Abstract
A method for adjusting exposure parameters of images to be spliced and an image analyzing device are provided. The method includes: obtaining N images to be spliced into a panoramic image; obtaining a first brightness value of a first overlapping area and a second brightness value of a second overlapping area of each of the N images, and accordingly determining a first brightness ratio value and a second brightness ratio value of each of the N images; and determining a brightness ratio difference of each of the N images based on the first brightness ratio value and the second brightness ratio value of each of the N images, and accordingly updating an exposure parameter corresponding to each of the N images.
Claims12
A method for adjusting exposure parameters of images to be spliced, adapted to an image analyzing device, comprising:
- obtaining N images to be spliced into a panoramic image, wherein each of the N images comprises a first overlapping area and a second overlapping area, and N is an integer greater than 1;
- obtaining a first brightness value of the first overlapping area and a second brightness value of the second overlapping area of each of the N images, and accordingly determining a first brightness ratio value and a second brightness ratio value of each of the N images;
- and
- determining a brightness ratio difference of each of the N images based on the first brightness ratio value and the second brightness ratio value of each of the N images, and accordingly updating an exposure parameter corresponding to each of the N images.
An image analyzing device, comprising:
- a non-transitory storage circuit, storing a program code;
- and
- a processor, coupled to the non-transitory storage circuit and accessing the program code to execute:
- obtaining N images to be spliced into a panoramic image, wherein each of the N images comprises a first overlapping area and a second overlapping area, and N is an integer greater than 1;
- obtaining a first brightness value of the first overlapping area and a second brightness value of the second overlapping area of each of the N images, and accordingly determining a first brightness ratio value and a second brightness ratio value of each of the N images;
- and
- determining a brightness ratio difference of each of the N images based on the first brightness ratio value and the second brightness ratio value of each of the N images, and accordingly updating an exposure parameter corresponding to each of the N images.
