PROBLEM TO BE SOLVED: To provide a timing detection device, a timing control device, a radio signal receiving device, and a radio signal receiving device for a capsule endoscope, which can detect timing with high accuracy while suppressing an operating frequency.SOLUTION: The timing detection device includes: a first calculation unit 101 that calculates a cumulative addition value of digital frequency adjustment values at predetermined time intervals a second calculating unit 201 for calculating a difference between the cumulative added value and a threshold value of the cumulative added value and a third calculating unit 202 for calculating a second time at which the cumulative value corresponds to the threshold value and which exists within a predetermined time interval on the basis of a first time that is a time at which the cumulative addition value is calculated and the difference.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2019,JPO&INPIT【課題】動作周波数を抑制しつつ精度の高いタイミングの検出をすることができるタイミング検出装置、タイミング制御装置、無線信号の受信装置及びカプセル内視鏡のための無線信号の受信装置を提供すること。【解決手段】タイミング検出装置は、デジタルの周波数調整値の累積加算値を所定の時間間隔で算出する第1算出部101と、累積加算値とこの累積加算値の閾値との差分を算出する第2算出部201と、累積加算値が算出された時刻である第1時刻と差分とに基づいて、累積加算値が閾値に対応し、所定の時間間隔の間に存在する第2時刻を算出する第3算出部202とを備える。【選択図】図2
