An automatic focus adjusting apparatus of a camera comprises three CCD sensors receiving light from an object, a focus detecting apparatus for outputting a focus signal indicative of the focusing state of a photographic lens based on output data from the respective CCD sensors, a calculating apparatus for calculating an amount of driving the photographic lens based on the focus signal, a selector for selecting one of the three CCD sensors, a correcting apparatus for correcting the amount of driving calculated based on the output data from the selected CCD sensor, and a driving apparatus for driving the photographic lens to an in-focus position based on the corrected driving amount. An error in foucs detection incidental to the driving of the lens can be corrected based only on the data from one CCD sensor selected by a selector, so that the focusing error on a moving object can be eliminated in a simple manner.

An automatic focus adjusting apparatus of a camera, comprising: (a) a plurality of photoelectric converting means receiving light from an object, each of said photoelectric converting means having a plurality of light receiving portions and a plurality of charge accumulating portions for accumulating charges generated in said light receiving portions; (b) accumulation controlling means for controlling time of charge accumulation in each said photoelectric converting means; (c) focus detecting means for detecting an in-focus state of a photographic lens based on outputs from said photoelectric converting means to output a focus signal; (d) calculating means for calculating an amount of driving said photographic lens based on said focus signal; (e) selecting means for selecting one photoelectric converting means out of said plurality of photoelectric converting means, a focusing error being generated when said photographic lens is moved during said time of charge accumulation of the photoelectric converting means selected by said selecting means; (f) correcting means for correcting the amount of driving of the photographic lens calculated based on said focusing error; and (g) driving means for driving said photographic lens based on said corrected amount of driving the photographic lens.
