions) of the 72 pixel regions have a plurality of AEC radiation detection pixels. An AEC radiation detection pixel has a TFT sensor. Spare wiring lines for the AEC radiation detection pixels are arranged at two side portions of each read TCP. Each spare wiring line is connected to a predetermined circuit in a read device to connect the AEC radiation detection pixels to the predetermined circuit so that the AEC circuit is operated.

Abstract: The invention relates to an image sensing apparatus and method which form an image by using radiation including visible light, X-rays, and the like (which is generically called light in the invention), and also relates to a -one- or two-dimensional image sensing apparatus such as a facsimile apparatus, a digital copying machine, a still camera, or a radiation image sensing apparatus, and an image sensing method. This image sensing apparatus uses a photo-electric conversion device. The image sensing apparatus has an image sensing means including a plurality of photo-electric elements arranged one- or two-dimensionally to obtain image information with a high S/N ratio by solving the problem that errors contained in the photographic output cannot be completely corrected because of the differences between the conditions set to obtain data to be used for correction and the conditions set for actual photographing operation.
