Patent ID: 8320754

Claim:
An electronic camera, comprising: an imager having an imaging surface which captures a scene through a zoom lens and a focus lens; a first changer which changes a distance from the zoom lens to the imaging surface in response to a zoom operation by an operator; a second changer which executes a process of changing the distance from the focus lens to the imaging surface by referring to a tracking curve, in parallel with a changing process of said first changer; a limiter which limits a changing process of said second changer when a changing amount by said first changer has exceeded a threshold value; an adjustor which adjusts the distance from the focus lens to the imaging surface into a distance equivalent to a focal point based on an image outputted from said imager after the zoom operation has been cancelled; and an updater which updates the tracking curve to be referred to by said second changer based on the distance defined by said first changer and the distance defined by said adjuster, wherein said limiter includes an accumulator which accumulates the changing amount in parallel with the changing process of said first changer, and a comparer which compares an accumulated value calculated by said accumulator with the threshold value.
