Electronic device and method for processing multiple images
View Patent ↗A method for processing multiple images according to various embodiments of the present invention may comprise the operations of: acquiring multiple images by using multiple cameras; extracting image information for each of the acquired multiple images; preprocessing the multiple images on the basis of the extracted image information, and generating parameters corresponding to the multiple images, respectively; selecting one or more images required according to a zoom magnification among the acquired multiple images; and applying parameters corresponding to the selected one or more images and performing image processing. Other embodiments are possible.
1. An electronic device comprising:
a processor; and
a plurality of cameras configured to acquire multiple images;
wherein the processor is configured to:
extract image information on each of the acquired multiple images;
perform preprocessing for calculating at least one piece of auto focus (AF) data and auto exposure (AE) data of the multiple images on the basis of the extracted image information;
generate parameters corresponding to the respective images based on the extracted image information including phase difference information, an edge value, and an RGB channel value;
select one or more images required according to a zoom magnification from among the acquired multiple images; and
perform and synthesize image-processing of the one or more selected images from the acquired multiple images, based on parameters of the one or more selected images,
wherein the parameters include variables related to zoom adjustment, offset setting, and synchronization between the acquired multiple images.
2. The electronic device of claim 1 , further comprising a temporary storage device configured to perform control so as to temporarily store the one or more selected images in a memory or a buffer,
wherein the one or more images to be temporarily stored are stored in a RAW image format state or in a state in which parameters corresponding to the one or more images to be temporarily stored are applied.
3. The electronic device of claim 1 , wherein the processor is further configured to perform at least one of lens shading compensation and defective pixel correction.
4. The electronic device of claim 3 , wherein the processor is further configured to:
perform at least one of demosaicking, denoising and sharpening; or
if multiple images are selected, compensate for the difference in the field of view between the selected multiple images.
5. A method for processing multiple images, the method comprising:
acquiring multiple images using a plurality of cameras;
extracting image information on each of the acquired multiple images;
performing preprocessing for calculating at least one piece of auto focus (AF) data and auto exposure (AE) data of the multiple images on the basis of the extracted image information and generating parameters corresponding to the respective images based on the extracted image information including phase difference information, an edge value, and an RGB channel value;
selecting one or more images required according to a zoom magnification from among the acquired multiple images; and
performing and synthesizing image-processing of the one or more selected images from the acquired multiple images, based on parameters of the one or more selected images,
wherein the parameters include variables related to zoom adjustment, offset setting, and synchronization between the acquired multiple images.
6. The method of claim 5 , wherein the selecting one or more images required according to a zoom magnification from among the acquired multiple images further comprises temporarily storing the one or more selected images in a memory or a buffer, and
wherein the one or more images to be temporarily stored are stored in a RAW image format state or in a state in which parameters corresponding to the one or more images to be temporarily stored are applied.
7. The method of claim 5 , wherein the image-processing comprises:
first image-processing including at least one of lens shading compensation and defective pixel correction;
second image-processing including at least one of demosaicking, denoising and sharpening; or
third image-processing for, if multiple images are selected, compensating for the difference in the field of view between the selected multiple images.
8. The method of claim 5 , further comprising displaying, on a display, or storing, in a memory, the image acquired by performing the image-processing.
