Description

本発明は、撮像装置、撮像方法及びプログラムに関し、詳細には、暗い被写体などの撮影において複数の撮影画像を合成することができる撮像装置、撮像方法及びプログラムに関する。 The present invention relates to an imaging apparatus, an imaging method, and a program, and more particularly, to an imaging apparatus, an imaging method, and a program that can synthesize a plurality of captured images in shooting a dark subject or the like .

本発明は、このような問題点に鑑みてなされたものであり、その目的は、明るさなどの状態が変化する被写体（たとえば、チカチカと瞬く星を含む夜空の星々）の撮影において複数の撮影画像を不都合なく合成して撮影できるようにすることにある。 The present invention has been made in view of such a problem, and an object of the present invention is to perform a plurality of shootings in shooting a subject whose state such as brightness changes (for example, stars in the night sky including flickering stars and blinking stars). It is to the so that can be taken by synthesizing without inconvenience images.

本発明に係る撮像装置は、複数の被写体を連続撮影する撮影手段と、前記連続撮影された複数枚の画像を合成出力する画像合成手段と、前記画像合成手段で画像の合成を行う際に、所定の基準に基づいて各画像内に存在する被写体の各々の合成を行うか否かを判定する判定手段とを備えたことを特徴とする。 The image pickup apparatus according to the present invention includes a photographing unit that continuously photographs a plurality of subjects , an image synthesizing unit that synthesizes and outputs a plurality of continuously photographed images, and an image synthesizing unit that combines the images. And determining means for determining whether to synthesize each of the subjects existing in each image based on a predetermined criterion .

本発明によれば、複数の被写体を連続撮影して得られた複数の撮影画像を合成する場合に、所定の基準に基づいて各画像内に存在する被写体の各々を合成すべきか否かを判定するので、例えば明るさなどの状態が変化する被写体であっても合成を支障なく行うことができる。 According to the present invention, when combining a plurality of captured images obtained by continuously capturing a plurality of subjects , it is determined whether or not each of the subjects existing in each image should be combined based on a predetermined criterion. since, Ru can be performed without any trouble synthesis even subject to change conditions such as for example brightness.
