FRAME-SHIFT DETECTING DEVICE AND A VIDEO-RECORDING APPARATUS |
摘要 |
<p>A frame-shift detecting device includes: a movement-vector detecting portion (4) determining a movement-vector between image frames by comparing a preceding image frame with a current image frame during image taking; and a frame-shift detecting portion (9) for summing up horizontal and vertical components of the movement-vector, separately in order to detect a shift-direction or shift-quantity of the image-pickup frame from the start of counting operation. A video recording apparatus includes: a video recording portion (7) for recording image frames during image taking; a movement-vector detecting portion (4); and a frame-shift detecting portion (9), and the video recording portion records a first video frame at the start of counting operation and a second video frame at the time when the frame-shift detecting portion detects that the image pickup frame has been shifted by a specific shift distance. <IMAGE></p> |
