Abstract
When an image of a subject formed by an optical system is picked up using an image pickup device, charges obtained upon receiving light for the subject image are accumulated with a time difference for each scan line in the image pickup device. Concurrently, a characteristic of the optical system is modified to change a distance to the subject at which the image pickup device is in focus, for each horizontal scan line.
Claims12
An image pickup apparatus comprising:
- an image pickup device taking and converting a subject image formed by an optical system into a video signal;
- an optical adjustment section adjusting the optical system;
- and
- a control section generating one image data based on the video signal for the subject image captured by taking an image of one or a plurality of consecutive first line areas on horizontal scan lines in the image pickup device when the optical system is subjected to a first adjustment, and the video signal for the subject image captured by taking an image of a second line area adjacent to the first line area when the optical system is subjected to a second adjustment different from the first adjustment.
