A method for providing image blur information is applied to a photographing mode of image capturing apparatus of which a shooting shutter speed is greater than a safe shutter speed, the method comprising the steps of: capturing a long exposure image in the shooting shutter speed and a short exposure image which is smaller than or equal to the safe shutter speed, in order to search correspondingly a plurality of characteristic positions in the long exposure image and the short exposure image, and then comparing the characteristics on the relative characteristic positions between the long exposure image and the short exposure image to produce a comparing result upon which a further operation is performed to define a degree of image blur. Thus, the present invention can achieve the purpose of providing image blur information for the long exposure image when the image capturing apparatus captures the long exposure image.
