Abstract
An optical device for capturing an image of a scene, the optical device comprising: a plurality of image sensors each operable to capture a respective initial image of the scene; a lens arrangement operable to receive light from the scene and to form each initial image on each respective image sensor, each image sensor being located at a different respective distance from the lens arrangement; and an image processor operable to generate the captured image of the scene on the basis of image data from one or more of the captured initial images.

An optical scope system for capturing an image of a scene, the optical scope system comprising:
- a plurality of image sensors each operable to capture a respective initial image of the scene, each of the image sensors is operable to capture light using a different respective one of red, green and blue (RGB) color channels;
- and
- at least one lens to receive light from the scene and to form each initial image on each respective image sensor, each image sensor being located at a different respective distance from the at least one lens;
- and
- an image processor operable to:
- divide each of the captured initial images into predetermined portions;
- determine an image sharpness level for corresponding predetermined portions of each of the captured initial images;
- determine the highest one of the determined image sharpness levels;
- and
- generate, on the basis of image data from each of the captured initial images, the captured image of the scene so that a portion of the captured image of the scene corresponding to the corresponding predetermined portions of each of the captured initial images has a sharpness level equal to the determined highest image sharpness level, including
- transporting the image sharpness level of the one of the corresponding predetermined portions of the captured initial images which has the determined highest image sharpness level to the other corresponding predetermined portions of the captured initial images;
- and
- combining the one of the corresponding predetermined portions of the captured initial images which has the determined highest image sharpness level with the other corresponding predetermined portions of the captured initial images to which the determined highest image sharpness level has been transported.
A method of capturing an image of a scene in an optical scope system, the method comprising:
- capturing a plurality of initial images of the scene, each initial image of the scene being captured using a respective one of a plurality of image sensors, wherein each image sensor is located at a different respective distance from at least one lens to receive light from the scene and to form each initial image on each respective image sensor, each of the image sensors is operable to capture light using a different respective one of red, green and blue (RGB) color channels r;
- dividing each of the captured initial images into predetermined portions;
- determine an image sharpness level for corresponding predetermined portions of each of the captured initial images;
- determining the highest one of the determined image sharpness levels;
- and
- generating, on the basis of image data from each of the captured initial images, the captured image of the scene so that a portion of the captured image of the scene corresponding to the corresponding predetermined portions of each of the captured initial images has a sharpness level equal to the determined highest image sharpness level generating including
- transporting the image sharpness level of the one of the corresponding predetermined portions of the captured initial images which has the determined highest image sharpness level to the other corresponding predetermined portions of the captured initial images;
- and
- combining the one of the corresponding predetermined portions of the captured initial images which has the determined highest image sharpness level with the other corresponding predetermined portions of the captured initial images to which the determined highest image sharpness level has been transported.
