1. An image pickup apparatus comprising:
- an image-taking optical system, an image pickup device which photoelectrically converts an object image formed by the image-taking optical system and outputs pixel signals, a signal processing circuit which generates image data by processing the pixel signals outputted from the image pickup device, a movement judging circuit which judges the presence or absence of movement in the object image on the image pickup device based on the pixel signals from the image pickup device, and a control circuit which controls the drive of the image pickup device, wherein the control circuit drives the image pickup device in a first mode in which pixel signals are outputted from all lines of the image pickup device when the movement judging circuit judges that the object image on the image pickup device has no movement, and drives the image pickup device in a second mode in which pixel signals are outputted from a part of all lines of the image pickup device when the movement judging circuit judges that the object image has movement.

Abstract
The present invention discloses an image pickup apparatus which achieves easy image composition adjustments and image-taking angle changes. The image pickup apparatus of the invention comprises a signal processing circuit which generates image data from the image pickup device, a movement judging circuit which judges the existence of movement in an object image based on the pixel signals, and a control circuit which controls the drive of the image pickup device. The control circuit drives the image pickup device in a first mode in which pixel signals are outputted from all pixels of the image pickup device when the movement judging circuit judges that the object image has no movement, and drives the image pickup device in a second mode in which pixel signals are outputted from a part of all pixels of the image pickup device when it is judged that the object image has movement.
