摘要： PROBLEM TO BE SOLVED: To provide a technique capable of playing plural moving images captured in parallel under plural mutually different image capturing conditions at a predetermined frame rate while suppressing degradation of image quality.SOLUTION: An image capturing apparatus selects one of image capturing conditions used for image capturing as a reference condition when a total image capturing time of one frame in the each image capturing condition used for image capturing is longer than one frame period at a predetermined frame rate, captures images at the predetermined frame rate in the reference condition, and captures images at a frame rate lower than the predetermined frame rate in the other image capturing conditions. A playback system allows a user to select a playback moving image that is a moving image to be played from captured moving images, detects a motion between frames of a moving image captured in the reference condition when the image capturing condition of the playback moving image is not the reference condition, and converts the frame rate of the playback moving image to the predetermined frame rate by generating an interpolation frame based on the detected motion.
摘要翻译：要解决的问题：提供一种能够在抑制图像质量劣化的同时以预定帧速度在多个相互不同的图像捕获条件下平行拍摄的多个运动图像的技术。解决方案：当用于图像捕获的每个图像捕获条件中的一帧的总图像捕获时间长于一个帧周期时，图像捕获设备选择用于图像捕获的图像捕获条件之一作为参考条件预定帧速率，在参考条件下以预定帧速率捕获图像，并且在另一图像捕获条件下以低于预定帧率的帧速率捕获图像。回放系统允许用户从拍摄的运动图像中选择作为要播放的运动图像的回放运动图像，当回放运动图像的图像拍摄条件为不是参考条件，并且通过基于检测到的运动生成插值帧来将播放运动图像的帧速率转换为预定帧率。版权所有（C）2012，JPO＆INPIT
