An image processing device, comprising:
- a central processing unit (CPU) configured to:
- receive a first image captured by a first lens, and a second image captured by a second lens with a first specific focal length;
- generate a first pyramid image based on one of enlargement or reduction of the first image captured by the first lens;
- and
- calculate a focal length of the first lens based on the second image captured by the second lens with the first specific focal length, and the first pyramid image.
An image processing method, comprising:
- receiving a first image captured by a first lens, and a second image captured by a second lens with a specific focal length;
- generating a pyramid image based on one of enlargement or reduction of the first image captured by the first lens;
- and
- calculating a focal length of the first lens based on the second image captured by the second lens with the specific focal length, and the pyramid image.
A non-transitory computer-readable medium having stored thereon, computer-executable instructions which, when executed by a computer, cause the computer to execute operations, the operations comprising:
- receiving a first image captured by a first lens, and a second image captured by a second lens with a specific focal length;
- generating a pyramid image based on one of enlargement or reduction of the first image captured by the first lens;
- and
- calculating a focal length of the first lens based on the second image captured by the second lens with the specific focal length, and the pyramid image.
