Description

本発明は、撮像装置、その制御方法及びプログラムに関する。   The present invention relates to an imaging apparatus, a control method thereof, and a program.

本発明は上記のような点に鑑みてなされたものであり、被写体検出精度の低下を抑制できるようにすることを目的とする。   The present invention has been made in view of the above points, and an object of the present invention is to suppress a decrease in subject detection accuracy.

本発明の撮像装置は、互いに異なる波長の光線に対応する複数のカラーフィルタを備えた第１の撮像素子と、前記複数のカラーフィルタのそれぞれに対応する信号を所定の比率で加算する加算手段を備え、前記加算手段は、前記第１の撮像素子の第１の領域と第２の領域で、前記所定の比率を変更するものであって、前記第１の領域と前記第２の領域は一部が重複することを特徴とする。   An image pickup apparatus according to the present invention includes a first image pickup device including a plurality of color filters corresponding to light beams having different wavelengths, and an adding unit that adds signals corresponding to each of the plurality of color filters at a predetermined ratio. And the adding means changes the predetermined ratio between the first area and the second area of the first image sensor, and the first area and the second area are equal to each other. It is characterized by overlapping parts.

本発明によれば、被写体検出精度の低下を抑制することができる。   According to the present invention, it is possible to suppress a decrease in subject detection accuracy.
