Patent number: 8442383Abstract: An image capturing apparatus selects one of image capturing conditions to be used for capturing images as a reference condition when a total of image capturing time of one frame in each image capturing condition to be used for capturing images is longer than one frame period at a predetermined frame rate, and captures images at the predetermined frame rate under the reference condition, and captures images at a frame rate lower than the predetermined frame rate under the other image capturing conditions. A playback apparatus detects a motion between frames of a moving image captured under the reference condition when the image capturing condition of the playback moving image is not the reference condition, and generates an interpolation frame for interpolating between frames of the playback moving image based on the detected motion.Type: GrantFiled: August 10, 2011Date of Patent: May 14, 2013Assignee: Canon Kabushiki KaishaInventor: Yoshihisa Furumoto
