The present invention relates to when the vibration displacement using a camera image measured camera shake correction method, and its object is analyzed in the camera image when the shake in the camera itself occurs during the vibration displacement measurement using the camera images without any blurring detecting sensor only to correct the direction and the shaking value of the swing, and rapid calculation to reflect the correction value at the time of calculation of the vibration displacement by to produce a vibration displacement of the measurement target object, you can be surely ensure accuracy of the measured vibration displacement It would be to make, and is arranged so that photographed image acquisition step of acquiring successive images of the measurement target object photographed by the camera; Reference image selection step of selecting a first image of the photographing image acquired in a series of image acquisition step based on the image; The reference feature region selection stage of the reference image to select a feature region in the reference image (S ₀₎ selected in the image selection step; And the reference point of the reference image selection step for selecting the points A, B, C in the feature area selection feature region selection stage of the reference image; Standard edge detection step of detecting the edge of the line segment AB and BC connecting the reference points A and B and, B and C selected from the reference point selected in step with the reference image, respectively; Coordinate calculation step of calculating the intersection point of the reference coordinate of the intersection point of the line segment AB and BC based on the edge values ​​calculated by the standard edge detection step; Feature region selection step of comparing the image to select a feature region in the comparison image; Reference point selection step of comparing the image to select the points A, B, C in the feature area selection feature area selection step of the comparative image; And the reference point A and reference point B selected from the selection step of the comparative image, comparing the edge detection step of detecting the edge of the line segment AB and BC connecting B and C, respectively, and; Coordinate calculation step of comparing the intersection of calculating the coordinates of the intersection point of the line segment AB and BC based on the edge values ​​calculated in the comparing edge detection step; Tilt detecting step of comparing compares the image to detect the gradient of the line AB in the feature region of the image; θ _{1 ... n} - displacement value conversion step of the junction using the θ ₀ for converting the displacement of the intersection in the feature region image in comparison to the normal direction; Applying the converted displacement value to the threshold value calculated by the actually measured object, a displacement value and applying step; If the comparison image of the 'i + 1' to check if smaller than 'n', and if 'i + 1' is less than 'n', composed of the remaining comparison image confirmation step of return to the feature region selection stage of the comparison image It is characterized.
