STILL-IMAGE EXTRACTING METHOD AND IMAGE PROCESSING DEVICE FOR IMPLEMENTING THE SAME

摘要

A still-image extracting method is disclosed. Frames of an object are extracted as still images from a moving image stream chronologically continuously captured by a camera. The camera moves relative to the object. First frames are extracted from the moving image stream. Image capture times of the extracted first frames are obtained. Image capture positions of the camera at the image capture times of the first frames are identified based on the first frames. Image capture times of the frames captured at image capture positions spaced at equal intervals are estimated based on both the image capture positions, identified by the first frames, of the camera and the obtained image capture times. Second frames at the estimated image capture times are extracted as frames captured and obtained at image capture positions spaced apart at equal intervals from the moving image stream.

1. A still-image extracting method for extracting a plurality of frames of an object as still images from a moving image stream chronologically continuously captured by a camera, the camera moving relative to the object, the method comprising:
extracting a plurality of first frames from the moving image stream and obtaining image capture times of each of the first frames extracted; identifying image capture positions of the camera at the image capture times of each of the first frames based on the plurality of first frames; estimating image capture times of the plurality of frames captured at a plurality of image capture positions spaced at equal intervals based on both the image capture positions, identified by each of the first frames, of the camera and the obtained image capture times; and extracting, from the moving image stream, second frames at the estimated image capture times as a plurality of frames captured at a plurality of image capture positions spaced apart at equal intervals.
