A data reception device includes a wireless communication interface configured to receive imaging data transmitted from a capsule endoscope in which a frame rate of imaging is changeable based on a frame rate-setting value for designating the frame rate and which transmits the imaging data after the imaging by performing the imaging, and to transmit the frame rate-setting value to the capsule endoscope, a storage module configured to store reference image information to be used to specify a part of a living body included in the imaging data, a range-of-interest detection unit configured to detect a range of interest which is a range of the part in the imaging data based on the reference image information, an amount-of-change detection unit configured to detect an amount of change in the range of interest between the imaging data of two different frames, and a frame rate determination unit configured to determine the frame rate-setting value to be transmitted to the capsule endoscope as a value greater than a previously determined frame rate-setting value when the amount of the change in the range of interest exceeds a predetermined reference value, and to determine the frame rate-setting value to be transmitted to the capsule endoscope as a value less than the previously determined frame rate-setting value when the amount of the change in the range of interest is less than the predetermined reference value.
