Abstract
An electronic image pick-up apparatus acquires auto-focus data from each of an AF sensor module and an image sensor disposed in conjugate positions in a test mode, stores data on any relative deviation between those items of auto-focus data and drives a photographic lens based on the data of relative deviation of auto-focus in a normal mode.
