To provide an imaging apparatus and a control method thereof capable of achieving a satisfactory image quality while preventing increase of read-out time for acquiring a focus detecting signal.SOLUTION: The imaging apparatus includes: imaging means that has at least a first mode and a second mode; and control means that performs a read-out operation on a first line in the first mode, and performs a read-out operation on a second line in the second mode and in a mode difference from the second mode. The read-out operation in the first mode made on the first line is carried out in a first read-out period; the read-out in the second mode made on the second line is carried out in a second read-out period; and the read-out in the mode difference from the second mode made on the second line is carried out in a third read-out period. The length in the first to third read-out periods are equal to each other.SELECTED DRAWING: Figure 10 【課題】焦点検出用の信号の取得のための読出し時間の増大を抑制しつつ、良好な画質を得ることが可能な撮像装置及びその制御方法を提供する。【解決手段】第１のモードと第２のモードとを少なくともとり得る撮像手段と、第１の行に対しては第１のモードでの読み出しを行い、第２の行に対しては第２のモードでの読み出しと第２のモードとは異なるモードでの読み出しとを行う制御手段であって、第１の行に対して行われる第１のモードでの読み出しは第１の読み出し周期において行われ、第２の行に対して行われる第２のモードでの読み出しは第２の読み出し周期において行われ、第２の行に対して行われる第２のモードとは異なるモードでの読み出しは第３の読み出し周期において行われ、第１から第３の読み出し周期の長さが互いに等しい制御手段とを有している。【選択図】図１０
