Abstract
A camera which can obtain an image without image blur is disclosed. The camera which obtains a synthesized image whose exposure has been corrected by synthesizing a plurality of images obtained through successive image-taking, comprising: a detection unit which detects, with respect to a reference image, amounts of displacement on other images; a coordinate conversion unit which applies coordinate conversion to the other images based on the results of detection of the detection unit; and a synthesis unit which synthesizes the other images subjected to coordinate conversion and the reference image.
Claims12
An image-pickup apparatus which obtains a synthesized image whose exposure has been corrected by synthesizing a plurality of images taken successively, comprising:
- a focusing unit which operates a focusing operation to move a focus lens system of the image-pickup apparatus based on a signal of a focused region;
- an obtainment unit which obtains a focused condition within the focused region;
- a detection unit which detects, with respect to a reference image, amounts of displacement on other images, wherein the detection unit divides the reference image into a first region including the focused region by the focusing operation of the lens system on the reference image and a second region other than the first region, and detects the amounts of displacement based on a specific part in the second region of the reference image and specific parts of the other images in respective regions corresponding to the second region;
- and
- a synthesis unit which synthesizes the plurality of images based on the results of detection of the detection unit
A method for obtaining a synthesized image whose exposure has been corrected by synthesizing a plurality of images taken successively through a lens system, a focusing unit which operates a focusing operation to move a focus lens system of an image-pickup apparatus based on a signal of a focused region, comprising:
- an obtainment step which obtains a focused condition within the focused region;
- a detection step in which, with respect to a reference image, amounts of displacement on other images are detected, wherein, in the detection step, the reference image is divided into a first region including the focused region by the focusing operation of the lens system on the reference image and a second region other than the first region, and the amounts of displacement are detected based on a specific part in the second region of the reference image and specific parts of the other images in respective regions corresponding to the second region;
- and
- a synthesis step in which the plurality of images are synthesized based on the results of detection of the detection step.
An image-pickup apparatus which obtains a synthesized image whose exposure has been corrected by synthesizing a plurality of images taken successively through a lens system, a focusing unit which operates a focusing operation to move a focus lens system based on a signal of a focused region, comprising:
- an obtainment unit which obtains a focused condition within the focused region based on a stopping position of the focus lens in the lens system;
- a detection unit which detects, with respect to a reference image, amounts of displacement on other images, wherein the detection unit divides the reference image into a first region including the focused region by the focusing operation of the lens system on the reference image and a second region other than the first region, and detects the amounts of displacement based on a specific part in the second region of the reference image and specific part of the other images in respective regions corresponding to the second region of the other images;
- and
- a synthesis unit which synthesizes the plurality of images based on the results of the detection unit.
