An image processing apparatus includes a receiving mechanism configured to receive a request, from at least one different image processing apparatus connected via a network, for transmission of a codestream generated in a way such that image data is divided into at least one region, each region being hierarchically compressed and stored in the image processing apparatus, a decomposing mechanism configured to decompose a codestream and retrieve the codestream in a component unit, an extracting mechanism configured to extract a target region from the codestream, a primary priority assigning mechanism configured to assign priority to the target region extracted by the extracting mechanism, and a primary transmitting mechanism configured for transmission of the codestream, decomposed in a component unit corresponding to the target region, to the different image processing apparatus requesting transmission of the codestream based on the priority assigned by the primary priority assigning mechanism.

Method, program and apparatus for image processing capable of effectively performing image transmission, and a medium storing the program

There are provided a data recording medium, a reading device for reading the data recording medium, a recording device for reading the data recording medium and recording data to other media, and methods thereof able to prevent forgery without comparing visible information and data stored in a built-in electronic circuit chip. The reading device is for reading a data recording medium including a sheet portion visibly printed with an image and a data storage unit recorded with control data. The reading device comprises a first reading unit adapted to optically read the image on the sheet portion, a second reading unit adapted to read the control data including read permission data indicating whether reading of the image is permitted, a determination unit adapted to determine whether reading of the image by the first reading unit is permitted based on the read permission data obtained by the second reading unit, and a controller adapted to control the first reading unit based on the determination by the determination unit.
