IMAGING DEVICE AND IMAGING DEVICE CONTROL METHOD
First Claim
1. An imaging device, comprising:
- an imaging section for photoelectrically converting a subject image formed by a photographing lens and outputting image data;
an aperture control section, arranged on the optical path of the photographing lens, for narrowing subject light flux at a first aperture value and a second aperture value;
a shooting control section for, in response to a release instruction, imaging a first image at the first aperture value and, after completion of imaging of the first image, reading out first image data from the imaging section while at the same time carrying out a stopping down operation to the second aperture value using the aperture control section, imaging a second image at the second aperture value and, after completion of imaging of the second image, reading out second image data from the imaging section; and
an image processing section for detecting an amount of variation in contrast value for each location in the first image data and the second image data, and carrying out processing to blur at an intensity of blurring according to the amount of variation for each location in the first image data and the second image data.
