Abstract
Embodiments of the present application provide image processing methods and apparatus. A image processing method disclosed herein comprises: acquiring two images of the same scene shot in the same position with the same aperture pattern and different depth of field parameters; performing frequency-domain conversion on each of the images, to obtain a frequency-domain signal of each image; and obtaining an all-in-focus image of the scene at least according to the frequency-domain signal of each image and the different depth of field parameters.
Claims27
An image processing method, wherein the method comprises:
- acquiring two images of the same scene shot in the same position with the same aperture pattern and different depth of field parameters;
- performing frequency-domain conversion on each of the images, to obtain a frequency-domain signal of each image;
- and
- obtaining an all-in-focus image of the scene at least according to the frequency-domain signal of each image and the different depth of field parameters.
An image processing apparatus, wherein the apparatus comprises:
- an image acquisition module, configured to acquire two images of the same scene shot in the same position with the same aperture pattern and different depth of field parameters;
- a frequency-domain conversion module, configured to perform frequency-domain conversion on each of the images, to obtain a frequency-domain signal of each image;
- and
- a first processing module, configured to obtain an all-in-focus image of the scene at least according to the frequency-domain signal of each image and the different depth of field parameters.
A non-transitory computer-readable medium comprising executable instructions that, when executed by a processor of a device, cause the device with the processor to perform operations, comprising:
- acquiring two images of the same scene shot in the same position with the same aperture pattern and different depth of field parameters;
- performing frequency-domain conversion on each of the images, to obtain a frequency-domain signal of each image;
- and
- obtaining an all-in-focus image of the scene at least according to the frequency-domain signal of each image and the different depth of field parameters.
