Description

本発明は、撮像装置、及びその制御方法とプログラムに関し、特に動画撮影中の動画像の質を向上させる技術に関するものである。 The present invention relates to an imaging apparatus, a control method therefor, and a program, and more particularly to a technique for improving the quality of a moving image during moving image shooting.

本発明は、かかる従来の課題に鑑みてなされたものであり、動画撮影中の動画像の質を向上することを可能とする撮像装置、及びその制御方法とプログラムを提供することを目的とする。 The present invention has been made in view of such conventional problems, and an object thereof is to provide an imaging apparatus capable of improving the quality of a moving image during moving image shooting, and a control method and program thereof. .

前記課題を解決するため、本発明にあっては、撮像手段に設定可能な撮像フレームレートを第１のフレームレート、前記撮像手段が前記第１のフレームレートの撮像フレームレートで撮像した画像を前記第１のフレームレートと同一の記録フレームレートで記録する時の前記撮像手段の撮像動作における撮像感度を第１の感度、とした時に、前記撮像手段が前記第１のフレームレートで撮像した画像を前記第１のフレームレートより低速の第２のフレームレートで合成記録する際のフレーム合成数と前記撮像手段の撮像動作における撮像感度を、フレーム合成数＝第１のフレームレート÷第２のフレームレート；撮像感度＝第１の感度÷フレーム合成数；として制御する制御手段、を備えたことを特徴とする。 In order to solve the above-described problem, in the present invention, an imaging frame rate that can be set in the imaging unit is a first frame rate, and an image captured by the imaging unit at an imaging frame rate of the first frame rate is When the imaging sensitivity in the imaging operation of the imaging unit when recording at the same recording frame rate as the first frame rate is the first sensitivity, the image captured by the imaging unit at the first frame rate The number of combined frames when combining and recording at a second frame rate that is slower than the first frame rate and the imaging sensitivity in the imaging operation of the imaging means are: frame combined number = first frame rate / second frame rate. Control means for controlling: imaging sensitivity = first sensitivity / number of frames combined;

本発明によれば、動画撮影中の動画像の質を向上することが可能となる。 According to the present invention, it is possible to improve the quality of a moving image during moving image shooting.
