## Abstract

An image capture device includes first and second image sensors arranged to capture first and second images respectively of a same scene, each of the first and second images including pixel values; an objective lens associated with each of the image sensors, one objective lens being axially offset with respect to the other and having the same focal length as the other; a unit for analyzing the sharpness of each image; and a unit for selecting the image of desired sharpness.

## Claims

### Claim 1

An image capture device comprising:
first and second image sensors arranged to capture first and second images respectively of a same scene, each of the first and second images comprising pixel values;
an objective lens associated with each of the image sensors, one objective lens forming an image axially offset with respect to the other;
means for analyzing the sharpness of each of the images; and
means for selecting the image of desired sharpness.

### Claim 2 (depends on 1)

The image capture device of claim 1, wherein one of the objective lenses is axially offset with respect to the other and has the same focal length as the other.

### Claim 3 (depends on 1)

The image capture device of claim 1, capable of capturing color images, wherein the first and second image sensors are associated with first and second filters of a first color, further comprising:
a third image sensor associated with a third filter of a second color and a fourth image sensor associated with a fourth filter of a third color, all image sensors being arranged to capture an image of the same scene, an objective lens being associated with each of the image sensors; and
means for restoring a color image from pixels of the image selected by the selection means and from pixels corresponding to the images of the third and fourth image sensors.

### Claim 4 (depends on 3)

The image capture device of claim 3, wherein the first color is green and the second and third colors are blue and red.
