PROBLEM TO BE SOLVED: To suppress influence of a difference of a mounting state of an image data processing device on a characteristic of its output signal. SOLUTION: A characteristic adjustment circuit 48 formed in a first reconfigurable device 38 allows the circuit configuration to be changed in accordance with the operation of a user, and its output characteristic to be changed. The characteristic adjustment circuit 48 includes, for instance, a buffer amplifier. By changing a connection state of a peripheral element of the buffer amplifier, an element constant of the peripheral element or the like, the output characteristic of the characteristic adjustment circuit 48 to a signal transmission line 40 is adjusted. Each circuit configuration of the characteristic adjustment circuit 48 is specified by candidate data stored in a circuit configuration memory. A plurality of candidate data specify connection states, element constants and the like different from one another for the peripheral element of the buffer amplifier. Thus, the characteristic adjustment circuits 48 configured based on the candidate data different from one another have output characteristics different from one another with respect to the signal transmission line 40.
