Abstract

In the auto-focus apparatus, a CPU controls an amount of shift of a focus lens system for each sampling when an AF evaluated value is sampled so that the amount of shift is changed according to a number of recording pixels in a CCD. Therefore, even if a CCD having a large number of pixels is utilized the apparatus can perform auto-focusing within a short time.
