Image pickup apparatus, image pickup method, program for implementing the method, and storage medium storing the program

摘要

An image pickup apparatus which is capable of accurately detecting a blur of a shot image. AF evaluation values are calculated before and after shooting for recording an image representing the subject image in a recording medium is performed. The correlation between the AF evaluation values calculated before the shooting and the signal indicative of the focus generated after the shooting is determined. It is determined whether the correlation is lower than a first threshold value and higher than a second threshold value.
