Imaging Apparatus and Imaging Method
First Claim
1. An imaging apparatus having a function of combining a plurality of images captured under different exposure conditions, comprising:
- a detecting means for detecting positional deviation among the plurality of images and blurring amounts anda combining means for setting a ratio in combination of images according to a distance from an edge extracted based on detection results of the detecting means and combining images with the set ratio.

Abstract
An imaging apparatus and an imaging method able to obtain images having no blurring with a small number of images under different exposure conditions and capable of shortening a processing time, wherein an imaging apparatus 10 captures a plurality of images including an image having a short exposure time and high resolution, but having much noise and an image having a long exposure time, but having little noise and low resolution by an optical system 11 and an imaging element 12. After the signal processing of a signal processing part 13, a CPU 14 detects positional deviation among the captured images and blurring, changes the ratio of the plurality of images according to the distances from the edge, and combines these to thereby form an image free from blurring and reducing noise.
