Abstract
Images are photographed by focus bracket photography at an in-focus position of a main subject and at focal positions followed and preceded by the in-focus position. The images are synthesized so as to obtain a blur-emphasized image in which areas desired to be blurred are appropriately blurred.
Claims15
An image pickup apparatus comprising:
- an automatic in-focus position determination device which determines an in-focus position of a main subject on the basis of image data;
- a focus bracket photography device which obtains a plurality of images by successively photographing images while discretely moving a focal position by a predetermined moving amount;
- a focal position control device which controls the focal position, so as to include the in-focus position of the main subject determined by the automatic in-focus position determination device and focal positions followed and preceded by the in-focus position;
- an image synthesis device which synthesizes the plurality of images photographed by the focus bracket photography device, including an image photographed at the in-focus position of the main subject and images photographed at the focal positions followed and preceded by the in-focus position of the main subject;
- and
- a recording device which records an image obtained by the image synthesis device on a recording medium.
