Using narrow field of view monochrome camera for producing a zoomed image
First Claim
Patent Images
1. A method implemented by a processor of an electronic device for producing an enhanced image, the method comprising:
- receiving an instruction to adjust a digital zoom level of the color camera;
receiving a color image that is captured by a color camera;
receiving an achromatic image that is captured by a monochrome camera, the monochrome camera having a narrower field of view than the color camera, the monochrome camera generating the achromatic image based on visible light, wherein the monochrome camera and the color camera have a common resolution for capturing images, and wherein the achromatic image has more detail than the color image;
after capturing the color image, cropping the color image based on the adjusted digital zoom level of the color camera to obtain a cropped color image; and
merging the cropped color image and the achromatic image to produce an enhanced image that has a higher level of detail than the color image.

Abstract
Methods and electronic devices for producing a zoomed image using a narrow field of view monochrome camera are described. In one aspect, the method includes: receiving a color image that is captured by a color camera; receiving an achromatic image that is captured by a monochrome camera with the monochrome camera having a narrower field of view than the color camera; and merging the color image and the achromatic image to produce an enhanced image.

11. An electronic device for producing an enhanced image, the electronic device comprising:
-
a memory; a color camera and a monochrome camera; and a processor coupled with the memory, the color camera, and the monochrome camera, the processor being configured to; receive an instruction to adjust a digital zoom level of the color camera; receive a color image that is captured by the color camera; receive an achromatic image that is captured by the monochrome camera, the monochrome camera having a narrower field of view than the color camera, the monochrome camera generating the achromatic image based on visible light, wherein the monochrome camera and the color camera have a common resolution for capturing images, and wherein the achromatic image has more detail than the color image; after capturing the color image, crop the color image based on the adjusted digital zoom level of the color camera to obtain a cropped color image; and merge the cropped color image and the achromatic image to produce an enhanced image that has a higher level of detail than the color image. - View Dependent Claims (12, 13, 14, 15)

16. A non-transitory computer readable storage medium comprising computer executable instructions for producing an enhanced image, the computer executable instructions including instructions for:
-
receiving an instruction to adjust a digital zoom level of the color camera; receiving a color image that is captured by a color camera; receiving an achromatic image that is captured by a monochrome camera, the monochrome camera having a narrower field of view than the color camera, the monochrome camera generating the achromatic image based on visible light, wherein the monochrome camera and the color camera have a common resolution for capturing images, and wherein the achromatic image has more detail than the color image; after capturing the color image, cropping the color image based on the adjusted digital zoom level of the color camera to obtain a cropped color image; and merging the cropped color image and the achromatic image to produce an enhanced image that has a higher level of detail than the color image.
