A system control circuit 26 monitors a drive of a light emitting diode (LED) driving circuit 21 and a charge coupled device (CCD) driving circuit 23, a motor 30 as a function executing unit in a capsule endoscope is driven at a timing for an arbitrarily predetermined period different from a lighting period in which the system control circuit 26 lights a LED 20 and an imaging period in which a CCD 22 captures an intra-subject image, and interference for an image caused by a drive of the motor is prevented. As a result, the function executing unit in the capsule endoscope is driven at an arbitrarily predetermined timing, and image collection and image transmission inside the subject is properly performed.
