Abstract
An image sensing apparatus performs a plurality of times of image sensing on a subject, superpose-combines the obtained plurality of subject images into one subject image. The apparatus has an image sensing unit that converts a subject optical image into an electric signal, an optical unit that changes a view angle, and a change unit that changes the position of the optical unit by a predetermined amount so as to widen the view angle by a predetermined amount, prior to the plurality of times of image sensing.
Claims24
An image sensing apparatus which performs a plurality of times of image sensing on a subject, superpose-combines a plurality of subject images obtained by the image sensing into one subject image, comprising:
- an image sensing unit that converts a subject optical image into an electric signal;
- an optical unit that changes a view angle;
- and
- a change unit that changes a position of said optical unit so as to widen the view angle by a predetermined amount, prior to said plurality of times of image sensing on the subject,
- wherein the image sensing apparatus is operative in a mode to perform image sensing on the subject once and obtain one subject image, and if a mode to perform a plurality of times of image sensing on the subject then superpose-combine a plurality of subject images obtained by the image sensing into one subject image is set, said change unit changes the position of said optical unit so as to widen the view angle by the predetermined amount, prior to said plurality of times of image sensing on the subject.
An image sensing method comprising:
- widening a view angle by a predetermined amount;
- performing a plurality of times the image sensing on a subject by an image sensing unit that converts a subject optical image into an electric signal;
- and
- superpose-combining obtained plurality of subject images into one subject image.
A storage medium readable by a data processing apparatus, said storage storing a program which is executable by the data processing apparatus and comprises program code realizing the image sensing method comprising the steps of:
- widening a view angle by a predetermined amount;
- performing a plurality of times the image sensing on a subject by an image sensing unit that converts a subject optical image into an electric signal;
- and
- superpose-combining obtained plurality of subject images into one subject image.
