Description

本発明の一実施形態の撮像装置は、被写体を撮影して映像信号を出力する撮像手段と、前記被写体の移動方向を予測する予測手段と、振れ検出手段から出力された振れ信号に基づいて像振れを補正する第１の補正を実行するための補正部材を駆動して前記第１の補正を実行する機能を備えるとともに、前記予測された被写体の移動方向に応じて、前記補正部材を駆動させることで、撮影画角の前記被写体が移動する方向の空間を空ける第２の補正を実行する制御手段とを備える。 Imaging device according to an embodiment of the present invention includes an imaging means for outputting a video signal by photographing a subject, and estimating means for estimating a moving direction of the previous SL subject, on the basis of the shake signal output from the shake detecting means The correction member for driving the first correction for correcting the image blur is provided to perform the first correction, and the correction member is driven according to the predicted moving direction of the subject. Control means for executing a second correction for making a space in the direction of movement of the subject at the shooting angle of view.
