Abstract
An image pick-up device and a chromatic aberration correcting method are provided in which a satisfactory correction processing can be performed even when the image pickup device, such as a camera, simultaneously performs shake correction. An output signal from a camera-signal processing circuit is selected by a selector switch and is supplied to a chromatic aberration correcting unit. An angular velocity due to the camera shake is detected using sensors and the detected signal is supplied to a camera shake correcting vector calculating unit. A driving state of a camera lens is supplied to a conversion-ratio calculating unit. An optical axis centered shift vector of camera lens is obtained from the camera shake correcting vector and is supplied to the correcting unit. Accordingly the picture-quality deterioration caused in the miniaturized camera lens can be compensated by processing the captured image signal, and also a satisfactory correction processing can be performed even when the camera shake correction is performed simultaneously.
