Method and apparatus for fusing a first image and a second image

An image processing apparatus, comprising:

• an acquiring module, configured to acquire a first image captured by a first camera lens and is about a first area, and a second image captured at a same moment by a second camera lens and is about a second area, wherein the first camera lens and the second camera lens are located on a same plane of the image processing apparatus;
• a translation compensating module, connected to the acquiring module and configured to:
• after the acquiring module obtains the first image and the second image, perform translation compensation on the second image by using the first image as a reference image;
• and
• an image fusion module, connected to the translation compensating module and configured to:
• after the translation compensating module performs translation compensation on the second image, fuse the first image and the second image that is obtained after translation compensation is performed, to generate a third image, wherein a resolution of the third image is higher than a resolution of the first image and a resolution of the second image;
• wherein the translation compensating module comprises:
• a first determining unit, configured to determine a translation vector between the first image and the second image, and
• a compensating unit, connected to the first determining unit and configured to:
• after the first determining unit determines the translation vector, perform, according to the translation vector, translation compensation on the second image captured by the second camera lens;
• wherein the determining unit is configured to determine the translation vector by using the following formula:
• d=B*f/Z;
• wherein:
• d indicates a translation vector of an object in the second image relative to the first image, wherein a distance between the object and a plane on which the first camera lens and the second camera lens are located is Z,
• B indicates a distance between the first camera lens and the second camera lens,
• Z indicates a vertical distance between the object and the plane on which the first camera lens and the second camera lens are located, and
• f indicates a focal length of the first camera lens or a focal length of the second camera lens.

A terminal, comprising:

• a first camera lens, configured to capture a first area to obtain a first image;
• a second camera lens, configured to capture a second area at a same moment when the first camera lens captures the first image, to obtain a second image, wherein the first camera lens and the second camera lens are located on a same side of the ten final;
• and
• a processor, connected to the first camera lens and the second camera lens, and configured to:
• perform translation compensation on the second image by using the first image as a reference image,
• fuse the first image and the second image that is obtained after translation compensation is performed, to generate a third image, wherein a resolution of the third image is higher than a resolution of the first image and a resolution of the second image,
• determine a translation vector between the first image and the second image, and
• perform, according to the translation vector, translation compensation on the second image captured by the second camera lens;
• wherein the processor is configured to determine the translation vector by using the following formula:
• d=B*f/Z;
• wherein:
• d indicates a translation vector of an object in the second image relative to the first image, wherein a distance between the object and a plane on which the first camera lens and the second camera lens are located is Z,
• B indicates a distance between the first camera lens and the second camera lens,
• Z indicates a vertical distance between the object and the plane on which the first camera lens and the second camera lens are located, and
• f indicates a focal length of the first camera lens or a focal length of the second camera lens.
