Abstract
The image pickup apparatus includes an image production unit producing an image by using an output signal from an image pickup unit, a size detection unit detecting a size of a specific object in the image, a storage unit storing a target value of the size of the specific object, a control unit performing auto zoom control that automatically provides a zoom operation to make the size of the specific object equal or closer to the target value, and a position detection unit detecting a position of the specific object in the image. The control unit controls, in the auto zoom control, a speed of the zoom operation depending on the position of the specific object detected by the position detection unit. The apparatus can prevent easy disappearance of the specific object from the image when the auto zoom operation is performed.
