ABSTRACT:
In an electronic still camera apparatus wherein an image of an object is incident on an image pickup surface of a CCD through an optical lens, the object image passed the optical lens is divided into a portion entering the CCD and a portion entering a two-dimensional PSD. The two-dimensional PSD detects a center of gravity of a light distribution of the object image, and a detection signal is supplied to a deviation detector comprising a sample-hold circuit and a differential amplifier. The deviation detector stores the detection signal at the time of start of image pickup, and the differential amplifier compares the stored signal and a detection signal output from the PSD during image pickup. A deviation detection signal corresponding to the comparison result is output. On the basis of the deviation detection signal, at least one of the optical lens and the CCD is moved in a direction perpendicular to the optical axis of the optical lens so as to reduce the deviation of the center of gravity of the light distribution to zero.
