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.

Claims

1. A camera which can carry out image-taking in a first image-taking mode in which a synthesized image whose exposure has been corrected is obtained by synthesizing a plurality of images obtained through successive image-taking, and in a second image-taking mode in which an image corresponding to the synthesized image is obtained through one time of image-taking, comprising:

an image pickup device which photoelectrically converts an object image into an electric signal;

a sound production unit which makes sounds; and

a control unit which controls driving of the sound production unit,

wherein the control unit drives the sound production unit in timing with the first image-taking and the last image-taking during image-taking in the first image-taking mode, and in timing with image-taking start and image-taking completion during image-taking in the second image-taking mode.
