ABSTRACT:
A shakeproof camera includes a focus detection circuit for detecting a focus state from an image pickup signal output from an image pickup element, a luminance detection circuit for detecting a luminance from the image pickup signal, a shake detection circuit for detecting a shake vector of an image from the image pickup signal, and a control circuit for fetching outputs from the above detection circuits and performing focus control, exposure control, and shakeproof control. The detection circuits outputs the detection results during a vertical blanking period. The control circuit preferentially performs an arithmetic operation for shakeproof control on the basis of an output from the shake detection circuit and then performs other control operations.
