Patent ID: 8675095

Claim:
An image data processing system comprising: a first device that includes a data output unit, an image file generation unit, and a transfer processing unit; and a second device that includes a specification data generation unit; wherein the first device transfers image data of an independent image in an image file, which stores a plurality of independent images, to the second device; the data output unit outputs combined miniaturized image data that contains a plurality of miniaturized images to the second device in response to a transfer request for image data, the combined miniaturized image data is generated by combining the plurality of miniaturized images and is used to show the plurality of miniaturized images in a combined state, the plurality of miniaturized images respectively correspond to the plurality of independent images in the image file, and each of the miniaturized images has a smaller data volume than the corresponding independent image; the specification data generation unit generates transfer subject specification data based on the output combined miniaturized image data, and the transfer subject specification data specifies transfer subject image data that corresponds to a transfer subject independent image; the image file generation unit generates a transfer image file storing the transfer subject image data based on the generated transfer subject specification data; the transfer processing unit transfers the transfer image file to the second device; the second device includes: a display capable of showing a list of the miniaturized images; and an external operation unit that is externally operated to specify a miniaturized image corresponding to the transfer subject independent image from the miniaturized images shown on the display in the list; the transfer request for image data provided from the second device to the first device includes size information of the display; the data output unit adjusts the combined miniaturized image data in accordance with the display size information and outputs the adjusted combined miniaturized image data to the second device; and the display adjusts the size of each miniaturized image shown on the display in the list based on the output and adjusted combined miniaturized image data.
