Abstract
An imaging device for producing images of a scene, the imaging device comprising: a first and a second hyperchromatic lens being arranged in a stereoscopic configuration to receive light from the scene; image sensor circuitry configured to capture a first and second image of the light encountered by the first and the second lens respectively; processor circuitry configured to: produce depth information using the captured first and second images of the scene and produce a resultant first and second image of the scene using both the captured first and second image and the depth information.

An imaging device for producing images of a scene, the imaging device comprising:
- a first and a second hyperchromatic lens being arranged in a stereoscopic configuration to receive light from the scene;
- image sensor circuitry configured to capture a first and second image of the light encountered by the first and the second lens respectively;
- processor circuitry configured to:
- produce depth information using the captured first and second images of the scene and produce a resultant first and second image of the scene using both the captured first and second image and the depth information;
- partition the captured first and second images into regions corresponding to a resolution of the depth information;
- obtain for each region of the captured first and second images an image sharpness level for each colour channel using the depth information;
- determine for each region of the captured first and second image the colour channel having the highest sharpness level;
- produce the resultant first and second image of the scene by transporting for each region of each of the captured first and second images the image sharpness level from the colour channel having the highest sharpness level to the corresponding region in the complementary colour channels for that image;
- and
- perform a depth information propagation calculation to produce depth information having a resolution corresponding to the resolution of the captured first and second images and wherein each region corresponds to a single pixel.
