ABSTRACT:
In a camera system effective use of a single microcomputer for both automatic exposure control and automatic focus control is made possible by designing the microcomputer so that it repeats calculation for the automatic exposure control during time period for charge accumulation in a CCD focus detection sensor and during lens focusing movement and so that it performs calculation for the automatic focus control while interrupting the calculation for the automatic exposure control upon the ending of the charge accumulation in the CCD focus detection sensor and upon shifting of the lens by an amount predetermine based on the result of the calculation for the automatic focus control.
