Abstract
The present invention relates to an image pick-up apparatus having a focus detection mechanism capable of improving an AF speed at low costs and in a space-saving way without adding any new mechanism or optical system and ensuring an accurate focus adjustment and capable of preventing a picture-taking image quality being deteriorated. An image pick-up device of the image pick-up apparatus of the present invention has a focus detection area and image pick-up area and, since no image data is obtained at the focus detection area, interpolation processing is done with image data of a peripheral image pick-up area. In the case where a color filter is provided in the image pick-up area, interpolation processing is done with image data of an image pick-up area and image data of a peripheral area.
