Description
本発明は、撮像装置およびその制御方法に関し、特に、メモリなどに記録した画像データを画像処理する撮像装置に関する。 The present invention relates to an imaging apparatus and a control method thereof, in particular, to an imaging device for image processing the image data recorded in a memory or the like.
そこで、本発明の目的は、連続して複数回の撮影を行って得られた画像データを画像処理する際、画像データ間で明るさおよび色などのばらつきを抑えることができる撮像装置およびその制御方法を提供することにある。 Accordingly, an object of the present invention is to provide an image pickup apparatus capable of suppressing variations in brightness, color, and the like between image data when image processing is performed on image data obtained by performing a plurality of continuous shootings, and control thereof. It is to provide a method.
上記の目的を達成するために、本発明による撮像装置は、露出を変更して連続的に撮影することによって複数枚の画像を取得する撮影モードを有する撮像装置において、前記撮影モードの撮影で取得された複数枚の画像を画像セットとしたとき、当該画像セットのうちで所定の条件を満たす現在画像と、前記画像セットの撮影の前の撮影で取得された過去画像との類似度を判定し、前記類似度に応じた補正量を用いて、前記画像セットに含まれる複数枚の画像に対して画像処理を行うことを特徴とする。 To achieve the above object, an imaging apparatus according to the present invention, an imaging apparatus having an imaging mode for acquiring a plurality of images by continuously photographing by changing the exposure, acquired by shooting the shooting mode When a plurality of images are set as an image set, a similarity between a current image satisfying a predetermined condition in the image set and a past image acquired by shooting before shooting the image set is determined. The image processing is performed on a plurality of images included in the image set using a correction amount corresponding to the similarity .
本発明による制御方法は、露出を変更して連続的に撮影することによって複数枚の画像を取得する撮影モードを有する撮像装置の制御方法において、前記撮影モードの撮影で取得された複数枚の画像を画像セットとしたとき、当該画像セットのうちで所定の条件を満たす現在画像と、前記画像セットの撮影の前の撮影で取得された過去画像との類似度を判定し、前記類似度に応じた補正量を用いて、前記画像セットに含まれる複数枚の画像に対して画像処理を行うことを特徴とする。 The control method according to the present invention is a method for controlling an image pickup apparatus having a shooting mode in which a plurality of images are acquired by continuously shooting while changing exposure, and a plurality of images acquired by shooting in the shooting mode. Is set as an image set, a similarity between a current image satisfying a predetermined condition in the image set and a past image acquired by shooting before shooting the image set is determined, and according to the similarity Image processing is performed on a plurality of images included in the image set using the correction amount.
続いて、ＨＤＲ撮影が行われて、２コマ目〜４コマ目が得られる。いま、２コマ目が適画像、３コマ目がアンダー画像、そして、５コマ目がオーバー画像であるとする。図示のように、過去コマ（１コマ目）と適画像（２コマ目）との類似度ＳｉｍＡは、ＳｉｍＡ＞Ｔｈ１Ａであるので、図８に示すステップＳ３１０において、ＨＤＲ撮影（適画像）における補正量Ａとして１コマ目の補正量Ａが引き継がれて最終補正量Ａとされる。 Subsequently, HDR shooting is performed to obtain the second to fourth frames. Assume that the second frame is a suitable image, the third frame is an under image, and the fifth frame is an over image. As shown in the figure, the similarity SimA between the past frame (first frame) and the appropriate image ( second frame) is SimA> Th1A. Therefore, in step S310 shown in FIG. 8, correction in HDR shooting (appropriate image) is performed. As the amount A, the correction amount A of the first frame is taken over and becomes the final correction amount A.
